It wasn't long before Jen found a fellow cheerleader by the name of Alice. Without wasting any time, Jen pulled her aside and said, "Transform or dare?" and then clamped her hand over her friend's mouth. She didn't want to risk the wrong answer and this would just make things easier. As Alice stared at her and tried to get Jen's hands off, Jen only smiled. She was so close and her pussy needed it so bad.
After a minute, Jen let go. "You didn't say anything so you get both," she explained.
"What are you talking about, Jen? What's going on? Why did you grab me?" Alice pulled out a mirror to check her makeup, afraid that Jen had smudged it.
"Don't worry, you'll see." Jennifer paused to make sure she got her wording right. "Alice, your arms will turn into long, thick tentacles covered in slime. Every time you pleasure someone with them, even yourself, you will grow another tentacle from somewhere random on your body, though you'll always look mostly human. When not in use, you can retract your tentacles into your body, except for your arms." She stopped, flushed. Just the thought of what she was doing to her friend was making her so horny. Jen reached a hand under her skirt and started fingering her clit. She had forgotten to wear panties that morning.
Alice, meanwhile, was staring at Jennifer, completely shocked. "What the hell are you talking about? That's so totally gross!"
This seemed to snap Jen from her trance. Still pleasuring herself, she continued. "Mm, for your dare you, ah!, will take pleasure in fucking girls with your tentacles whether they want you to or not. The more you fuck at once, the better, and you're not afraid of fucking yourself." She bucked her hips a little, into her hand, grinning. The changes were about to begin.
