So on this day I had seen her panties and had been picturing her naked and thinking of other things I’d like to do to her while I sat there in class...waiting for the bell to ring. When class was over she really embarrassed herself and me when she saw the bulge in my pants and thought I was trying to conceal something as I walked out of the classroom. She stopped me, pointed at the bulge that I was trying to cover up with books and said, “What is that you’re trying to sneak out of here. She held it so that the tip jutted into her opening and said “Now there, just push up in there Mikey.” I edged forwards and started to push up into her as she eased herself down a little to help me and then I was in her! I was actually inside a grown woman’s cunt!“Now just hold steady for a moment,” she instructed as she moved herself to a more comfortable angle against the tree. I was mesmerised and just did as I was told but my cock wanted so much to move inside her now. “Ok, try to go slow. My breathing became laboured as I furiously drove my fist up and down the length of my cock, panting like a dog as her teasing smile played on her lips. I was doing this for her amusement and nothing else - where her lovers would have enjoyed the freedom to roam her body, this is what I’d been reduced to - a quivering, kneeling horny slave boy, eager to please and obey. I grunted and spurted my load over her stockings, whimpering as she let out a moan. Clean, she smirked. I have a date to get. She drummed one of her hands from her hip and just stood there for a second. I could see in her face that she was re-grouping her thoughts because she didn’t get the answer she thought she was going to get. “What I want to know is, why are you masturbating when you have a wife and can get relief just about whenever you want?” “Well…. I’ll tell you why…” I said. I picked up the porno magazine I was looking at and held it up, showing my wife pics of women sucking cock and eating cum..
