Then there Rebecca and Tess. While the other four pairs of pig people were happily mating, they still hadn't changed, much to the annoyance of their johns, Trevor and Hector. They stared blankly at the pretty, but still very much human, girls.
"What's taking you two so long?" Said Trevor with an annoyed voice.
"How are we supposed to know! It's not like we've done this before!" Rebecca spat back. It's not like she was in any hurry to become a pig person.
"I'm tired of waiting." Said Hector as he trotted on over to Tess.
"Woah! What are doing?!" Tess exclaimed as Hector got a bit to close for comfort. He pulled up her skirt and took his dick out. Tess was surprised, but she wasn't quite fighting Hector, some part of her knew, this was how things were supposed to go. Still, the feeling of a large corkscrew dick being shoved into her as was a new one, and she reacted accordingly.
"Wooah! WOAH! WOAAAOINNK!" Said Tess as Hector's thrusts began to initiate the transformation proper. Her face quickly pushed out into a snout and weight began rush onto her body. The increase in mass was startling and Tess fell backwards onto Hector's crotch.
"You ok?" He asked.
"Oooh yes," she cooed. "I've got plenty of cushion for the pushin' now! C'mon, let's keep going!"
Trevor saw Hector's success with Tess and moved in on Rebecca to initiate the same. Rebecca was not having it.
"Oh no! Don't you go getting any ideas big guy!" She said as she tried to back away.
"Rebecca! Don't fight it! It feels so GRRROOOOINK!" Exclaimed Tess as another of Hector's thrusts pushed her transformation further along.
Rebecca wouldn't have much choice in the matter, as Trevor pulled up her dress and gave her a powerful thrust into the booty.
"No! NOO! NOOOOIINK!" She squealed as she finally realized the pleasure of the transformation. Trevor and Hector kept at it. Helping to bring their mates into full pighood.
