"So..." Mary asked, her curiosity getting the better of her, "did your box just... show up too?"
"Yeah,'bout a week ago..." Mike answered, his face looking all the more hoglike, lower teeth beginning to protrude into tusks. God, Mary loved it. She started to wonder why she would ever want to be human when this felt so right and he looked and smelled and sounded so good.
"And you just tried it, right?"
"No hesitation. It was weird."
"Right? We could have been poisoning ourselves! But something in me just..."
"... Trusted it," Mike finished her thought, his face pushing out into a snout to match hers. "I saw yours arrive before, and I just knew. I knew you'd try it and find just how... wonderful it is. Didn't think you'd have a friend over though, lucky me."
They both looked down to Jess, who aside from the strained and seam-busted remains of her clothes, and the hair atop her head, didn't look human at all. She was almost entirely a sow, and almost entirely out of food.
"And so you came on over," Mary said, looking back up to Mike. Jess was oblivious to both, lost in what she could only assume was the euphoria of having changed so much. She remembered well her first change. She was lost to it for hours.
"Ba-Dee ba-dee ba-Dee ba that's all, folks!" Mike said with a throaty grunt of a chortle.
"Well, Porky, if we're gonna play that game, we'd better look the part," Mary said, standing up. She hadn't changed so much yet that she couldn't stand on two legs. She was pretty well balanced between woman and sow at this point. Mike watched eagerly as her hoof-like hands went to the waistband of her pants and shoved downward, a move that was intended to pull them off but destroyed them instead,tearing them in half.
"Oh..." Mike's eyes went wide, jaw quivering a bit.
"Now let's see what you got, you big fat sexy boar," Mary said, punctuating her porcine seduction with an oink.
