 “The thought has crossed my mind!”
He slapped a hand to his helm, voicing aloud rather than over the comm channels. “Primus this is great, he's got you, too.”
Prowl's face smoothed of any anger. She took his hand and pulled it away from his head. He turned away from her when she moved in to kiss him. “Sideswipe,” she moved with him, forcing him to look at her. She switched to her internal comm. “No matter how skilled your brother is, it’s not his berth that I’ll be returning to. I don’t work like that.”
He turned a glare on her, still refusing to meet her lips. “So what? You going to kick me off my berth so you can interface with my brother?” His fingers clawed into the rubber mat that covered the berth. “Or are you going to make me lay here while I know he's jacking into and jacking off of you? Are you going to-” His arms suddenly wrapped around her, and he clutched her to his chest, squeezing her desperately. “Can't I have one thing that I don't have to share with him? He has his art; even I can't compete with it all the time. Can't I have you to myself?”
She shoved him away, optics burning in anger. “I'm not some object you can possess, Sideswipe. How many times am I going to have to say that?” Her doorwings twitched and she sat back down next to him, and smoothed her hand along his bare thigh. “I just want to see things from your perspective. Can't I have that chance? The chance all those other femmes are given, you're going to deny me?”
He didn't look at her, but his dental plates ground together and his fists clenched on the berth. He didn't have the chance to reply.
Sunstreaker stepped into the room, carrying a small tray of coolant cubes. He clenched his jaw as he glanced around the room, frustration eking out of his frame. He didn't say anything as he handed a cube to Prowl. Sideswipe looked intently at Prowl, almost glaring, but she recognized his contemplative expression. He took the coolant and downed it in one gulp. Sunny was right there with a second cube.
Sunny's abilities to predict his brother's needs amazed her. They knew each other so well, it seemed. Had she caused this discord by coming into their life? Her doorwings drooped as she contemplated how they both must have felt while she degraded the lifestyle they truthfully had no choice but to live. Would they live apart if they had a choice? Could they live apart? And if they couldn't, could she expect them to not find each other irresistible; knowing each other so well, feeling each other every day as they did. Could she blame them for not being able to understand the boundaries of a natural sibling relationship? Could she-
All processes froze as Sideswipe suddenly, and certainly unexpectedly, grabbed his brother's wrist and dragged him down. Their mouths met with a hard klink; lips scraping against each other with unprecipitated vigor. It didn't take long before Sunstreaker's ventilators started and he moaned against his brother's lips.
Prowl couldn't keep the disgust from clenching her hands, her optics from shuttering; vorns of habit bidding her to react in a way that she didn't want. Vorns of beliefs wouldn't simply disappear in one astrosecond, but she bid her hands to relax, and her optics to open.
The tray had fallen sometime while Prowl wasn't looking, she hadn't even heard it hit the floor, but the coolant spattered over Sunstreaker's legs in a fascinating pattern, spilling over his feet and onto the floor. His hands wandered over Sideswipe's shoulders and she flinched again, doorwings twitching involuntarily.
Sideswipe had been watching her and he narrowed his optics at her. “This is what you're asking for, Prowl. This is what we do. You can have me, by myself, but do you really want this?”
She watched them, watched Sunstreaker's lips trail down Sideswipe's jaw hinge to the lines of his throat. Sideswipe tilted his head back, optics darkening, lips parting to let out a husky groan. She couldn't tell if he was putting on a show for her, or was honestly reacting to Sunstreaker's attentions.
Sunstreaker stroked his fingers down Sideswipe's chest and holding area.
She moved closer, unable to tear her gaze away from the two mechs in front of her. Her ventilators working overtime to cool her heated systems. Sunstreaker still attended Sideswipe's neck, leaving her lover's mouth panting and alone. Sideswipe didn't seem to notice her approach, engrossed in the feeling of his brother's mouth on his neck, of his own hands on the golden plating
He sighed when one of her hands rested on his mag plate. She gained his attention, when she pressed her naked frame against his, sliding her plated knee between his thigh. She felt Sunstreaker sweep his sensors over her, heard the soft, possessive buzz of protest from his vocalizer.
She ignored him, instead focusing her gaze on Sideswipe's closed mouth. He stared back at her, uncertain, his gaze flicking down toward her naked frame, only to quickly look back up when he realized his error. She settled her mouth over his, enjoying the way his lips conformed to her own. She cupped his jaw in her hands as she leaned over him, pressing him down toward the berth.
