It will be you who gets into a chastity device

The object she is showing at you is a chastity device. You look at Mike your best friend from the time you were children. He looks as scared as you
You look at the woman and you deny
"I'm not fucking allow you to get that thing in any of us, you bitch... so you" but, before you can continue, she slaps your face hard, making you shut up
"Well, not making a choice is also a choice, it's your turn, so you get it"
Then, she grabs the cage and, easily, gets it over your cock
It's an ellastic one, and feels very cold, making your cock shrink inside
She explains you what may happen "it adapts itself to your cock as long as it's for getting smaller. As your cock shrinks it may shrink too to keep in encaged, but as it tries to grow, it will stay on it's size, making sure it's unable.
For showing you its effects she gets naked right there.
She's some big tits, probably a D cup, and her round ass just get you even more excited. Your cock tries to grow in the device, but it's unable and it hurts like hell, making you scream in pain
She smiles "you see? this will avoid you from getting hard until i decide another thing"
Then she turns around giving you a very close to her ass and pussy what makes your cock hurt even more
"now it's your friend's turn"
