My Friend Monica And My Aunt

It was my (M18) senior year, the weekend after my eighteenth birthday.

My parents had let me throw a party at our house, and the place had been packed for hours with friends and music.

They were out of town for two weeks on a work trip, which left my Aunt in charge of the house. She had lived with us for years after the death of her husband back in Japan, so it wasn’t unusual for her to be the one keeping an eye on things.

My Aunt (who we’ll call “Mio” from now on) is full Japanese, born and raised, small and petite at just over five feet, maybe five two at most. She’s honestly very beautiful. Even in her fifties she has this almost doll-like look, with smooth skin and almond eyes that always sparkle when she smiles.

Her body is slim but fit and really curvy, shaped by her years of weight lifting and Pilates.

All night she floated around the party, talking with the girls in my friend group, hopping into photos, laughing, having some drinks, and being playful. She was definitely the “cool” mom that night.

By the time things started winding down, the crowd had thinned until only a handful of people were still lingering.

Eventually even they left, everyone except for my friend Monica.

Monica was one of my closest friends. She’s pretty tall, around five eight, white and slim, with long blonde hair. Her body had that lean, athletic tone you could tell came naturally, her arms and legs subtly defined, her hips giving her just enough curve to stand out. She had that classic American prettiness that never felt forced.

Despite her looks, there was always an innocence about her. She wasn’t a huge partier. She didn’t drink or smoke much, but she loved hanging around while the rest of us did.

Monica had been coming around my house since seventh grade, and over time, she and my Aunt had gotten almost as close as Monica and I were.

My Aunt would hug around her waist in this cute way and joke that Monica was her “only daughter,” and Monica would always play along, calling her “my other mom.”

It was sweet, and it made me feel good about the people I chose to keep close.

That night, Monica couldn’t find a ride home, so it ended up being just the three of us.

My Aunt told her she could spend the night, but she teased her, half joking, half serious, making her promise that she’d stay downstairs.

“You two are not staying in the same room, you’ll just get into trouble,” she said in her cute accent.

We all laughed, because to us it felt ridiculous. Monica was pretty, sure, but she was also very innocent, and our friendship had never been anything more than platonic.

After helping clean up a little, I went upstairs to get ready for bed. I could still hear Monica and my Aunt talking downstairs, their loud, excited voices bouncing softly through the open living room.

They sounded like they were having fun, their laughter rising now and then, stories spilling out without pause. I smiled to myself and let them be.

It was around one in the morning now. Lying in bed with my window cracked open, I smoked a little and let the cool night air wash over me. The voices below dulled into background noise, fading into the night, and eventually I drifted off.

I don’t know how long I slept, but when I woke the house seemed quiet. Or at least at first I thought it was silent, but then I noticed something faint seeping through my closed door.

It was muffled, steady, and rhythmic. I couldn’t place it at first.

Curiosity stirred in me, pulling me upright. I walked over to the door and pressed my ear against it.

When I pressed my ear to the wood, it struck me all at once. The sounds weren’t voices. They were moans.

And not just any moans. They sounded like my Aunt. Deep, breathless, slipping out uncontrollably.

Confused and unsettled, I turned the knob as quietly as I could and cracked the door open, easing it until the gap let the sound spill through clearer.

My pulse quickened. My feet moved down the hallway almost without thought, each step cautious and quiet until I was only a few feet from the railing that overlooked the living room.

Our house was pretty big, with high ceilings and an open layout that revealed the entire living room from above. From the upstairs hallway you could lean over and see everything below.

Directly under the railing sat our massive L-shaped couch. The very spot where Monica should have been asleep.

The moans were mixed with something else now. Wet, sharp smacks. The unmistakable sound of skin meeting skin, layered with faint shushes, as if someone was trying to calm her.

For a split second my mind scrambled for explanations. Monica was supposed to be sleeping on the couch, wasn’t she?

My curiosity pushed me closer, overriding the warning in the back of my mind. My heart pounded, my throat tightening as I edged forward and leaned slowly over the railing.

The moment my eyes caught the scene below, I froze in shock.

Directly below me, Monica sat slumped into the couch cushions, her legs spread wide. Strapped tight around her waist was a short, thick, life-like strap-on, sticking rigidly upright.

And there… sitting in her lap with her back facing her…was my aunt. She was squatted low, back arched to the limit, head dangling forward, her ass pushed back out as she bounced up and down onto Monica’s lap.

Every drop of her hips landed heavy. Her cheeks jiggled and rippled with each impact, grinding and clapping against the strap as she rode.

