Hearing Will groan against him was all it took. Tuck felt himself tumble over the edge into orgasm so quickly he couldn't even warn Will, which would have been kind. Instead he sort of shouted nonsense, his head falling back so quickly he hit the shower wall hard. Pain mingled with pleasure, which only made him moan, his hips sort of stuttering as his climax burned down to embers.
Then he went limp, sliding down the shower wall to the floor, where he sat there, curled up, panting, gazing at Will with adoring eyes.