He resisted, bracing his arms behind him. “Prowl, what are you doing?” He didn't, however, resist as she slipped her glossa into his mouth.
She moved in when she noticed Sunstreaker had pulled away, aware of his gaze on her doorwings. “Do I really need to answer that, Sideswipe?”
An uncertain touch, brushing across the edge of her doorwings. An unspoken query, not directed at her, not even transmitted on any tangible channel. Then Sunstreaker moved behind her, sure fingers unhooking her canopy, tossing it to the side with a clang, allowing him to stroke down the line of her back. His fingers delved into the visible gears that quietly whirred within her backside. She moaned at the vibrations of his fingers as they came into contact with the working machinery, as he caressed the exposed circuits and cable. He pressed up against her back, hands gripping her elbows while he pressed kisses on to her shoulders and neck.
The golden mech stroked his hands down her sides, fingertips brushing against her breast. 
She kissed down Sideswipe's neck, nipping gently; moaning as Sunstreaker continued his explorations down her holding area.
The golden twin leaned past Prowl, taking possession of the mouth that Prowl had freed. The soft whisper of his ventilators humming against her doorwings drove Prowl into a tactile frenzy. She groped at Sideswipe's legs, digging her fingers into his thighs, and the plating that covered his calves.
Sideswipe lifted a hand to stroke his brother's headvents, their lips squealing against each other. “This is really unfair of both of you!”
Prowl picked up the subtle buzz of a second channel; Sideswipe relaying the same message to his brother.
Sunstreaker spoke aloud, his vocalizer staticked and husky with desire. “If you make me stop again Sideswipe, I swear I'll pound you. I don't want your femme, except for the odd romp.” She met his cold gaze, his fingers tweaking a sensor on her thigh. “I'll pound her, too, if she tries to make this is anything more.”
Sideswipe turned his head to nuzzle Prowl's chevron. “Threatening Prowl doesn't exactly endear you to me, bro.”
“I'm not 'his femme,'” she growled at the same time.
Sunstreaker snorted. “Like I care. Just shut up and give me another kiss.”
Sunstreaker lingered in the kiss only for a moment, then he turned his attention to Prowl again. His hands traveled down her waist, caressing her silver thighs. He placed a kiss on her upper arm, his hands continuing their journey down her calf plating.
“We don't have to, Sideswipe.” Prowl swept her lips back up to his, letting her meet his gaze. She rubbed her fingers over his cheekguard. She pressed a tender kiss to his cheek, just under his optic. “Tell me, to stop and I'll walk away. I'll leave you two alone.”
Sunstreaker tugged at one of her leg plates, unlatching them and working them off her leg.
Sideswipe closed his optics, venting a soft sigh. He pulled her face down so their optics met. “Leave? Fraggit, Prowl, I don't want you to leave. Don't say things like that while you're doing this!” His fingers tightened on her shoulders. “Don't go. Stay.” He pressed a tender kiss to her lips, his glossa sliding along her lips with a delicious thrill.
“Are you two quite done arguing on private channels yet?” Sunstreaker suddenly snapped, plating dropped to the floor, and despite his harsh words, his fingers explored the wires of her calf tenderly. He nipped her thigh, attracting her gaze as he lay his vent against her knee. But it wasn't Prowl whom he looked at.
Sideswipe leaned his head against Prowl's fore, his gaze on his brother. “Yeah, we're done.”
A smile twitched on her lips. “It's nice to know that you care about your brother's happiness, Sunny.”
Sunstreaker looked up, expression serious as he dug his fingers into the gears buried under the wires. A sharp, pleasant, painful sensation that made Prowl throw her head back with a gasp of surprise. He pulled her legs out from under her, twisting her around so that she lay in Sideswipe's lap. “I do care about his happiness, Prowl,” he purred as he crawled up to kiss her on the mouth; his lips as warm and sensuous as she remembered them. “Otherwise I’d slag you for calling me that.” He didn't stay long, making his way back down to her legs, leaving a trail of kisses as he went.
