He waited nearly two months to claim the next installment of the
payment due him.

It was night. So late is was well into the early morning
hours. It was just as it had been when Angie had come to visit him for
his second “show” as she had liked to call it.

After forcing her to masturbate in his room for him that day, Angie had
been quiet and sullen for days and had avoided him like the proverbial
plague ever since. Not tonight, though. Tonight it was time for more
payback.

Standing quietly outside her bedroom door, Vic tried the knob. As he’d
expected, the door was locked. Using her previous method, Vic began
tapping lightly on the door, insistent, unceasing, until he saw light
under the door.

“Who’s there?” Angie asked.

Smiling in the dark at the fear in her words, Vic whispered, “Your
loving brother.”

He clearly heard her sharp intake of breath. There were a few moments
of silence, then she asked, “What do you want?”

“What do you think I want?”

“No, Vic  Please ”

“Yes, Angie. You know the game. Do it or you know what’ll happen.”

He heard her quiet sobbing combined with the sound of the door
unlocking. The door opened to reveal her. She was wearing only a flimsy
satin gown.

“Vic,” she said, her tone pleading, “please  Don’t make me do it
again.”

Easing her backwards, Vic stepped into her room and closed the door
softly behind him, locking it. “Yes, Angie. I’m going to make you do it
again. Then a third time. Just like you did to me.”

Tears welled in her eyes. “I’m so sorry, Vic. I never knew what it was
like for you, what I put you through.”

He arched an eyebrow at her. “Honestly?”

She nodded, her expression turning to hope.

“Bullshit,” he whispered.

Her face fell.

He stood watching her. When she made no move and said nothing, he asked
her, “What are you waiting for?”

She opened her mouth, then closed it. Tears streamed down her face as
she pulled off her gown. Beneath, she was wearing only white cotton
panties. She slid them off quickly and stood nude before him.

“Oh,” Vic said, keeping his voice low, “you’ll be wanting to cum a lot
more quietly this time than you did the last time, big sister. If you
make that much noise with Mom and Dad home ” He trailed off, letting
her imagination take over.

Her moist eyes grew wide. “Can you  Will you please let me wait until
sometime when they’re not home? Please?”

He shook his head. “Nope. You got me up in the middle of the night to
masturbate for you. I’m just returning the favor. Be sure to keep the
volume down.”

She nodded, looking miserable, and turned away, sitting on her bed,
watching him. “What if I cum twice for you tonight? That’ll be the
three times. Then we’ll be even. Right?”

He smiled. “Anxious to get it over with?”

“Yes.”

“No. You kept making me wait between performance, making
me deal with never knowing when you’d come back. I want to do the same
to you. I want you to feel everything you made me feel. All of the
humiliation and all of the uncertainty.”

Hot tears streamed down her face.

“You brought this all on yourself, Angie. Every bit of it. Remember
that. You blackmailed me into masturbating for you. I’m just doing to
you what you did to me. You’re actually getting off easy. You know
that? After tonight, you know you’ll only have to do this one more
time. I never had that.”

She nodded, wiping her eyes, then lay back and spread her legs wide for
him to see, showing him everything, as she began to diddle her already
half-erect clit.

Vic pulled her desk chair over and sat, watching her. He noticed that
she hadn’t put up much of a fuss this time and was far, far quicker to
start. And she had already been showing blatant signs of arousal before
she started

Angie’s twat began to drool quickly and she dipped two fingers into her
liquid musk and scrubbed them over her clit. She was already whimpering
softly.

“Remember,” he told her. “You have to cum quietly.”

She nodded, splaying her slender legs farther apart for him. Vic
noticed that her summer tan was fading away. He found himself looking
forward to next year’s tan. Shaking his head, he forced the thoughts
away and leaned forward, staring at Angie’s wet slit.

“Spread your pussy open wide for me, Angie. Let me see deep inside of
you as you masturbate.”

Without a word or any hesitation, she slid her other hand from her hard
nipples to her twat, using the fingers of one hand to peel the petals
of her sex wide open, revealing glorious pink inner flesh, as she
scrubbed harder at her clit with her other hand.

“You’re really wet,” Vic whispered to her.

“I always get very wet,” she answered.

The clarity of her response startled him. He looked up at her face and
was surprised to see her head tilted to see could see him from her
prone position. She was smiling at him, though her eyes were still damp
with tears.

“What’s wrong?” he asked her.

