Thanks for your comments – It was a busy evening. I was parked facing the super-market entrance at two minutes to nine. My phone buzzed, a txt from Maurice. 'tell your husband I want you for a whole night'. I ignored it. At five past Duncan came out looking left and right. He didn't see me and looked slower, left and right. I flashed my head-lights. I saw his face light up. He walked towards me as I opened the passenger door. “Hello Duncan, get in.” I told him. He looked surprised. “How did you know my name?” he asked. “You were wearing your name badge.” I grinned. “Do you still want to discover if I didn't forget my panties again this week?” Surprise changed quickly to alarm. “Here?” he stuttered. “Where do you live?” I asked. He lived with his parents, was 17, a virgin and he didn't have a car. It took him about an hour to walk home across town. He knew somewhere we could park. I knew it too, where Tony and I had enjoyed exploring each other way back when... It took only a few minutes in the car. He didn't have a girlfriend. Mine was the only pussy he had ever seen and had never seen naked tits. He had seen lots of pictures of both. “Do you wank when you look at the pictures?” It seemed a reasonable question. He nodded. “What do you think about when you wank?” He told me he thought about 'doing things'. “Did you wank after I flashed my pussy for you?” He flushed scarlet before replying “yes” in a small voice. I pulled into the shadiest corner of the car park. I knew it well and it hadn't changed much. “Duncan,” I said, “there is no need to be embarrassed. I would have been very upset if you hadn't had a good wank while thinking about me! Now, what things did you think about doing while you wanked?” “I thought about seeing it again, then touching it and stroking it and putting my fingers in it.” he said. “You didn't think about fucking me?” I teased. He told me he came before he got that far but had thought of nothing else since. I thought that was very nice. I moved the car seat back, put the back rest down as far as it would go and turned a little to face him. “Are you going to lift my skirt and check for my panties now?” I'd seen that look before. One of delight mixed with embarrassment with a much larger dose of horror! Alarm bells rang loud, back off a voice screamed in my head. Where had I seen it? “Tell me about yourself, there is no hurry, it's not even twenty past nine yet.” I coaxed. He talked and I listened. I hid the shock very well I thought. Certainly Duncan never noticed. So, I had a twenty eight year old married son and two grand-daughters and Adam had a seventeen year old virgin for a son. Everything shouted at me to run away except something inside me argued that he's legally old enough, he doesn't know me from Eve nor my relationship to his dad. And he reminded me so much of the boy I once worshipped. Duncan was much more relaxed after his monologue. “Would you like me to show you again, like I did in the store?” Duncan nodded eagerly. I started to ease my skirt up my thighs. “I'll show you mine if you'll show me yours.” I told him. That made him laugh. “You sound like a little school girl.” he said with a smile. “Well, this little school girl has shown you her pussy once already and she wants to show you again but she also wants to see your little willy.” I told him gently. “It's not that little,” he replied, going red. “Have I made it hard?” I asked with a big grin. He nodded. “Show me!” His hand hovered over the zip in his trousers. “Shall I do it for you?” He looked at me, his nod so slight I nearly missed it. I reached over, unbuttoned and unzipped. Give him credit, he moved about to make it easier. I told him to lift and then eased his trousers down to his knees. 'Y' fronts! But at least they were coloured. There was an interesting bulge which I traced with my finger. It stopped just below the elastic top. I hooked a finger over then looked him straight in the eye as I lifted the material up and over his bell end. He helped me work them down to his trousers. I looked down. It was beautiful, pink, smooth and straight. Just as I remembered his father's. I wanted to kiss it. I didn't. I wanted to touch it. I didn't. I sat back and raised my bum from the seat. “Now it's my turn,” I told him as I lifted my skirt up to my waist. I twisted back to face him and opened my legs as wide as the space allowed. I was fully exposed to his eager look. For my part I looked at his pretty cock. His cock was responding as was my cunt. “You said you thought of my pussy when you had a wank?” I asked. 'yes' he replied in another small voice. “Well now I'm going to wank while I look at your pretty cock, OK?” I reached down and started to stroke myself very gently. I didn't want to cum too quickly. I had regularly pleasured myself while fantasising about his father. Mark had introduced me to the joys of wanking while he watched and watching while he wanked for me. At first I felt a little uncomfortable but that only lasted a few minutes, the pleasure of being watched totally wiped out any embarrassment and the first orgasm was overwhelming. “Tonight, I want you to wank and think of me frigging myself, can you do that for me?” Duncan nodded, not taking his eyes from my wet love hole. “And tonight, when my husband is snoring beside me I'll reach down between my open legs and stroke myself while thinking about you having a wank, would you like that?” Again he nodded. “Show me how you stroke your cock, so that I can see it in my minds eye and imagine I'm stroking it for you.” Make or break time! Will he chicken out or will he... Duncan reached for his cock, wrapped his fist around it and started to wank. I loved it! I love watching Mark toss himself off and it's much better if his load lands on my face or tits. I continued to frig myself, gently. “Take your time, don't make yourself cum, try to stop just at the last moment!” I told him. I watched him intently, his hand moving a little faster with each stroke. “Are you on the verge of cummin?” I asked. He grunted. “Stop!” I told him, “Think of,” I paused momentarily, “cold custard and semolina!” “Cold custard and semolina?” Duncan laughed. “Can you think of anything less sexy?” I retorted, “Anyway it worked!” I added with a grin. “Do it again, but don't cum. I want you to bring yourself up to the top then stop and let it subside, OK?” he nodded looking a little nonplussed. “The longer you can make it last the better the eventual climax will be. You are not to cum until you are in bed, thinking of my open wet pussy and wanking. You must bring yourself to almost cummin three times. The forth time I want you to throw the covers off so you can watch it spurt your spunk. Can you do that for me?” He said he could with the same beautiful smile I remembere his dad having. We wanked together and I watched for him to think of cold custard and semolina. Then he watched me until I had to think of cold custard and semolina. We spent the next twenty minutes watching each other wank, both together and one at a time. I dropped him off at the end of his road at five to ten. I didn't want to see his house. He had a raging hard-on, so hard it was difficult to get him put away properly. Ten minutes later I received a txt saying 'thank you xxx' which was very welcome. There is more, if you are interested?
