Josh discovered something that Christmas morning.
Just like a lot of thirteen year old boys, Josh had stopped believing in Father Christmas years ago. When he felt a hand on his mouth and opened his eyes in shock to see a man in a white beard bending over him - a man in a red suit with white fur trim whispering 'Hush!' he knew he had been wrong to doubt.
The old man was smiling at Josh, even if he hadn't taken his hand away. 'You've been a very good boy,' whispered the man, face close. 'And you will stay a good boy, understand?'
Josh nodded as best he could. For some reason, having a man in his bedroom and preventing him from speaking had made his little cock harden under the sheets.
Josh was ashamed of his little woodie but strangely thrilled to find Santa easing him out of bed - not moving his gag hand but simply placing his other hand under Josh's head and easing the child into a standing position.
The boy stood, head clamped between Father Christmas's strong hands, growing red in the face as he stood: his hard cock was tenting the front of his PJs but Santa didn't seem to mind. Santa chuckled, merely turned the boy away from him, released the hand behind the boy's head (still keeping the first one firmly over his mouth) and then took hold of one of Josh's wrists.
Smoothly Santa twisted Josh's arm up behind him, making the teen 'Mmmph!' in pain into the gag hand. At the same time, Father Christmas pressed himself to the boy's back, Santa's own erection pushing against the butt cheeks of the boy.
Santa steered Josh towards his bedroom door, a weird looking pair in the early morning light: a man in a red suit force-marching a boy with a prominent erection. 'We won't wake anyone,' whispered Santa into the boy's ear. 'Especially if you keep quiet.'
Josh tried to nod again, but Santa simply twisted the boy's arm higher up between his shoulder blades and squeezed his gag hand harder. In spite of the pain - or because of it - the boy's cock stiffened even more.
Josh was on tip toes as he walked, and understood they were going to his ten year old sister's bedroom. The door was open and even before being guided into the room, Josh knew Father Christmas had called there first.
Sammi looked up as the pair came in as best she could. She was hogtied on the floor by her bed, a groan deep in her throat muffled by the huge ball gag - red, just like Santa wore - that filled her mouth.
Josh gave a small whimper as he saw his sister, lying naked with her hands bound to her crossed ankles, elbows tied together, a rope at her throat running back to her ankles to ensure she kept her head up.
'Cute, huh?,' whispered Father Christmas as he kicked the door closed.
Josh didn't think his cock could get any harder, but it did. He nodded, even though Santa still had his hand clamped tight. Sammi, his precocious, pain-in-the-ass sister, looked wonderful.
'You remember, don't you, Josh?' asked Santa, not whispering. 'You wrote me and said what you wanted for Christmas.'
Josh nodded, relieved when Santa let go of his mouth, though not his wrist behind his back. 'Yes,' he gasped, voice low. 'I wanted Sammi all tied up for Christmas.'
'Right. "Dear Santa, most of all I want by bitch of a sister not to have a Christmas at all" That's what you asked for, what she's getting.'
Josh grinned, staring at the tightly bound pre-teen, wriggling on the rug by her bed. He had written a month ago, partly as a joke and partly in frustration when the little bitch had got him into trouble over something he hadn't done.
'You see,' laughed Santa behind Josh. 'I read all the letters. Trouble is, kids never ask for the right things. Toys, bikes, cell phones... hey, I'm an old man. I'm not made of money!' Another chuckle. 'But ask for something like this...'
Father Christmas paused, reached round the boy and flipped the kid's rigid dick out. Slowly, he masturbated the boy. Josh groaned, and his sister stared up making a strange gurgling noise, eyes wide in shock.
'You told me,' said the old man, rubbing Josh's cock. 'She's one little bitch.'
'Make me cum,' begged the boy, his voice a croak.
'You want to spurt, seeing the cunt all trussed and gagged?'
'Fuck, yes,' breathed Josh.
'Good boy. Can you spray her from here?'
'Oh... yeah,' gasped Josh. He didn't care about his arm hurting. Didn't mind the old man's iron cock pressing into his ass. He just wanted to enjoy this moment with his shitty sister all tied and gagged on the floor, where she belonged.
Josh came, his juvenile cum splattering across Sammi's trussed arms and head. One dollop hit her face and she made another strange squealing noise into her gag.
The boy collapsed on his sister's bed. It didn't matter what happened now. He watched, dreamily, as Santa carefully retied Sammi. The old man skilfully folded the ten year old into a small knees-to-chin bundle, arms behind her but bound high up between her pained shoulders. Sammi cried silently into her jaw-wrenching gag, and Josh enjoyed seeing that knowing she was hurting a lot.
Santa lifted the bound bundle into his sack, pulled it up around the girl and sealed the tie-string, before slinging the barely twitching bag over his shoulder. As if it was as light as a soft toy. 'I have to go and deliver this little toy to another house. A man who still believes in Father Christmas, and asked for something special when he wrote me,' winked the old man.
Josh nodded and then learned something unexpected about Christmas: Santa's white pubic hair tickles when he comes in your mouth.
