~~~~~~
Jack and the Doctor had received strict instructions from Martha Jones to be in Bannerman Road at exactly 11.30 am on Sarah Jane's birthday, and neither one dared risk being late. Martha was waiting on the corner when the TARDIS materialised five minutes early. The Time Lord had barely stepped out of the door when Jack pulled up opposite and crossed the road to join them.
Martha hadn't worked out how she was going to greet the Doctor: it was the first time they'd met since her rather memorable birthday a few weeks ago, but since Jack got to her first and immediately swooped in and picked her up in a hug, she didn't have time to worry about it.
"Hello gorgeous." He kissed her thoroughly, then set her back down on her feet.
"Hello Jack." Martha turned to the Doctor, feeling a little hesitant but he gave her a wink, then followed Jack's example. She relaxed into his arms with relief.
Jack’s cheery laugh shook her out of her reverie and she saw him looking from one to the other. "You sly pair!" he exclaimed. "You two got together and neither one of you told me?"
"Not exactly," Martha answered.
"You'd better spill the beans later," he told her. "But since you were the one who insisted we arrive on time, hadn't we better move?"
She nodded and led the way to Sarah Jane's house.
"Does she know we're coming?" asked Jack.
"No, I wanted it to be a surprise. The kids are giving her a party tomorrow since they're at school today, but I wanted Sarah Jane to celebrate on her birthday itself so I swapped my usual afternoon off and said we'd go out for lunch. I just didn't say where or who we'd be lunching with." Martha rang the doorbell, then stepped back between Jack and the Doctor.
Sarah Jane opened the door and stared in surprise at the three people on her doorstep.
"Happy birthday Sarah Jane," they chorused spontaneously.
She put her hands to her mouth, but whether she wanted to laugh or cry wasn't clear. The Doctor immediately stepped forward and pulled her into a hug, kissing the side of her neck. "OK?" he asked softly.
"Yes I'm OK," she said after a moment. "Just very surprised."
The Doctor pulled back a little, then bent his head to kiss her properly.
Jack turned to Martha, his eyes wide with surprise. "Seems to me that I've been left out of the loop completely."
Martha blushed. "Sorry Jack, but I have been rather busy the last few weeks, as have you."
"Even so, you might have found the time to tell me!"
He turned to greet Sarah Jane, hugging and kissing her as he had Martha earlier. "Happy birthday Sarah Jane." He set her down on her feet again.
"Thank you Jack."
She turned to Martha, who was feeling even more nervous now. She wasn't sure Jack was going to quickly forgive her for not keeping him informed of what was going on with his friends. She took a deep breath, then stepped forward to hug Sarah Jane, who kissed her. Martha heard Jack's sharp intake of breath, behind Sarah Jane, then an 'oof' and she wondered if the Doctor had elbowed him..
Sarah Jane pulled away and turned, her arm firmly around Martha. "Jack Harkness, are you jealous?" she asked disbelievingly.
"I'm jealous of you three getting together and not inviting or telling me," he answered, looking at his three friends.
"Shall we go and sit down and talk about this?" the Doctor suggested.
They moved into the sitting room and Jack sat down on one side of Sarah Jane whilst the Doctor sat on the other. Since the sofa wasn't big enough for four, the Doctor pulled Martha down onto his lap and she sat sideways, one arm around his neck.
"So," Jack said, "tell me how and when you three ended up on kissing terms, especially you two." He nodded at Sarah Jane and Martha.
Sarah Jane began, reminding Jack that he'd told her about Martha's birthday and explaining that she'd bought pizza and wine for lunch: then Martha took up the story recounting how she'd talked to Sarah Jane about what had happened during the year that the Doctor had rewound, and that she'd drunk so much that Sarah Jane had suggested she try sleeping it off, and they'd ended up kissing.
"Things rather escalated from there," Martha said. "And then the Doctor turned up to see Sarah Jane and we - " She paused, slightly embarrassed now that she was telling Jack.
"They jumped me," the Doctor interrupted. "And stripped me, then we all made love."
"Well!" Jack appeared, for once, almost speechless.
