Oshiego no Kyonyuu Seiso Haha ga Akogareno Moto Dokyuseidattanode Oyako NTR-chu Dashi Haramase suru Hanashi | 教え子の巨乳清楚母が憧れの元同級生だったので母娘NTR中出し孕ませする話

The protagonist is the swimming club's advisor.

On the day of their open practice, he learns that the mother of Natsune, his favorite female member whom he especially favors, is Chihiro, a beautiful woman he admired and used as masturbation material during his student days.

He wants to make Chihiro, who has matured and become even more sexually attractive than in her student days, his own. Unable to suppress such desires, the protagonist uses his authority as an advisor to demand a one-night stand from Chihiro, on the condition of recommending her daughter.

Chihiro, torn between her love for her husband and her concern for her daughter's future, accepts the deal. However, having only known her unenthusiastic husband, she cannot withstand the protagonist's inexhaustible lust and is completely overwhelmed.

"If you don't satisfy me, the deal is off."

The protagonist appeals to Chihiro in this way, pressing her for further relations. He repeatedly engraves pleasure into Chihiro, who had never known a real man!

Eventually, Chihiro falls into the ideal role of a masochistic sex slave, prioritizing serving and fawning over the protagonist over her love for her husband and daughter.
