Chapter 3
Billy knew that Barb had told his sister what had happened. After all, girls who jerked off together would share their secrets. So his sister knew that Billy had peeked into her window. Billy thought she had been treating him rather coolly since his near-miss with Barb.
Billy and Sue had always been on good terms-as close as a brother and sister could be. So he was eager to explain his voyeurism. If only she could understand how horny he was, she couldn't blame him, Billy thought.
A few days after the fiasco with Barb, Billy knocked on his sister's bedroom door before she went to sleep.
"Come in," Sue called in a formal tone.
When Billy opened the door he found her in bed, her blankets pulled up to her waist, her tits held in the low-cut top of her nightgown.
The atmosphere in Sue's room excited Billy. There was a warm sensation in the air, as though the girl's body gave off a mist of femininity. And the sweet smell of her perfumes and soaps excited the boy.
"Have you seen Barb lately?" Billy asked his sister for lack of a better way to start the conversation.
"Of course," Sue said shortly. "I see her every day at school."
"Is she going to come over again? Overnight, I mean?"
"Why do you want to know?" Sue asked. "So you can peek at us again?"
Billy winced. But he was glad his sister had broached the subject. He wouldn't have been able to.
"She told you, huh?" Billy said.
"Of course she did," Sue said.
Billy was feeling awfully embarrassed. But talking to his sister about him peeking at her and Barb jerking off excited him. His prick began to swell in spite of his embarrassment. Sitting down at the foot of his sister's bed, he hid the growing bulge in his pants.
"I tried to explain it to her," Billy said. "I was just passing your door, and I heard what was going on. Gee, Sue, I was so horny I couldn't help myself. So I put the ladder up outside your window. I couldn't see much, anyhow. Besides, I heard you telling Barb that you peeked at me jerking off once."
Now Billy was very horny. Talking about peeking and jerking off was almost as much fun as doing it.
"When I peeked at you it was only because you left your door open," Sue said. "It was almost as though you wanted me to peek."
It had never occured to Billy before, but maybe he did want his sister to see him jerking off. Certainly the thought of her watching his most secret ritual excited him.
"But I didn't go put a ladder under your window," Sue continued.
"Come on, Sue," Billy said. "Don't be mad. So I watched you and Barb jerking off together-big deal!"
"It is a big deal!" Sue said stubbornly.
Billy didn't want to leave it at that. Not only was he hoping for another chance at Barb's pussy, he hated the thought of leaving his sister's room. He was having a good time talking about these things with her.
"I don't want you to be mad at me," Billy said. "Can't we just forget about it?"
"No!" Sue said sternly. "How can I just forget it? But maybe you can do something to make us even."
Billy felt his prick give a powerful jolt in his pants. Somehow he began to suspect he was in for something exciting.
"W-what do you mean?" Billy asked.
"Let me watch you jerk off," Sue said eagerly. "Then we'll be even."
Billy knew that it would be very exciting to have his sister watch him jerk his cock. But could he do it in front of her? She hadn't even seen him naked since they were both little kids.
Then Billy remembered that his sister had peeked at him already as he had jerked off. She knew what his stiff prick looked like and how he pumped it with his fist. Yes, he would love to jerk off for her! But he couldn't make his voice work. He just stared dumbly at her.
"Come on," Sue said. "Jerk off for me. It's only fair after you peeked at me and Barb doing it."
"Okay," Billy finally managed to croak.
But as his sister sat under her covers, the boy remained frozen at the foot of her bed. How does a guy go about jerking off in front of his own sister?
"Well?" Sue asked.
"Huh? You mean right here? Now?"
"Sure, come on," Sue urged.
Billy had never been so excited-not even when he'd had Barb naked in his arms a few nights before. He could hear his own heart pounding and his prick was about to tear his pants apart.
"I'll do it if I can watch you doing it, too," he offered.
"No," Sue insisted. "I just want to watch you."
Billy wouldn't refuse. He couldn't. Besides, it might be even more exciting with his sister hidden under her covers.
Shivering with passion, Billy saw his sister's eyes drop to the front of his pants, where his cock was forming a huge lump. He began to unbuckle his belt.
His fingers shook so badly it took Billy quite a while to get his pants unfastened and pulled down. But when he did, he saw his sister's eyes grow big with awe as she watched his hard prick holding the elastic of his underpants away from his belly.
Billy took a deep breath and pulled down his underpants. When his prick hit the cool air of the room, Billy could almost feel his sister's gaze envelop his cock.
"God!" Sue gasped as she stared at her brother's enormous cock standing up at an angle from his crotch.
A feeling of pride mingled with Billy's lust. He knew he had a prize winning pecker.
Now came the more difficult part. With his sister staring at him an arm's length away, Billy had to grab his prick and pump it until the jism flew.
He sat down at the foot of the bed again and turned toward the girl sitting up at the other end. Her eyes hadn't moved from his jerking cock since he had unsheathed it.
