Jon let Karyn continue to play with his clit for a few minutes. He could feel the heat and moistness radiating from his crotch. His eyes were closed so he could better concentrate on the new feelings. Karyn stopped stroking his clit for a second and it seemed like she was trying to push deeping into Jon's pants but, even unbuttoned, they were too tight.
He opened his eyes for a second when he felt Karyn tugging his pants down. He knew that if he was going to put a stop to this, this might be the best time, before they went too far. Instead of stopping though, Jon lifted his hips off of the couch to make Karyn's job easier. He was a little surprised when he looked down and saw that she had removed his underwear as well. Any concern that he may have had dissolved instantly when she put her head between his legs and started eating him out.
Jon's first orgasm with female genitals came soon after. He lay back on the couch breathing heavily in a post orgasmic haze. He felt Karyn moving around then she was sitting next to him on the couch again gently caressing his breast and kissing him.
When his breathing was closer to normal he felt Karyn take his hand and pull it gently down to her crotch where he discovered the at some point, she had removed her pants as well and was as naked as he was. Jon knew that this might be his last chance to slow things down. He also knew that slowing down or stopping weren't what he wanted anymore. He wrapped his hand around Karyn's new penis and began to gently stroke it up and down. He knew that previously he wouldn't have wanted to touch somebody else's penis but, with the changes brought on by their wishes, being attracted to a woman with a penis while he was on the female part of his genital cycle was normal.
Jon quickly discovered that it was awkward stroking somebody else's penis and he briefly considered using his mouth to get Karyn off the way she had for him but, even though he was attracted to women with penises now, he wasn't ready to give anyone a blow job. It didn't seem to matter too much to Karyn though, she was beginning to buck her hips in time with his strokes and she seemed to be enjoying his ministrations.
Jon was trying to decide whether he wanted to try finishing Karyn off with his hand or take things further when he spotted her purse out of the corner of this eye. It was only a couple of feet away sitting on the coffee table and he could see one of the boxes of condoms poking out the open top. Seeing the condoms, Jon made up his mind. He continued to stroke Karyn's penis with one hand and grabbed one of the condoms with his other.
Jon had, of course, worn a condom the few times he'd had sex previously and, he realized with a shock, his wish provided memoried told him that his girlfriends had on the two occasions he'd previously had sex while on the female part of his cycle. Those memories weren't really helping him now though: he was having trouble getting the condom out of it's package.
Apparently Karyn had noticed that his attention was divided because she sat up to see what he was doing. She laughed slightly and took the condom from him and opened it without any trouble.
"I loosened it for you." Jon said
Karyn just smiled as she rolled the condom onto her penis.
Now that it was clear that they were both ready to go all the way, they came together with renewed passion. They didn't stop until hours later when they had gone through all of the normal sized condoms that Karyn had bought at the store. They might have gone on even longer if the larger sized ones had fit but they were disappointed to discover that, though her penis was good sized, the large condoms were too loose and would not stay in place.
They lay together on the livingroom floor having long abandoned try to contain their lovemaking to the couch. The room reeked of sweat and sex and their were condoms and their wrappers scattered all around the room. It was getting late in the evening and the two young lovers were half asleep when sound of car doors slamming alerted them that Jon's family was home.