"Anyway, today's Sarah Jane's birthday," the Doctor said. "So we're taking you out to lunch and treating you."
"Is there anywhere you'd like to visit?" Martha asked.
"Actually, would it be very staid of me to ask if we could have lunch on the TARDIS?" Sarah Jane asked. "I haven't explored her with her new look and I'd quite like to, if that's OK?"
The Doctor nodded. "Of course - it's your day, we'll do whatever you like." He lifted Martha off his lap and stood, offering Sarah Jane his hand. He led the way to the TARDIS, Sarah Jane's hand firmly clasped in his own.
Martha and Jack followed. "Are you very mad at me?" she asked him.
"I'm not mad at all," he answered. "Just disappointed you didn't tell me any of this sooner, especially the bit about the Doctor catching you and Sarah Jane."
"I am sorry, Jack - I wanted to tell you. I was going to invite you up for a visit and tell you, but I've been so busy. And I thought it would be better to tell you in person rather than on the phone or in an email."
He pulled her into a hug. "It's OK - I'll forgive you - but next time don’t leave me out of the fun!" He bent his head to kiss her and Martha slid her arms up around his neck.
"Are you two coming?" asked the Doctor.
"Not yet," answered Jack cheekily, which earned him an eye roll from the Doctor and a swat on the arm from Martha. He just laughed as he followed Martha into the TARDIS, his hand in the small of her back.
The Doctor was standing by the console. "I thought I'd put her into the Time Vortex, so we can have as much time as we want for lunch and showing Sarah Jane around the TARDIS. That way she doesn't have to worry about rushing back in time for Luke to get back from school."
His Companions nodded agreement, so the Doctor moved around the console to dematerialise his ship and the others piled onto the Captain's chair, Sarah Jane in the middle.
"I like your dress," Sarah Jane told Martha. "I haven't seen that one before."
"It's my 'party frock'," she answered. "And I don't think I've worn it since the Lazarus business. I wore it today because I thought we might be going to a nice restaurant."
The TARDIS gave a shudder and they knew that they were in the Vortex. The Doctor joined them.
"Shall we?" He held out a hand to Sarah Jane, who took it and allowed him to lead her down the corridors. "Martha, why don't you show Sarah Jane the library and the Med Bay, and the rooms around there, whilst Jack and I make lunch. Then we'll do the proper tour after we've eaten?" He turned to Jack. "Is that OK?"
"I'm easy," Jack answered.
"I think we all knew that Jack," Martha murmured to snorts of laughter from the Time Lord and Sarah Jane.
Jack stared at her, open mouthed. "You are getting seriously cheeky," he said, wagging a finger, but the broad grin on his face belied any attempt at menace.
"To be fair, you asked for that," the Doctor told him. "Come on, let's get started on lunch."
Martha led Sarah Jane out of the kitchen and down the corridor to the Med Bay. She wasn't very surprised when Sarah Jane almost immediately backed her up against one of the beds and began raining hungry kisses on her neck and face.
"I've missed you," she murmured.
"I've missed you too," Martha said. "I'm sorry I haven't been around the last couple of weeks. Work - "
"Never mind work," Sarah Jane said. "You're here now." She ran her hands down Martha's sides, then hitched up the hem of her dress and slid her hand up the younger woman's leg to her thigh. She drew her hand higher, seeking Martha's entrance and found her thong was already wet.
"I want to taste you," she told Martha, her voice husky with longing as she pulled her thong off.
Martha pulled herself up onto the bed, then Sarah Jane pushed her dress up to bare her thighs, which she gently parted, before dragging her tongue up Martha's wet folds.
"Oh god!" Martha clutched the edge of the bed with one hand and put her other hand on Sarah Jane's shoulder. She whimpered as Sarah Jane used her teeth and tongue to good effect, the older woman holding her steady. Martha's whimpers soon turned to moans as Sarah Jane curled her tongue inside Martha and brought her to a climax.
Tremors ran through Martha's body as Sarah Jane pulled away, then straightened up and leaned in to kiss the younger woman: Martha opened her mouth to Sarah Jane's kiss, tasting herself on the older woman's mouth.