Sideswipe caressed Prowl's cheek, and chin, running his fingers over her lips. His optics however stayed on the golden mech shaking the plating on her legs off. He leaned down, rubbing his lips over her chevron, his hand stroking down her neck and over her collar ridge. He murmured senseless words as he trailed kisses down her face and to her lips. He caught her lips, as Sunstreaker threw the other piece of plating to the floor.
The golden fingers probed along the back of her legs, his optics half shuttered as he fingered the twitching gears and ran his fingers along the wires and tubing in the back of her leg. He kissed her legs, running his glossa over the seams of her knees. He rubbed her feet against his chest, his optics dark and unfocused as he seemed to immerse himself in the feel of her legs against him, his hands on her calves.
Sunstreaker stroked her in all the right ways, his fingers finding every sensitive nook and cranny in the back of her legs. Oh Primus! Oh Primus, she never knew that touching that area... could feel... so good. She gasped, writhing in the twins' grasp and moisture coated her mouth.
Sideswipe pulled away suddenly, panting, fingers tightly gripping her chest. He resisted her efforts to pull him back down and resume the kiss. His dark optics, and the twitching hardware by her audio receiver showed the effect of her lubricated kiss.
She caressed his cheekguard, his chin, desperate to alleviate the feelings coursing through her circuits.
The plated legs under her back shifted and Sideswipe trembled as he licked traces of lubricant from his lips. Her name drifted from his vocalizer, drawing her to him like an inexorable force. She pulled herself up, wanting to taste those lips again as Sunstreaker continued to handle her legs like the finest art.
The golden mech grunted as she pushed her feet against his chest, leveraging her toward his brother.
Sideswipe leaned down, brushing his lips against her cheeks, “You want Sunstreaker, right now, not me, remember?” They stared at each other, the disapproval still evident in his frown.
She slid her hands around his neck, stroking him reassuringly as she leaned against his chestplate. “Sunny, is there a femme that's been able to resist your 'charms'?”
Sunstreaker paused in nuzzling against her thigh. “Keep calling me that and you'll be the first I start on and never finish.” He trailed kisses down her thigh. “No femme can resist me when I put out. I can't help it that I'm irresistible.”
She allowed a smile to twitch her lips as she shoved him with her bared foot. “Am I to be more than any of those other femmes, Sides?” She shut off her vocalizer on anymore words. She had no wish to dent Sideswipe's already scratched pride. Her doorwings wilted, sliding against his side. “Sideswipe, I love you.”
Sunstreaker nipped at the junction of waist and legs, the soft click of his dental plates on her seamless metal exterior drawing a gasp from her ventilators.
Sideswipe's optics softened, and Prowl wondered what had passed between the brothers. Had they been speaking this entire time?
“I love you, too, Prowl.”
She moved to kiss the naked mech, but Sideswipe wrapped his arms around her waist and hauled back. She squealed at the unexpected move, doorwings pressing against his sides. He held her to his torso, pressing kisses to her neck
A shudder racked her frame as Sunstreaker probed her with his glossa. She whimpered, twisting and turning as he caressed the edges of her receptive port with his rubbery glossa.
She wriggled in Sideswipe's arms, trying to reach her lover's lips. He buried his face in her shoulder, sliding his legs between her own and using his knees to spread them wider for his brother. His hardware prodded against her thigh, contrasting with the controlled front he displayed.
Sunstreaker kissed his way up her holding area, stroking the dips at the side of her engine with his glossa. Sideswipe's hands traveled ahead of his brother's lips, caressing ands soothing over her curves. Air washed over her shoulders and neck, the desperate intakes of a heated system. He paused at her breasts, molding their shape, fondling them. His black fingers swept over the sensor nodes on her breast, and she gasped, bucking at the wave of ecstasy that rushed through her systems.
The mechs grunted as she shoved against them, and Sideswipe repeated the gesture.
Lubricant burned in her mouth and she yearned for nothing more than to kiss one of them, to spread the sweet solution over their chassis. She grabbed at one of Sideswipe's hand, pulling it up to her lips.
Metal thunked onto the carpeted floor; Sunstreaker's chestplate.
He rubbed his bared frame against her waist and holding area, his engine purring delightfully between her thighs. He pulled himself up and kissed her on the lips, his optics darkening further as he slid a hand behind her head, delving into her mouth with his glossa. His frame felt wonderful against her naked form.
