She turned and smiled at me. Her little hand was wrapped around my dick, just holding it. Picture after picture went across my screen, and I froze it on a teenage boy, naked, kneeling near the poolside. He had a tattoo on his shoulder and reddish hair.

"It's very pretty," Rebecca lisped, and giggled. I'd been showing her photos for four weeks now, on Saturdays and Sundays. Last week she had finally agreed to take off her shirt, and this week I had insisted she see my penis. Seeing one in real life was different than on the computer. She was fascinated by mine. She liked its hardness and warmth.

We kissed--something else new--and I stroked her flat bony chest. I said, "Next week I want to fuck you."

"Mommy said no," she told me, looking at the boy's picture. Her eyes were riveted to his moderate erection. It was a beautiful penis by any standards, plump and slightly curved, and exceedingly hard.

I often wondered how these models achieved their erections, as there was usually no sign of saliva or vaginal secretions on them, and when I masturbate I seldom get so hard. They had the hardness of a dream-state, the kind that comes upon you in the early morning just before sunrise, so intense almost painful that it wakes you and you lay there for a few moments savoring it, not even daring to touch it, just enjoying the pulse, the power. You wish you could hold that state forever. In a way, it's even better than an emission.

"Why no?" I asked her. I was so frustrated.

"Because I'm too young, silly!" she said. Her face was radiant, freckled, I licked her nose. God what beauty, what heartbreaking beauty.

"But you've seen all the pictures of girls and boys," I reasoned, "You know many of those girls are your age or even younger, right?"

She nodded. "They are naughty girls. Mommy said so. She said maybe I could suck your cock, but no fucking."

"I need to cum so bad, Rebecca," I whispered, my lips against her neck, nibbling, inhaling her girlish fragrance. She nodded. I think that meant, you can cum.

"I want to see more cocks," she said, and squeezed mine delightedly. She clicked on the slide show again. Sometimes I thought she was a cocktease.

The slides were arranged to show larger and larger penises. I wanted her to be comfortable with a big cock, like mine. I stopped the show when one of the fuck pictures loaded. It showed a Brazilian man with a cock at least a foot long, on his back, a young teenager sitting astride his pelvis, pushing herself down on it. The expression on her face was marvelous: astonishment, raw lust, an edge of fear.

"Hmm, he's huge," Rebecca said. "I like those big ones. Let's see more."

I had nearly a thousand photos in this file and after awhile I couldn't hold back anymore. I told her to take her hand off and I stood up, behind her, and jerked my penis a few times until I shot my load on her back. I rubbed the tip against her shoulder blades as I finished. She twitched as if I had tickled her. "Mmm, that feels nice," she said sweetly. Fucking yes that feels nice. Damn I wanted to fuck her.

She kept clicking the photos. She froze it on a man spurting untouched. It was a fast action still, and the bolt of semen appeared about six inches long, hanging in midair, tapered at the front and end, flared in the middle and spread, looking to my mind like a white leech or blind worm. The shot was from below and the model was completely tanned with a muscled chest, and he wore mirrored sunglasses. He had enormous balls.

"I have to masturbate," she told me, looking back and forth at the picture and my slowly withering cock. I nodded. She'd masturbated each time she'd been over, and I was hoping soon she'd do it in front of me, but she got up and went to the bathroom. When she came out half an hour later her face was flushed, almost red, and her hair was slick. She stank. She had put her shirt on. I tried to see the shapes of her little nipples, hard, crinkled. "I have to go," she said.

"Please don't," I said.

"Tomorrow, okay?" she said with a childish pout, a look of concern on her face. She was ineffably beautiful.

"Please ask your mother again."

She stood at my door and looked at me, her big brown eyes floating. "I'll see." She left.....(cont)
