A couple of the other guys sweating in the sauna had also been saying hoompa hoompa hoompa, trying to be like Sean and Mace. So pretty soon all the guys are jacking themselves up taller and taller, laughing and getting turned on, and everyone's got three or four pairs of crossed legs, except for Sean and Mace, who had even more, and were helping each other get their big stiffies into each other's holes, since they had so many of them now.
