Jenny was in a state of euphoria, every thing was on fire and it felt absolutely wonderful. Abigail was feeling similarly, nothing had ever prepared either of them for the feelings and emotions that were cascading through them at this moment. Both of the former girls now had some semblance of a penis and they were working them as much as they could. Jenny could almost swear that every stroke of her new cock pumped more power and strength into her limbs.
As she continued to stroke she noticed other changes occurring in her new body. Her breasts had already started to deflate from her original gain in muscle, but now they were shrinking into her chest quickly. Deflating and become a set of pecs...a fairly nicely shaped pair of pecs she noted with some pride. She wasn't very muscular yet but she was definitely taking on the lean tone of a healthy male. The room itself started to fade as she continued to pump, images of strong men quickly fading away as images of hot girls took their place in her mind. The idea of sticking her cock into a nice, warm vagina was so very appealing to her now...giving her such a rush that she began stroking even more fervently. No matter how hard she tried the pleasure seemed to be stuck at this level though.
Suddenly though, the pleasure intensified and Jenny could have wept with the wonderful sensations it brought her. As she stroked she noticed something new forming at the base of her enlarging penis...her new balls were now slowly inflating...descending down into their proper place on her new male anatomy. And with them came a crop of dirty blond hair, starting to grow thicker from her pubic area. Before she had been nicely shaved but now it was growing at an insane rate, all over her new balls and upwards towards her belly button where it left a thin trail noticeable. In addition, a few hairs slowly grew next to her nipples, which had now decreased in size.
Her arms grew thicker, bulging with lean muscle as something in her mind clicked into place. After that final piece had been arranged she noticed a build up of the pleasure she had been feeling, and it slowly started to build and build until she couldn't hold it any longer. With a couple of deep grunts in her new tenor voice she came, releasing a thin stream of seed from her new penis.
As she collapsed down in a slowly growing awareness of what had happened she noticed that where Abigail had once been a teenage boy about her age was now collapsed onto the ground, still furiously mastrubating...until he as well came in a much deeper voice than what Jenny now possessed. In addition, Jenny noticed the boy (Abigail he guessed) was his same height, but definitely thicker. He had quite the developed muscles for someone his age, Jenny would have guessed him to be a football player if she had seen him at school.
As Jenny looked up, he quickly noticed the two other girls standing in front of him...and then he became very well aware of his new male anatomy and his nakedness in front of them.
