Severus curled his spine, panting, angling to get the friction and pressure to his prostate, even as the tip of his cock rubbed against Al's belly. He wrapped his arms around Al's shoulders and moved with him, even as Al moved within him. The water rocked them both, waves rising, lapping at their bodies.
Panting, wild eyed, Severus stared down at Al, drinking in the sight of him, his familiar, beloved face bright with the flush of arousal, his eyes so wide, their pupils blown, stunned with bliss.
As his body shuddered on the brink of climax, close... so close the last distance between them closed, and his mind fell into the mind behind arousal-darkened green eyes.