"Jack's going to be so disappointed he missed that," Martha said with a guilty giggle when they pulled apart.
"Maybe we should do it again later and let him watch?" Sarah Jane suggested.
Martha stared. "Are you - You're serious, aren't you?" she asked.
Sarah Jane nodded, a mischievous grin on her face.
"Wow!" Martha decided she didn't know what else to say to that.
"Would you mind?"
Martha shrugged. "I don't know. Probably not. Knowing Jack, though he'd want to join in."
"That could be fun," Sarah Jane said, grinning again. "Come on, you were going to show me the Library."
Martha nodded, then slid down off the bed and retrieved her thong.
"Leave it off," Sarah Jane said. "Please?"
"Sarah Jane Smith, I do believe you're turning into a wicked woman!" Martha exclaimed only half seriously.
"More interesting than being a sweet old lady," she answered as Martha pocketed her thong, then she slid her arm through Martha's as they went out and up the corridor to the library.
"Old!" snorted Martha. "You'll never be old."
Sarah Jane laughed, but didn't bother arguing the point as they began to wander amongst the shelves.
"You know, when I was a student, I always had a fantasy about having sex in the library," Martha observed.
"And did you ever do it?"
Martha shook her head. "I didn't date much when I was a student, and I never dared to mention it to anyone."
"We should do it." She arched an eyebrow at the younger woman's look of surprise. "You must want to, or why did you mention it?"
"I spoke without thinking," Martha said.
"That I'll never believe," Sarah Jane retorted. "You always think before you speak."
"What if Jack or the Doctor finds us?"
"They can watch, or join in, as they see fit." She guided Martha over to a sofa and sat down, pulling Martha down onto her lap and began to kiss her.
After a few minutes Martha pulled away, then stood up and pushed Sarah Jane's skirt up.
"Easier if I take it off," she said, standing up and slipping out of it. Martha stepped in closer and kissed her again, before hooking her thumbs into the waistband of Sarah Jane's knickers and sliding them down. Sarah Jane allowed them to drop to the floor, then stepped out of them and her skirt, before sitting down again.
"My turn to taste you," Martha said, before kneeling at the older woman's feet. She pushed Sarah Jane's legs apart, sliding her hands up Sarah Jane's thighs then leaning forward to press her nose and mouth into Sarah Jane's curls.
Sarah Jane sighed as Martha lapped at her, gently increasing the pressure of her tongue and building her steadily towards her climax. They'd done this often enough that Martha knew the precise moment when Sarah Jane was ready to come, and at that moment she hummed, knowing the vibration would be enough to send Sarah Jane over the edge. Sure enough, there was a strangled cry above her and Sarah Jane jerked in release. Martha stayed where she was for several minutes, enjoying the fruits of her efforts, before getting up and straddling Sarah Jane.
"OK?" she asked her friend softly. Sarah Jane gave her a dazed nod and Martha smiled, before leaning in to kiss her again.
Martha wasn't very surprised when Sarah Jane's fingers sought her core as they continued to kiss. She slid a hand down between their bodies and slipped a finger inside to stroke Sarah Jane's sensitive flesh. Martha used her other hand to unbutton her friend's shirt, then cupped her breast, rubbing her thumb over Sarah Jane's hardening nipple.
"Martha!" Sarah Jane pulled back, gasping her friend's name, breathing heavily. "Don't stop."
"No stopping," Martha agreed, moving her fingers faster, and stroking the older woman's breast more firmly. She pinched the nipple between thumb and forefinger and Sarah Jane gasped again.
"Tormentor," Sarah Jane said breathlessly.
Martha stilled her hands. "Well if you want me to stop - But I could have sworn you told me not to, just now." She grinned mischievously.
"I swear Jack's taught you some bad habits, young lady," Sarah Jane said as severely as she could manage. "I - "
Whatever else she was going to say was lost in an incoherent mumble as Martha curled her fingers inside Sarah Jane and made her come. She continued to stroke Sarah Jane through her orgasm, then pulled her fingers free and began to suck them clean, eyes half closed in pleasure.
