she must be fucking crazy if she thinks so...

You deny "fuck you i won't beg to get fucked!"
she smiles teasing your cock even more. then suddenly she starts slaping it roughly making you scream in pain
"stop, stop that!"
"don't worry sweetie, son i'll stop"
then she continues spanking your cock till it returns to it's usual size
once she's done it she goes to the kitchen where she gets something from the freezer
once she comes back she gets your cock spanked again and once it's reduced again she gets it around your cock
"it's a flexible wrap, that will get reduced as your cock do... but will never grow back to it's usual size. staying in the freezer, right now it must be very cold, so it will make your cock get reduced to it's mínimum size... well from now on since you don't want to beg for it's use that will be it's size... what a pity it may attempt to grow and it will hurt then , isn't it?"
