We Shouldn't Have Done This

- The other part of me liked it...

His confession sent an intense shiver down my spine. My excitement took possession of my body. I opened my mouth before refusing to say the first thing that came into my head. I didn't want to rush her.

- I couldn't stop thinking about it all day yesterday... I confessed, my voice distorted by the desire for intimacy with her.

- I'm not completely comfortable with the idea, but... I feel like I'm brushing against the forbidden. Right now, I'm feeling needy, lonely, eager to discover new things, she whispered, more to herself than to me.

- You know you can trust me...

- I know, Max. But whatever's on your mind right now, I can't satisfy it. At least... not now. However...

- However?

She turned to me and came close enough for me to feel the warmth of her body. We were back to the days of adolescent pillow talk. This complicity made my heart beat even faster. The idea of discovering her thoughts, her fantasies, her desires, it drove me crazy.

- I think...I want us to discover each other's universe, she says with a little smile.

- How's that?

- Your world is pornography. These very visual films, these very raw images, these screams, these raw fantasies. I'm curious to find out what turns you on. Makes you hard. Makes you come.

- Hmmm... and yours?

I let out a moan of pleasure without even realizing it. Unconsciously, I stroked my sex under the comforter.

- I like to imagine things. Building my movie, the scenes, the characters, the acts. I can explore all sorts of impossible things, play out my most unspeakable fantasies, because my mind knows no bounds.

- It's all very tempting...

- I need to think about what I'd like to do for my world...but tonight I'd like to start with yours...

- What do you have in mind Emma?

- Why don't you give me a guided tour of your favorite categories on the naughty sites? I want to see you enjoy yourself. It'd make me feel more intimate with you, without us having to...well...you know?

- I understand, I'm not going to turn my back on that, even if it will be the first time I've jerked off in front of a girl.

- You've got to start sometime... she concluded with a mischievous smile.

Her eyes sparkled in the pale light projected by my smartphone. I didn't need to start any film to feel like coming already. The temptation was even stronger when she nestled her head in the hollow of my neck and let her hands caress my torso with sensuality and tenderness. I entered the address of my favorite X site, trying to disperse my attention on all the crude images unveiling themselves before my eyes. She scrolled through the various categories with me, without really learning anything. Emma listened to me, without saying a word, complicit and curious.

- Ah, that one looks expensive, she laughed, pointing to a white woman in a threesome with two black men.

- It's not really my style, you see, the "Amateurs" category is more natural.

- Let me see.

I scrolled through the videos in the section and stopped on the thumbnail of a girl my age, seemingly performing oral sex on her boyfriend. Instinctively, I clicked on the video and it launched into music.

- The famous iconic jingle of your wild nights... teased Emma.

- But alas!

The action began unscripted. A couple about my age stood in a brothel-like bedroom, their sheets unraveled. The film was of very questionable quality, which reinforced its realism. They kissed, and then the man quickly grabbed the smartphone to film his girlfriend's face, undoing his pants. His hardened sex came out of the box like a devil, slapping her slim face a little as the couple laughed at the awkwardness. His tongue darted back and forth over the erect penis, glans within reach of his mouth, quickly swallowed greedily. Her blue eyes fixed on the camera, you could feel the desire and love she had for the lucky man enjoying this treat.

I began to jerk off, a little uncomfortably. I still had the comforter over my lower body. Emma looked at me, mischievous in her eyes.

- You know, if you're going to hide, you might as well do nothing.

- I'm sorry, I...

I tossed the rest of my comforter at my ankles, revealing my hardened sex in my hand. Emma looked at him, still resting her head against my shoulder. She was barely looking at the screen. It was the silhouette of my sex in the half-light that interested her.

- Have you ever had your dick sucked? she asked.

- Once, for a few seconds, with her. I don't think she was very keen on the idea.

- It's a pity... I can tell it turns you on.

- Indeed, it's a bit of a fantasy of mine.

