HEHE YOU'RE SO RIGHT ANON! I love touch starved Rui so much... Normally I imagine Rui in a more dominant position because I'm 2000's yaoipilled, but Rui being overwhelmed by the pure sensations Tsukasa gives him is also very very good. I think a lot about how lonely he was in middle school. "Sad wet cat" as they say, but I can't stress how fitting it is for him. After being shown the tiniest ounce of kindness and warmth he latches on to it. Having someone tell him that he's wanted, needed, is something he's been seeking since he was a kid, so of course when Tsukasa comes to ask him to be his director on the rooftop—a very notable place in regards to how he spent middle school—he can't help but feel the slightest bit of hope that things could change for the better.

And they do. The more time he spends with Tsukasa and the rest of WxS, the more he starts to finally feel like he belongs somewhere. He's not used to the hi-fives or Emu's tackle hugs, or even the friendly pat on the shoulder Tsukasa does when he comes over to greet him, but slowly they become a normal part of his life. He can finally be himself around people who care about him, being able to joke around and tease and mess around with Tsukasa without him giving him a look of fear and estrangement.

When they finally get together he's basically in uncharted waters. Romance has always been so far off his radar. He'd already accepted that he'd likely be alone for the rest of his life, so the fact that his feelings were actually reciprocated is enough to send him over the moon. They share their intimacy with stolen kisses on the rooftop and hands held under the table, and not even his normal devil may care catlike demeanor can mask how utterly happy he is just being able to bask in his star's presence. He doesn't dare ask for more, scared of moving too fast and making Tsukasa uncomfortable, despite being a healthy teenage boy who dreams a little too often about his boyfriend.

Imagine Rui's surprise when Tsukasa asks to sleep over at his place after practice one day. It's not an uncommon occurrence by far, but there's something about Tsukasa's expression, almost as if he's...nervous? In truth he's tired of waiting for Rui's slow turtle-like advance and resolved to take matters into his own hands. It had been months since they shared their first kiss, and he was sure that by now Rui would have made his move considering how he normally does whatever he wants to him, but despite all the little touches they shared Rui never initiated anything further. Tsukasa was quite frankly tired of fantasizing about what if would feel like to have Rui's dick in him, he wanted the real thing.

Tsukasa had already done all the research, hidden his "supplies" at the bottom of his bag, but, well, it was a little embarrassing even for him to just straightforwardly ask Rui to fuck him. He'd already made up his mind though, and when it was time to sleep they had a bit of a make out session on Rui's bed. Tsukasa decides to go a little further, deepening the kiss with his tongue and slipping his hands under Rui's pajamas. Up until now Tsukasa wasn't entirely sure if Rui was interested, and if he wasn't then it wouldn't be too late to stop and just go to bed. That is, until he hears Rui gasp into his mouth as his hands met the skin of his lean torso. He pulls back to see Rui's pupils blown, a light blush dotting his cheeks, and when he looks down he sees Rui's massive bulge strain the thin fabric of his pajama bottoms. He can't help but let his jaw drop. The bulge itself was almost the same size as Tsukasa's at full mast.

Needless to say, something snaps in Tsukasa's brain, and it doesn't take long for him to rip Rui's pants off and finally have his treat, despite Rui's stuttered attempts at getting him to slow down. He starts with a blowjob, struggling to take even half of Rui's length down his throat, but the sounds Rui lets out make it worth it. He's hiccupping and trying his best not to make a sound, only broken syllables of Tsukasa's name and wait, too much, I'm close. It doesn't take very much at all before he comes down Tsukasa's throat, apologies on his lips for the abruptness and lack of warning. Tsukasa doesn't mind though, swallowing the majority of it down as his eyes take in Rui's panicked and flushed expression. Completely different from his usual confident and teasing attitude. It only eggs him on, and to his delight Rui's dick is still hard (Who could blame him, Tsukasa still has Rui's come dripping down his chin).

When Tsukasa finally seats himself on Rui's cock, feeling the euphoric stretch, he lets out a long held breath, but over that he hears a long keening groan escape Rui's lips. Rui covers his mouth, embarrassed, but it only emboldens Tsukasa as he starts lifting himself and sinking down. Tsukasa tries to restrain his own moans just so he can hear the sounds that Rui makes. It's such a rarity to see his director fall apart like this, he wants to savor it and remember it forever. As he picks up the pace he can feel Rui's hands grip his waist, helping him lift higher and sink deeper. It seemed he'd given up on holding himself back, and the bedroom was full of both of their pants, gasps, and moans. And when they come together, groaning loudly into each other's mouths in a heated kiss, it's loud enough that Nene can hear next door.

Years down the line, I think Rui would become accustomed to physical affection, and while he still groans and grunts during sex, it wouldn't be like it was in the beginning. He still doesn't shut up though, he'll bring his teasing nature into the bedroom and whisper dirty talk into Tsukasa's ear nonstop. "Tsukasa-kun's hole is so tight, like it was our first night together." Tsukasa would bring up how he misses virgin Rui and how blushy and cute he was, but Rui would simply respond that he wasn't mentally prepared for Tsukasa acting all slutty and thirsty for his cock (me neither Rui, me neither).
