"Well" Jessie began "I am willing to do whatever you wish. But remember, I expect the same from you when we switch. Ok?" "Gotcha" Mark said while nodding, "Then shall we continue in the bedroom?" Jessie just smiled, grabbed Mark by the hand, and lead him to the bedroom.
Once there, Mark began again, "So lets see just how much you have changed." And without anymore words, Mark began to strip Jessie of his girl cover. Finally Mark had Jessie completely naked, and he was very surprised. While Jessie looked a lot like Jessica did when she was 15, Jessie still looked boyish enough to not be completely mistaken for a girl once naked. Mark was also a little surprised by the fact that all of this was making him hard. He was actually looking forward to experimenting with the little boy who was, not but 30 minutes ago, his girlfriend.
Mark then decided to just go with it, and removed his clothing as well. After all, boy or not, this was still his girlfriend Jessica. Mark picked up the boy and laid him on the bed. There Mark moved over Jessie and began kissing and touching him. For Mark, it was just like kissing his girlfriend when she was younger, but slightly off at the same time. For Jessie, he was enjoying everything as a boy, and couldn't wait for things to get heavier.
After a few minutes, Mark began to move down Jessie's body, stopping briefly on his chest. Mark teased and kissed Jessie's chest and nipples just like he would have done with Jessica, and then he continued to move down further . Upon reaching Jessie's rather erect package, Mark felt a slight hesitation, as he had never done anything with another male before, even if this was actually Jessica. However, he had already gone this far, so there was no turning back.
Mark came down and wrapped his lips around Jessie's penis, only to find that he actually kind of liked the feeling and taste. Mark slowly began to work Jessie's young shaft while Jessie enjoyed his first blow job as a boy. Mark found himself moving faster, and going deeper, as he was now happily giving his girlfriend turned boyfriend head. It wasn't long before Jessie felt a building from his crotch and started lightly moaning in a girlish voice. Finally with a few thrust, Jessie released his seed into Mark's mouth. Mark being surprised by the sudden salty explosion decided to just swallow without much thought.
When it was finished Mark came up and looked at Jessie. "Hey, just how real is this suit? I may have never done this before, but I think you just came like a guy." Jessie just smiled before replying, "Well yeah, I got the most realistic suit the store had. It said that within 30 mins I could start producing male cum, and if you look at the clock, you'll see it's been 45 mins. Now, lets try something else." And with that, Jessie flipped over onto his hands and knees, exposing his ass to Mark.
Mark, now being back in a sexual area he was use to, needed no further explanation. He grabbed some lube from Jessica's night stand, and rubbed his now extremely erect member. Finally Mark placed his penis at Jessie's hole and easily drove in. "Wow, your a bit looser than I remember." "Yep" Jessie giggled, "It's another modification I made to make things easier for us." And without anything more to say, Mark began thrusting deep into Jessie's rear. As Mark began to pick up speed, Jessie found himself not only pushing back, but also getting hard again from the new stimulus. Finally after a time Mark could hold back no more and released his hot cum deep into Jessie's ass. Jessie, who had started stroking his cock, also had another orgasm and sprayed a small load into his own hand. Curious, Jessie brought his cum filled hand to his mouth and tasted his own seed. Jessie was happy to find that Mark had not been lying when he said Jessie's cum was just like that of a normal guy.
Both Mark and Jessie, now exhausted, laid down on the bed to rest. Mark found himself happily holding the young, girlish boy in his chest. Looking down he noticed that Jessie now looked a little more boyish covered in sweat, with most of the make-up cleared off. However, Mark still found himself very attracted to the boy, but tried to tell himself that it was only because his girlfriend was still inside of Jessie. Jessie on the other hand found himself loving every feeling he just experienced, and feeling more like a boy than just a girl pretending to be a boy. And most of all, Jessie felt satisfied. Satisfied with being a boy, and making love to his boyfriend as a boy. He almost felt like he had found his real self, but choose to keep this from Mark for now.
The two laid there for awhile before picking up again. All through the night Jessie and Mark made love until they had nothing left. Finally the two drifted off to sleep, both looking forward to what the next day held in store for them.
