In a dimly lit room, a straight man, curious and willing, presents his bare ass to an unseen partner. A wet tongue laps at his hole, making him squirm, before a thick finger pushes inside, stretching him open. His cock leaks pre-cum as his ass is lubed up, ready for penetration. A large, hard cock presses against his rosebud, and with a deep breath, he relaxes, feeling the head slip in. His ass is filled, the sensation intense and kinky. As he's fucked hard, he jerks his cock, his body tensing, and with a final, deep thrust, he cums, his straight boy fantasy a reality.
