Everything was going great. Karyn was having some of the best sex of her life and Biff also seemed to be enjoying himself, through his drunken haze.
But a few minutes into their lovemaking, Karyn began to feel ... strange. She pushed Biff off of her and asked in a slurred voice "What was that?"
"Huh?" Biff asked, not understanding what she was talking about. Then he watched as her belly began to swell up. He backed away and fell onto the floor. "What the hell?"
Karyn stared down at her swelling belly with shocked eyes. At first, she thought she was imagining it, that the alcohol was making her see things. But when Biff reacted to it too, she knew this was no hallucination. Something was definitely happening to her.
When it finally stopped, her belly was so big, it almost looked like she was pregnant. But that's because she was.
"Oh god," Karyn said. "I can feel it kicking."
Biff stood up, then wobbled a bit from being drunk. "What's kicking?"
"It's a baby," Karyn said. "I'm pregnant."
"How is that possible? You can't get ... hey! What the fuck?" Biff slurred, looking down at his still-erect penis. As he watched, it started to lose its stiffness. But it didn't just return to its normal size. It kept shrinking until it stopped at a pre-puberty size. He rubbed it, trying to make it erect again, but nothing happened. How was he ever going to have sex? "What the hell is happening?"
"There. The curse has been cast," Kyla said, with a smile. "I hope that bitch appreciates it, because she's gonna have it for a long time."
Kyla and her Goth friends fell into a fit of laughter. Revenge was sweet.