"Go ahead, Billy," Sue said in a breathless voice. "Jerk off!"
On command, Billy reached for his prick. He took the thick shaft in his hand and wrapped his fingers around it.
With his pants and underpants around his ankles, his thighs slightly spread, his body turned toward the girl under the covers, Billy slid the loose skin of his hard cock up and down.
With each up and down motion of his fist, Billy became more and more excited. And knowing how his performance affected his sister made his lust multiply.
Sue raised her hands to her face, touching her fingertips to her cheeks. Her mouth opened slightly as she stared.
Billy felt his balls lifting slightly from his thighs with each upstroke of his hand. He felt the head of his cock grow taut with each down stroke. He wasn't usually so aware of the motion of his prick and balls when he jerked off, but now he was imagining the impact of the sight on his sister.
"God, I never ..." Sue said in a hoarse whisper. "Never saw anything like ..."
"Ahhhhh," Billy moaned as ecstasy began to radiate through him from his burning prick.
He was going to come soon. Watching his sister's face, he eagerly waited to see the reaction of his imminent explosion.
"Ahhhhh," Billy moaned again, louder this time.
He arched his back. His legs shook. He knew that he was exaggerating his lust, but putting on a show for his sister was turning out to be even more exciting than he thought it would be.
The more Billy moaned and shook, the wider Sue's eyes became. Billy's fist was pumping up and down with tremendous speed and power. His balls hopped and bounced between his thighs.
The startled expression on Sue's face when great gobs of cum flew into the air from Billy's prick was wonderful to see. Billy had never seen his sister looking so enraptured-not even when she had gotten her dollhouse as a little girl.
Billy tilted his still-spewing prick toward his sister. But by that time, most of the thrust had been spent, and his jism merely popped, rather than shot. Still, he managed to send a drop onto her covered foot, a short distance from his knee.
"Wow, I never knew it could shoot like that!" Sue gasped.
His sister had been impressed, Billy could see. And he began to wonder if she had been turned on by the sight. He guessed that she had.
"Hand me a tissue, will you?" Billy said when he stopped pumping his prick.
"I'll mop it up for you," Sue offered.
Grabbing a tissue from the box on her end table, she crawled from under her covers toward her brother.
Billy hadn't expected this. His prick, which had begun to deflate, stiffened again.
Sitting still, breathing hard, Billy watched his sister kneel over him. Her tits hung heavily and the neckline of her nightgown sagged. The snowy white mounds of her tits hung a few feet in front of Billy's face. Although the nipples were still hidden in the gown, Billy could imagine how her tits would look if they were totally exposed. And he knew how wonderful it would be to scoop up one in his hand.
But he couldn't concentrate on her tits any longer.
Sue had begun to mop up the cum that was scattered all over his belly and thighs. Beginning with his thighs, she carefully wiped up the thick fluid.
"Gee, it's weird stuff," Sue said as she got some of his cum on her finger.
She stopped cleaning him off as she rubbed a pearly droplet between her fingers and thumb. It was a strange sight for the boy-watching his sister marvel over the consistency of his cum.
Then she began to finish the job of mopping up.
"Isn't your cock supposed to get soft again after coming?" Sue asked.
"Yeah, usually it does," Billy said. "But with you doing that . . . well ..."
Sue had begun to wipe the base of his prick and his balls with a tissue.
"You mean I'm exciting you?" Sue asked with exaggerated innocence.
Billy didn't answer her question-it hardly needed an answer. But he asked one of his own.
"Will you jerk off so I can watch?"
Billy saw a twinkle in his sister's eyes. She continued dabbing at his balls and into his pubic hair with the tissue.
Although she hadn't answered his question, Billy had the feeling that she was going to do it for him. He got so excited, his prick stood fully erect and began jerking again.
"You look like you could start all over again," Sue said.
"I will start all over again if you'll do it, too," he urged.
Still Sue didn't answer, but Billy was geting more and more sure that she would. By now he would give anything to look into her cunt as she rubbed herself with ecstasy.
"Come on, Sue," Billy said. "It'll be fun! Come on."
He couldn't help begging. He would do anything to get her to agree.
Billy suddenly covered his hard cock and hanging balls with his hands. He wasn't going to let his sister enjoy his nakedness any longer unless he got his way.
"You already saw me jerk off when you peeked in my window," Sue said.
Billy recognized his sister's tone of voice. She was going to torture him as much as possible. But he was helpless-he had to play her game.
"Yeah, and you saw me jerk off before, too, when you looked into my room," Billy argued desperately. "So you saw me jerk off twice now, and I've only seen you do it once."
Sue pretended to consider this for a few seconds.
"Oh, all right," she finally said as though she were agreeing to wash some dishes.
