CETD-252 Sex Slave Training Corporation 4: A Mother’s Descent into Depravity, Forced to Crave Her Own Son’s Cock, Tied Cowgirl, Onani, Friend, Marriage

After losing her husband and raising her son alone, Oomura Shiho falls into despair and self-destruction. She is recruited by a human trafficking organization that specializes in turning women into sexual slaves. As she's delivered among other sex slaves, she discovers her beloved son among the buyers and desperately tries to escape—but is caught by a company employee. For the cutter, this is the ultimate reward: injected with irrational arousal, Shiho is made to greedily suck her own son's cock. Bound and restrained, with her nose pinned and body violated, Shiho is degraded through anal stretching and painful nipple play. Under harsh physical discipline, she is trained into obedient sex slavery and eventually shipped overseas.
