Bound and helpless, the sub's body tenses as the first domme slides the cold, slick strap-on into his ass. She pushes deep, smirking at his gasp of pain and pleasure. The second domme joins in, her hands roaming over the sub's body, pinching his nipples and stroking his growing erection. They switch places, the second domme taking over the brutal pegging, while the first domme feeds the sub her fingers, covered in his own saliva, simulating a bisexual threesome.
