His girlfriend's gorgeous, big-titted trans sister has a large cock and a toned body from working out. When her unguarded training clothes reveal her hard bulge, he cannot look away and impulsively slides straight into her ass. She cums immediately, her anus spasming and clenching tightly around his cock. The unfamiliar grip leaves him hard even after orgasm, and she milks load after load from his balls with her ass. By the end, he is completely hooked on a pleasure his girlfriend's pussy could never give him. Every scene includes ejaculation from her cock.
