The Reindeer's Present

 "Ooo's a lucky boy, den? Mistress 'as made oo a lovely lil' Christmas present.
 Now Mistess Tatyana an' I are gonna go back into our nice warm house an' eat our pipin' hot Christmas dinner while oo is gonna remain kneelin' there an' open your nice lil' prezzie. an' if oo 'asn't unwrapped it by the time we've finished our pud, Mistress is gonna be wery disappointed and oo is gonna get a wery bad whippin' for not pleasin' your Mistress!'
 The two women stepped inside the warm confines of their house without looking back.
Tatyana was convinced that the package would still be tightly wrapped when the returned to him, despite the fact that the damp snow was already saturating the wrapping paper. This only made her even more curious about contents...
 "alright, spill the beans - what's in the Christmas box for shit-head out there?'
 "It's a surprize."
 "Pleasant or unpleasant?'
 "For him? VERY unpleasant!'
 "Do tell."
"You know that 3D printer we bought last month?'
"The one in my office?'
"Same thing. Well while you were away last month I got him all hot, bothered and erect and then I used it to scan his cock and made a 3D replica, but one with a flange at the base and a scaled up diameter...."
 "Right, so his Christmas present is a model of how you think his cock should be?'
"No, because I then made a casting of the model to make a mold from which I made a copy out of clear polyurethane - rather like those clear paperweights that were all the rage a while back. You know, the ones you could make at home and put sea shells and dead insects and things inside.."
 "So what's preserved inside this clear plastic model of his cock?'
 "Apart from the screw fitting so you can fit it to a harness or attach a pony tail to it?'
 "Yes."
 "Just the keys to his cock cage - The ONLY keys to his cock cage. From now on he's going to be walking around knowing that the only way that cock cage is coming off is with the aid of some bolt crops and until that day comes along his back passage is going to be stuffed and stretched by the only hard-on I've ever let him have."
 "You're evil."
 "Merry Christmas."
