For for-science-john (I am soooooo sorry if you’re not into rimming, but here ya go)
Sometimes when John wakes up after Sherlock he’ll hear the shower running and he’ll roll out of bed, go into the bathroom, pushing off his pants along the way, and slip into the warm shower behind him, his arms immediately going around Sherlock’s waist from behind. Sherlock hums and leans back against him, and John presses kisses along his shoulders, his hair getting wet from the spray of water beating down on them both. He licks the water from the notches in Sherlock’s spine, working his way lower and lower until he’s on his knees, his hands smoothing up and down Sherlock’s thighs, and sometimes Sherlock turns and John sucks his cock into his mouth, but other times he tells Sherlock to lean forward, and Sherlock braces himself against the wall, already shivering with need, and John parts those cheeks and presses his tongue flat to Sherlock’s hole, licking it in one long, wet stripe, and then teasing it with the tip of his tongue, making Sherlock moan his name. One of those hands come back behind himself to press against John’s head, and he pushes his arse back against John’s mouth, and John licks all around that tight little hole, tensing it and pressing it inside as far as he can, and Sherlock whines, biting into his hand hard, and when John reaches around to stroke Sherlock’s cock the detective comes, hard, that little muscle fluttering around John’s tongue as it tenses. Afterwards, John stands back up, smirking, and Sherlock turns around, leaning against him weakly for support while he strokes John cock until John comes.