From my angle above, not directly overhead but slightly behind, the view was completely unobstructed. Both of their backs were turned toward me, leaving everything exposed.

Mio’s slim waist funneled tight, her hips flaring wide, her round ass spreading and swallowing the strap inch by inch.

The sounds carried up clearly in the open space, wet smacks of skin on skin, Mio’s breathless moans, Monica’s soft gasps, all echoing together until they filled the living room.

I gripped the railing, my palms clammy as my eyes stayed locked on the way her body moved. Each bounce rippled across her ass, dimples flashing as her cheeks smacked against Monica’s pelvis.

Wondering where the strap-on even came from, my eyes widened as I watched her bounce and plant down firmly, in a constant, hard rhythm.

It was unreal.

Mio’s hands gripped Monica’s knees to steady herself as she rode restlessly. Like she was giving her a lap dance, twerking up and down, ass clapping in quick, messy rhythms.

Monicas knees struggled to stay planted, due to all the pushing, pulling and bouncing my Aunt was doing.

As she rode, Monica’s grip shifted, sliding to Mio’s hips, guiding her movements, sometimes pulling her down harder so her ass jiggled violently against her lap, other times spreading her cheeks wide to watch the strap disappear inside her.

Her petite but plump hips and ass rose above Monicas hips before she dropped it down, her ass jiggling and shaking because of the collisions.

Whenever shed moan too loud, Monica would shush her sensually, saying “Don’t stop” scratching and tickling up and down her back simultaneously. Coaxing her through every trembling bounce.

Overwhelmed by the sensations, every so often, Mio would abruptly plant herself down mid-bounce, her legs trembling as her hips rocked violently, letting out a quivering moan.

In response, Monica stabbed her hips upward, holding My Aunts hips in place, pushing her lower back forward, forcing an arch, working subtle little hip rolls to urge on more bouncing.

Mio turned her head slightly, locking eyes with Monica, and shared a breathless smile before her face melted back into trembling moans.

Mio’s ass dimpled in pulses, flexing together and apart, grinding against the strap-on, her hips continuously bucked and spasmed wildly.

The dim lighting exaggerated every detail. Shadows traced across Mio’s curves, every crack and crease outlined, making the jiggles and ripples even more intense to watch.

I stood frozen, heart racing, torn between shock and arousal.

The wet claps, the cries, the sight of her body trembling and overwhelmed, it was too much.

I felt a rush of conflicting thoughts, half of me screaming I should be stoping this and the other yelling that I shouldn’t be watching.

But then id focus on them again and see my Aunt was completely lost in it, overtaken by the rhythm, melting into every thrust.

And Monica, calm but commanding, kept her locked in the ride, pulling more and more out of her with every hump.

Mio’s movements shifted suddenly, her body giving in to a deeper rhythm. She began bouncing faster and harder, her ass dropping with sharp, heavy claps that echoed through the room.

Each time she came down, Monica thrust upward to meet her in the middle, the impact sending wild ripples through her cheeks, spreading them apart before they collapsed back together.

The pace grew frantic, desperation written in every twitch of Mio’s body. Still Bouncing, she squatted low, keeping her arch, she bent forward even more, lowering herself until both hands pressed against the floor.

From this angle her ass looked unreal, round and high, spreading wider with every bounce. Each drop made her cheeks clap and tremble like two perfect basketballs, the strap disappearing inside her as the waves of jiggle rolled outward.

Monica moaned beneath her, one hand slapping across Mio’s ass with a sharp crack, the other gripping her hip hard to keep her steady.

She drove up harder into her, eyes locked on the sight of Mio’s ass spreading wider and wider as it jiggled down onto her lap.

Their bodies moved like they were locked in the same rhythm, Mio dropping down heavy, Monica thrusting up to catch her, the collisions sharp, wet, and endless.

Mio cried out, her voice raw, her head hanging low as her arms trembled, her ass bouncing out of control against Monica’s lap.

It was escalating into something new, something wilder. Her small body was overtaken, trembling and squirming, as her moans only grew louder, deeper, more guttural.

Then, with one last shuddering cry, Mio’s whole body stiffened.

Monica caught her immediately, lifting her off the strap just enough to spin her around and guide her down onto all fours.

Mio’s legs trembled beneath her as she settled into the new position, her body shaking with the effort to hold herself up.

From above, I had the perfect view of her ass, round and high, her knees pushed wide as Monica pressed her lower back down, forcing her into a deep arch.

