Friends cum on their assignments

Sheril and her friend spend the whole day studying. They make themselves comfortable in bed and try to cope with all the assignments. Some of those tasks turn out to be a hard nut to crack and this is why Sheril asks her friend for help. They sit pretty close to each other and soon realize their breaths mix and they can think only about fulfilling some of their sex fantasies right on textbooks with those hard assignments. So they put everything away, undress each other and take one position after another till they both get desired satisfaction and till dude is ready to feed Sheril with sperm.
