Kurt swallowed hard as his body tensed at the feeling of Blaine humming against him. It was like some sort of not so secret weapon he had in his arsenal, because that always felt so amazing -- be it when he was fucking his tongue into him like he was then or when he had his mouth around his cock, it was always the same. It was like an instant shove toward release, and it was just intensified by the rub of his thumb against the slit of his cock and he bit down on his lip hard as he came, a sob choked back in his throat.
It felt like his entire body was thrumming, pulsating, as he laid there and tried to remember just how to breathe -- and it didn't help that he knew they weren't done. His fingers loosened their hold in Blaine's hair, but not his own, and he trembled lightly as he managed to open his eyes and look down at him.
