Spanking Leads to Unusual Wanking

Quite a while ago, at a time of my life where I was making tentative sexual explorations, and had several women friends, I used to hang out with Janine. We weren't dating but would go out to music and dance clubs or have drinks together from time to time. We never had intercourse sex but would play together sometimes. We experimented. One of us would put on a blindfold and strip off, or the other would undress the blindfoldee. Then would follow an exercise in slow, sensual massage with fingers, breath, lips, tongue, bodies. Wearing the blindfold, you never knew where or when the next touch was coming. That was highly arousing once you got a little warmed up. It would end in a teasing approach to climax with lots of stops and starts usually resulting in prolonged orgasm, or several if she was the recipient. After, the giver would usually get some relief though occasionally we saved it for next time. If Janine had been the giver, I would go down on her, may favorite pastime. I was always amazed at how wet her pussy would be after massaging me to orgasm, and her lips be opened out like rose petals. If I had been the giver, she would sometimes take my cock in her mouth, or stroke me  in hand but she most enjoyed watching me stroke myself off. When I came I would always hear a murmur or sigh of satisfaction from her. She would be sitting motionless, eyes fixed on my hard cock, its swollen head, and the cum pumping out of it. That was alway so erotic to hear and see her like that, the icing on the cake. Janine live in a basement apartment. She told me that since she had moved there she had a strange dream that repeated every couple of weeks. In it, a strange figure would appear riding on a donkey in a carnival procession. The figure was short, thick, dwarf-like, and sported a huge phallus like a tree branch that stuck straight up from his groin to his eye-level. Any of you from the UK who remember the old Punch magazine will recall there was a figure like that in the little header engraving they put at the top of the content page. I think it came from some old Italian Renaissance sculptured frieze. That was the dream. The figure just appeared. It didn't do anything but did project a strong, earthy, sexual energy that Janine found a little unsettling. Fast forward to one evening when we had been out at a friend's party and stopped back by her place, a little tipsy. Somehow our conversation turned to erotic spanking which neither of us had tried. We decided to experiment right there and then. She went first, over my knee - we didn't even take any clothes off! - a few hand swats on her ample ass -- and she knew this was not for her. (Since then I've given a few spankings on request to women friends who did find it a turn-on. I learned about myself that giving a spanking turns me on if it's turning my partner on but not otherwise). So, change positions. My turn. Janine on the sofa, me sprawled across her lap. I'm wearing thin khakis. She delivers the first slap. It stings and tingles just a little. But then she reaches between my legs and massages and squeezes my balls through the trousers. A jolt of electricity shoots through me. Another slap followed by another fondle and squeeze. The energy rises higher. Two or three more slaps and tickle, fondle, squeezes and the intensity of the energy it has awakened has become unbearable. An irresistible force has burst out from my balls and is exploding inside me. I have an overwhelming urge to do exactly what I do next and nothing else. Not to pull off my clothes and fuck Janine or have her suck me off, or to do anything that includes her. I jump up and march to the other side of the room, unbuckling my belt and pulling down my zipper in a frenzy as I go. I am muttering, "I'm sorry, I can't help myself." And really I felt there was no choice at all involved. Across the room sat a large armchair. Tearing down my trousers and underpants, I plump myself down in the chair, grip my already stiff dick tighhtly, and start pumping it feverishly. I am grunting loudly as I do so. This is the opposite of my usual teasing, ease to orgasm. It's intense and urgent. As I pump and grunt my hips are thrusting like a piston. It doesn't take me long to cum. My orgasm is an explosion of raw energy that bursts out of me in thick spurts of cum and a loud roar. I sit there after, panting and dazed. Janine hasn't moved from the sofa. She is staring at me and her eyes are really big. I shake my head and say,"I dunno what just happened. Your spanking and touching my balls triggered something wild. I just felt taken over by it." She said, "Yes, that was really weird. And the weirdest was while you were pumping your dick it seemed to grow huge and fill up all the space in front of you. It looked like the dick of that characterr in my dreams."
