First time I visited my girlfriend's house, her parents had moved to Tokyo, so she was living with her sister. When I arrived, a beautiful woman with huge breasts appeared before my eyes. And upon closer inspection, I noticed that she wasn't wearing a bra! It turns out she was my girlfriend's sister. From the moment I saw her, I was captivated by her seductive charm. When my girlfriend went shopping, her sister reappeared in front of me in a very provocative outfit. No man would resist touching those incredibly beautiful and huge breasts! I couldn't control myself and reached out to squeeze her breasts, and she responded to my actions. And our improper relationship began from there. I indulged in fondling her breasts, fucking her pussy, even though my girlfriend was right next to us...
