Her younger sister is prettier than her, has huge breasts, and seems to love me so much that she always seduces me with her no-bra boobs. When she's away, Shion always makes a grinning sex appeal and asks, "Do you want to have sex?" I was at the mercy of such a girlfriend's sister, and finally I was the worst person who ended up being able to erect a dick only with a big boob... "It's a secret to my sister" I lost to the temptation of my little devil sister's boobs and I couldn't stand it when she was there and had public cheating sex!
