It probably goes without saying that the relationship between my sister and me has been somewhat fraught at times. I know that sounds like a vast understatement, with all three of us standing naked in a NYC hotel room in the middle of the night with my husband watching. I admit I’m not entirely blameless for how things turned out. But my sister is mostly responsible.
First, there is our age difference. Sometimes people mistake us for mother and daughter. I’m not going to reveal how many years separate us, but I got a lot of babysitting duties when she was little. In some sense, I was often like an actual ‘mother’ to my little sister when we were growing up. Our mom often took advantage of the age difference to use me for free babysitting hours. My sister did not always appreciate it. Many times I heard her scream, “YOU’RE NOT THE BOSS OF ME!” during a temper tantrum when I was left in charge. She’s repeated that sentiment to me in less strident terms in our adult years when I’ve tried to offer well-intentioned guidance.
She also resented my position as the favored ‘perfect’ daughter in our parents’ view. She fell into the role of ‘rebellious’ daughter by default. She came to enjoy that role: Staying out after curfew, dating the wrong boys, smoking pot, etc.
She also made up lies at my expense. Basically, using actual facts with her slanted version of events to make me look bad, while I was the one on the defensive, coming up with explanations that sounded lame and less truthful. Fortunately, there hasn’t been an opportunity for her to pull that stunt on me since we were teenagers.
I’ll admit I also broke the parental rules at times. But I usually seemed to get away with it more often. That fueled her jealousy even more. So hearing my tale about meeting John, launching into an affair with zero consequences because my husband wants me to get laid, and this new lover also has a cock the size of the Washington Monument, apparently dredged up a ton of resentment that quickly boomeranged back on me with her sudden appearance at my door.
She always had a very competitive streak, trying to prove herself by outdoing me in everything from playing Candyland as kids to who was the better high school athlete. We both ran on the track team in high school; she was a few years behind me, of course, but she ALWAYS made a point of letting me know when she broke one of my records. And of course, the constant borrowing of my favorite clothes for dates without asking. I even found a cum stain once on a mini-skirt she borrowed! But now, as married adults with our own families, I had assumed those conflicts were long past.
And there is her younger, tight, perfect body. Her tiny, perfectly round ass. Her smaller perky, round, non-sagging breasts with those oversized nipples. I had never seen her naked until now, but it wasn’t hard to imagine those attributes whenever she wore revealing clothes. Whenever we’re together in public, I can see everyone’s head turn in her direction, and folks will even tell me what a lovely daughter I have! Which, of course, makes her laugh out loud. I know that sounds petty, but I can’t help it.
The moment my sister dropped her trench coat to the floor, I instantly regretted a decision I had made an hour earlier, long before her knock on the door. I had felt an anxiety attack coming on. I knew it was being triggered by the looming video call with David because he would actually be watching us having sex.
I had taken one Xanax, long prescribed for my social anxiety, which I occasionally experience. It works very well, giving a calming, soothing effect every time. The downside for me is the disinhibiting effect it can have on behavior, one of the numerous warnings included in the instructions:
“The sedating effects can sometimes lead to paradoxical sexual disinhibition—lowering inhibitions, dulling judgment, and causing impulsive or atypical sexual behavior.”
Not a problem in the security of my own bedroom at home with my husband. But in a hotel room a thousand miles from home, with my lover standing naked in front of me with a throbbing erection? My husband watching? My sister standing before us equally naked and posing as provocatively as possible? The timing, the location, and the four of us together were more than enough to launch anyone into ‘atypical’ sexual behavior. But the Xanax made it certain I would be the most enthusiastic participant.
I knew right away that my ill-timed decision to drop my dress was the first sign my thinking was already impaired and my ‘atypical’ sexual behavior was kicking in. I was sure my sister wouldn’t do anything to restrain my impulses tonight. She has known about my social anxiety, my Xanax prescription, and the potential sexual side effects on me for years. If I admitted taking it now, she would use the knowledge to exploit this situation even further. If I didn’t tell them, I would be the most willing participant in whatever happens tonight. I felt trapped in a ‘Catch-22’ situation. My rapid breathing appeared more like increased arousal than the last stages of my original anxiety.
“John, this isn’t what you think it is. I didn’t ask her to come here. She just showed up unannounced! You can see she’s drunk!”
It was my sister’s turn to smirk now. She crouched down to pick up her phone from the pocket of her coat on the floor, taking care to keep her breasts and pussy in full view of John at all times.