“Nothing,” she said. “But I’ve got nothing else to do while I
masturbate – nothing else to look at. And you’ve said the last two
times you came for me you were looking at me. I figured you’d want me
to do the same. Cum looking at you, I mean. You know, as part of the
payback you’re extracting.”

Vic leaned back in his chair. That hadn’t even crossed his mind and her
words gave him pause. “Yeah,” he said. “I’m glad you’re making this so
easy on yourself.”

“It’s not so bad,” she said. “We’re brother and sister. We used to take
baths together when we were little. Remember?”

He nodded, his gaze flicking from her face to her wide-spread, oozing
snatch, and back.

“Neither of us as anything the other hasn’t seen before. Even barring
recent events,” she whispered. “Once I get past the oddity of having my
little brother watch me masturbate, it’s not so bad.”

Vic smiled, confusion whirling in his mind. “That’s good. I’m glad of
that.”

“Did you feel the same?”

“Huh?

“When I was making you masturbate for me. Did you feel the same? That
it was weird, but not really bad to cum with me watching you?”

Vic laughed, genuinely amused. “I never really got past the strangeness
of it, honestly. Which is, I guess, why I’m doing this to you now. If
I’d thought it wasn’t that bad, I probably wouldn’t have even gone to
the expense of buying that hidden camera.”

She answered with a noncommittal grunt and shoved a pair of dexterous
fingers deep into her sopping twat with a wet squelch. “This isn’t so
bad,” she said. “Not bad at all.”

Vic stared at her. Was his sister actually liking that she was
masturbating openly with him watching? No, he decided. She was playing
him. She wanted him to think she liked it in the hopes that, deprived
of the full measure of his revenge against her, he’s forget about
making her do it the third time.

“It won’t work,” he told her.

Still holding her pussy open for him while she busily rubbed her hard
clit, she frowned, asking, “What won’t?”

“Your little act.”

“What act, Vic? What are you talking about?”

“Don’t bullshit me, Angie. I know what you’re doing. It won’t work.
After tonight, I’m still going to make you masturbate for me a third
time.”

“I know,” she said.

“Then drop the act.”

She frowned, looking genuinely perplexed at his words. “Okay,” she said
after a few moments.

“Just hurry up and cum,” he said. “I want to go back to bed.”

She smiled at him again, still watching him with her head tilted by her
shoulder. “You can’t rush some things, Vic. I’ll cum when I’m ready.”

He nodded and shifted his gaze to her open twat once more. Clear, musky
liquid ran from her in a steady stream, its heady scent assailing him.
Her pink flesh pulsed with her passion and lust.

“How do I look?” Angie asked.

Vic glared at her, twisting his head quickly, surprised to see that she
was still watching him.

“Do I look good?”

“Stop it.”

“Stop what?”

“What you’re doing!”

“Masturbating?”

“No! The act! Quit pretending that you like having me
watch you!”

“It’s not so bad,” she said again.

“It should be!”

“Why?”

“Because it isn’t natural for brothers and sisters to watch each other
masturbate!”

“Keep your voice down, Vic. And how do you know it isn’t?”

His mouth worked for several moments before he actually said anything.
“It can’t be normal! It’s wrong!”

“Is it?”

“Yes!”

“Says who?”

He paused again, then said, “No one.”

“Then how do you know it’s wrong?”

“It just is!”

“Why?”

“It isn’t natural!”

“Maybe it is. You’re my only brother and I’m your only sister. Maybe
this is normal and natural.”

“It can’t be!”

“But maybe it is.”

“Just hurry up and cum, will you?”

“I told you already. Some things can’t be rushed. I’ll cum when I’m
ready.”

She fell silent again. He watched her watch him watch her for a few
more moments, then shifted his gaze back to her twat. She was still
holding herself wide open for him, still rubbing her clit with the
fingers of her other hand.

“It feels good,” she said.

“Good,” he answered quickly.

“It feels very good.”

“Good.”

“I feel like I’m about to cum.”

“Good! Just keep your voice down. You made a lot of noise last time.”

“I know. I’ve never made that much before.”

He looked up at her again, startled by her words. “What?”

She chuckled. “Please, Vic. You know when I first had sex.
And, in case you’re wondering, Daniel and I have only
fucked twice since then. I’m twenty-years-old and I’ve been with a guy
a grand total of three times in my life.
But I’ve had hundreds of orgasms by doing just what I’m doing now.
Trust me, little brother, I’m just as horny as you are. I masturbate as
much as you do. Maybe even more.”

