April sat perfectly still. Her back was straight. Her thighs were pressed together. Her chest was out. Her chin was up. And her hands were clasped on her lap.   She was wearing a button-up sweater and jeans.

A minute ago she had been relaxing on the office chair, laughing at something her sister had said. That was before Julie had started tapping her nails on the desk. One. Two. Three. Pause. One. Two. Three. Pause. Repeating over and over until April forgot what she was laughing about. Forgot where she was. Forgot everything but the tapping and her sister’s voice.

It wasn’t the first time this had happened, but she didn’t know that.  All she knew was that she needed to listen. To be still. To be a good girl.

She was a good girl and her name was April, and Julie was her sister and whenever Julie was tapping her nails and talking, telling her to relax, she stopped everything and paid attention. And when Julie told her to empty her mind, she emptied her mind. Whatever Julie told her to do, she did, because that is what good girls do.

Julia watched her, tapping softly, never changing the intensity or the tempo until she was convinced April was under.  Only then did she stop.

“Do you remember what we did last time, April?”

“Last time?” she asked, furrowing her brow as she tried to remember. “I…”

Last time she’d taken off her top in front of Julie. Exposed herself. Because Julie had told her to. Last time she’d unzipped her pants and slipped her hand into her panties and masturbated while Julie watched. She remembered now.  She smiled at the memory. It has felt so sexy, being watched as she teased herself, brushing her clit, running her finger up and down her wet slit, getting her juices all over her fingers.

“Do you remember who I am, April?”

“You’re my sister,” she said after a short pause, smiling shyly, her gaze settling on Julie’s face.

“And do you remember what I told you last time?”

April frowned, searching her memories, a confused look on her face. “I… I’m not sure.”

Julie moved closer, sitting on the edge of the desk, close enough to reach out, if she wanted to, and touch her younger sister.

“While you were touching yourself for me. While you were playing with your wet pussy while I watched.  Do you remember now?”

“You told me that good girls don’t come without permission. I remember it now.”

“And are you a good girl, April?”

“I want to be.”

“When I tell you to wake up, you won’t remember any of this. Understood?”

“Yes, Julie.”

“Wake up.”

April sat perfectly still. Her back was straight. Her thighs were pressed together. Her chest was out. Her chin was up. And her hands were clasped on her lap. She was wearing a tank top and a pair of shorts while listening to Julie’s nails tapping hypnotically on the lacquered surface of the desk. One. Two. Three. Pause. One. Two. Three. Pause.

And then, she stopped.

“Go sit on the couch, April.”

She didn’t hesitate. She simply stood and moved to the couch and sat herself down, posed exactly as she had been on the chair. Back straight. Legs together. Chest out. Chin up. Hands folded on her lap.

“When was the last time you had an orgasm, April?”

April’s brows knitted together, and she clenched her fingers together before relaxing again, her voice meek as she answered.

“Four weeks.”

“And why is that?”

“Because Good girls don’t come without permission. And I want to be a good girl.”

“Take off your shorts.”

Julie watched as her sisters dutifully removed her shorts, carefully placing them on the cushion beside her, her smile shy when she raised her face to stare at her sister.

“Masturbate for me, baby.”

April didn’t hesitate. She began to circle her clit with her thumb, whimpering softly as she traced her glistening lips with her fingers. It didn’t take long for her pussy to start leaking on the cushion of the couch, turning the sage green material dark.

“Feels good, doesn’t it, April.”

“Stop.”

April stopped immediately, trembling with the effort of pulling her hands away from her pussy, panting hard. Watched as her fingers curled and then settled on her bare thighs. Her nipples were denting her top, and there was a tiny bit of drool at the corner of her mouth.

“Put your shorts back on, April. When you wake up, you won’t remember any of this. Understood?”

“Yes, Julie.

April sat perfectly still. Her back was straight. Her thighs were pressed together. Her chest was out. Her chin was up. And her hands were clasped on her lap. She was wearing a pale yellow sundress and plain white cotton panties while listening to Julie’s nails tapping hypnotically on the hard surface of the desk. One. Two. Three. Pause. One. Two. Three. Pause.

“When was the last time you had an orgasm, little sister?”

“Nine weeks ago,” April said, her words dripping with frustration.

“And remember what you asked last time?” Julie said softly as she perched on the edge of the desk, her skirt hiked up so that April could see a glimpse of her lacy pink panties, the top three buttons of her blouse undone so that April could catch a glimpse of her matching bra.

“You asked me… you… you said that I could come if I… ate your pussy first.”

“And what did you tell me?”

“That… I’m… not a…. That I am not into girls, Julie.”

“And what else did you tell me?”

Julie watched as her sister’s hands balled into fists and as her nipples hardened beneath her dress and as her breath hitched and her eyes fluttered and her thighs clenched together.

“That… that you’re my sister and that would be… incest.”

Julie nodded. “And incest is wrong, isn’t it, April?”

