In between classes students at the University are given every opportunity to practice their skills. The best way for them to earn passing grades is for them to keep passing huge cocks in and out of their sphincters day and night until the hole feels right.
One of the newer techniques being used at the school to get girls used to the uneven motion of getting their asses porked is that of trampoline kinetics. In this advanced course one girl attempts to maintain the right angle for her ass to be deep fucked as another girl forces a dildo into her while making her body flex on the trampoline. This is great practice for all the ladies to try at home.
This would not be much of a University without a tennis team but the girls have to learn that every activity is a great time for some anal. In this scene an important opportunity is missed when the blonde anal sex student forgets to take the garden hose out of her mouth long enough to force it up her ass. Don't be too hard on her, she is still learning.
