"Fine! I'll take the chance and show you who is ballsy!" You say with newfound confidence.
"After the coin toss is definitely going to be me!" She teases you further.
A 50/50 chance seems good enough to you. You give another quick glance at the large bulge in her pants. You might end up loosing your balls, but the chance of going home packing a larger cock was too tempting, after all that is why you went up the stage in the first place.
Jenny prepares herself to flip the coin. "Be ready to hand me those balls!" The way she speaks with confindence just warns you that there is something off.
"Wait!"
"What? Are you going to chicken out again and just hand me the goods?"
"No, I just have a coin here and would feel better if I tossed it." You say flustered after her remark.
"Fine by me. Just suit yourself!"
You toss the coin in the air. It seems to flip for an eternity until it finally hits the ground.
Heads.
Yes!! You made it! You managed to swap your dick size with her.
But there is something wrong. You look at her and she doesn't seem too fazed, in fact she kept the same smug since the beginning.
"Guess I'll have to keep my word. Here I have portable swap device with me." She attaches a cup into your 4 inch cock. The she pulls down her panties to attach the device on herself.
A big roll of paper falls flat in the ground, revealing a small 1 inch cock just underneath. Your 1 inch! She didn't even have a penis when she went up stage. You've been had all along!
You feel your cock shrinking down to just an inch with your eyes full of water. Of course she didn't care for the coin toss result, you feel so dumb!
"Yes!! A real cock!" Jenny swings her new manhood in the air. "It's not that big but is a real dick and is mine!"
She gives a kiss in your face and hand you the paper roll. "In case you want more volume down there."
You look at her so humiliated.
"Don't look at me like that! I kept my word."
"Let's do like this. Final offer no swindles. You give me the rest of your dick and your balls and I'll give you my pussy." she looks at you inquisitvely. "C'mom! Better go all the way than stay a dicklet. What do you say?"
