Teen Student Vivien Doll Took Her Math's Teacher's BBC

Viven is pretty cute with delicious round ass. I was her teacher in grade school. She was not very bright in maths so one day her parents sent her to me for an extra after-school math lesson. I was eagerly waiting her arrival at my house since she caught my eyes in class with her perky round ass and have ben fantasizing fucking her ever since. I sat her on the sofa to begin her math lesson but I couldn't help noticing that she arrived without pants underneath her skirt. hmm.. makes me wonder if her parent really sent her to me for math lesson or they actually want their daughter to experience her first BBC.
