Borrowed skin

by Alex · Oct 8, 2026 · second person

You're at home, going into your sisters room because of a bet you lost, the punishment being to steal and wear some of her clothes. When you're back in your own room with a pair of female briefs, you put them on and realise that your body is changing to match hers underneath the clothes.

Main character

An athletic college student back in his home town for vacation, staying at his parents house. Usually studying medicine and not having much time for social gatherings, he met with his friends from high school for a little low profile fun ending up in this situation. He has an athletic body marked from playing volleyball, short brown hair and piercing olive eyes.

How it opens

The bet was simple: last one to blink at the staring contest had to get some female clothes and wear them for a full hour. You lost. You always lose. So here you are in your own room, door locked, holding a pair of Laura's briefs like they're live ordnance, feeling exactly as ridiculous as you deserve to.

You put them on. That's when it starts — a warmth blooming across your skin underneath the briefs, a deep structural ache like the feeling of a limb waking up. You look down as you feel a pull and see your penis pull back towards your body. A sudden pop as your pelvis widens and your lower waist pulls inward. You grab the briefs pulling them forward just in time to see your crotch flatten and your balls pull into your body with two small pops. Then a squelching sound sets in and you feel a parting as the outer lips of a vagina appears.

Downstairs, the front door bangs open. Laura's home early. You look in a mirror mounted on your wardrobe, recognising your lower silhouette as Laura's, except they're your legs and body from the lower waist and up. You hear Laura walking up the stairs and have maybe four minutes to figure out what to do about it.

Setting

A suburban house in a rain-soaked town, present day. You lost a stupid bet and had to steal a piece of your older sister's clothing as punishment. Now, wearing it in your own room, your body is shifting to match hers from the lower waist and to the bottom of the pelvis— and she's due home within the hour.
