Q. How do you embarrass an 18 year old female cousin?
A. Pants her in front of the whole family on Christmas Day.

This happened to me yesterday. We were all at our grandmother's house giving and receiving presents as you do. I stood up and walked over to one of my aunties to collect the gift. As soon as the gift was in my hands my little cousin (15) pulled down my jeans. I froze with embarrassment standing there with my flowered patterned, black and red, frilly laced panties on show. As quick as that happened there was an uproar of laughing. I ran out of the room without pulling my jeans up.

Now I am planning revenge, I don't know whether to make it a private humiliation (ie just me and him, making him do the very worst of things) or make it a public one (ie pantsing in front of whole family)...

Ideas people...
