In my head Blaine’s giving Kurt a vibrating cock ring, and he pulls him into the boys toilets and fists his hand into Kurt’s jacket, smashing their mouths together so hard they crash against the wall and into a stall tripping over each others feet.
And then Blaine puts it on him and winks and it’s the kind that has a remote so Blaine can turn it on and control the vibrations from across the room and at first he doesn’t do anything and Kurt is half hard and tingling and nervous and he’s flushed but Blaine just looks at him and smiles and kisses his cheek
Then they’re in the library, or working on group work in class and Kurt has to keep quiet and the vibrations are muffled by low speaking and his hand is gripping his pen until the plastic cracks and he’s sweating and blushing and his toes are curling inside his shoes and he’s building up and up and Blaine’s just watching him from across the room, holding his gaze with eyes all deep and dark
But he doesn’t let him come and he switches it off and Kurt has to bite back a whimper and he’s thrusting at the air and desperate and people are giving him strange looks and he’s shaking until he can barely think straight
And Blaine brings him to the brink over and over, letting Kurt teeter and muffle his moans into the back of his hand, watching his eyes flutter closed across the room and his fingers dig deep into the chair or table edge
They go home and Kurt’s desperate and kissing Blaine hard and wet and messy and rutting against him and he’s so close and so fucking hard and he’s been so ready all day, but Blaine pulls away and kisses his forehead and goes to the door saying one thing
“don’t touch yourself.”
And Kurt holds off. Barely.
He’s burning and aching and frustrated and tugging at his hair and scraping his fingernails over his nipples and writhing, sweaty and dissatisfied in his own bed sheets but he won’t touch himself, he just won’t
Blaine knows the next morning when they meet early at the lockers, when Kurt’s wild eyed and his hair is messy and his eyes dark, and he drags Blaine into the auditorium and it’s dark and echoing and the doors don’t really lock, and they can hear the crowds moving past them but neither of them care because Blaine has spent the night tossing and turning too, and rubbing his palm over his cock through his pajama pants but going no further
They collapse onto the floor and rut hard against each other, grinding into each other’s hands over their clothes and they’ve been having sex for a while now and it seems like it’s been ages since it was just this, just want and lust and each other, and that burning ache that seemed to flame with the need to touch each other
They skip the rest of the day, and Blaine nearly crashes three times on the way to his house when Kurt’s hand rubs against his erection, and when they make it to his house it’s just quicker to scramble onto the back seats than try and get inside
Besides, they’ve got all day.