“Yes,” she replied, hesitantly

The single sound came out as more of a sigh than a fully formed word. More of a question than a statement.

“But what if I told you that was the only way I’d let you come again? Forever and ever.”

“I… I don’t know.”

Julie just smiled as she raised the hem of her skirt to show off the wet patch covering her pussy, noting how April’s gaze lingered on it and she licked her lips longingly, and she started breathing so hard that Julie actually worried she might pass out.

And then, she lowered it again, smoothing it out over he thighs.

“When you wake up, you won’t remember any of this, will you, April?”

“No, Julie. I won’t remember anything.”

“Good girl. Now wake up.”

April knelt perfectly still, resting her bottom on her heels. Her back was straight. Her thighs spread wide, exposing her pussy. Her chest was out. Her chin was up. And her hands were clasped behind her back. She was naked, her clothes carefully folded and placed on the couch. Her eyes were glassy as she focused on the sound of Julie’s nails tapping hypnotically on the desk. One. Two. Three. Pause. One. Two. Three. Pause.  She’d been kneeling there for a while, not that she really noticed.

She was masturbating. Again. Julie had told her to. Her sister. She’d thought she wasn’t into girls. But maybe she was, a little bit?  Maybe…

“How long since your last orgasm, April?”

She shuddered. She’d been rubbing her clit now for… she’d lost track. Long enough that it was sensitive. Almost painful. Because Julie had told her to. She’d also told her that good girls don’t come without permission. And that she was a good girl. And that if she wanted to come, she had to make her come first. And that incest was wrong.

“Fourteen weeks. I can’t… anymore, Julie. It’s too much.”

Julie nodded, a look of understanding warming her smile, making her eyes sparkle, making her voice soft as she slid of the edge of the desk and undid her skirt, letting it slide down her legs and pool around her ankles. And then she stepped out of it so that she was standing directly before April.

April was mesmerized. Julie had on a pair of black lace panties. They were wet, and they smelled of her. Of her arousal. Of her need. Of pussy. Forbidden pussy.

She couldn’t look away. Her hips were at eye level. She took a deep breath and inhaled her scent, filling her lungs. Her sister’s pussy.  It was wrong. She knew it. Jule had even told her so. She whimpered, shaking, her hand between her thighs, thumb grinding against her clit, two fingers curling up inside her dripping wet cunt, fucking herself because Julie had told her to.  She was making a mess on the carpet. She didn’t care. She was humiliating herself in front of her sister. She didn’t care. She was desperate to come. She’d do anything Julie told her to.

“Say it out loud, April.”

She swallowed, tilting her head back, staring up at Julie’s hazel coloured eyes. And her plump lips. At her triumphant smile.

“I need to come, Julie.”

“And how do you do that?”

“By being a good girl. By… by eating your pussy?”

“But you aren’t into girls, April.”

“I don’t care,” she whispered, shaking with desperation.

“And incest is wrong.”

“I don’t care,” she said, forcefully, her decision already made. “Please?”

She watched as Julie hooked her thumbs into her panties and pushed slowly down, peeling them over her slender hips, partway down her thighs, revealing her neatly trimmed pussy.

She started, transfixed by the sight, her first sight of…  her sister’s cunt. No, not her first. Growing up, she’d seen her naked. They both had, but not this way. This was different. April was mesmerized as Julie slid her already soaked panties down her thighs. Shaking as she stepped out of them and kicked them to one side, leaving her naked from the waist down, her pussy glistening, her thighs smeared and shiny and wet.

“There’s no going back if you do this, little sister.”

April made a strangled sound and lurched forward, wrapping her arms around her legs, burying her face between her thighs, lapping at her like a dog, smearing her juices all over her lips and cheeks and nose. Tasting her.  Tangy and a little sweet and forbidden. She kissed her clit, worshiping it with her mouth. She sucked it between her lips, vibrating with lust, her arms tightening as she pushed her tongue between soft wet, pink lips noisily. Slurping, the squelch loud and dirty and desperate.  

Julie was moaning, pulling her back with her, leaning her ass against the edge of the desk, her hand settling on her head, fingers gripping her hair, smothering her against her dripping wet cunt, whispering words of encouragement. And then…

“When you wake up you will remember everything, April. Understood?”

Her words were smothered by her sister’s pussy as she drove her tongue deeper, feeling it clench, cunt juices running down her chin.

“Wake up, April.”

She woke, became aware, remembering everything. The first time Julie had hypnotized her. All the times she’d edged her and denied her to orgasm.  All the longing and the desperate need. But mostly, the promise. Make her come, and she’ll let me. And she wanted to so badly, Julie had promised.

She felt it. Felt her shaking as she pushed her over the edge. Felt her walls clench and her clit pulse and her fingers tightening.  Felt and tasted her cum as it filled her mouth. Felt herself surrender as she drove her fingers into her own cunt, tears rolling down her face as Juie let out a soft cry and climaxed. And then, so did she.
