As a birthday present, the incestuous mother offers the childhood friend to her son! The son molests the childhood friend's body, ignoring her resistance as he tortures her nipples, chokes her, performs fellatio, manual stimulation, and cunnilingus! Despite her reluctance, the childhood friend feels pleasure from this present, causing the son to become highly excited! Like playing with a toy, he rapes and ejaculates inside the childhood friend over and over again!!