She squirmed under him, returning the kiss with no less fervor. Both of the mechs groaned, their grips tightening on her as she pressed against them, scraping across their exteriors, and Sideswipe's exposed shaft.
Sunstreaker's hands slid down to Sideswipe, even as he deepened the kiss with Prowl. Their glossa twining and sweeping into the other's mouths, her sweet smelling lubricant drove Sunstreaker into a frenzy; rubbing against her, his hands grabbing at Sideswipe underneath her.
Sideswipe groaned, thrusting against her thigh, hardware active and ready. “Sunny!”
Her gears ticked against his chest, and he squeezed the breasts he still gripped spasmodically.
“You're not ready,” Sunstreaker murmured against her lips.
She didn't need him to tell her that; programs still initialized on her HUD, and her mouth still burned from the lubricant. Sunstreaker's attentions turned to her neck, mouthing, biting and nipping while she ran her glossa over his vents; her hands all over his shoulders and back. She plucked at his hip plating, rubbing her thighs against his hips suggestively.
He continued down to her chest, licking at the slope of her breast. The lubricant he had picked up from her mouth burned against her chestplate, setting off the sensors with chemical resonance of the unmixed lubricant. Sideswipe released her breast to caress his brother's neck. Sunstreaker didn't move Sideswipe's fingers when they gripped her again. Rather he worked around the black fingers, pausing to nip at the joints and struts. The feel of the glossa sliding into the groove where Sideswipe's digit and her breast met, under the bent joints of his brother's fingers had Prowl crying out-- screaming as he rubbed the sensitive knob underneath one of those joints. She bucked against him, mouth gaping as he moved to the other breast. She panted, writhed, causing both mechs to groan and pant against her. Sunstreaker buried his face in valley of her breasts, his vents scraping against his brother's fingers.
“Sideswipe!” It was the closet to begging she would come. She reached behind her, grabbing at Sideswipe.
“I think she's ready, bro,” Sideswipe groaned, releasing her with one hand and pulling it away toward his head.
Sunstreaker grunted, but caught her lips again. He then pulled away, sitting up on his knees to look down at them as he worked the plating off his hips.
She didn't want to stop, didn't want him to stop. She twisted about, trying to find her lover's face, so that she might kiss him into the same frenzy she had worked her brother. She pressed her lips against Sideswipe's cheek seam, but he pulled away.
“No, Prowl. This is Sunny's chance with you,” he rubbed his cheekguard against against her nasal ridge, his normal grin distracted by his panting mouth. “But I'll be here with you the whole time, riding him while he's in you.”
She shuddered at the sultry purr in his voice, the eager pant of his vocalizer. She reached behind her head, stroking his audio horns as Sunstreaker threw his hip plates to the floor.
“So I can't kiss you?”
He laughed at her petulant whine. “No, you can't.” He hissed as she wriggled in disappointment. “You can't handle three overloads so close together.” His arms lid around her torso. “Slag, I can't handle three overloads too close together.” He tightened his grip as she tried to get up.
“Sideswipe, I need to sit up. Sunny needs to be lubri-”
“Nobody's putting their slagging mouth on my hardware!” Sunstreaker snapped suddenly. “That, Sides,” he squeezed a solution from a tube, “is why I don't bring femmes home. They want to put their moist little mouths on everything you own.”
Sideswipe bit into her neck, tweaking the sensor on her breast. He plugged his interface cable into the port under her headgear. He dug his fingers into her doorhinges.
Anything she might have retorted at Sunstreaker died with the activation of her interface programming. He integrated himself into her systems like he was made for them, brushing against her firewalls like a glass cat that's keen on the oil in your hand.
She gasped, arching her back as he ran his electronic fingers through her processor.
Her optics reset, flickering as he settled into her mind as easily as he settled into her recessed port.
Then she was looking at Sunstreaker....
...his twin...
and such affection filled her as she never thought possible...
...can I help but love him?...
What was Sideswipe doing?
...sharing my love... sharing the feeling of him joined to me... the only way I'm able...
She gasped as he stroked her breast, sharing the sensation with him, having it returned equally to her.
Sunstreaker settled over her, looking her over with that calculating gaze of his. His dark optics flickered, and he pressed his lips against her mouth, his glossa sliding around her mouth hungrily.
