Bathe... my wife!!!

My wife and I have been married for a while but I still haven't met her younger sister Mayuki. This time Mayuki had a day off so she came to our house to hang out, it was also the first time I met her. From the first glance, I was mesmerized by her beautiful F-Cup breasts.

And it seemed like she wasn't even wearing a bra! Her nipples seemed to want to escape from the tight shirt, the top of her breasts clearly visible in front of me thanks to the off-shoulder top she was wearing! Mayuki's seductive actions quickly made my cock hard. And when I couldn't resist anymore, we continued to sneakily fuck even when my wife was nearby! I am truly excited by this illicit affair. And I want to repeat those exhilarating experiences with her. Fucking each other when visiting my in-laws, even fucking her right next to my sleeping wife!!!
