They take your cock

The girls talk amongst themselves for a while, giggling and admiring each other's changed appearance, leaving you to stand awkwardly on display. You pull a bit at your now ill-fitting clothes in a fruitless attempt to cover up. Your new breasts and wide hips are particularly obvious, especially paired with your short stature and feminine features.

Your new assets seem to be attracting a the gaze of many men in the market. They don't seem interested in your wares, just in roving their eyes over your transformed body. It fills you with an uneasy feeling you aren't yet familiar with.

The girls look like they're about to move on. You let out a soft sigh of relief, thankful for the swaps with them to be over. Once they move on you'd have a chance to swap away some of the features they gave you for a few more coins, hopefully enough to get back to where you started.

The lead girl must have noticed your relief, because she turned back with a mischievous look in her eye. "What's got you in a good mood?" She asks you suspiciously.

"Uh, nothing." You protest with your sweetly high voice.

"Probably relieved we didn't give him a pussy." The girl who took your height says with a lecherous grin.

The lead girl strokes her chin with a twinkle in her eye. "Well I hadn't intended to buy a penis at the market today, but now that you mention it we haven't even inspected the goods." She ran her hands along her new hips, the ones that had been yours until moments ago. "I doubt it's even safe for me to get pregnant with such boyish hips. I'd be wise to swap away the risk."

The girls look up at you expectantly. You feel a compulsion rush through the collar. Your slender hands seem to move on their own as they remove your trousers and undergarments to give the girls a clear view of your remaining manhood. A deep blush reddens your cheeks as you notice others in the market craning their necks to get a good view of your display.

"Oh, that doesn't look too bad." The lead girl says with a smile. "I was worried he might be too big, but I think I'd enjoy having a cock like this." She reaches out to inspect you, your collar glowing for a moment as it suppresses your ability to stop her.

You simply stand there on your podium, hands behind your back, while you feel her tug on your member and cup your balls. You can hardly see what she's doing thanks to your new breasts blocking most of the view, but you get the sense she's moving your dick around to get a good look at it.

"Don't forget to see what it looks like hard." The newly-tall girl suggests, a perverted smile still on her face. You really wish she would stop giving the lead girl ideas.

"Well let's see it then." The girl handling your penis tell you. "Make it hard for us." You're about to explain it's not that simple, when you feel a tingle run down your spine from the collar. The girl releases your member as they all stare at your growing erection.

"What do you think girls?" The lead one asks, beginning to handle your penis again. "If I had one like this would you help me play with it?" She pumps your cock a few times, sending shivers through you. All the other girls respond with enthusiasm, egging her on. She looks up at you, hand still around your rigid dick. "Your crotch for mine, 100 gold." She offers.

Your face pales, that's more than all the other trades so far combined. You consult the paper and to your relief find it's still not enough. You barely shake your head before she makes another offer.

"Fine, 200." She says, rifling around in her coin purse for the funds. You feel a chilling tingle in the collar, the compulsions to accept her offer are setting in.

You open your mouth to refuse, but you can't quite make the words. Looking back to the paper you can see she's met the market price exactly. After the 25% cut you won't even have enough money to buy it back at market rate. Before you'd even realized what you're doing you find yourself nodding your head, accepting her offer.

The girl plonks down a pile of coins on the pedestal and lets out a little sequel of excitement. "I can't believe I really just did that. My very own penis! I'm gonna practice writing my name in the dirt the next time I need to pee. Ooh, I wonder what it would feel like if one of you sucked on it?"

She paused talking for a moment as the tingling swap feeling passed over you both. You look down in disbelief at the new mound between your legs. Every inch of you has become feminine, and now you have the sexual organs to match.

"Oh, my period was about to start any day now, so be sure to line your underwear with cloth." The girl who has taken your dick informs you. She pulls a rag from under her skirt and drops it on the podium for you, then leaves to catch up with her friends.
