YAL-090 The son's twisted fetish of only playing with me when his father is around

Yuka, who finds happiness in her ordinary life as a mother, is preparing dinner while waiting for her husband to return home. Her son appears and starts molesting her body. He sucks on her breasts, flips up her skirt, and inserts his fingers into her vagina, enjoying the sensation. Yuka's expression gradually changes from that of a mother to a female one, unconsciously taking her son's penis in her mouth and moving her tongue inside. She is made to deepthroat, receiving semen in her mouth. Her son plots to rape her in front of his father today.
