After taking off his clothes, his erection was discovered by his forthright and loyal mother. If he tries to flirt with her, he'll become a woman, like Kaori-chan, and have sex with Yuri Kudo (HSODA-092).

Lily, a strong-willed, rude, foul-mouthed, and outspoken mother, has been estranged from her timid husband for a long time due to frequent business trips. Although she constantly clashes with her rebellious son, one night, even a simple teasing touch, like exposing her breasts, becomes noticeable to him. He starts masturbating in front of her, and finally, unable to resist, he comes to her bedroom and semi-forcefully removes her pajamas! Even when she tells her son, who has started giving her oral sex, no, her vagina still gets wet, and Lily grows increasingly timid. She is then forcibly penetrated and even has intercourse, experiencing multiple orgasms! From the next day onward, because her son discovers her liking for being forced, they engage in frenzied sex in the entryway, living room, kitchen, bathroom… all to avoid being discovered by her father! The mother and son are unable to stop indulging in unprotected sex!