In that position, her hips flared even wider, her ass fully presented before Monica slid the strap back inside her.

The sound was instant, sharp slaps of skin on skin as Monica drove forward. Mio’s body jolted forward helplessly, her face burying into the cushion as her cries broke into raw, muffled moans.

Monica leaned over her, one hand pressed to the small of her back, the other sliding across her side before settling firmly on her hip. She whispered low against Mio’s ear, coaxing her through the rhythm, and I could see Mio nod faintly through her whimpers, eyes squeezed shut, her body betraying her with every trembling bounce.

Monica alternated her grip, sometimes spreading Mio’s ass wide to watch every ripple, sometimes pushing her cheeks together, grinding into her while her round ass quaked under the pressure.

Mio moaned louder, her head twisting just enough to glance back at Monica. Their eyes met, even through her trembling, Mio smiled faintly before her face collapsed back into the cushion with a desperate cry.

Monica slapped her ass with a sharp crack, then soothed it with a squeeze, murmuring encouragement I could barely hear.

Mio responded with a broken whimper and another hard push back into her, as if begging her not to stop.

Her thighs trembled uncontrollably, her hips twitching in spasms, every convulsion messy and desperate.

Monica only held her tighter, thrusting harder, forcing her through every ripple and quake.

Wave after wave of orgasm tore through Mio. It was written across her body more than her voice now, her mouth fell open in silence, the room filled only with the relentless claps of skin on skin and Monica’s heavy breaths.

Then her voice would return all at once, breaking into cries of pleasure, only to vanish again when another wave overtook her.

It repeated like a cycle. Silent, trembling convulsions. Then guttural cries. Then silence again, her body contorting helplessly under Monica’s control.

Her small frame shook violently, her ass spreading wide then clapping back together in ripples that shook all the way down her thighs.

She clawed at the cushions as if she could crawl away, but Monica yanked her hips back each time, keeping her locked in place, whispering words of encouragement.

My aunt was breaking apart in front of me, every orgasm ripping through her body, and Monica refused to let up, forcing her to surrender again and again.

What followed could only be described as a fight. Not violent, not angry, but a raw, desperate clash of bodies. It looked like a battle Mio had no chance of winning.

Monica fought to keep her in rhythm, to make her cum again and again. Mio fought to run, to crawl out from under the overwhelming waves tearing through her.

From above, I could see every frantic attempt Mio made to escape. She shuffled her knees forward, her lower back trying to straighten as her hands clawed at the cushions, crying out as if begging her body to move.

Her thighs trembled, her ass still clapping with each thrust even as she tried to pull away. Her whole body looked split between instinct and desire, desperate to flee, desperate to stay.

But Monica wasn’t letting her go. Her grip locked around Mio’s waist, yanking her back every time she tried to crawl forward, sliding her knees back, dragging her hips into every thrust.

Mio reached back suddenly, gripping at Monica’s wrists in desperation, but Monica only moaned under her breath, thrusting harder, pressing her hips down with force.

She whispered against Mio’s ear, low and coaxing, “Take it… don’t stop… that’s it.”

Mio whimpered, her voice high and trembling, her ass and hips bucking up and down desperately like she was trying to twerk the strap-on out of herself.

Her hips convulsed in wild spasms, cheeks quivering and flexing, dimples flashing under the pressure of each thrust.

The orgasms began to hit differently now. They weren’t just in her cries anymore, they were etched into her body.

She went silent as the waves overtook her, her mouth open but voiceless, the room filled only with the smacks of her ass against Monica and the ragged breaths ripping from Monica’s chest.

Then suddenly her cries would return, breaking through in raw bursts of pleasure before vanishing again, swallowed by another silent convulsion.

The cycle repeated over and over. Silent, trembling seizures of bliss. Then guttural cries. Then silence again, her body twitching, convulsing, betraying her with every bounce.

Monica whispered encouragement between moans, saying “Don’t run.” Mio’s head shook frantically against the cushions, but her body answered with another violent quake, her ass clapping harder, her thighs trembling without end.

Then Monica shifted. In one sharp move she slid her hands up Mio’s sides and seized both wrists. She yanked them back behind her, holding them like handles as she drove into her harder.

Mio’s chest collapsed fully into the cushions, her arms pinned, her back bent into a deeper arch she couldn’t escape.

Every thrust forced her ass back, cheeks spreading wide then slamming together in messy, wet claps that echoed through the room.

Mio screamed into the couch, muffled and raw, her whole frame shaking violently. She wasn’t just being taken anymore, she was being held there, dominated into orgasm after orgasm with no way to run.

