Two strangers, a curious couple, meet in a dimly lit BDSM dungeon, eyes locking on the submissive virgin between them. The woman, a dominant bisexual, smirks, "Tonight, your ass gets a cock." She orders the man to strip and kneel, presenting his virgin hole. She teases him, running a gloved finger along his crack, while the other woman watches, licking her lips. The submissive sucks the dominant's strap-on, gagging on its length, as she begins to stretch his ass with lubed fingers. The second woman joins, kissing the submissive, her hand replacing the dominant's on the strap-on. They take turns face-fucking him, his ass clenching, ready for the real thing.
