[I said I was just going to rub it against her panties, but when I inserted it through the fabric, my girlfriend’s sister got turned on] I accidentally saw my girlfriend’s sister’s panties… Her plump ass and thighs were so erotic that I put my hand on her so she wouldn’t notice! “I won’t put it in” “I’m just going to rub it against her panties!” I inserted it through the fabric so that it was sinking into her pussy, and my girlfriend’s sister started to feel it! “This isn’t good enough, I want to have sex” When I inserted it into her soaking wet pussy and started to thrust it violently, my girlfriend’s sister got even more turned on… [Hey, I want to drink your sperm] [Don’t go too deep] [Forbidden acts taste like honey] [A secret between just the two of us]
