A stepmother fed on by her stepson's penis... 2. Rumi Kodama CESD-284

Rumi Kodama gets along well with her husband, but while he sleeps at night, her stepson treats her like a female dog and trains her. She is forced to stimulate her anus and then a vibrator is inserted to bring her to orgasm. During meals, she is secretly flirted with a remote-controlled vibrator. In the end, she becomes her stepson's sex pet!
