The younger sister I met for the first time at her house was a kinky J-girl. I couldn't help but stare at her big boobs, which were visible even in her uniform, and her big ass, which peeks out from under her miniskirt. From the moment her older sister left the house, she was cheeky and started teasing me, purposely flashing her panties and asking, "What are you looking at lol." I thought I'd hold back because she's my girlfriend's younger sister, but I couldn't resist my dick and desire, so I grabbed her big ass and immediately stuck my adult dick in her! I came inside her pussy, which was moaning and leaking, over and over again.
