Creampie Baby-Making Diary with Sister-in-Law Aya

Synopsis

Keisuke has harbored feelings for his sister-in-law Aya for some time. One day, while his older brother is drunk, Keisuke overhears him discussing fertility treatment issues.

Keisuke had assumed his brother and Aya didn’t want children, but apparently they’ve already visited a hospital for testing.

With his brother passed out drunk and Aya cleaning up after dinner, Keisuke finds himself captivated by her voluptuous figure. His brother’s troubled words about “trying hard but…” keep echoing in his mind. In a drunken haze, Keisuke gives in to temptation and takes Aya right there in the kitchen.

The next day, sober and wracked with guilt over his forceful actions, Keisuke regrets everything. He can never casually visit his brother’s house again…

But when he arrives home, Aya is inexplicably waiting for him inside.

With a serious expression, she corners the bewildered Keisuke and pleads: “Keisuke… please… let’s make a baby together!”

According to the test results, neither Aya nor his brother has any fertility issues. The doctor suggested it might be a compatibility problem.

With no solution in sight, Aya turns to Keisuke for help. Despite knowing it’s wrong, Keisuke finds himself torn between guilt toward his brother and his own desires for Aya.

Thus begins their forbidden secret relationship…
