For Yasu's birthday this year! For this prompt: Subaru wonders why Shota doesn't wear skirts anymore and gives him one (I prefer to think it's mini :D) as a birtday present. He's taken by surprise when Yasu tells him that what he really wants for birthday is to see Subaru wear his own present.
Yasu blinks down at the open box in his lap. He picks up the item from inside and examines it, trying to think of an appropriate response.
"You remembered my size," he says eventually, smiling weakly.
Subaru looks back at him seriously. "Good, I'm glad it'll still fit you," he says, deadpan. Yasu thinks he's looking at him rather expectantly.
"I thought you didn't like me wearing skirts," he says, trying to stop the smirk spreading across his face. "You said you missed when I was boyish. You said I'd gone too much like a girl and you didn't understand it!" He quite likes the mildly accusing tone that's crept into his voice - a plan is starting to form in his mind.
Subaru shifts, frowning. "I like it when you're - showing your girl side," he says a little defensively. "And I like it when you're a boy too! But... I like a bit of both," he goes on, sounding more lascivious now, but Yasu cuts him off.
"And you think I've gone too far the other way, so you thought you'd drop a subtle hint?" Yasu holds up the denim miniskirt at arms length, peering at Subaru over the top of it, eyebrows raised.
Subaru folds his arms. "I just thought it might be fun," he mumbles. "Spice things up a bit."
Yasu bites his lip, trying not to giggle. It's true, things between him and Subaru haven't quite been as... passionate lately and it's actually quite sweet that Subaru wants to inject a little excitement. In his own unique way. It's already been quite fun, but Yasu can think of another way of having even more fun.
"You know who else hasn't been wearing many skirts recently," he says, allowing the grin to take over his face now.
Subaru's eyes widen and his mouth opens comically. "Wait, wait, wait! That was NOT the idea..."
Yasu fixes him with a look that he hopes is promising, more than threatening. "But it's my birthday, and it's my present," he says, dropping his voice lower. "Shouldn't I get to do what I want? That would definitely spice something up."
Subaru looks torn. Yasu can see him weighing up the difficult question of whether to be firm and risk upsetting Yasu on his birthday and not getting any kind of sex at all, or just giving in and seeing where it takes them.
To Subaru's credit, it doesn't take him very long to decide. He sighs and starts to unbutton his shorts right there, letting them fall to his ankles and stepping out of them. He grabs the skirt and slides it up over his hips, trying his very best to look put upon and hard-done-by, but that doesn't last long when Yasu pulls him onto his lap and proceeds to show him that it may have been a while, but he hasn't forgotten just how spicy Subaru likes it.