As soon as Sarah Jane could think straight again, she upped the pace of her own touches wanting Martha to come too.
"Ah!"
Martha was always very quiet when she came and Sarah Jane occasionally wondered what it would take to make her friend scream. They rested their foreheads together, waiting for their heartrates to settle.
"Happy birthday, Sarah Jane," Martha said quietly.
"Thank you." They smiled lazily at one another, before Martha moved so that Sarah Jane could dress again.
* * * * * *
In the TARDIS kitchen, the Doctor began to open cupboard doors.
"Are we going to have a proper sit-down lunch?" Jack asked as he leant against the counter.
"Nah, I thought a picnic would be nicer - I know the perfect spot."
"Here on the TARDIS?" Jack asked, surprised.
The Doctor quirked an eyebrow at him. "It's bigger on the inside," he said gently.
"Well I know that, I just didn't realise she had any outdoor areas - you've never shown me those."
"I haven't shown Martha either. Haven't been in any of them since before - " He didn't finish but he didn't have to, Jack knew he meant before the Time War. He clasped the Doctor's shoulder and the Time Lord smiled at him.
"There's a picnic hamper in that cupboard," the Doctor told him, pointing. "If you get that out, and the plates and stuff that are in the cupboard with it, I'll start sorting out food."
"OK."
They had just finished packing the hamper, when Martha and Sarah Jane arrived. Jack took one look at them and grinned.
"What's amusing you, Captain?" Martha asked.
"Oh nothing," he said, but his grin got wider.
The Doctor looked up from fastening the hamper shut and grinned too, which Sarah Jane immediately noticed.
"What?" she asked.
"I think you two must have had a nice tour," the Doctor commented, watching them both closely. "Although I have a funny feeling you didn't see much of the TARDIS."
"Bet they saw a lot of each other though," Jack commented.
"I don't know what you're talking about," Martha said, trying to look nonchalant.
"Liar," Jack teased, pulling her closer. "You're glowing, both of you." He bent his head and nuzzled the side of her neck.
"And the smell of pheromones has increased," the Doctor added.
Sarah Jane stared at him, open-mouthed. "You can smell pheromones?" she asked.
He nodded, grinning still.
"You never told me that before," Sarah Jane commented.
"You didn't need to know." He pulled her into a hug. "I'm glad you two have each other," he said quietly so only she could hear.
"Right, then - lunch," he said more loudly. "We've packed a picnic and if you two ladies would care to accompany us, I know a nice spot where we can enjoy ourselves." He let go of Sarah Jane and picked up the picnic hamper, then led the way out into the corridor. The others followed as the Doctor led them deeper into the TARDIS until he stopped and opened a door with a flourish, gesturing for them to precede him.
"Wow!" murmured Martha, staring around. They seemed to be standing in a meadow and at first she wasn't sure if it was real or a clever hologram: did the TARDIS have a holosuite, like ships on Star Trek, she wondered. It seemed real: she could feel warmth on her skin from the sun, and there was a slight breeze too. She inhaled and smelt honeysuckle and something lemony, and she could hear birds somewhere. Shading her eyes with one hand she looked up and saw the sky was a lilac colour.
Jack and Sarah Jane seemed to be speechless, and the Doctor grinned as he stepped in front of them. "Come on then, we're not quite there yet." He led the way across the springy yellow turf, practically bouncing along.
Martha stopped and bounced up and down experimentally on the balls of her feet. "Wow!" She looked up at Jack and Sarah Jane. "It feels more like a mattress than grass," she said. She stooped to unfasten her shoes.
"Let me," Jack said, kneeling at her feet. He deftly undid the buckles and Martha stood on one foot, then the other as he helped her to take off her shoes. He slid a finger up her leg to caress the back of her knee, grinning up at her, before getting up again.
"Tease," she muttered.
"You're a fine one to talk," he retorted, before turning to Sarah Jane to help her to take off her shoes too. He didn't hesitate to caress Sarah Jane's legs as well, before getting back up and holding out a hand to each of them.
They caught up with the Doctor and he led them across the meadow and into an area of woodland.
