It felt like the best orgasm that Jack had ever had. Every muscle in his body was twitching as his cum shot out over his hand dripping onto his legs. As he slowly caught his breath he looked around. Nothing seemed different, he was still holding his engorged dick in his hands. Had his wish not worked? Jack sat confused, he had made the wish though so why had nothing happened? Just as he was giving up hope he felt it, a slight twinge in his balls and dick, like they had pulled upwards very quickly. He looked down, his dick seemed slightly smaller but then his erection was going down. Was it really working?
Jack watched and waited, then he saw it again, a slight pull on his balls and dick. It was like an erection in reverse. Spreading his legs wider he reached a hand down and cupped at his balls. They seemed different, as his hand touched them they pulled again, and again. Jack's eyes widened in anticipation. Slowly his balls we shrinking, it was not long until all that was left was a loose flap of skin. He pulled at the skin and as he did so noticed that it was getting tighter. The skin slowly got tighter and tighter until he was left with just his dick sticking out. There was a bit of freedom to not having his balls dangling between his legs, and it turned Jack on.
Minutes passed and everything seemed to stop, what Jack didn't realize was inside things had changed, and now it was beginning to show. His hips were getting wider to accommodate a womb, below his dick he felt something changing. A vagina slowly opened up, hair quickly forming around it. Jack took his hand away from his dick. Still covered in cum he touched at the strange gap he now had. A wave of pleasure shot through his body. Slowly he slid a finger in, as he did dick pulled at him. It was like his erection was getting sucked back into his body. He could still feel it but it was moving inside him now. It did not matter though because the waves of pleasure were building, Jack's cum covered hand moved quicker and quicker. His new vagina responded becoming moist. Moving his hand to where his dick was he realized it was about half its normal size, then a quarter. Then it was just the tip. It still felt hard to him but the sensitivity hand increased ten fold. Still moving his fingers in and out Jack moved his other hand down and touched his new clit. The pleasure mounted beyond belief and he had his first female orgasm.
