[PRED-779] During a slump in my relationship with my wife, I was seduced by Tsumugi (my sister-in-law) and ended up cumming inside her over and over again... Tsumugi Akari (Censored)

While his wife was away on a trip, he had a forbidden secret rendezvous with his sister-in-law Tsumugi... As their relationship cooled, he could no longer resist her temptations... "You're probably having an affair while you're away..." But Tsumugi's sweet whispers blew away his reason, so much so that he thought it was wrong... Day, evening, night, and the next morning, he had intense sex with Tsumugi, who was much more beautiful and erotic than his wife, and came inside her over and over again. It was the best moment, as they continued to desire each other. He wanted to stay connected in mind and body forever. It felt so good that his head melted from the sense of guilt and euphoria...
