Eric entered some settings. Having this curvaceous body had drawn out some ideas for a change. Lisa re-entered the room a few seconds after Eric finished and hit enter. "Get ready for this, Lisa." He set it so Lisa would change first, so she'd be surprised. Lisa sat on the floor, but started fidgeting. She had a weird feeling in her crotch. Due to the breasts and thighs in her way, it was difficult to investigate. She started to feel a bit horny. "What is this?", she wondered. She pushed her breasts apart and spread her legs, to find a dick. A dick, with a pair of testicles beneath it, had appeared in between her legs. She let out a small shriek. Eric laughed. "Hey, this isn't fair! You already have a dick!", said Lisa. "Don't worry, my change starts when yours ends.", said Eric. Lisa watched her dick grow much larger, to at least a foot long. Her balls were both the size of baseballs. "Oh god...", she moaned. She turned to look at Eric and noticed his dick growing larger too. He spread his legs a bit to give himself some room. Eric moaned loudly. He felt a new feeling, an itch, located directly behind his balls. Lisa gasped as he noticed Eric's hair growing longer. His face looked a bit similar to his mother's, when she was younger. After the changes finished, Lisa was at a loss for words.
"I was kind of interested in being a woman.", said Eric, speaking in a sultry female voice. "This body's amazing, but I kinda felt bad about losing my dick. So I figured I'd change myself into a full girl, but give us both huge dicks." Lisa thought for a moment. "So... you have a pussy?" "Yeah. Want to try it?" Lisa got up and walked over to Eric, a bit bowlegged thanks to her new appendage. Eric sat down and spread his legs, and Lisa took her cock and pushed it behind Eric's testicles. Eric let out a moan. Lisa, still a bit inexperienced to the whole male genitalia thing, kept pushing into him. Thrusting and thrusting, Lisa quickly got the hang of it. Eric's dick was getting harder as he was fucked. Lisa quickly leaned forward and started sucking it. It was too much for Eric, who was crying out through throes of passion.
After the two grew tired, they lied on the floor, opposite each other. "Eric..." "Yeah?" "Want to switch places?"
Once both had decided that they had had enough sex, Lisa wondered what to do. Continue the changing game, return to normal, or stay the way they were now for a while.
