The extreme frustration of being forced into a long sexless life had even robbed Yoko of her ability to think clearly. Ever since she pushed down her son, whose penis had grown to adult size, and began a forbidden relationship with him, Yoko has been revealing her female nature, begging for her son's cock with extremely vulgar words and actions. She doesn't care that her son is confused by her mother's rampage, or that her husband is right next to her when he gets home. He is extremely sexually powerful, and Yoko is obsessed with his son's cock, which keeps getting hard again and again. Today, she attacks her son with a lustful expression on her face, forcing him to cum inside her repeatedly until she is at the limit of her physical strength.
