Intensely, my fingers rub my clit. The orgasm explodes inside me, and I cry out. My head twists and thrashes as my body heaves. "Ohhhh..."I stifle a s...all scream. My cum blasts through my brain and wracks my body. My chest heaves. My fingers continue to massage my clit vigorously. Another wave crashes over me, the intensity magnified by my audience. Guttural sounds escape my mouth, and I enthusiastically cum for them.Gradually, I slow the stimulation. My eyes open slowly, and I see the lusty. I was his teacher. He had to learn things. Who better to teach him, and my other male students, all about sex than me? I would train the girls to be sluts and the boys to be studs.I smiled at that, my pussy clenching.And then I groaned as he reached my panties. He stroked the material, his face pressing closer and closer. He brushed the waistband, his fingers trembling. He stared up at me. I smiled back at him, giving him an encouraging nod.He hooked my panties' waistband. Drew them down.I. ...my friend met me. He had left his table too. ..Wow he said she is hot....is she "vibrating">....oh yes I told him and she thinks you are attractive...I then returned to my table. My wife and chatted throughout dinner and the conversation got hotter as the vibe continued.. We talked about some of our vacations and times at the topless beach....and even one in the caribbean were we got nude...and walked down the beach. That conversation and the vibe got her excited and she told me she might. I led her to the back yard , and unknown to her, led her to the square of light being cast on the lawn from the bedroom window where the ceiling lights were on. I told her I wanted to watch her stand & pee, so she’d better spread her legs. I heard a ‘tut’ and told her it was pitch black & no-one could see. It was very exciting to think the neighbours backing onyo my property could be watching. I walked her into the house and straight to the shower where I gave her a nice lathery soaping down..
