אח חורג חרמן מלמד מתמטיקה עם התקדמות מינית

A steamy family fantasy unfolds as a nerdy stepbro finds himself tutoring his younger stepsis in math. The petite, skinny teen is eager to learn, but the stepbro's inability to concentrate leads him to make a suggestive proposition. He offers a trade - if she lets him feel her up, he'll help her ace her math test. The young girl, initially taken aback, soon gives in to the temptation. The stepbro's hands explore her petite frame, causing her to fantasize about riding him. As the heat rises, the stepbro loses control, and the young girl straddles him, riding him hard. This intense encounter leaves them both breathless, but the stepbro manages to keep his promise and helps the girl ace her math test. This wild ride is just the beginning of their erotic exploration, with more steamy encounters to come.
