Chapter 1
"I think Johnny's a dream!" Sue said.
"So do I," said Barb. "But I like Carl. I think he's just so sexy!"
Billy was listening to the girls through Sue's bedroom door. She was his older sister, and Billy felt left out. He liked to talk to his sister and her girlfriends. But they were always going into Sue's room to talk about boys.
"He is sexy," Sue said in agreement with Barb. "And he's got a big prick. You can see it bulging in his pants."
"I know," Barb giggled. "I think he caught me staring at it the other day. I thought I was going to die of embarrassment!"
By that time, Billy's prick was hard. Just listening to his sister and Barb talking like that was enough to turn him on. But then, being a virgin, Billy could be turned on by a hard-boiled egg.
"Karen said she could feel his prick pressing into her belly when he kissed her," Sue said. "She said it felt like a log in his pants."
Billy's ears burned as he listened to the girls' private conversation. He had often wondered what girls talked about, and if they had the same things in their minds as boys did. Apparently, they did.
"Did you ever see a hard cock?" Barb asked Sue.
"Once," Sue said, "I saw my brother's."
Billy's eyes bulged and his heart skipped a beat. When could his sister have seen his hard-on?
"Billy left his door slightly opened once when he was jerking off," Sue continued. "I peeked in and there he was, sitting on his bed looking at one of the dirty magazines he keeps under his mattress."
Billy felt weak. Not only had his sister seen him jerking off his prick, but she knew about the skin magazines he kept hidden. The poor kid didn't think he could ever face his sister again. But he pressed his ear closer to the door to hear what else Sue would say about him.
"Wow!" Barb said. "I'd love to see a boy jerking off. How did he do it?"
"He had his hand wrapped around his prick," Sue explained. "It was huge. I could see the head of the thing bulging as Billy's hand pumped up and down. And his balls were bouncing on his thighs."
Billy felt about two inches tall. His hidden life was exposed. Now everyone would know of his shame.
"Didn't it get you hot?" Barb asked. "I know my cunt would be drooling if I saw something like that!"
"It sure did get me hot!" Sue said. "In fact, I couldn't help sticking my finger up my pussy!"
Billy's heart skipped another beat. He could hardly believe that he was hearing his sister admitting to the same vice he was guilty of.
"Right there in the hallway," Sue continued, "I rubbed my clit until I came. And I came at the same time as Billy. I could see the cream spurting from the head of his prick."
Suddenly Billy felt better. So what if he had been seen jerking off! At least he wasn't the only one doing it. He realized that he would give anything to see his sister rubbing her cunt. Maybe he should spend more time hanging around outside her door.
"God!" Barb gasped. "Just hearing about it is making my pussy wet!"
Billy tried to imagine Barb's wet cunt. But his knowledge of cunts was very limited. He only had a rough idea of that territory.
"Yeah, my cunt's wet just from remembering it," Sue said.
"Hey, Sue," Barb said slowly, "would you like to do it now-rub yourself off, I mean? We could do it together."
There was a pause. Billy, now frozen with desperate lust, hoped his sister would consent to Barb's kinky idea. Then Billy's brain began buzzing with the effort to figure out how he could get to watch the girls' mutual masturbation.
"Yeah, that would be fun!" Sue finally said. "I've never seen how another girl does it. I wonder if we do it the same way?"
They're going to do it! Billy exclaimed silently in his burning mind.
He sank to his knees and put his eye to the keyhole. He could see right into his sister's room, he found. But all he could see was her dresser. The girls weren't in sight.
Billy realized that they would be on Sue's bed. The bed couldn't be seen from the keyhole. He would have to look through her window.
"Come on," Barb said. "Let's get undressed."
Billy had to act fast. He couldn't bear to miss a second of the fantastically sexy sight that awaited him.
The bedrooms were on the second floor. But that would be in his favor, Billy thought as he ran down the stairs. If Sue's room were on the first floor, she would pull down her shade for sure. But since no one could see into her room, she would probably leave the shade up. Of course, she never would guess that her horny brother would climb up a ladder to peek at her.
In less than a minute, Bill was hoisting a ladder against the side of the house under his sister's window. It was a good thing that his mother wasn't home. As for the neighbors, he could pretend he was fixing the sill of his sister's window, or something.
As Billy began climbing to the vantage point that would expose the girls' jerking off to his eager eyes, his legs felt like jelly. But his horny rage made him fly up the ladder.
The shade was still up, Billy noticed. His heart was pounding so hard, he was afraid the girls might hear it. His mouth was dry, his throat constricted. His hard, throbbing prick was bent painfully in his pants.
But nothing could stop that desperate boy.
When the top of his head reached the window sill, he slowed his climbing. His head rose above the sill like the sun rising above the horizon.
Even though Billy expected it, he couldn't believe the scene that met his gaze.
The girls were standing at either side of the bed, pulling their clothes off. His sister already had her blouse off. She was leaning over as she stepped out of her jeans. Her big tits hung from her chest and swung with her movements. Then, when she had pulled her feet from her crumpled jeans, she stood up. Her tits stood proudly on her chest with a shimmer.
Billy swung his gaze to Barb. She was hopping on one foot while tugging a sock off the other. Her blouse was still on, but it was open. Her small firm tits jostled with her hopping.
When Barb had her socks off, she peeled the blouse from her shoulders. Her tits were like gentle hills, topped with a pink cap of puckered flesh.
