No sheepskins required for this course of action. You don't need a high school diploma - or even a G.E.D. - to know that a foursome with three guys and a girl does not exactly add up to a gangbang. Nevertheless, the cast demonstrates two watchable scenes of reasonably arousing sexual education.
The principal scene involves Lena, who goes to the head(s) of the class with Rod, Arnold and Tyler as they take turns stuffing her hole-y trinity. Plenty of pull-outs and re-plunges into her backdoor box clearly excite this slut, who graduates to magna cum louda more than a few times in one session. It would've been nice to see more reaction shots of her face while undergoing this endurance test, but at least the viewer can hear her mouth-stuffed muffled yelps of pleasure as Rod cockteases her asshole while the other guys take turns at other points of entry.
