Even as you read the warning, it's already too late.
You push into your piggy lover harder and harder, feeling nothing but pleasure as you do it. The worry in your mind is lost in that moment, and before long you feel yourself let go and climax and hear your piggy bride squeal with delight.
You both tumble off the bed and asses the damage. You're both undeniably pigs now. Large, pink and bristly.
It isn't long before the door opens and a couple of workers appear. "OK, we have these two to collect. Boar and sow, it seems." You don't want to go with them, but they expertly guide the two of you into a floor level cage, then slap the door shut. You squeal in protest, but they ignore you. "Take them to central processing," the one in charge says.
"What's going to happen to them?" the younger one asks.
"If they're lucky, management has a buyer with a thing for former humans. Sometimes they end up as someones super-smart pets. If there isn't a buyer like that, then they get sold to a farm somewhere. She'll pop out a few piglets before they both become bacon and ham." The man shrugged, "If there is no buyer, we may have a nice luau on the beach in a few days with them."