By that time Sue was pulling down her underpants, and she had Billy's attention.
The boy stared at his sister's cunt with greedy fascination. He fixed the image of that fuzzy triangle in his mind. Then his eyes went to her tits again. They were big and beautiful-creamy mounds of shimmering flesh with bright pink nipples as big as silver dollars.
Billy watched his sister throw herself down upon the bed with a bounce-and her tits bounced with their own rhythm.
Now Barb was pulling down her underpants. Her cunt seemed smaller-a tight arrowhead of bristling hair. Then Barb sat down on the bed.
It occurred to Billy through his wild passion that the girls might notice him peering in at them. And it scared him, but only because they would bring down the curtain on the show. He knew his own embarrassment would be a small price to pay for this performance.
Billy could see that the girls seemed shy. Now that they were naked and on the bed together, they didn't seem to know what to do next.
Jerk off! Billy said to himself over and over, as though he could cheer the girls on by mental telepathy. And it seemed to work.
Barb turned toward Sue so that Sue could look into her crotch. Sue swiveled herself so that her crotch was facing Barb. Then both of them reached for their own cunts.
From his position at the window, Billy could see both girls' tits, his sister's ass, but neither of their pussies. Nevertheless, it was a spectacular sight.
This was the most exciting moment of Billy's life!
"Do you stick a finger up your cunt or just rub your clit?" Barb asked Sue.
Billy could hear the conversation, and it added to his already explosive lust.
"Sometimes I stick a finger of one hand up my pussy while I rub my clit with a finger of the other hand," Sue said as she brought her other hand to her crotch. "Like this."
Sue was lying on her side, one leg raised into the air. Billy saw her reach under her raised thigh and insert her finger out of sight into her cunt.
Barb was sitting upright. Her legs were spread and her knees bent. But she only had one hand at her crotch. Her other hand was behind her, supporting her in her sitting position.
"Sometimes I tickle my twat till I'm almost coming," Barb said. "Then I stick my finger up my pussy and wiggle it all around. Then I put it back on my clit. That way I can make my orgasm last a long time."
Billy wished he could have the view that the girls had of each other's twats. Looking into a spread gash was one of his dreams. But he was so horny as it was, a view like that would have made him shoot his load right in his pants.
Even in his passion, Billy's brain was still working. He wondered what would happen if he crawled through the window and begged the girls to let him join them. After all, they would love to see him jerk off-they'd already said so.
But Billy decided not to chance it.
Then he thought about pulling out his cock right there on the ladder. If he could jerk off while watching, it would be much more fun. Besides, his prick was almost bursting already.
But he knew he could never do that. He was in full view of any of any neighbors who happened to look his way. He wasn't so far gone that he could jerk off with an audience.
So Billy had to settle for being a spectator. But that wasn't so bad. In fact, it was fabulous!
He watched the girls' arms moving with the motions of their clit-rubbing. His sister's left tit could be seen protruding beyond her arm, and it was swaying with her movements. Barb's smaller tits, seen in profile, were moving slightly, despite their small size.
"I love to do this," Sue said. "And watching you is almost as exciting as watching my brother."
Now, rather than being embarrassing, it was exciting to hear about his sister's watching him jerking off, Billy realized.
"I love this, too," Barb said. "I do it all the time."
Billy leaned forward. His prick was pressed against one of the rungs of the ladder. In that position, the twitching of his cock make his whole body jerk.
But he wasn't the only one jerking.
He noticed that his sister's whole body was moving with the rubbing motion of her arm. Billy knew she was getting as excited as he got just before coming.
Barb's body was swaying, too. Her eyelids were drooping as her arm began moving faster and faster.
"Ohhhhh, God! I love it!" Barb gasped.
"Yeahhhhh. It's so wonderful!" Sue sighed.
The sight of the two chicks in heat burned into Billy's brain. He knew he would never forget this rare experience.
Suddenly, Billy saw his sister throw her head back. Her body tensed. Her arm was a blur of motion.
"Ahhhhh . . . ohhhhh!" Sue wailed. "God, I'm coming!"
Billy had never realized that a girl could come like that. But it was obvious that his sister was in pure ecstasy.
Sue fell onto her back. Both hands were still at work at her crotch as she kicked her legs in the air. Her tits rolled around on her chest.
Then Barb's head fell forward as she seemed to curl up into a ball of lust. Her arm was a blur, too.
The girls made the bed bounce with their lustful writhing. Their voices joined in howls of bliss. Billy watched and listened as his prick throbbed and his face burned.
Finally the girls lay still. Billy could see their crotches now. But their legs were no longer spread, so from the window he couldn't see much. Still, it was a continuing delight to watch those chicks lying there in their nakedness.
Billy scurried down the ladder, grabbed the ladder and carried it to the garage.
As much as he would have liked to keep the naked girls in view, there was something else he had to take care of.
As soon as he dropped the ladder he unzipped his fly and pulled out his prick. Then, with the memory of what he saw through the window burning in his mind, he jerked off.
After the show he'd seen, it took only a half dozen strokes to bring his jism to a spurting fountain in front of him.
When Billy went back to his room, his sister's door was still closed. It was quiet in her room. Billy could picture the scene. He thought of knocking, just to see what would happen. But he couldn't face his sister and Barb at that moment.
Billy was completely devastated by the experience he'd just had.
