Steve Masters - Mom_s summer swap camp

Billy saw that he was close to talking her into it, and he continued in his most convincing voice. And it was easy for him to sound convincing. Shit, right then he would have given anything to see his baby sister once more sprawled out across her bed, fingering her lovely pussy.

"Seeing you like that before really turned me on," he said truthfully. "It turned me on even more than the book you were reading. And maybe… maybe watching me will turn you on just as much. Gee, Deb, it really sounds nice to me. I-I don't see what harm can come of it."

"And I don't either," Debby said, making up her mind. Her eyes drifted back to the impression of his now totally hard cock. "Ohh, Billy, it looks so big… so strong. You're right, I do get excited just thinking about watching you play with it. Can I… can I see it now?"

"If I can see what you've got?"

She nodded, but even as she spoke she was unable to take her eyes from the bulge.

"It's a deal," she said. "Mmm, Billy, I'm so excited. Let's do it right now. We've… we've got to be careful so we're not caught by Mom…"

"We'll be careful," Billy said. "Yeah, let's do it now. You're not the only one who's steamed up, Debby. Jeez, did you look foxy when I walked in and saw you. I can't wait to watch you again!"

Together, they slipped out of their clothes: Debby once again out of her short, filmy nightie and Billy from his shirt and shoes and socks and his tight jeans.

Debby gasped when he finally slid the jeans down his legs and stretched out sideways across the bed beside her, so that both of their legs were hanging over the edge and only the flesh of their arms was touching. Billy's hard young prick stood at full attention, pointing directly at the ceiling, and Debby stared at it with wide eyes.

"Goodness," she said in a voice that was half a moan. "It's so big… and strong-looking. Billy, it's… it's lovely… and you're so… so excited!"

"What about you?" he grinned. "Look at those beautiful titties of yours…"

Young and smallish as they were, Debby's tits were indeed works of art, and as they were flattened now because she was lying down, the nipples were especially noticeable. They were coral-colored; erect and terribly excited.

Billy couldn't help himself. He reached over and ran his hand up his sister's warm outside thigh. Her smooth white flesh seemed to quiver with excitement under his touch. The tips of his fingers moved over her hips, up along her warm, flat stomach, up over her ribcage, and at last came to a stop, after the maddeningly slow journey, just beneath one of the thirteen-year-old's jugs. He traced the tips of one of his fingers across a nipple.

"So nice," he sighed. "Debby, you're soooo nice!"

Debby closed her eyes and moaned. "Ohhhhhhhhhhh, Billy… that feels so good…"

Billy just couldn't stop then. He rolled onto his side and brought his lips near her ear. His cock and balls ached, he was so horny. He rested his free hand on her warm, quivering young thigh, and his hand at her boob began feeling her more strongly. He worked his palm in a circular motion over the excited nipple.

"Ohh, Debby," he groaned. "I need you, Sis. We need each other…"

Debby started to moan again, but then came to her senses. With a startled gesture, she brought her hand up and slipped her fingers gently yet firmly around her brother's wrist.

"Billy… wait… no," she said falteringly. "We can't… we can't do that…"

With a sigh, Billy moved his hand from her thigh and pulled his face back from her sweet-smelling hair.

"You're right," he said. "I'm sorry. I'm… I'm just so Goddamn horny!"

Her breathing was coming so fast that Billy could hardly discern her words. Her hips seemed to be rotating with a life of their own and a thin coating of tangy-smelling sweat covered her body. She had spread her legs as far apart as they would go and one of her hands dropped down to the bush surrounding her cunt.

"Billy… Billy," she moaned. "I'm so excited too… I'm… I've got to make myself cum right now. When you played with my titties, ohh, it felt so good… ohhhhh… mmmmmm…"

She had already begun screwing her cunt with her middle fingers. Billy felt a dribble of juice seep from the piss-slit of his prick and drool down the length of his shaft to sparkle in his pubic hair.

"Debby… before you cum… please, lick my palm… lick it with your tongue… give me that much at least…"

"I… I don't understand…"

"Oh, come on, Sis. Hurry! I want to cum with you… if I can't feel you… at least let me know that it's… that it's your spit that's helping me get off…"

"Ohhh, Billy…"

Debby was a "good girl". She'd never heard "dirty talk" before from a boy or a man. But now, seeing her brother's immense hard-on, feeling her own pussy juices gushing from her teenage twat as she diddled herself frantically, and remembering the lovely touch of her brother's fingers on her nipples… the words he spoke, and the horny way he spoke them, were almost more than her senses could stand. Her whole body began to shudder with delightful sexual quiverings, and she was ready to do anything for him to help him feel the thrills she was experiencing.

"Oh, yes… yes, Billy…" she panted.

She was still holding him by the wrist. She brought his hand down toward her hot mouth now and her tongue licked out, covering his palm with her spit. Her spit was thick and hot from her excitement.

"Thanks, baby," he groaned. "Oh, thank you…"

Then he took his hand and began sliding it up and down his horny prick. In an instant the shaft was slick and shiny with his sister's saliva. He felt his asscheeks tighten as he played with himself faster and faster, all the while his eyes drinking in the beauty of his kid sister, lying there beside him, holding and playing with one of her titties while she lay there moaning and writhing and twisting against him, fingering her cunt while her eyes were locked to what he was doing!

The bedsprings creaked beneath them as both of their hands moved faster and faster. Debby had her feet up on the edge of the bed now, her hips bumping and jerking like some topless-bottomless go-go dancer. She was moaning, her climax coming on faster, faster, faster.

Their hips slid and rubbed wetly against each other with the sweat of their passion as they masturbated side by side, watching each other all the while.

"Ohhhhh!" cried Debby at last. "Ohhhh, I'm there… I'm cumming… oh oh oh oh oh…"

Her fingers stopped for just a second. Her whole body seemed to lift off the bed and just hold like that as the unbelievable strength of her orgasm hit her with all the force it had.

"Aaaaaahhhhmmmmmm!" she squealed. "Ohhhhh… I'm cuuummmmiiiiiinnnnngggg… ohhhhhhh… aaaaaaggghhhhhmmmmm!!"

It was like a bomb going off. Billy had never seen anything like it. She writhed and bucked and twisted on the bed like a soul possessed, all the while fingering her cunt and tit, squeezing and pinching them in her pleasure.

It was all Billy needed to send him over the edge as well. With one last increase in speed, he centered the action of his palm just on the head of his roaring dick, and felt the fingers of his free hand grip the bedspread as his legs sprung out straight and stiff from the bed's edge.

"Ohhhhhh… ohhhhh… me toooooo…" he groaned. "Oh Debby… oh, sis… I'm shooting my cum!"

As he gripped his cock with his wet, slippery hand, Billy's load exploded from his dick as if fired from a cannon. It was thicker and hotter than usual, and there was more of it than usual too. As he continued to stroke himself, creamy jets of sperm arced out into the air, landing on the bedspread, on his legs, and on Debby's smooth, tanned legs as well.

The moment of supreme lust seemed to last forever as both children continued to diddle themselves long after the actual moment of orgasm had passed, in an attempt to milk every drop of pleasure from the experience that they could…
