Little Ariana is getting ready for college and needs some extra tutoring, and it's hard to find a better tutor than her friend's really smart dad. It looks like it's going to be a very long day because Ariana doesn't know anything about biology and her teacher is having a terrible time concentrating because the student looks so slutty. They start discussing sex, so very soon the couple moves on to practical activities. The mature stud quickly managed to bring the beauty to orgasm and poured a lot of sperm on her himself, after which she returned to her studies.
