One day, I got drunk and sneaked into her bed. The next morning, when I woke up, I found her little sister, Kasumi, next to me! Kasumi mistook me for her sister and started teasing me, seducing me... With her silky black hair and big breasts that are just spilling out... Kasumi has a perfect figure, the complete opposite of her, and my penis got fully erect without any hesitation! I was completely hooked on Kasumi's sexy body and slutty techniques, and I was definitely in the swamp! Face sitting, tit fuck, creampie sex... a total of 4 shots. 130 minutes of being toyed with by her little sister's big-breasted body.
