Karasuma Madoka is a beautiful model who is approaching her fifties and still has a beautiful face. To earn money for her stepson's study abroad, she accepts an invitation from a shady photographer to do a high-priced photo shoot, but in order to become famous, she is forced to engage in sexual favors and lewdly sucks the man's penis with her mouth and pussy. When her stepson finds out about his mother's job, he becomes enraged and pushes Madoka down, devouring her ripe body in a forbidden pleasure. Madoka is violated by her beloved son and accepts everything, climaxing lustfully with a thick creampie.
