We are rapidly running out of orifices to cum in. "Up the Nose!" is the obvious next choice, but past that the "pickings" are going to be pretty slim. "Ear Wax Sluts" doesn't sound like a best seller unless the audience mis-hears the claim that it features "All Aural Sex".

"Cum In My Armpit" will likely only catch on in Europe. And I doubt that there are enough hot bitches with tracheotomies to fill sixty minutes.
