Series one: Late at night

"She let you didn't she?" my little sister demands. She's again burst into my room without knocking. I'm watching another lactation video. How does she know I wonder to myself as my suddenly blushing cheeks give me away.

Gretchen has just got home. If she'd been a half an hour earlier she'd have caught me photographing Emily. We'd actually taken the pictures in Gretchen's room due to the sunlight that floods into her south facing room in the afternoon.

On Gretchen's bed. Emily, naked, feeding her daughter. Then, with the camera mounted on a bedside tripod we'd taken pictures of me drinking from my sister's breasts. And then a video.

"Let me what?" I try to ask innocently.

"Milk her."

"I didn't."

"Hah! Liar."

"Even if I did it was just so I'd know what it's all about. For when I'm a doctor."

"Yeah right. And I saw your pictures mister smarty."

I'd known she would. Gretchen was our family's computer genius. Whenever anyone of us had a computer problem she fixed it. She knew our passwords. And Gretch was nosy. Over the years I'd come to accept that anything I did on the computer would be eventually be discovered by her.

So why had I downloaded the breastfeeding pictures from the other night to my computer?

"You did, didn't you," she asks insistently. I nod yes. "Perv," she accuses. I smile and wait. "What did it taste like?" she finally asks.

I ignore her question. "Will you let me when you're a mom?" I ask instead.

"Let you what?" Of course she knows.

"When you grow up. Marry. When you're a woman."

"I'm already a woman. And why would I let you?"

"You know why," I answer.

"If I did it would only because you gave me such a nice Christmas present." There's a promise behind her words, a promise we both know will be eventually delivered on.

"When they grow big that is," I add.

"They're already as big as the girl on your screen," she answers as we both turn to watch the milking taking place on my computer. Seconds later she's gone.

I start to download today's pictures. Gretch will discover them within days...

"We shouldn't do it every night. Besides, you had some yesterday afternoon too," Emily mock complains the second I sit down next to her on the couch. One of my hands has immediately moved to caress her long, flowing hair while the other seeks out the breast my niece isn't feeding at.

"You're beautiful," I answer as I lean over and find her lips with mine.

"You can't have any til Abby finishes," she orders when our lips separate.

"Yes mommy," I answer.

"And don't get an erection this time."

I don't address the erection question, instead I say, "Gretchen saw the pictures."

"What!" A shriek. I kiss my sister again. And the second she's got a sated Abby settled in her basinet I position myself on my back in my sister's lap. I lift my head and reach for the closest nipple.

"Not too much Timmy," she cautions the second I capture one between my lips. Her arm snakes under my head and supports me as I start to milk. My cock is harder than it's ever been and suddenly pops out through the slit in my boxers.

"Bad little baby boy," she says the second she sees it waving in the air. But almost immediately her warm palm closes around it.

"It's your turn to milk me," I say as her hand starts to slide up and down my glistening shaft.

This time she finishes what she starts. And by the time my cock starts jerking out my creamy sperm I've finished milking Em. My head is lying back in her lap, her breasts hanging ponderously above, and I'm groaning as I watch each strand of cum hurtle upward from the end of my prick. Then splatter down, most on my chest and stomach although one arches through the air and lands on Emily's cheek. She shrieks.

"Your turn," I finally say when the last drop of cum has been drawn from my penis.

"My turn what?" She knows! I wait. Finally one of her fingers dip into the pool that has formed around my navel. Slowly she moves the cream laden tip of her finger to her mouth. I watch as she tastes me. Watch when she looks up at me and smiles.

"It's good. Much better than--" But she stops before she mentions her husband's name. Then she lowers her head and trails her tongue down across my nipple and then starts to lap up my sperm.

I've never been as excited in my life...