He broke away to kiss her chin, his hands braced on the bed as he thrust himself into her. Sideswipe bucked, his hands spasming on Prowl's waist. She shared the sensation of herself rocking over him as Sunstreaker pressed himself further in.
The cold lubricant made her whine, but she wrapped her legs around his waist; the gears of her calves pinging against his aft as she moved with him. She gripped his shoulders, unable to process clearly enough to do more than that.
She felt each of their movements like she wasn't even between them, or like she was Sideswipe returning Sunstreaker's invasion thrust for thrust. It wasn't her that Sunstreaker kissed, that Sideswipe pressed against with such need.
She wasn't there.
She had never felt so small in the universe.
Then Sideswipe played through her systems, activating sensor nodes and diagnostic programs; sending her into writhing fits, clinging to his brother (but it was Sideswipe clinging to the golden mech).
Tears blurred her vision, and her (maybe it was Sideswipe's) hand rose to brush them away, his words a gentle whisper of reassurances.
Sunstreaker jolted against her, the connection snapping into place. As suddenly as it was made, it disappeared and she cried out at an unexpected buzz from within her.
“What the- Sunny? What was-”
She struggled to push him away, but Sideswipe stroked her doorhinges, sending a pulse of data through their interface.
“It's okay, Prowl,” Sunstreaker murmured against her shoulder as he resumed his thrusting, “it's just a peripheral. I don't want it over so soon.” He moved his attentions back down to her breast, biting Sideswipe's fingers and nipping at her sensor nodes. Her fingers sang with the delight of his touch, sharing in the sensation of Sunstreaker's dental plates on Sideswipe's digits as surely as if it was on her own.
They wrapped her in the rocking cocoon of their affection for each other, Sideswipe's affection for her bleeding together with his love for Sunstreaker. Every time Sunstreaker connected, vocalizer surging with a grunt, his peripheral buzzed him loose.
The tip of Sideswipe's shaft rubbed against the hilt of his brother’s, and Prowl felt it like a peripheral to her own anatomy. The red twin gripped her hips hard enough to dent the curves, trying to meet each of his brother's thrusts.
“Sunny!” Sideswipe gasped. His status changed to yellow in her HUD over their connection.
Sunstreaker suddenly pulled out, and away, leaving her panting and confused. He disconnected a jack from his shaft, removing a peripheral motor attached to his hilt. Then he pounced on her again, his dark optics unfocused as he drove himself back into her, connecting hard and sudden.
Her systems redlined, following Sideswipe into overload as Sunstreaker's energy poured through her relays. She wailed, her voice mingling with the two mech's; firewalls redirecting the spark energy into storage cells, and then over the interface.
They lay tangled together as their systems rebooted, engines chugging uncertainly.
Sunstreaker pulled away first, disengaging himself from her and rolling away. His intakes worked hard to cool his heated systems off, his dim optics watching his brother and Prowl.
Sideswipe carefully rolled Prowl onto her side, minding that the doorwing bent the right way. He didn't relent his grip on her hips, kissing the rods in her back as she shifted against him.
She wondered if they really needed anyone else, when they had each other.
...sparked loving him… fell in love with you…need you…
Shaking fingers pulled the interface cable free of Prowl's headgear.
“Sunny,” the golden mech's optics narrowed, “I'm sorry I didn't stop to listen to you at first.” Her doorwings twitched. “Nothing should get between you two-”
“You can. Unless you fragging call me slagging Sunny again.”
She looked at him a little warily as he slid closer, putting an arm around her waist, and hence over Sideswipe's. His face settled close to hers, almost uncomfortably close.
“You... You can get between us.” He smirked. “Besides, I want a go at the bottom next time.” He kissed her lips, gently without any tenderness, before leaning his head against her chest, optics shuttered.
“He likes you, Prowl,” Sideswipe pressed a kiss to her headgear, his hands soothing over her torso. “Though you'll go to the Pit and back before you hear it from him.” He reached a hand into her doorhinge, absently tweaking the joints. “We haven't done this in a while. A long while. Thank you. It means a lot to me.”
Drained from both the data and power overload, she couldn’t do more than pat his hand before curling into the warmth of the two mechs around her.
Maybe she wasn't so unnecessary.
How many femmes would be willing to accept their relationship, as morally illogical, and at the same time understandably logical, as it was?
Prowl thought she should be proud that she was one of those few.
