My girlfriend ordered me to abstain from sex until the very end, and I reached my limit, becoming addicted to having sex with her mother, Yuka. (Yuka Mizuno ROE-184)

Lately, I've been living a life of abstinence because of my girlfriend's instructions. So, I proposed a hot spring trip, and unexpectedly, her mother, Yuka, would also be coming along. Although I kept pursuing her during the trip, we ended up arguing. So, I went to the hot spring alone, only to find Yuka already bathing there—and it was a mixed bath! Attracted by her beautiful body, I completely forgot about my abstinence and just grabbed her like a madwoman.
