Arnold didn't know why it happened at the time. It would take him several more hours to learn it was caused by The Great Shift. He had just been sitting at home watching television when suddenly a man was sticking a tongue down Arnold's throat. Arnold wanted to protest, but he realized that he was also getting a certain pleasurable sensation from the kiss and was hesitant to stop it. Then the man reached around and smacked Arnold's ass. This brought him back to reality as he realized his legs were in a position of straddling this other man, except they weren't his legs! In fact, his entire body was no longer his own. He was a woman in sexy, tight spandex. Maybe that's why he didn't find kissing this guy to be revolting. In fact, he wanted to continue whatever sexual situation had already been initiated.
