He was wearing his best shirt, a pine color, with beige chinos, and loafers stylishly without socks. He had even put on aftershave, something he rarel... did. Dinner was excellent, and they talked of many things, including Mark's ambitions. He was looking to attend collage after finishing school and study law. He had been brought up hearing chapter and verse on how Helen had been wronged by a legal system that was stacked against her. It was one of the few things she ever got bitter about, and. I was nervous but we were all drinking some liquid courage. I was already topless and though what the hell, he's seen everything. I just took my bottoms off and jumped in the pool. Climbed back out and was sat fully nude in front of my hubby and a stranger. Conversation was difficult but the alcohol helped. I decided to take things up a notch and start flirting with them both. Started kissing my hubby then sat on his lap. He kissed me deeply and played with my boobs then my pussy. This was it.. It was quite noticeable how much louder the spanks were as well as the teachers gasps. Again we ignored their cries and their kicking legs and landed harder and harder spanks non-stop for the final two minutes. When we stopped I realised that Mrs Bell was sobbing and Miss Hopkins was actually crying. I was so sorry now that I had agreed not to tell anyone and started to wonder what the worst that could happen if I did tell my friends. I put the thought aside for later. We let the teachers lie. ." I asked what that meant? She just smiled.....On the way thru the parking lot, I realized she was right about her wet pussy running into her dress. There was a big wet spot, about 4 inches across on the back. I decided not to tell her. As soon as we got in the store, she led me to the fitting rooms, where there was nobody at the time. She immediately grabbed my cock thru my pants, started unzipping my pants and dropped to her knees.The bottom of the fitting doors were a good height off.
