You can't help but to gravitate towards the large black cock. Maybe it is because you feel realy small right now, but the idea of getting really big one is just too good to pass.
You need two hands to actually grasp the penis, sof it as big as you used to be erect. "I'm going to try this one!" You tell Mia excitedly.
She doesn't seem to share your excitement. Mia look at the tiny balls hanging underneath the large cock and looks unimpressed. "Are you sure? It feels small where it counts?"
"Yes! I know the balls are small, but I still have large ones, they are just going to ad up to mine."
"Sure thing. Just don't keep your expectations too high, I know you want to ger rid of your tiny dick, but experience tells me that dicks too large aren't that fun to play with."
You hear Mia's advice but you don't actully care for her words. You can't stand the idea of having a micropenis and you want to fix it as fast as possible. Maybe you are overcompensating, but who cares?
You don't take your time and attaches the black cock just above your tiny dick. You notice the balls fuse to you ballsack. They don't look like they add up to the volume of youe balls, it's like they're not even there, but you can feel them.
You touch your new penis and can feel the whole sensations as if it were always part of you, albeit it is from a complete different color. Mia give you a horny look and go straight to play with your new cock. "I tought you didn't like large dicks" you tease her. "Well, a cock is a cock." She smiles with the new toy in hands.
Before you new penis got even half erect, your old one is already at full mast, in all its less of impressive 2 inches. You original cock is jus dwarfed by the black cock on top of it. As Mia keeps jerking you off, you feel like you dick can still grow more.
Your new dick finally hits its 12 inches, but it still feels like it's fully hard. Mia starts to beat you off even faster causing you dick to grow eve more. You realize that the black cock is turning a light brown, you notice that your original cock is completely vanishing, leaving you with only a 14 inch brown cock. Mia doesn't seem to care the tiny dick at all. Neither does you, you have a large cock now.
You are starting to get light headed, but your dick is still not fully hard. Mia still didn't quite gave up of making you get there. You're getting to 17 inches now and you almost passed out when feel yourself finally cumming. There is almost no semen to be seen.
You look down to see a penis the same color of your skin it is almost at 19 inches, although it is starting to get soft. You balls have almost vanished, they are the size of peanuts now, and you can only feel a single pair.
Mia is less then impressed, she seems annoyed even. "See! You almost passed out. And now you don't even have balls. You should just get rid of it."
"What? You want me to go from dicklet to dickless?"
"Well, it was your call to go for this lousy dick. Besides you're not getting dickless, we have a whole box."
You sigh looking down at your monster dick. It really wasn't the best idea. You decide to remove it and put it back in the box. It feels weird having nothing between your legs, but you do have a box filled with other options.
