My girlfriend and I are both very ordinary people. We have no interest in perverted things and just want to enjoy normal sex. But then her older sister showed up, twisting my sexual desires and driving me insane! Her cleaning lady persona makes her completely unaware of how exposed she is, showing off her huge ass and gigantic cleavage. And when she wears that T-back thong that seems to swallow her massive butt... It's all so fresh and addicting! I can't help but fantasize about pressing my face against those see-through panties until I cum, or having her ride on top while I stuff myself inside her tight body, feeling every inch of her weight crush me. Ugh... Today, like always, I'll cheat on my girlfriend to satisfy these warped urges. *Note: Content may vary depending on distribution method.