"Hey Doc, is it much further?" Jack asked.
"Nope," he answered, popping the 'p' before grinning at his three Companions. "You're gonna love this."
About ten minutes later they found themselves on the shore of a small lake that was fed by a waterfall: the water was a startling blue.
The Doctor set down the picnic hamper and grinned at his Companions again, their wide-eyed looks showing how well he'd surprised them. "So, who wants a swim before lunch?" he asked.
Martha looked up from staring into the lake. "You brought swimwear along with the picnic?"
"Martha, shame on you," Jack teased. "You've made love to all of us at one time or another: you're not gonna be shy about skinny dipping with us?"
"Oh." She looked away, embarrassed, and Sarah Jane immediately put an arm around her.
Jack stepped up behind them and put his arms around Martha's middle. "You're not really that shy, are you?" he asked.
"I s’pose not," she mumbled.
He kissed the side of her neck. "Good." He pulled away, then started to undress, winking at her when he saw her watching.
Sarah Jane moved behind her to unzip her dress and the Doctor stepped in front of her, stroking a finger down her face. "Can you help me with my buttons?" he asked.
Martha grinned and quickly began unbuttoning his shirt, then stopped to pull his tie undone. In a few moments, they were all naked and Jack was the first to wade out into the water.
"Oooh, it's warm," he called. "Come on you guys, it's lovely!"
The others waded into the water together, Sarah Jane holding Martha's hand on one side and the Doctor on the other. Jack wasted no time in splashing the three of them with double handfuls of water and they immediately dived at him, knocking him off his feet. Within seconds they were engaged in an intense water battle and the air was filled with shrieks and laughter. Martha leapt on Jack's back when he was trying to catch Sarah Jane, wrapping her arms and legs around him in an attempt to stop him.
"Help!" he called. "I've got a human limpet."
The Doctor laughed aloud, whilst Sarah Jane giggled. "You're on your own," she told him: she and the Doctor waded ashore soon afterwards, leaving Jack to try to dislodge Martha.
"OK, I give up, you win," he told her and waded ashore too.
She immediately slid off him and struck a triumphant pose, before flopping down onto the grass next to Sarah Jane. "Are we eating now?" she asked the Doctor.
He nodded and sat up to unfasten the picnic hamper. He passed out plates and sandwiches, then spread out a picnic rug and put some dishes in the middle. "Dips," he told them. He put a handful of spoons beside the dishes, then got out four wine glasses and a bottle of wine.
"Help yourselves," he said, digging into the pocket of his discarded jacket for his Sonic Screwdriver so he could zap the cork out.
"Show off," muttered Jack.
"You're just jealous 'cos you haven't got one," Martha teased. He pouted at her, making her giggle.
The Doctor handed round glasses of wine. "To Sarah Jane," he said, grinning at her.
"To Sarah Jane," echoed Martha and Jack. "Happy birthday," Martha added.
"Thank you." They settled around the rug, talking and eating as they caught up on each other's news. It was pleasantly warm and Martha felt relaxed enough not to mind that they were all still naked.
Much later, she wasn't surprised that Jack was the one to make the first move. She was eating a spoonful of tangy dip and some dripped off the spoon onto her arm. Before she could move, Jack was dragging his tongue across her skin, scooping up the dip in the process.
"You're incorrigible," she told him, the words coming out more breathily than she had intended.
"And you're delicious," he answered in a teasing tone, leaning in and kissing her, one hand holding the back of her head.
When he pulled back, he smacked his lips. "Mmm, nice." He then scooped up a spoonful of the dip and dropped some onto Sarah Jane's leg.
"Jack!" she protested half-heartedly.
"Can't leave the birthday girl out, can I?" he asked before licking it off, then dragging his tongue further up her leg. He kissed her as he'd kissed Martha, then moved across to the Doctor.
"Fair's fair," he murmured before dripping the dip onto the Doctor's leg.
Martha felt her breath hitch as she watched Jack kiss the Doctor, then Sarah Jane was at her side, nuzzling her neck. When Sarah Jane moved from kissing her neck to her mouth, Martha forgot all about Jack and the Doctor: she closed her eyes with a sigh and failed to notice that the two men were watching them.