“Of course she invited me! Why else do you think she sent me these pictures of her holding your cock?” She held up her phone for John to prove her accusation. That proved I was the sender, but I never intended for her to show up unannounced.
“Did you really send her those pictures of me?” Once again, he was looking at me as if seeing me for the first time, though not in a good way. I was caught totally off guard. She was really giving off a smug, self-satisfied expression now. It was useless to deny her accusation. How else would those end up on her phone?
“Well, yes. I did. But, really, it’s not what you think. It was just a joke. She asked me to send those.”
This wasn’t sounding any better. My breathing was getting ragged from my rising panic that this was only going further in the wrong direction. It felt like my butt plug was bulging to phenomenal dimensions inside my ass. Every muscle in my pelvic region seemed tense and tight in anticipation of where this might lead. But by now, the Xanax was performing its additional, unprescribed role as a muscle relaxant. Whether I liked it or not, my body would be much more responsive than usual. I wasn’t sure how much worse this could get. John was doing his best to understand.
“She asked for pictures of my cock, and you went ahead and sent them? That doesn’t sound like a joke or an unplanned visit. It sounds more like an invitation.” It was happening all over again. She takes some actual facts, then adds her own twist to work against me.
My sister’s expression was as smug as ever as she crossed her arms under her tits, propping them up in a perfect display that only seemed unintentional, but was fully intended to be as provocative as possible to John.
“Can’t you see? She’s just twisting things around to make me look bad and get you to fuck her, that’s all. I had no idea she would actually show up here.”
Actually, I had no idea what she had planned when she showed up here. I just didn’t want to give her the chance to find out. I just wanted to make sure she left, the sooner the better.
“You thought taking off your dress as soon as I walked in was the best way to convince me you weren’t planning something totally kinky tonight?”
My sister couldn’t help chiming in.
“That’s right, you should have heard her planning it with me earlier today. Naturally, I was a bit reluctant to go along with her idea to have a threesome with you. But she kept insisting, but when she showed me those pictures of your cock. Well, what could I say? I just had to come here after an invitation like that!”
Threesome? I couldn’t believe what I was hearing. I put my hands over my ears and shut my eyes to block out her crazy, self-serving story. She’d been standing behind me all this time. When I closed my eyes and covered my ears, she took the opportunity to take me by the shoulders and turn me around so John was looking at my backside. Especially the sparkling round base of my butt plug.
“See? She even told me she was going to be using her anal plug tonight to please you and herself during our threesome! She said she was using it to train her asshole for anal sex with you. She bought a bunch of extra lube so you could end her anal virgin status right in front of David!”
What? I couldn’t believe how she was making all this up. And worse, it all sounded 100% plausible with my newly purchased sex lube sitting on the nightstand, and the unexpected appearance of the butt plug. Her ‘lying game’ was working to perfection.
John was certain he fully understood the situation now, thanks to my sister.
“It’s ok, babe, I get it. It’s perfectly natural for you to get cold feet at the last moment. Especially after all the planning and preparation you put into tonight’s special event. We were taking a big step in letting David watch us, and it only makes sense you’d want to go this extra mile. Now that I understand what you and your sister planned for me tonight, I’m totally flattered! You’re amazing!”
“Of course, what else is a sister for?” She asked with all the sincerity of the worst used car salesman ever.
That’s when they both gently took hold of my forearms to lead me toward the bed. That was all it took. The skin-on-skin contact was the last trigger my body needed to finally let go of all restraints. I lay back on the bed willingly as all the tension my body had been holding in for the last few minutes of arguing instantly melted away. Nothing but an overwhelming sense of relief and calm flowed over me. The Xanax was now fully in control and relaxing me just as it was prescribed for. And also with the unintended effect of triggering every aspect of ‘atypical’ sexual behavior it could unleash. I closed my eyes.
Someone’s lips and tongue were working on my breasts and nipples. My mind drifted back to my early motherhood, nursing my babies in the middle of the night in my rocking chair. I would often be rewarded by a series of ‘mini-orgasms’ while breastfeeding since my nipples were so sensitive. This set of lips and tongue was so good that my hips were starting to rock in rhythm with the sucking and the flicking action of that tongue, plus the hands that held and squeezed them gently. I could tell I was building toward a very nice orgasm. Especially since another tongue and pair of lips were expertly working on my throbbing clit and labia with precision: entering, withdrawing, circling, sucking, licking, and flicking.
