Jim and lena were walking through a field, just finishing a night at the movies. They were both 15 and had been dating for 2 years. Lena's foot kicked something and she took her phone out to look.
It was a device with a small screen. Maybe I later she can figure out how it works. But little did she know she was about to learn firsthand. She pressed the button when she kicked it aiming on her boyfriend. As she picked it up she read "temporary infertile" what was this for?
Then before she could ponder anymore she felt the gun slip from her hands. Jim grabbed it to look closer and pressed the button.
"Why does it say sex machine? "Jim asked
"What? I didn't see that. I saw a bunch of settings though I wond_"she stopped as she felt a change.
She looked down and saw her legs grow taller. She became 5' 7 from her 5' height and then felt her whole body change. Her hips widened. Her arms lengthened. Her breast grew from measly As to EE with an ass to match. She was so entranced by the transformation she didn't realize she ripped her clothes in the growing process. She was like a porn star who had surgery but everything felt real and a part of her. Then she looked up to see a 6foot tan Jim looking like he exercised now,toned and sporting a 10inch hard on.
Lena couldn't look away. She had been horny before, but never have sex this instant horny! They'd only cuddled and felt each other up. They never had sex before, but this lust was too much for them. Jim laid her down on her back as the long grass grew and surrounded them. He couldn't hold back and went for her grabbing her hips. She moaned at this never being handled that way let alone naked and about to be penatrated for the first time. She was extremely and obviously wet. Her pussy, trimmed for some reason,dripped unto the floor. He aimed and went in all the way in one motion. She gasped feeling a real penis inside her. Her legs started to tremble. She grabbed his arm holding waiting for the next move. He pulled out causing her to roll her eyes and then he went back in. Slowly with each stroke he sped up. She clutched him and the grass for dear life. She came quickly never experiencing an orgasm this way. She could feel her body tense up uncontrollably. She could feel new muscles arching her back as she grinded back into her boyfriend. This was amazing. And then he kept going.
She started to feel horny again liking that this is hiw sex was. No wonder people love it. Jim breathing harder put one hand on her giant breast and then began to fuck harder. He was close to cumming and began to lose the battle. This was amazing. His girlfriend turned into a hot model or something and he was a toned bodybuilder. All this along with grabbing her tits finally cause him to cum shooting his seed into her for almost half a minute. "I love you lena" "I love you jim"
Then everything shifted back and they were thier normal selves and thier clothes were back as if nothing was stretched and turned up from ealier. She got up and laid down on her boyfriend as they shared a unique afterglow.
"That was.."
"Something else. Who knew adults had these"
"Babe i don't think this is a normal device. But I'm willing to try this again later..if you were okay with everything "
"I was Jim. You were great. But we gotta get home. That took up a lot of time haha"
They went home and decided to wait til tomorrow to test it. Jim's parents would be at work so lena could just come over. It was a miracle they didn't start having sex with how available it was.
When she came over she was wearing a cute tanktop n shorts trying to impress him. She brought up the machine and pressed once on her and once on him. Yes, we can do it again and not worry about babies or anyone. The she felt herself grow taller but not curvier? Her breast tighten up becoming pecs while her lower regions were reversing showing a penis protruding out more and more. Jim felt himself get shorter and then felt fat almost like everything filling up. He just wasn't used to having curves as breast came out and stopped at Gs. His ass was a bubble butt that matched Lena's but he or she had her own sexy look. Then he felt an urge in his new vagina. His fingers automatically went in and he gasped before falling over. He looked up at lenas body admiring it and now feeling a need for him to use it on her. No sooner had she felt that need to fuck again than lena grabbing her and aiming his dick in. It was 9iches devirginizing him as a female. Both were hormone crazy and fucked awkwardly but quickly. Lena not knowing how came early. Then they reversed back to thier old bodies.
"That was different. Warn me next time jim said.
"Sorry. Atleast now I understand why you look at me that way."she replied
Then she looked at the settings