"Lie down," Sarah Jane murmured when she pulled away.
Martha opened her eyes again, looking at Sarah Jane nervously. "I don't know if I can do this," she said softly.
Sarah Jane stroked a finger down her cheek. "It's OK. You're safe here. You're with friends who love you. Close your eyes and relax." She leant forward to whisper in Martha's ear. "Besides, Jack and the Doctor are busy at the moment."
Martha's eyes widened in surprise and she peeked around Sarah Jane to see that they weren't being watched now. She lay down and stretched out on her back, closing her eyes again as she enjoyed Sarah Jane's caresses, which moved lower and lower until she slipped a finger inside Martha's heat, eliciting a soft moan.
Behind them, Jack was kissing the Doctor, his left hand cupping the back of the Time Lord's head, whilst his right hand was gently stroking the Doctor's length. Jack had wanted this for such a long time, but he'd never believed he'd have the chance to do this with the Doctor.
"Will you come for me?" Jack asked him quietly as he felt the Doctor's cock stiffening in his hand.
The Time Lord nodded, eyes dark with desire, and Jack leant in to kiss him again, continuing to stroke his growing erection at a steady pace. The Doctor kissed him fervently and Jack savoured the taste of the Time Lord's mouth as his tongue explored its cool interior.
"Jack!" There was a note of warning in the Doctor's voice, then he was clutching at the younger man's shoulders as he came hard. He fell back onto the turf and Jack stretched out beside him, holding the Time Lord as he caught his breath.
When he'd recovered Jack and the Doctor moved quietly across the grass as Martha turned onto her side and hooked her leg over Sarah Jane's leg. Martha stroked her hand down Sarah Jane's side, then across her stomach, before sliding a finger into her.
They were so intent on each other, that Jack had moved behind Sarah Jane and the Doctor had lain down behind Martha without either woman noticing their presence, until other hands began to caress them.
"That feels nice," Sarah Jane said quietly as Jack pressed himself against her back, leaning on his right elbow, then reached round to stroke his left hand up from her stomach to her breasts.
He began kissing the back of her neck and her left shoulder. "It does, doesn't it?" he murmured.
The Doctor was stroking his right hand up and down Martha's thigh whilst kissing her: she had turned her head towards the Doctor's once she was aware he was there.
She could feel his erection pressing against her and she pulled her mouth from his. "Make love to me?" she asked him.
"I thought you'd never ask," he answered with a smile. He slid his right hand under her leg and lifted it from Sarah Jane's so that he could slide inside her even as Sarah Jane continued to tease her.
The older woman smiled at them both, then sighed as Jack followed the Doctor's example, sliding his erection into Sarah Jane from behind.
"OK?" Jack asked her.
"Oh yes," she murmured.
It didn't take either woman long to reach a climax with such a double stimulus, and neither the Doctor nor Jack was able to last much longer afterwards. The four of them dozed for a while, arms and legs tangled together.
Predictably the Doctor was the first to stir and although he tried not to wake the others, his three Companions responded to his wakefulness. He smiled ruefully when three pairs of eyes turned his way.
"Anyone want to swim?" he asked.
There were murmurs of agreement and a moment later all four of them were in the water again, heading across the lake to the waterfall. They pulled themselves out of the lake to sit on the rocks either side of the cascade, Jack and Martha sitting on one side, whilst the Doctor sat with Sarah Jane on the other.
Jack pulled Martha's legs across his, so that she was sitting at a right angle to him and slid an arm around her waist. "You've become properly adventurous," he commented, looking across at Sarah Jane and the Doctor.
She raised her eyebrows. "I wonder whose influence is responsible?"
He chuckled. "Glad to know I haven't lost my touch," he said.
"Not yet," Martha answered. She reached up and cradled his cheek before leaning in to kiss him and he immediately lifted her up to sit on his thighs. He deepened the kiss as he slid his left hand up her leg from her shin to her thigh.
"Insatiable," she murmured when they pulled apart to catch their breath.
"Gorgeous," he answered.
