A straight guy, hidden away in his room, decides to put on a show for the camera. He's dressed in casual jeans, the fabric straining against his growing bulge. With a mischievous grin, he starts to stroke his length through the denim, feeling the rough material against his hard cock. His movements become more insistent, the outline of his dick clear as he grinds against his palm. The sight of his jeans growing darker with pre-cum turns him on even more, and he finally unzips, revealing his throbbing member. He pumps furiously, his breath coming in short gasps, before letting out a low groan and coating his jeans with his hot cum.
