내 수줍은 배다른 여동생이 내 속옷으로 자위하는 걸 포착하고 내가 그녀의 엉덩이에 사정할 때까지 그녀를 열심히 따먹는다.

My stepsister discovers me when she enters her room and watches me masturbating with her underwear. When she realizes she complains to me why I do that, I seduce her and say that I like the smell of her underwear too much and I end up fucking her hard until she makes me run.
