Her ass, big and inviting, fills his thoughts. His cock, once soft, now tents his pants. He unzips, letting it spring free. It's thick, veiny, and hard as he grips it tightly. His movements are slow, deliberate, each stroke pushing him closer to the edge. His desire for her consumes him, and with a final, deep groan, he cums, his hot, sticky seed coating his hand and the image of her ass in his mind.
