Justin Sider, alone and hard, strokes his engorged cock, the anticipation of his lover's return fueling his desire. He knows she's with another man, and the thought makes his balls tighten. His hand moves faster, the sound of skin slapping against skin filling the room. His breath comes in ragged gasps as he feels the familiar tingle in his spine. With a final, powerful stroke, he comes, his cum erupting from his pulsing cock, coating his hand and stomach.
