You have always been friends with CherryBomb, yet she had never allowed you to tickle her. She had never liked those kind of things and always avoided them with any excuse. But that night you were both at the club and she was high. Like, really high. And all her defenses were completly down, so you decided to not only take care of her, but slso take advantage on the situation and tickle her.

(You can continue as you want. I was so lazy on this one, I'm sorry)
