Our Little Secret: My Boyfriend’s Little Sister (FF, oral, cheating, public)

I have a bit of a “thing” for my boyfriend’s sister.

And by thing… I mean I want to pin her down, strip her naked, and bury my face between her legs until cums.

And no, I have no idea why. Hell, I don’t even know when or how. Raven was always the cute little sister I never had. Adorable. Nice. Fun. We’d talk all the time, even without my boyfriend present.

Then one day, something just… changed.

We were getting brunch, and hardly even one mimosa in, I wanted to run my tongue across every inch of her body. That cute, bubbly girl I only saw at family functions was now a sweet treasure that only my wildest fantasies could satiate.

The only thing on my mind, day in and day out, was being in bed with her.

We couldn’t go shopping without me staring at her ass and legs. She did have a small booty, but it was so cute and perky! (After all, pancakes are cakes too!) Whenever she posted on her Instagram, I found myself staring at her pictures for hours, drawn to those perfect tits, a department she was very blessed in.

As if that wasn’t enough, she had a gorgeous face, piercing eyes, and a smile that genuinely lights up rooms. She was a candidate for winning the genetics lottery, honestly.

No other woman has driven me to this point of insanity like she has. Everything about her drove me wild, from her sense of humor, to how she eats, taking super small bites, to how she dresses perfectly for any occasion.

Lusting after a woman isn’t new to me, I’m bisexual and have been eating pussy basically since high school. Approaching women or men didn’t intimidate me in the slightest. If I wanted them, I’d go up to them. My boyfriend knows this, as he just happened to be in the right place at the right time, because I could be with anyone I wanted.

Right now, what I wanted just happened to be his sister.

“Are you doing ok, you’re getting spacey again?” Raven turned and asked.

*Oh that’s right, we were at the mall.*

Her legs underneath that yellow sundress was making me salivate and space out thinking about them being on the sides of my head.

“See something you like?” she giggled. “This dress doesn’t look that good for you to be staring so hard.”

*It’s what’s under it, but damn she was filling that thing out.* “Sorry, Spaced out for a little bit there.”

“You’re such an airhead.”

I shake the lustful thoughts out of my head to try to recover. Probably doesn’t work as well as I think it does. “My bad. Saw the tattoo shop and was thinking of my next one.”

“Oooo! I was thinking of getting a few piercings done. Do you want to stop by?”

“Nah, not now. What were you thinking about getting done?” I ask.

“Well, my friend got her vagina pierced, but I was thinking about getting my nipples pierced.”

My mouth waters thinking about her perfect breasts having a sexy piercing and my tongue playing with them. “Well, I got mine done.”

“Really?” Her eyes widened. “I didn’t know that! How was it? Did it hurt? How much did it cost? Did anyone go with you?”

“Relax, Raven.” I laugh. “Not like I could tell you over family dinner. Did you want to see them?”

“Only if that’s ok!”

My brain manages to push away the thought of her naked well enough for me to find a clothing store’s changing rooms for me to dip into. Perhaps it’s only because I get to be alone with her in a changing room that my brain thinks so clearly.

I lead her into the nearest store, *Aerie*, and grab a handful of random shirts off the rack on the way to the changing room where we both crowd into a spacious booth. My heart feels like it’s smashing against my chest. I have her full attention, and fully indulge in the taboo. Whether I’ll have this change again or not doesn’t matter. I’m too obsessed to think straight.

With her eyes on me, I take my shirt off, and do the same with my bra.

Her eyes become as wide as dinner plates, and her jaw drops while she stares at my breasts. Admittedly, they aren’t nearly as perfect as hers, but I’m proud, so whatever.

“See something you like?”

Her face is enthralled, and there’s something going on in her head. This isn’t just me showing her something she wants done, this feels like something more. The sexual tension grows past a point she can no longer ignore.

“Sorry…” she stammers. “I’m just… they look great. You look great. Just… wow.”

I’m getting so wet with anticipation I think I might die if I leave this booth and neither of us has a release. Her cute face tells a story of the gears in her head spinning at a pace the rest of her body is struggling to keep up with.

“You can get familiar if you want.” I tell her.

She seems to want to retreat into herself. “Oh, n-no i don’t think i can.”

I tease, only because I feel that if her fingertips grazed my nipples, I’d orgasm. “You don’t like them?”

