Kurt could feel his muscles tensing, jumping, his body fighting for release as he stayed focused on the touch of Blaine's hand on his cock, how he felt thrusting inside of him. He didn't want it to end, not when everything was feeling so incredible, but he knew it was going to. Of course it was something they were going to do over and over, but that moment, right then, he didn't want it to go.
And then Blaine was telling him to come and he felt the shift in how he was pushing into him, and his eyes opened to look up at him just moments before he choked back a moan, his orgasm hitting him hard.
