While Mom is not home, a young chick fucks with a friend instead of classes

A guy gets turned on by science and smart girls, so he comes to visit his girlfriend to do her homework together. While her mom is not home, the guy gets very bold, so he gropes the girl's leg, hinting at intimacy. The brunette relaxes and acts normal, even showing her boobs to make the guy feel even more attracted. He slips his fingers into the young babe's pussy and then makes a cunny to get a quicker insertion. The chick is happy to start fucking, as she intends to have an awesome orgasm.
