"I'll play with you for your behalf." My stepmother discovered that I was a sex industry professional who specializes in nipples. My nipples were tortured so hard that I went crazy, and ejaculated all the time until I ran out of sperm.

Maki, who lives with her daughter and her husband, is originally a serious person and only knew about normal sex. But one day, he finds out that his daughter and sexless son-in-law Tetsuya had secretly called a delivery health service to play with nipples... At this point, she couldn't contain the ache that was rising from deep inside her body and stimulated his nipples, saying, "To help her get along well." Unable to contain her excitement as Tetsuya responds in a funny way, twitching and in a funny way, Maki hides her daughter's eyes and bullies her nipples without her help.
