We sat chatting and laughing and I can't remember how it happened, but we began playing truth or dare.She was far more out going than I was and it was... her who dared me take my sweater off, my bra was clean but not particularly sexy and I felt the first flush of excitement as I dared her to do the same.Pretty soon we were down to just our panties and then she changed the rules,"I dare you to take my panties off" she said softly and smiled at me over her glass, I was drunk enough by then not to.

Her movements were random.
