Rockhard!.

This gay tale shows the ups and downs (and ins and outs) of a young geologist as he takes a group of his male students into the scorching desert on a field trip! Everyone has the hots for everyone else, so very little rock exploration goes on...but lots of male flesh and sex positions are explored! The sun is super hot which makes all these dudes very, very horny, so back at their motel all sorts of combos are tried and enjoyed! The cum-loaded finale has all the students humping and pumping...with our eager professor joining the action! Formerly titled "Rockhard Vein."
