We hosted an adult costume party the weekend before Halloween this year. I made a costume out of cardboard boxes that had holes in it covered by black cloth. I was not wearing anything and had things written over the openings like Win a prize! Reach in and tell me what you are touching.
Most of the guys were very interested and the first few of them were shocked to actually be touching my breasts, pussy and ass and one point there were six hands in all the openings. One of my friends put her hand in the back, felt my ass up pretty good and told me I was crazy but she would love to do the same thing.
When the party was winding down I went to my room and changed out of it and into a spider woman leotard, again nothing on under it.
