Slip and Slide

Miss Riley has her slave bound and gagged for sexual torment. Riley unlocks her slave from chastity and rests her pussy over his sensitive penis. Miss Riley wants to cum, but she will not allow her slave the pleasure of being inside her pussy. She straddles her slave and grinds herself back and forth along his erect penis. The more she rubs his cock in-between her lips the more aroused, wet slippery she becomes. Riley enjoys the feeling of his slippery throbbing cock rubbing against her clit. He tries to resist having an orgasm while she is enjoying herself but the thought of resisting just brings him closer to the edge. Riley cums while grinding her pussy against his cock... he cant hold it any longer..... he cums all over himself without any penetration.
