Whip

A whip might be good enough. This way you could at least have some fun.

John: "How about a whip? It's more of a toy, and they should be fine with someone getting whipped."

Kelly: "Wtf thats going to hurt."

John: "We don't have to do it hard. At least it counts as a toy."

Kelly: "Fine, just be gentle."

She hands you a black whip. You give her a smirk and head over to cash out.

Cashier: "You having fun on your little dare night?

John: "How do you know about that?"

Cashier: "You two aren't the first couple coming in tonight."

Kelly: "What did the others buy?"

Cashier: "Well I'm not supposed to say, but seeing as you are all recording it and sending it to each other I'm sure you will find out eventually."

John: "Come on, we just want to know if they got something more **** or less **** than this?"

Cashier: "Well one group got a vibrator, another a dildo, a paddle, nipple chains, and a butt plug. That's all I can remember from people around your age. This would be one that you have to be careful with."

Kelly: "Could you help us out? I'm not trying to get hurt."

Cashier: Sure, I know you have to use it later, so might as well do it here. I can record."

The cashier shows you how to use the whip. You eventually figure out how to make it crack.

Cashier: "Ok so that's not what you are going to do. That will leave a scar. Be a little more gentle."

You slowly get in down.

John: "Ok Kelly, I think I'm ready."

Kelly: "Don't fucking kill me!"

John: "I won't don't worry."

She turns around and bends over a little. Only one place to hit. You give the whip a swing and it smacks her right on the ass.

Kelly: "Oww holly fucking tits."

Cashier: "Ehh pretty good for your first time."

Kelly: "I'm going to need some ice."

You head to the car to go back to the group.

Kelly: "So what dares did you do while we were gone?

Lana: "They ate sushi off my ass."

{ft3}: "Well I got fucking whipped."
