Girl at the mall

I was eating at the food court when a mother and daughter sat at the table in front of me. The mother's back to me but the young daughter facing in my direction. Dressed in a tight tank top and jean shorts, this young woman was very cute. I would look up occasionally and she would look over to me a few times too. We soon mustered small smiles at each other. She blushed a little. After a few moments she started to spread her legs under the table, showing me her crotch in those tight jean shorts. She'd let me look for a moment before closing them. She kept on doing it for a while, eventually she took her hand and rub her crotch gently for me. I couldn't believe what i was seeing. My dick was super hard. They finally got up to go. I rushed to throw my food away and I followed them for a little. She went into a store on her own and I followed her there. we bumped into each other and we very awkwardly says hello. Behind the stall of clothes she grabbed my crotch and rubbed my cock. i stood behind her as we pretended to look at clothes. I started to grind my dick into her ass. But I got paranoid that we were too obvious. I took her by the hand and found an empty changing room. We got inside, locked the door and looked at one another. Both breathing heavy I started to undo my pants. I pulled my cock out and she got on her knees and sucked my cock. She was shy and it was a little too big for her small mouth. I soon came in her mouth and on her face. I wiped her face with a shirt that had been left in there and told her to leave first.
