I'm a fan of Momo Sakura, a beautiful and popular swimsuit idol. I also often use her pictures to masturbate. My girlfriend Risa found out that she was watching a beautiful girl with big breasts, so she forced me to take her to the movies. After watching it, Risa invited me to go to her house to play, and I could also spend the night here because her father was away. Great! If you can spend the night at your girlfriend's house, you will definitely get to fuck her! But as soon as I finished going to heaven, I was dragged back to reality by her next sentence. "My sister is at home." Then she is not an only child, and with an older sister at home, how can I "fat" anything. As soon as I arrived at the house, I was about to go inside, but Risa told me to wait outside. Hearing her girlfriend's voice echoing down, it seems that her sister is usually not dressed properly when she is at home? Stepping up to the stairs, I saw a see-through pink lace panty thrown on the stairs! My girlfriend quickly hid it, thinking it was hers, so I didn't think much about it. While waiting for his girlfriend to make cakes, her sister appeared. And when I looked at her face, I was so surprised that I fell to the ground. My girlfriend's sister is Momo Sakura! My idol! She is even more beautiful than in the photo, extremely cute, round breasts... Wait, it seems that something is padded on it? She's not wearing a bra! Because I ran out of onions, my girlfriend had to go and buy them. Ms. Momo immediately changed into a bikini that was extremely lacking in fabric. The bra couldn't cover all of her plump breasts, and her nipples even wanted to pop out. The panties were so small that they could only cover her "mysterious stream", and the edges of the flesh completely appeared in front of my eyes! She wants me to take a closer look and evaluate this bikini of hers, constantly doing provocative poses that make me can't stand it anymore and rush to fuck her! Shoot all the sperm into the idol's pussy! And during my stay at my lover's house, I fucked her over and over again, cumming in her pussy every time, like a dream...
