Studying teenager fingers her classmate\'s asshole.

They were studying for one of those very difficult math exams, together they had found the perfect method to study. The method consisted of spending half an hour concentrating and then having 15 minutes of pleasure and fun. This time their fun consisted of her riding his cock and him sucking her tits. With all the desire not to study, there was no better way to concentrate on their studies, than knowing that when they finished they would have such a delicious and rich reward. However on this occasion they had gone a little ahead, she had her legs spread under the table and he didn't hesitate to roam her thighs, little by little enjoying the moans she was letting out.
