The straight twink's heart races as he feels his cock, slick with lube, pressing against his partner's virgin hole. With a push, he's inside, the tightness enveloping him. He starts to move, slowly at first, then with more confidence as his partner's moans urge him on. The room fills with the sound of their flesh slapping together, the straight boy's hips pistoning as he fucks his first man, his cock disappearing completely into the tight ass before him.
