Sei waking up in the middle of the night to realize he's being straddled. Aoba leaning down to nuzzle against his shoulder, his neck, pressing a few wet kisses and whispering his name in such a needy, sultry manner... Sei's confused expression darkens and he grips Aoba by his shoulders, shoving him off and onto the mattress. Aoba just lies there a bit, blinking slowly, until he starts chuckling lightly. "You're so rough, onii-chan~" Sei grabs his pillow wordlessly and moves to the living room.
[LOUD MONSTER TRUCK NOISES]
He’d probably do this every night with different methods to see if he can finally break him, though Sei has a surprisingly high amount of restraint.
Even then though, Sly can still sometimes hear the muffled gasps coming from the bathroom in the middle of the night. So it ain’t that damn high.
Now if only he can hear those sounds a little closer.
The real kicker is that it becomes really obvious to Sei what he’s trying to do, but Sei wants to be a good brother and refuses to let some thirsty-ass personality of Aoba’s get the best of him, even when he wantonly begs for Sei to completely mess him up until he couldn’t stand anymore, or all the things he imagines him doing to his body that they could make a reality if he just gives it up and play with him.
Even when every corner of Sei’s mind screams at him to take ‘Aoba’ then and there, he can’t. Not if it isn’t what his Aoba wants.
As he would lay there on the couch that night coming to terms with his own thoughts, he hears a chuckle above him.
"I’m his desire. I just go for what he really wants, you know.”
Sei turns away from him.
"Go back to bed before I do something we both regret."
I've noticed that you tag your posts including Sei as 'My husband' and I'm going to have to ask you to please stop. I identify as Sei and I did not consent to this and it does make me feel rather uncomfortable.
Sei using two of those hands to pin Aoba down, gripping his wrists on either side of him while his free hands are able to leisurely explore his lithe, squirming body, touches skimming under the hem of shirt before snaking under and stroking at his soft skin.
OHOHOHOHOHOHOHOHO SOMEONE’S ALREADY IN MY HEAD~
