Series one: Christmas eve

It's late on Christmas Eve but, unlike in the famous Christmas story, there is a creature stirring. Three of them in fact. Sis, Abby and Uncle Timothy.

"Merry Christmas Abby," I coo in my niece's ear as I lift her from her basinet. She immediately stops her crying and smiles up at me. "Mommy will be here soon honey," I promise as I offer her my finger. She's just realizing there's no milk in it when her mother comes through the door.

"And Merry Christmas to you too," I say as I pass my niece over to her mom.

There's no shyness in her movements as she quickly lets her negligee slip off her shoulders. No artful adjustment of her clothes as she brings her hungry child to her chest. "None for you tonight," she promises me but I can see she's happy I'm there. Happy that I'm looking at, and admiring, her body.

"No time anyway," I answer as I pull my digital camera out of the pocket of p.j.'s.

"No way, don't you dare," she says the second I aim the camera at her. Abby, her face buried in her mother's bosom, ignores the flash.

"TIMMY!"

Ignoring her I walk over to the light switch and flick on the overhead lights. Then I turn on each of the three reading lamps in the room. "We won't need the flash now," I tell my sister as I start to photograph her.

"Don't. Pleeeease Timmy," she says as she attempts to cover the breast Abby isn't feeding on.

"Smile," I order as I lift her hand away from her body. I continue to snap pictures.

"What if someone comes?"

"They're all asleep," I answer.

"We shouldn't," she says but she belies her words by arching her back while cupping her breast.

"Christmas milk ... Christmas breasts ... Christmas baby," I say reverentially as I continue to shoot. "We'll make our own Abby and Emily album."

"No one can ever see them," she orders as I, finally finished shooting, put the camera back in my p'j.'s pocket. It bumps against my raging cock.

"Except us."

"Don't even let Gretchen see them." We both know that request is an impossibility to meet given our sister's curiosity and her mastery of computers.

"I'll take some more, next week, during the day," I promise.

"It's wrong," Ems insists but we both know we're going to do it. Neither of us has done anything near as exciting in our whole lives. And as I stand I know she can't help but see my erection poking straight out. The thin cotton cloth of my p.j.'s can't hide its need.

I stand still in front of her and wait until her eyes zero in on my rearing mast. Finally she tears her eyes away and looks up into mine. "Merry Christmas," I whisper as I bend down and kiss her. A quick kiss, but not a brother's kiss. A wet kiss.

"Merry Christmas," she whispers back when our lips break apart.

"And you do know what I want you to give me for Christmas don't you?" I ask as I back towards the door.

"I caaaan't. You know I can't," she pleads to my back as I disappear.
