“If you shoot cum into my pussy like that, it won't leave any traces, right?” I was seduced by my girlfriend's sister. She has a perfect body, a beautiful and demure face, but deep inside is a wild animal that is always hungry for sex! As long as my girlfriend is absent, she will find every way to squeeze out all my sperm. Because in order to avoid being detected, she used her mouth to suck them all the way to the end every time and swallow them all. She even hid my sperm by letting me ejaculate all inside her uterus! The feeling of excitement and fear of being discovered made me feel even more horny. She continuously sucked all my sperm, not even leaving any for her sister! Clean sperm also because of my girlfriend's sister
