My girlfriend, who had been celibate for a month, and I indulged in extramarital sex during the two days she was away from home. (SSIS-367)

I started living under the same roof with my ex-girlfriend "Yukino," who was a colleague at the company, and my friend "Minami." However, my girlfriend, having exhausted her patience with me, a freelancer who hadn't managed to turn my life around, turned her attention to other men. So I decided to turn my attention to Minami, whom I secretly liked. However, "If I really like her... I have to endure it for a month before I go to Yukino for training." So, to prove my feelings, we began a period of abstinence... and in the moments when my girlfriend wasn't around, our sexual desires erupted, and Minami and I, like wild beasts, greedily indulged in a forbidden love-hate drama.