Martha stood up, holding his shoulders so she didn't lose her balance on the wet rocks, then turned and sat down again facing him. As they kissed, she stroked his growing erection until he lifted her up then lowered her slowly so that he could slide inside her. She wrapped her left arm around his shoulders, then tangled the fingers of her right hand in his hair and pulled his head closer so she could kiss him again.
They rocked together gently at first, then Jack slid a hand between their bodies and began to stroke her clit and she felt her arousal building. He soon pulled his hand free and grasped her bottom, lifting her up and down his length as she clutched at his shoulders.
"Come for me, Martha," Jack whispered into her neck and she shuddered to a climax, her muscles clenching hard around his cock, which was enough to drive him over the edge.
Afterwards Jack stroked a hand up and down her spine as she slumped against him, her head resting on his shoulder. "OK sweetheart?"
"Yeah."
"You need some more calories," he asserted. "All this sex must be burning them up, and you're not carrying any spare."
Martha felt herself blushing at his reference to the amount of sex she'd enjoyed today and felt glad that her face was still buried in the crook of his neck. He stood up, lifting her easily, and Martha felt him slip out of her before he stepped down into the lake and waded across to where the Doctor was helping Sarah Jane down from their rocky perch. The four of them climbed up onto the grass and walked back around the lake to their picnic spot, all of them feeling too tired to swim again for the moment.
Martha flopped down onto the grass. "Don't ask me to move again for an hour," she begged.
"I don't know, young people today have no stamina," the Doctor said, with a grin.
Martha stuck her tongue out at him as Jack sat down behind her and pulled her back to lean against his chest.
"You just need more calories," he repeated, rummaging in the picnic basket and pulling out a tub of ice cream.
"You better not hog that Harkness," warned the Doctor, pulling more spoons out of the hamper and offering them around.
"How does it stay cold?" Martha asked, peering at the hamper.
"Time Lord technology," the Doctor answered, cryptically.
Jack ignored the Time Lord's warning in favour of opening the tub of ice cream and digging out a spoonful to feed Martha. It didn't take long for the four of them to demolish the entire tub, then the Doctor got out a bowl of strawberries and two covered dishes. He uncovered the them and Martha saw one contained cream and the other a chocolate sauce.
"You certainly didn't consider our waistlines, did you?" Sarah Jane asked.
"Oh well if you don't want any," teased the Doctor, passing the dishes to Martha.
Sarah Jane stuck her tongue out at him, then turned her back on him very pointedly and dipped a strawberry in the cream, before offering it to Martha. Sarah Jane jumped a moment later, when the Doctor sat behind her and wrapped an arm around her middle, before offering her a chocolate-dipped strawberry.
After they finished the strawberries, they drank more wine and reminisced, lying in the grass once the wine was finished. As they talked Martha noticed the sky was gradually growing darker until stars came out above them.
"Where are we?" she asked.
"On the TARDIS," answered the Doctor.
"So why's it got dark? I thought there wasn't any time here when we're in the Vortex?"
"There isn't. That's a holographic projection. I thought you might like to see the stars with me again."
Martha rolled onto her side, from her place beside Jack, and putting her weight on her elbow, leant towards him. "You’re quite sweet, you know?" She bent her head and kissed him gently.
"Thank you," he murmured.
Sarah Jane sat up on the Doctor's other side. "Thank you all for a lovely birthday."
"You're welcome, my Sarah Jane," the Doctor answered pulling her into a hug, then kissing her heartily.
"Any time," Jack answered, moving to her side to follow the Doctor's example. He pulled away and let Martha take his place.
"I'll see you again next week," she said.
Sarah Jane nodded, then they pulled on their clothes as the lights came back up, and helped the Doctor to pack everything back into the hamper which he left in the kitchen before they went back to the Control Room.
A few minutes later the TARDIS materialised in Sarah Jane's back garden and the Doctor waved them off. Jack headed back to his SUV, promising to visit them both soon.
"Cup of tea before you go?" Sarah Jane asked Martha.
"Yes please."
They headed inside together, each with an arm wrapped around the other.
