"I think you should go first" Mark finally answered. "You bought the body suits, so you should be the first to try them out." Mark was also leaving out the part about him not being so sure of the technology used, or the fact that he was interested in what kind of sex him and Jess would have with her in the suit.
"Ok" Jess answered back, rather excitedly. "Now the instructions said that the process takes a few minutes, so your going to have to wait out here. I already made some food for you in the dining room, and the TV is yours until I am done." And with that Jess skipped happily to her bedroom to get ready. Mark had to laugh to himself. Jess was always the best girlfriend he ever had, so doing anything to make her happy always made him feel good. Now she was so happy she was skipping down the hallway, and Mark knew that even if the suits didn't work as good as the TV said, they would still have a good night.
Jess quickly entered the bedroom and pulled her suit out from the bag. She then went step by step in putting everything on. First she took off all of her clothing and put on the special skin rub and sealer. Next came the skin suit, which acted like a body spandex suit that covered your head too. Making sure her parts were lined up, and that all of her hair was sticking out the top, she moved on. The next thing was the penis, which was a little strange to her. Following the directions, she took a bottle of slime like goo and squeezed it's contents into her pussy. Next she inserted the strange dildo like side into herself until it seemed locked into place. Almost done, she took some pads and wiped down the entire suit and penis. And finally she took the pills that came with the box, hooked up the small electronic device to the small contact points, and laid down on her bed.
As Jess laid there, she could feel everything start to work. First was a numb sensation that went through her entire body and made it so she couldn't move. Next she felt tightening and pressure all over herself, but no pain. For a minute her eyes lost focus so she just closed them and concentrated on the changes. After what seemed like 15 minutes, the pressure began to subside, and she slowly began to feel her limbs again. Following the directions, she waited another 5 minutes until she could feel everything, before she removed the small devices clamps from what now felt like her skin. Free from the device and able to move again, Jess decided to go to her bathroom to see the changes for herself.
Jess slightly stumbled off the bed, adjusting to the new body, and made her way into the bathroom. When she turned on the lights, she was greeted with a surprise. Looking back at her was indeed a very young and girl-ish looking boy. Jess had made her suit so she would look like she did when she was 15, but with a few changes. First was that she now had a flat, but slightly muscular chest. Her shoulders were slightly broader, and her hips were slightly thinner. And finally there was the 5 1/2 inch erect penis that now signified that she was for now a "he". Jess reached down to touch the new part and was surprised to find that not only could he feel it, but that it felt really good.
Jess looked at himself a little long, touching and feeling around his new form, and then got back to work. Wanting to complete the illusion of being a very girly boy, Jess had pulled out some of his old clothing that "she" wore back when he was 15. Putting everything on, adding some make-up, and stuffing the bra, Jess now looked just like "she" did when he was 15. Happy with the look, Jess headed out of the bedroom to where Mark was in the living room.
"Hey there sexy" he called to Mark. Mark turned around to see a younger version of his girlfriend before him. "Wow, I though you said you were going to make yourself a guy, not make yourself look younger." "Awwww" Jess started, "but I am a boy right now. Just like you wanted, I am the most feminine boy you can find. Oh, and for now, call me Jessie." He ended with a cute smile while looking at Mark.
Mark was still a little stunned, as he was having trouble believing that his girlfriend was a boy, and not just younger. So to cast away doubt, Mark got up and walked over to Jessie. "Mind if I check things out?" "Go right ahead" Jessie said, still smiling. Mark pulled Jessie in and started caressing his body. Mark first noticed that Jessie felt just a little more muscular, and a little less soft, but not by much. Next Mark found Jessie's bra was stuffed, and with one hand confirmed he was now flat as a board. Finally Mark went in for the last piece of proof. With his other hand, Mark reached under Jessie's skirt, pulled his panties to the side, and felt Jessie's still very erect penis.
Stepping back, Mark could not believe how much the suit had changed his girlfriend. "So" he began, "you can feel everything I touched? And everything I touched is real?" Jessie nodded. "Okay, so what do you want to do now? I mean, I am kinda interested to see how you look without those clothes on. But at the same time, we don't have to rush since we got the whole break. So, what to do? What to do?"