Despite himself, he grinned back. “That’s doubtful.”

“You think so?”

“Yeah. I do.”

She rubbed her clit furiously as she asked, “How many times on an
average week do you masturbate, Vic?” Her breath was growing ragged.

Glancing at her streaming pussy, he said, “I probably do it five or six
times a week.” He was surprised at how easy it was to tell her such a
thing. But then, she already knew he masturbated regularly. And he was
sitting there in his pajamas while she was completely naked and openly
masturbating for him.

Whimpering in pleasure, she closed her eyes and diddled her stiff clit
even faster, breathing harder. “I make myself cum at least once a day.
Every single fucking day.” Each word was emphasized by a grunt of
passion. “Some days I cum two or three times a day, Vic. Did you know
that?”

“No,” he answered honestly. “I didn’t.”

She forced her eyes opened and stared at him. He could see her lust
burning in her gaze as she worked her clit, bringing herself ever
closer to climax.

“You never knew,” she said, “that your big sister, who’s room is just
across the hall from your own, masturbated her pretty pink pussy to
orgasm every fucking night? Or that I often start my day off by playing
with myself until I cum, writhing here on my bed, naked, my skin
flushed with passion and desire? You honestly never knew that?”

“No,” Vic said, watching her smoldering eyes, smelling the fragrance of
her liquid satin as it poured from her pulsing, pink twat in waves.

Her bare chest, rosy with excitement, heaved. “I’m surprised, Vic. I
always thought you knew how often I masturbated. There are times I’ve
not been nearly as quiet as I should’ve been. It’s nothing short of a
miracle that you’ve never heard me and walked in on me like I did on
you that night. Yes, there’ve been times, plenty of them, I’ve been so
fucking horny and needed to cum so fucking badly that I’ve forgotten to
lock my door.”

“Wow,” Vic whispered.

She nodded, her lust-filled gaze still fixed solidly on his own, her
mouth tight as her entire body tensed, preparing to climax. “Yes, Vic,”
she whispered. “I’ve often been surprised you’ve never walked in on me
when I’m-” Her words gave way to ragging gasps and her naked body
shuddered. “Oh!” she whispered. “Oh, yes! Fuck, yes!” Each word was a
bit louder than the one before it.

Vic leapt from the chair and onto the bed with Angie, quickly covering
her mouth with his hand, stifling the vocal evidence of her orgasm as
it swept through her. Though her body wriggled and bucked, he kept his
hand in place, hyper-aware of her soft lips and hot breath on his palm.

Once she calmed, he slowly removed his hand and backed away from her.
Angie lay there, panting and flushed, watching him, a faint smile on
her face. “Two down, little brother. One time to go.” As she spoke, she
slid a finger easily in and out of her still-swollen, dripping cooze.

Without a word, Vic quickly unlocked her door and fled to his own room.

“I can’t believe it!” he whispered to himself. “She liked that! She
actually liked striping naked and masturbating for her own brother!
She’s sick!” He turned, then, facing the door, making sure he’d locked
it when he came in. “No,” he whispered aloud. “She didn’t! She couldn’t
have! The whole damn, fucking thing was an act! It had to have been!”

As he spoke, he pulled off his pajamas, rendering himself naked. His
lean cock bounced at full attention in the air before him. He stroked
it, hoping that Angie hadn’t noticed the telltale bulge of his erection
as he’d watched her.

“Fuck!” he said aloud, his voice more than a whisper. He’s just
realized that the hand he had wrapped around his cock had been across
Angie’s mouth only moments before. He’d touched his sister’s tender
lips, felt her warm, moist breath upon his palm, and now had that same
hand wrapped around his stiff cock. And he was already dripping pre-cum
in his excitement.

Despite the realization, Vic was unable to bring himself to release his
shaft. He began to stroke, his mind instantly calling up images of
Angie, lying nude on her bed, her snatch soaked from the orgasm she’s
just had while his hand – the very hand that now was coaxing Vic
himself to an orgasm – was across her mouth

“Fuck!” he whispered, as his load of jizz burst up quickly, surging
through his cock and flying free. It landed on the floor three feet
away just as he got his free hand up in time to catch the rest of his
load as it spurted out, hot and fragrant and sticky.