As my brain processed the fact that I was being pleasured by two different people, I slowly opened my eyes from my dream-like state to see who was doing what to me. Oh, yes, it was John giving my breasts such loving care. And of course, it was my own extremely pretty, sensuous daughter between my thighs, expertly working my clit. But wait, I don’t have a daughter. Of course, that’s my sister bringing me closer and closer to my climax!
MY SISTER! THIS CAN’T BE HAPPENING!
As the realization hit me, our eyes locked onto each other, and I could feel her mouth turn into a wicked smile across my pussy as she used her hands to hold my pelvis down firmly to the bed. She ordered John to hold me down as well because I was getting close to climaxing. His hands moved from my breasts to my shoulders to keep me pinned, but his mouth kept up the perfect attention to my breasts that was still driving me wild.
Just as I was about to cum, my sister backed off, leaving me in a frustrated limbo. Then she started in again, bringing me closer again. This time, I called out to her not to stop. I’m so, so close! But she backed off again! I knew exactly what she was doing now–edging me again and again until I begged her to make me cum. Normally, I would have fought against my sister’s sick manipulation of my mind and body. But now? My Xanax induced state loved every second of what she was doing to me in spite of the building frustration. My body was starting to feel like a dam getting ready to burst.
A mix of conflicting emotions swirled in my brain. My body was experiencing incredible peaks of pleasure, being delivered by her as my mind rebelled at the idea my own sister was taking delight in tormenting me this way. I was being forced to beg for mercy from my tormentor. Mercy could only come in the form of her letting me climax. It was the ultimate humiliation this little sister could inflict on her big sister. That taut wire from my clit to the base of my brain stem was being pulled tighter and tighter every second by her.
My excitement and acceptance of everything they were doing was apparent to them. The butt plug was adding its magic to every sensation rippling through my pelvis. They no longer needed to restrain me. John’s hands were kneading my breasts again as he sucked my nipples up into his mouth with more intensity. I buried my fingers in her hair, holding her face against me, making certain she could no longer back off. No longer holding me down, she was free to insert her fingers rapidly in and out of my vagina while keeping up her tongue work on my clit. I was holding her head tightly enough to smother her. She would be forced to make me cum if she wanted to breathe. No more edging or teasing me now. Big sister is going to be the boss at last, whether she likes it or not.
My hips bucked uncontrollably as one of the most intense orgasms I had experienced started hitting me. It began with my trembling legs, a continuous shiver traveling upward through my torso and into my arms. It felt like every vein in my neck and face was bulging out, ready to burst. I couldn’t stop myself from letting out a primal scream. A scream indistinguishable from agony or ecstasy. It was happening all over again. I saw stars circling around the room as I blacked out, this time with my body going rigid for a few seconds before I passed out and collapsed.
As I recovered, I could hear the sound of muffled voices, as if from a distance. John was attempting to reassure my sister.
“It’s ok. This happened last night. She’ll be ok in a few minutes. One of those ‘la petite mort’ orgasms. But she’ll be out of it for a while.”
“Wow. I’ve never had one of those myself, but I’ve heard of them. She even has better orgasms than me! Good thing she’s going to be out of it–it makes it that much easier to get her ready for round two.”
“Holy shit!” Came from my phone perched on the bedside table as my husband rendered his verdict on what he had just witnessed.
John and my sister rolled my limp body over on my side. I felt her fingers take a firm grasp on the base of the butt plug. I was pleasantly surprised by the care with which she gently turned and angled the plug out of my anus. It definitely felt as if my anus was still slightly open, or at least looser than an hour ago. I was tempted to reach down and check for myself. Before I could, my sister had already pumped a liberal amount of lubricant from the container on the bedside table. My body gave an involuntary shudder as she shoved a glob of it into my asshole with two fingers. She repeated the insertion two more times, her fingers exciting me a little more each time as my body shivered in response.
After putting it inside me, she pumped out even more lubricant onto her hands. I heard John’s soft moans of pleasure as she ran her hands up and down his cock, slowly spreading the lube the full length of his quivering shaft. His cock was as hard as I’ve ever seen it.
“She’s as ready as she’ll ever be now. But she’ll still be tight as a fist,” my sister announced proudly.
All I could think was, yes, I will be that tight. And yes, I am ready.