From where I stood gripping the railing, I could see the exact moment she surrendered. Her arms limp in Monica’s hold, her hips twitching but no longer resisting, her cries collapsing into sobs of pleasure.

Monica held nothing back. She pulled Mio into her with every thrust, her moans mixing with Mio’s muffled screams as the couch shook beneath them.

Mio’s body broke apart again, silent convulsions wracking her frame. Her ass dimpling and flexing violently as orgasm after orgasm rolled through her.

She was done, ruined, her body betraying her over and over, her cries turning to breathless whimpers as Monica refused to let her escape.

It was the most desperate, sensual fight I had ever witnessed, Mio struggling to flee the pleasure, Monica forcing her deeper into it, until my aunt finally had no choice but to surrender completely and cum harder than I ever thought possible.

At one point, mid-thrust, Monica tilted her head up, her eyes lifting toward the ceiling. She froze for a second as her gaze met mine. From where I stood at the railing, I was caught in the open, my hand still wrapped tightly around myself.

She looked at me directly, her eyes flicking down to what I was doing, then back up to me, a faint smile tugging at her lips.

She had caught me, no question about it. But instead of stopping, she held my gaze for a long second, still driving into Mio with steady thrusts, her expression daring me to keep watching.

Then, as if nothing had happened, she calmly turned her attention back to the woman beneath her, her hunger returning without hesitation.

Her hands slid firmly up Mio’s waist, fingers digging in before sliding higher until they hooked under her hips.

With a sudden show of strength, Monica pulled hard, lifting Mio’s bottom half clean off the couch, her ass now suspended in the air while her chest, face, and arms stayed pressed into the cushion.

The effect was stunning. With her body no longer grounded, Mio’s thighs and ass lost all control. Every thrust sent shockwaves through her body, ripples spreading wildly as her cheeks bounced in loose, uncontrollable waves.

Her face buried into the couch, Mio’s moans turned guttural, shaking cries that rose higher until they broke into a desperate, gutted scream.

She convulsed, her body collapsing forward as another orgasm ripped through her, shaking her apart at the exact moment I lost control myself, climaxing as I clutched the railing.

My body jolted, my mind buzzing and disoriented as I tried to steady myself. When my breathing slowed and I dared to peek again, I saw Mio trembling in exhaustion, her body folding as she slid weakly off the strap, her back and legs quivering as if she had nothing left to give.

Her posture told the story clearly. She was overstimulated, drained, completely undone.

Panic surged through me. I stepped back quickly from the railing, heart pounding, desperate to hide before they could notice.

From the hallway, I caught the sound of her soft, breathless voice. “That was… so good. But you can’t ever tell anyone this happened.”

Their giggles followed, light and intimate, punctuated by the sound of them hugging.

I risked one last glance. They were kissing, mouths hungry and tangled, their hands gripping and pulling at each other’s asses.

It was messy and passionate, a kiss that lingered, neither wanting to break away. Finally, Monica leaned back, unstrapped herself, and gave Mio’s ass a playful smack that made her squeal softly through her laughter.

Mio swayed toward the stairs, her body trembling with every step as she made her way up to her room. I bolted back into mine, sliding under the covers just in time, my chest still heaving.

Moments later, I heard her footsteps outside my door. The knob turned slowly, the door creaked open just a crack, and I froze, eyes shut, pretending to be asleep.

She lingered there, her presence heavy, before quietly easing the door shut again and heading off to bed. Just making sure I was out.

When I woke the next morning, Monica was gone, and Mio was already downstairs, cheerful and smiling as she made breakfast like nothing had happened.

The following Monday, Monica found me alone as I walked to my car after school. She slid into the passenger seat with a nervous laugh, then apologized over and over, explaining exactly how and why it had happened.

After a pause, she asked me directly about what I had been doing while watching them.

I admitted honestly that it just happened in the heat of the moment, the shock and taboo of it all making it feel more exciting. I told her I hadn’t thought much at the time, it was pure impulse.

She surprised me by admitting that catching me watching had actually turned her on. That was why she didn’t stop.

That was why she went even further.

From there, she opened up, describing everything in detail, how it had felt from her perspective, what she had been thinking while it was happening, and why she had leaned into it.

That set the stage for what came next, part two.

…

P.S. I told Monica I was going to write a story about it, changing details for the sake of privacy. To my surprise, she grinned and told me she would write her own version from her perspective and let me edit it into shape.
