I was riding the bus next to a dirty old man with a box on his lap. I sit down by him and subtly flash my cleavage, and then my panties at him. His ey...s got big when he caught site of my nipples or my clean shaven pussy peeking out from my white underwear. I could see that he was getting a noticeable bulge in his pants. His cock was sticking up just between the box and his fat stomach, and no one’s could see it but me.So, I sat up and put my hand on his crotch. Then, I started slowly wanking. It was more than flirting. She was playing up to him like a sycophant, touching him, flipping her hair. I could understand the choice if not the behavior. He was about five years younger than us and had lost little of his good looks to age. Sally was 5'10" in her three inch heels so he must have been around 6' tall. Unlike mine, his hair had no gray. He was not heavy and looked classic in his blue suit. Other women would flirt with him at these parties but Sally seemed to have taken it to a new. " She said as her eyes panned the mega store. "Oh my..." she said again. Her eyes were wide open and her expression was blank as she panned. "Lead the way" she said to me.I casually lead her through the store. We looked at vibrators. We looked at butt plugs and dildoes. I patiently watched as she allowed her curiosity to flow. I answered her quiet questions, particularly about some of the toys she knew I owned...As we made our way very casually towards our goal, the harness rack, I skipped. I wanted to taste her juices. I wanted to fuck her mouth. And I also knew I wanted to touch Mark. Would he freak out? I kept licking her breasts and tight stomach. But now, while on my knees face-pumping her, I thought -- fuck it -- and took my two hands to grab Mark’s shoulders (like resting on them), as if I needed help with supporting myself as I kept moving my lips and face down her body. He totally went with the flow and let me lean on him like it was no big deal. In fact, Mark.
