Squeeze the breasts of my sister-in-law

I am a fan of Momo Sakura, a beautiful and famous swimsuit idol. I often use her photos for self-pleasure. My girlfriend Risa caught me admiring busty beautiful girls, so she made me take her to the movies. After watching the movie, Risa invited me to her house to hang out, and I could stay overnight because her dad was away. Awesome! Spending the night at my girlfriend's house surely means I will have sex with her! But just as I was about to reach heaven, her next words brought me back to reality. "My older sister is at home." Turns out she's not an only child, she has an older sister at home, so how can I "get lucky"? When I arrived at the house and was about to enter, Risa told me to wait outside. Hearing my girlfriend's voice echoing down, it seems her sister at home doesn't dress modestly? As I approached the stairs, I saw a pink lace thong transparently 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 bake a cake, her sister appeared.

And when I saw her face, I was so surprised that I fell to the ground. My girlfriend's sister is Momo Sakura! My idol! She's even more beautiful in person than in pictures, extremely cute, with a perfect bust... Wait, is there something protruding? She's not wearing a bra! Since they ran out of onions, my girlfriend had to go buy some. Momo then changed into an extremely skimpy bikini. The bra couldn't cover her full, round breasts, her nipples even seemed like they wanted to pop out. The tiny panties only barely covered her "mysterious stream gap," her flesh completely exposed before my eyes! She wanted me to look closely and evaluate her bikini, constantly striking seductive poses that made me unable to resist and I rushed to have sex with her! I ejaculated all my sperm into the idol's vagina! And during my time at my girlfriend's house, I had sex with her sister again and again, each time ejaculating inside her, like a dream...
