Makes you hers (chastity)

Your limp dick now sitting there, she rebukes you a bit for not returning the favor. So, she goes over to the ice bucket for post-game muscle relaxing. She scoops out some and places it all over your balls. It's so cold it stings. Your penis starts to shrivel smaller and smaller. She leaves the ice on your scrotum and goes rummaging through her bag.

"I haven't used this since I got tired of my last boyfriend and kicked him out. But it did wonders for our relationship."

She pulls out a curved plastic tube with a locking mechanism on it.

"I'm sure it'll have the same effect on you."

She steps up and slides it around your now tiny cock and snaps it shut. She locks it shut, placing the key into her bag.