The film speeds up, the girl gets down on all fours and her boyfriend licks her roughly. The camera narrowly avoids contact with her already moist vulva. I can see the full relief of my badly waxed sex, and let out a moan of pleasure. Emma slides her hand over my belly, then up my thigh. Finally, she grazes my balls, the inside of my legs, then moves up to my sex. Always with her fingertips, with a certain elegance, a controlled expectation. I lost interest in the film for a few moments. She whispered in my ear. Her warm breath passed along the back of my neck, making me tremble.

- Do you want me to make you happy?

- I'm dying for it...

Her touch became more conquering. She clasped my sex in her warm hand. And slowly the back and forth began. I struggled to watch the film, oscillating between the doggy-style in progress and Emma's gaze on me. I looked at her lips for a moment, hesitating to kiss her. But then I thought better of it. My mind reminded me that this was my sister I was playing with. A dangerous game. I couldn't see myself showing her such feelings... Our moment was more a curious experiment between two beings who could trust each other completely than a desire for love...

- I love feeling the pleasure pulsing through your cock. It's bigger than I thought.

His tone, more raw than ordinary, surprised me a little.

- Thanks... you're really doing me good here...

- That's the point, Max. Enjoy it.

The film gained in intensity. The protagonists moaned with pleasure. I could see the girl's lovely buttocks being taken over by that naked sex, sliding into her rapidly, more and more savagely. The tasty mix of my cerebral arousal and the physical stimulation from Emma's hand brought me to a peak. I held back in-extremis.

- You weren't far from coming, were you? she said, a little offended.

- Yes, but it's too good, I don't want to stop.

- All good things must come to an end Max, let yourself go... she whispered to me in a warm whisper.

The film ended with the vision of this beautiful girl, her mouth open, welcoming her boyfriend's hot, abundant cum with an amused look. She then sucked religiously, swallowing his semen and swallowing loudly, before showing provocatively that not a drop was left.

- Oh fuck... I let out, sensing that I was not far from a new peak of pleasure.

- I can see better what you like...

Emma left my shoulder, sending a look both amused and full of lust at my face, like a punch. She placed her lips on my chest and made her way down to my belly and thighs. Her hand jerked me off with greater speed as she slid her wet tongue along my sex in a much better simulation than in the film. I squirmed, both with impatience and fear. It would take so little for me to ejaculate uncontrollably on her face. Emma seemed to be enjoying my struggle, gently sliding my glans between her lips. An ecstatic moan escaped my lips. The torrent of pleasure from her hot, wet mouth had me clutching the sheet.

- Emma I...I can't hold back...it's so good...

She went on for a few seconds, then stopped for a moment, giving me another look somewhat masked by the half-light. Her warm, sighing voice put me in a trance.

- What makes you think I want you to hold back?

Then she impaled her mouth on my sex, making me feel her deep throat, the most sensual and delicious suction in her arsenal, this orgasmic dance accompanied by her wild, swift hand to overcome my last resistance. I felt the pleasure soar, intense, imminent, ejaculating two hot, abundant first jets right into her mouth. The third, smaller jet drenched her chin, dripping down her neck. My overly copious ejaculation dripped in part down my thighs. I could feel her look of satisfaction on my face. She began to lick the rest of my hot semen from my testicles. Emma climbed back up, grabbing a handkerchief to wipe her smeared skin.

- Well...you've done me, she laughed, coming up beside me.

- Shit, Emma, that was, wow. I'm sorry, I didn't think I had that much.

- It wasn't unpleasant. It was short, but you were so excited, I'm surprised you didn't crack before, just with my hand.

I was slowly coming to my senses. I wiped my sex before turning back to my sister, who had resumed her place on the bed.

- It was really incredible, I confided, still on cloud nine.

- I don't know if I'm horribly embarrassed by what I've just done to my own brother, or oddly satisfied to have satisfied his impulse.

- I hope you don't regret it...

- We'll see... that's not the case at the moment.

Her playful, naughty temperament retreated behind her usual mask of reason. I felt her pensive, her eyes vague. The calm of the night lowered my excitement. I looked at Emma's body, which seemed just as desirable as last night.

- Emma?

- Yes?

- Why don't we explore your world now? I don't want to be selfish.

- You're right not to be. I don't mind...

- What did you have in mind...?

- Oh well...here...I'll explain...

We shouldn't have done this, and yet...
