A straight guy finds himself craving for a guy's buttocks. He's not sure why, but he can't resist the urge to touch, to feel, to explore. He's not gay, but the sight of a male's backside is driving him wild with desire. He's a curious straight man, but his cravings are pushing him towards the world of gay sex. He finds a willing partner, a guy with a big cock and a tight ass. They start with frot, the friction of their bodies creating a heat that's almost too much to handle. Then, they move to missionary, the big dick plunging into the tight hole, stretching it, filling it, making the straight man moan with pleasure. The climax is explosive, a hot load of cum shooting out, marking the end of this strange, yet satisfying, encounter.
