During the exam, after a month of abstinence, I got my friend's mother pregnant. (Miyagami Yuika DLDSS-540)

With only a few months left before the exam, Ken devised a secret strategy to focus on his studies—abstinence. However, at the home of his friend Makoto, with whom he often studied, a temptation awaited him, threatening to thwart this plan. That temptation was Makoto's mother, Yuika. Her mature adult charm captivated Ken. Then, on the day after a month of abstinence, the barrier was finally broken. Yuika's underwear was found in the changing room. And, coincidentally, Yuika emerged from the shower, and then that thing happened (the breakdown of abstinence).
