IPX-690 Having an affair with my boyfriend's sister

I am a fan of Momo Sakura, a beautiful and famous swimsuit idol. I also often masturbate using her pictures. My girlfriend Risa found me looking at a pretty girl with big breasts, so she forced me to take her to the movies. After watching, Risa invited me to her house to play, and I could also spend the night there because her dad was away. Great. If I could spend the night at my girlfriend's house, I would definitely get to fuck her! But as soon as I got to heaven, her next sentence pulled me back to reality. Her older sister was at home. It turned out that she wasn't an only child, and with an older sister at home, how could I get anything done? As soon as I got home, I was about to go inside when Risa told me to wait outside. Hearing my girlfriend's voice coming down, it seemed like her older sister usually didn't dress properly when she was at home. When I walked to the stairs, I saw a pair of see-through pink lace panties thrown on the steps! My girlfriend quickly hid it, thinking it was hers, so I didn't think much of it. While waiting for my girlfriend to make the cake, her sister appeared. And when I saw her face, I was so surprised that I fell to the ground. My girlfriend's sister was Momo Sakura. My idol. She was even more beautiful than in the picture, extremely cute, her round breasts... Wait, it seemed like there was something padded. She wasn't wearing a bra! Because she ran out of onions, my girlfriend had to go buy some. Momo immediately changed into an extremely revealing bikini. The bra couldn't cover her full breasts, her nipples were even about to pop out. The panties were so small that they could only cover her "mysterious slit", the two edges of her flesh were completely exposed before my eyes! She wanted me to take a good look and evaluate this bikini of hers, continuously making provocative poses that made me unable to bear it anymore and rushed to fuck her! Shooting all my sperm into my idol's pussy! And during the time I stayed at my girlfriend's house, I fucked her over and over again, each time shooting my cum inside her pussy, just like a dream.
