Mario could barely concentrate on his daily activities, waiting for evening to arrived. By nightfall, Adam had dismissed the vague memories and oddly missing time. Mario waited for Adam to finish his shower. When he entered wearing only a towel wrapped around himself, it seemed like the perfect opportunity to try the trigger word.
"Sooeey!" Mario said with a smile. "Sooeysooeysooeysooeysooeeeeey!"
Adam turned. "What?" he asked puzzled, but a second later he transformed. The towel flew off as the muscular male once again became an obese, flabby, multi-titted pig woman. With a heavy thud and an oink, she dropped to the floor on her huge padded ass.
Mario chuckled, even as he unzipped his jeans. "And how's my Miss Piggy this evening?"
The sowgirl tried to reply, to beg for the cock Mario was revealing. But her voice had been taken from her earlier. All she could do was give a pleading squeal. But Mario knew what she needed. In this sowgirl body, Adam was addicted to spooge, craving to swallow as much as she could get. For the next hour or so, Mario played with her. He got a blow job from her blubbery lips, then screwed her, then got sucked off again. Normally females weren't of much interest to him, but knowing it was Adam deep inside there made all the difference. And best of all, he could transform his roommate any time he wanted. Adam would never know.
Finally, Mario was spent. Even a pound of Viagra wouldn't revitalize his tired cock. He lay on the sowgirl for a time like she was a living beanbag chair. Voiceless and too heavy to move much, she could only lay there. Finally Mario got up, cleaned himself off a bit, got ready for bed, then said the trigger to change Adam back to normal.
