Jon was really confused. What was Karyn thinking turning herself into a guy, a naked guy with a huge erect penis? And now she was fondling herself! Of course, she probably had never touched a guy's erection before, so the attraction was certainly understandable. Come to think of it, I've never touched an erection other than my own and Karyn's was really really interesting, not at all like his own had been. "Karyn will understand," he told himself as he timidly reached out and grasped the knob of Karyn's erection.
"Gawd it felt so huge!" Jon could see that Karyn's large male hand completely engulfed the shaft, but in his slender little female hand it was like nothing he'd ever felt before! It was hard to describe, it just felt really really interesting. Jon knew that made no sense, but it just did.
Karyn took a sudden shuddering breath at Jon's touch and released her own grip. One look at Jon, and you'd think he'd just discovered the Holy Grail. He was nearly mesmerized. Karyn's smirk was converted to another gasp as Jon shifted his grip.
Sliding his hand downward when Karyn removed her hand, Jon gripped Karyn's shaft, or at least as much of it as he could. His fingers didn't fully reach around. "This was really cool," Jon thought as he gave Karyn's shaft a good squeeze, because it really wanted to be squeezed, Jon could tell that from the feel. Squeezing it revealed a fine ribbing underneath. In fact, Jon found that if he squeezed and moved his hand up and down, it made the most delightful thrumming against his hand.
Karyn was now nearly rigid in her seat and panting and gasping at Jon's every movement.
Intent on his own activities, Jon leaned down to better see what he was feeling. Seeing that he was really only squeezing and moving around the middle of the delightfully fun shaft, Jon loosed his grip slightly and slid his hand further upwards and onto the swollen mushroom head. Sliding his hand downwards again, required loosening and adjusting his grip, then it occurred to him that if it were slicker, it would be smoother. The only thing Jon had handy was spit, so he bent down a little farther and licked Karyn's knob to make it slicker.
Karyn was beside herself. Her thoughts a jumbled mess of: "Oh Gawd", "Yes", "No", "Faster", "Slower", "Oh Gawd" ...
The lick worked only briefly and Jon found himself having to lick it again and again to keep it slick until Jon simply put his mouth around the knob end and began sucking it like a sour green apple lollypop while working the shaft with his hand. It was fun to see just how much of Karyn's erection he could get into his mouth with each stroke and soon found that he could get a lot more of the huge thing in with each repetition. The base of the shaft was now Jon's goal as he tried to get closer and closer. Rise up and suck the head for all he was worth, and slide down toward the distant end so that maybe this time he could lock his lips around the base.
Karyn yelled and bucked incoherently.
Oblivious to Karyn's pulsing shaft, Jon headed back down toward his ultimate goal as Karyn suddenly gripped the back of his head as she bucked upwards and exploded, locking Jon into place at his suddenly acquired destination as Karyn cried out again and again with each pulse before finally slumping back and releasing Jon's head.
