Gaius threw his head back, clinging to Sirius' shoulders as his lover claimed his body, filling him with hard heat in one long, fluid motion. A low, breathless moan of pleasure escaped him, and he fought down the urge to buck his hips and quicken the joining. This was perfection, and ease of their bodies becoming one, the sensation Sirius over and in him, filling all ov his senses. His fingers tightened on Sirius' skin, little shivers of pleasure wracking his body.
"Perfect, love. So perfect," he murmured, staring up at Sirius with eyes gone wide and dark with hunger. "You're magic all by yourself. Now take your pleasure in me - let me feel how desperate I make you."
