Ian and Robin, two horny students, start a sextoy business. They decide to test one of their products on their friend Mark, who volunteers his ass for the trial. He spreads and makes his hole available, and the two buddies watch to see if the sextoy works. Watching Mark get pleasured with a dildo gets everyone horny, and he ends up getting fucked by his two hung friends. Business will wait, there's a hot ass to satisfy.
