Buying dessous and stuff

Hi there.
I want to share a fantasy with you.
We go shopping and you choose some bras and underwear and bikinis. You ask me if I like it. I look at you and nod.
Then you go into the changing room to take off your bra and underwear and to try a bikini. You ask me if I like it again.
Since I like what I see I nod again.
But after looking at you for a while I got a bulge in my pants and you saw it. You seemed to like it so you asked me to follow you in the changing room. The risk of getting caught made you excited so you started to ride me.
