My little sister grew up incredibly fast. Although she's very cute, I thought she was a super serious girl with no interest in sex. But it turns out she's an insanely perverted girl! At home, my erection was discovered while facing my defenseless sister, and I thought she would hate me, but instead, she started getting excited and even straddled me, vigorously shaking her hips! Her usual seriousness couldn't have imagined such a slutty side. She drooled, begging for my cock, using obscene hip movements for continuous orgasms in fast-paced cowgirl position, demanding internal ejaculation! ※This work is a re-release featuring one character from the already released 'HUNTA-727'.