But Billy knew that she was excited and eager to jerk off. It seemed that the temperature and humidity had soared in the room, and Billy imagined that his sister's pussy drooling had caused the change.
As Sue sat slowly back against the headboard of the bed, Billy took his obscuring hands away from his prick. He watched hungrily as his sister began pulling up her nightgown.
Sue's long, shapely legs began to appear. With every inch of flesh she exposed, Billy's heart beat faster.
Sue lifted her gown with dramatic slowness. The soft material slid over her knees and up her thighs. It seemed that the closer the hem of the gown came to her crotch, the slower it was. Billy thought that might just be his imagination as he grew wilder with passion.
Staring into the darkness between his sister's thighs, Billy panted in heat.
Finally, the girl lifted her ass from the bed and slipped the nightgown up around her waist. Billy found himself staring right into her hairy cunt.
Billy could see the long slot of Sue's pussy. He saw how the opening led between her thighs to her twin ass cheeks, which showed below her twat.
"Spread your legs," Billy whispered.
Sue did so, and Billy saw her pussy open slightly. A shiny wet ridge of pink flesh showed. Then Sue spread her legs much wider.
Now the full glory of an open cunt showed between the girl's silken thighs.
Billy had never imagined such a sight. And to think that although he had lived his whole life among women and girls, he had never before seen the beauty of a spread cunt.
The chubby outer lips of Sue's cunt were pulled aside. Between them Billy saw delicate ridges of flesh. They formed a puckered point near the top of her slot, then ran down either side of the deep, dark cavern of her pussy.
The interior of that gaping snatch looked like silk as it shone. But Billy knew that the shine was caused by the fragrant juice he could smell now.
Below the spread cunt, Billy could see the tiny aperture of his sister's asshole.
As he stared into the dark void of her cuntal pit, Billy couldn't help imagining how it would feel to plunge his twitching cock in there. But this was his sister, so he couldn't possibly fuck her. Even jerking off together was sort of perverted, Billy suspected.
In his cunt-struck rapture, Billy had begun pumping his prick again.
"I've never seen you looking so serious," Sue said. "You look like you're in a trance."
But Billy didn't answer, for he was in a trance-a trance of lust.
"Show me how you jerk off!" he said without taking his eyes from his sister's pussy.
Sue slowly reached for her cunt. She covered the hairy upper part of her mound with her hand, letting her fingers fall over the open slot. Then she placed her middle finger on the spot where the inner lips of her pussy came together above the dark entrance to her body.
Sue began moving her fingertip as she pressed that tender spot. From side to side, up and down, and in a circular motion her finger moved.
"Is that all you do?" Billy asked.
It seemed surprising to the boy that a girl could get so worked up by merely wiggling her fingertip. After all, he had to pump his hand fairly violently in order to come.
"Well, sometimes I stick a finger up my cunt," Sue said.
"Let's see how!" Billy panted.
Sue brought her other hand into action. She reached under one lifted thigh to the lower portion of her spread pussy. Then she inserted her other middle finger into the deep hole Billy had been so fascinated with.
Billy watched his sister rubbing her clit and stirring her cunt. The sight made his head reel.
Having just shot a load a few minutes before, Billy could really flail at his cock now. But it wasn't long before he felt the first stirrings of an orgasm. With his sister's masturbation to watch, it was going to be a good climax-better than the first.
Sue was squirming by that time, too, just as she had been when Billy had peeked into her window. She began to go wild with passion. And now Billy had a ringside seat.
It was hard to tell which of them was making the bed bounce more.
Sue's ass was rising from the bed as she grew rigid with lust. And as she lifted her hips, Billy got a better view into her pussy. The sexy odor of her flowing juice increased, too.
"Eeeeee," Sue squealed.
Billy gasped. This was almost too much for him-he couldn't believe his own eyes.
Sue was suspended like a bridge. Only her feet and shoulders and head were on the bed. The rest of her shook and quaked. Billy could see her ass quivering below her out-thrust crotch.
Billy was pumping his cock for all he was worth. Coming twice like this was wonderful, but it took some work.
"Ooooo," Sue moaned again in a shrill voice.
"Ah, ah, ah!" Billy gasped.
Together they sounded like an old steam locomotive blowing its whistle.
Finally, just as Billy managed to squeeze a few drops of jism from his cock, Sue collapsed on the bed. They both slowed their masturbatory exercises slowly.
"Th-that was great," Billy said. "I love watching you do that!"
"Yeah ... I love watching you, too," Sue said.
Even after two orgasms, Billy was disappointed when Sue pulled down her nightgown. He could have gone on staring at her cunt all night.
"Do you do that very often?" Sue asked her brother.
He admitted that he did. He told her how he had jerked off in the art gallery once. Sue admitted doing it in school a few times.
They talked about jerking off until they couldn't keep their eyes open any longer. Finally, Billy left his sister and climbed into his own bed. He knew he would never be the same again.
