A boyfriend's world is rocked when he discovers his girlfriend's secret. As they make out, she guides his hand to her crotch, and he feels the unmistakable hardness of a shemale cock. His curiosity piqued, he explores her body, his hands caressing her curves and the substantial length between her legs. She pushes him onto the bed, her massive erection tenting her shorts. She strips, revealing her hung, throbbing member, and he tentatively takes it into his mouth, his tongue tasting her salty pre-cum. She grinds against his face, then mounts him, her tight ass engulfing his cock as she rides him, her dick slapping against his stomach, leaving trails of pre-cum that he eagerly licks up.
