Now that I was teasing more than just Gail, I was ready to escalate the game. I had her turn over so that she was face up. She checked out our watcher... and settled back with her hard titties facing the sky. Leaning over I took a rigid nipple into my mouth and sucked greedily. I spread her legs and began stroking her fat pussy lips with my hand. Spreading her swollen lips I allowed our watchers (yes, watchers, because the woman was now caught up in the action) to see deep into my lovers pink. She saw a guy in the back of the store making artist easels and you could see the light go off in her head. She hustled back to where we had looked at some close-out fabrics and she fumbled through the unsold partial bolts. She brightened and said "There it is!" and pulled out a light colored denim that had a lighthouses and nautical pattern. She took out a tape measure and started measuring, apparently the distance between the lighthouse in the design to the next time it showed up. The fabric.

Mom was facing us and doing what they call a Reverse Cowgirl. This is where the guy is flat on his back and the girl mounts him wile facing his feet. It's great if the guy really likes your ass.The other advantages to this position, and there are many, is that you can set your own speed and depth,. Was this the requirement I had to meet? Was I to stand here and let her rub me off in my own pants again?The brunette giggled and looked over at the two blondes. “I found someone for us to play with.”I looked back at her, knowing exactly what she meant. The two blondes apparently didn’t agree with the idea though. Without uttering a syllable, they turned and walked away, disappearing around the next corner of the building.“Party poopers!” Francine called after them, and then turned to look at.
