Sarah scrolled through the options while Jeff was in the bathroom. She found one labelled 'cuntboy'. She wasn't sure entirely what it meant, as there was no explanation beside each label.
'Weird,' she thought, and clicked on it, leaving the 'memory change' box ticked, applying it to Jeff's mind.
Jeff was pissing into the toilet, when suddenly a switch flipped in his mind. He looked at his cock, disappointed. He loved being a man; having strong muscles, a deep voice, and thick facial hair, but he hated having this long, floppy appendage between his legs. It just got in the way, he thought. When Jeff had sex with Sarah, he always thought she was enjoying it a lot more than he did.
Jeff went back to the bedroom, his dick feeling unnatural between his legs.
'Sarah, would you be fine with it if i changed my dick into a vagina?' Jeff asked. Sarah pretended to act confused.
'You want to be a girl?' She asked, knowing what he wanted.
'I just... feel like I was never meant to have a penis. I like being a man, just not this,' he replied, holding his flaccid cock.
'If that's what you want,' Sarah said, smiling. 'I love you, not whatever's between between your legs.'
Jeff went onto the Chronivac, changing his genitals from 'penis' to 'vagina', hitting apply. He felt a warmth overtake his penis, as it began to shrink. Jeff looked at Sarah excitedly as his testicles pulled into his body, leaving his scrotum empty. His shaft continued to shrink as his foreskin pulled back, his scrotum receding into his crotch, forming his new vaginal opening. Jeff came, forcing all the sperm out of his testicles as they finished their reconfiguration, becoming his ovaries. His penis shrunk back into his new pussy, becoming his clit. His hips expanded slightly as his womb formed inside him, completing his transformation.
Jeff stood there in bliss, looking at his new pussy. His breath became shaky as he moved to touch his slit, sending a jolt of pleasure through his body.
'I love it,' Jeff said to Sarah, giddy.
'You look good like this, babe,' Sarah said. 'Your ass is bigger too!' Jeff turned around; there was more mass down there than usual. Jeff pulled his underwear, which had become a pair of black panties, back up his legs. He had no bulge anymore, and the feeling of cloth touching his sensitive opening made him aroused, as he felt an strange wetness between his thighs. Despite the unfamiliarness of his new pussy, it felt way more natural than having a penis; it just felt right.
Sarah kissed her now dickless boyfriend, putting her hand down his panties.
'Let me show you how it feels like on our side,' she said, voice filled with lust. She began to rub his clit, making his legs go weak as he fell onto the bed. Sarah pulled down his panties, exposing his dripping pussy as she inserted a finger into his slit. Jeff gave a feminine moan as his pussy continued to drip onto his bedsheets.
Sarah continued to fingerfuck her boyfriend until he climaxed, his pussy spasming as he experienced his first female orgasm. Jeff screamed with pleasure, Sarah grinning as she watched her boyfriend suddenly understand how it felt.
'That was incredible,' Jeff said, out of breath. 'Does it feel like that for girls every time?'
'Why don't you tell me,' Sarah replied, kissing him as she began to rub her pussy against his.
Jeff was in utter bliss as he thought about what to do with the Chronivac next, now that he had finally achieved his fantasy.
