Aside from some initial cleavage tease, the boob quotient is more conceptual than it is tangible. Haley and Lane (the two cutest/hottest performers) have naturally nice-sized racks - but hardly the kind which tit men crave. Other gals hailing from the medically enhanced school fill that gap, but their scenes are markedly uninteresting.
As a matter of fact, all of the fucking herein is rather pedestrian. Crossing genres like an inebriated driver makes unannounced lane changes, Silver pays far less attention to prodigious mammaries than he does to cornholing. It's not a fatal move, just an unnecessary detour.