“No, i mean yes! I do, I think they look great. I just–”

I take her hand and place it right on my bare breast. Her fingers send shivers up my spine, and make my clit vibrate with a fury. My hands control her movements, fondling my pierced b cups.

Slowly, I raise my hand to touch hers, lightly feeling them through the soft fabric. Other than her breathing becoming more audible, she’s still. I can’t tell if it is the thrill, her wondering about the taboo of it all, or maybe she’s focusing on the light touch of my skin.

I ask, “Is this something you like?”

The words are stuck in her throat. “I– I…”

I plant a kiss on her chest, then another. Then another. She gasps, and then sighs in satisfaction.

“I think I do,” she says.

I kiss her lightly on her neck, brushing her hair back with my off hand, while the other still guides her hands full of my breasts. Her hands move of their own accord now, gently running across my nipples. Mine grip her waist, and move her body closer to mine while my lips travel across her beautiful cleavage and her neck.

“I’m not sure…” she moans like she’s about to finish. “I’m not sure we can-”

“This can be our little secret ok?” I bite on her collarbone, and she shudders.

“Our little secret.” she moans.

We kiss each other fiercely, the deepest most visceral tongue kiss we could muster. Her body melts into me, giving as much of herself to me as she could. Raven’s hands travel all over my body, and my skin hungers for more of her soft palms all over it.

Her clit calls for me. I respond with no hesitation.

My fingers massage her sweet pussy between her thighs. My fingers are soaked within seconds, and I realize how badly the dress needs to go. I fall to my knees, spread her legs, and dart between them.

That gorgeous slit awaits me, and my tongue received a wonderful mouthful of sweet honey before I truly got underway on her clit. She tastes even better than I imagined she would.

She throws her head back and succumbs to my tongue. I feel her legs starting to shake, her back arching, moaning for me. At this moment, she was mine.

My soft kisses turn into a makeout session, and she writhes under my control, her fingers holding onto my hair for dear life.

*“Oh, shit!”*

Her hips buck against my tongue, fucking my mouth. Those sexy toned legs were tensing, those toes were curling. Her hips could not stay in place. She was losing it. I can tell easily she had never been pleasured like this.

Time to show off. I curl my ring and middle fingers inside her tight walls, her tight pussy pours down my hand and wrist.

*“Unh! OhMyGod!”*

Her thighs tighten around my head. The combination of my rhythmic massaging of her clit, and my fingers inside her are bringing her to the point of insanity. I loved every second. My ego was getting stroked as well as her pussy, and I’m dripping wet.

She quickly covers her mouth with her hand and moans into it. *“Right there! Right there!”* Her muffled cries made me climax while I was licking her up.

I come up for air, “You gonna cum for me?” While I’m fingering her tight pussy.

Words don’t escape her lips, her moans of pleasure are in the way. A good problem to have. She can only nod.

*“I want it now.”*

She obeys like a good girl. Immediately, she cums harder than any girl I’ve been with. Her body collapsing under the weight of the tidal wave of an orgasm she has is like a drug. Raven’s vagina throbs around my tongue and fingers. Her orgasm is so powerful it feels like I have one of my own.

I couldn’t be more proud of myself.

I retreat with a smile, and she slowly tries to pull herself together.

“Holy… shit.” she breathes. “I have never. Ever. Had that.”

“Never been with a girl, huh?”

She shakes her head. “That too, but every orgasm I thought I had wasn’t an orgasm. Now I think I’ve never cum until today.”

As if my ego needed to be inflated. But also, poor girl. Such a shame that she’s had sex a handfull of times, and never an orgasm. Her previous partners were appetizers. I was the meal.

I lick the creamy white orgasm from my fingers, “Oh honey. If you ‘think’ you haven’t finished, then you haven’t finished.”

Feeling like I’m the one who just finished, I put my bra back on, and replace my shirt, while she fixes her hair in the mirror. My fantasies run wild thinking about how many changing rooms we can fuck in before we were kicked out of the mall.

“Let’s hurry.” she snaps.

“Afraid we’re going to get kicked out?” I joke.

“No.” she calmly replies. “If we get back to your apartment fast enough, we can do that a few more times before my brother get’s off work.

With no further words, we power walk out of the store, sprint to her car where she drives 20 over the speed limit back to my place. There, I am in heaven while we fuck each other senseless until we can’t move anymore.
