Chapter Text
You wait patiently at the wall of the dark room.
The cold air wraps itself around your naked body as you wait for your partner. You can't call out for her, due to the ball-gag in your mouth. And you can't open the door to leave the room, as your hands have been bound behind your back with ribbon.
In the middle of the room, under a spotlight, is a big leather armchair with a small table next to it. The armchair is too big for you. It's almost as if it were designed for two people.
Outside of the spotlight, the room is pitch black.
A door on the left wall opens and Kara walks in, closing the door behind her. She carried a latched wooden box with her, about the size of a shoebox.
And, while you are completely nude, she's wearing black denim jeans and white tank top.
She puts the box down on the table, and sits down in the arm chair.
"Come here."
You shuffle over to her, stopping at the edge of the spotlight.
"Are you ready?"
You nod. She smiles.
"Good girl. Come here, then."
She pats her lap. You walk forwards, but stop when you get to her.
"Come on, work with me. Don't make this difficult."
She pats her lap again and you sit down, across her legs, facing sideways. She puts her arm around you and kisses you the check.
"I've been looking forward to this. Now, turn around."
She gestures for you to turn away from her. It's awkward, with your hands restrained, but she helps you.
You're now sitting on her lap, leaning with your back against her. You can feel her breasts against your back, through her tank top.
She brings her right hand around and starts slowly rubbing your belly. You flinch at her touch and try to sit up, but she pulls you back into her.
She puts her left arm across your chest and around your neck, not hard enough to hurt you in any way, but just enough to hold you in place. It's as though her arms are telling you "don't go anywhere".
Then her right hand slowly dances down your belly, stopping between your legs. Your breathing starts to pick up, and you let out a tiny moan as she slides a finger into you. She slowly caresses you, in and out, trying to draw more moans from you. And she does when she adds a second finger. You buck a tiny bit, trying to adjust to the size.
"Oh sweety, you're too tense. You're not nearly wet enough for what I have prepared.
She adds a third finger, and you feel yourself tense up for a moment, before willing yourself to relax.
While her left arm holds you in place, her hand dances around your neck, gently pulling your hair back. She leans in and whispers in your ear.
"Do you want more?"
You're struggling desperately to contain yourself, and try to say please, but just moan through your gag again.
She smiles and adds a fourth finger, picking up her pace. You try to squeeze your legs together, but she stops you, wrapping her legs around yours. You're forced to stay in place as her finger slides in and out, faster and faster. It doesn't take long before you're moaning and writhing on her lap. You're right on the edge, and then you're past it. Waves of pleasure hit your brain as you cum, her hand slowing and guiding you through your orgasm. She relaxes her legs, allowing you a bit more freedom.
You pant desperately around your gag, as her hand slowly, slowly comes to a stop. With her left hand, she removes your gag and puts it on the table beside her. Then, she removes her right hand from you and raises it to your mouth.
"Clean."
You open your mouth and start licking and sucking your juices from each of her digits. It tastes slightly sweeter than you expected. As you clean her hand, her other hand has opened the wooden box on the table and is rummaging through it for something.
She pulls out a smooth, purple silicone dildo, about eight inches in length, with a handle at the end. For eight inches, it was thicker than it should be. She holds it in front of your mouth, and you abide, opening your mouth so that she can slide it in.
She doesn't force the whole thing into you, just the first couple of inches.
"Sorry, sweety. I'm just not sure you're wet enough yet, and I don't want this to hurt, so we don't want this going in dry."
You wrap your tongue around its tip, trying to coat as much of it in your saliva as you can.
Before long, she removes it from your mouth and moves it between your legs. Your whole body tenses as the tip presses against your lips. You squeak when the tip finally forces its way into you.
Kara's left arm tightens around you, holding you in place, as she starts to slide the dildo in and out. It's slow and rough at first, just a bit too thick to be comfortable. You can't stop yourself from grunting each time it stabs into you.
Soon, she speeds up, and your grunts become heavy, broken moans. She feels you slumping forwards and tightens her grip around your neck. You're not going anywhere.
You're on the edge when she pulls your hair to the side and runs her tongue up your neck. It sends a chill down your spine that's all too much for you as you're shaken by your second orgasm of the night.
But this time she doesn't slow down. Her hand keeps thrusting the dildo in and out, in and out, as she dots your neck with kisses. You try to beg her to slow down but you can't get the words out, instead just spilling a mess of moans and profanities.
"Oh god- oh fuck- oh- no- plea-ease-oh-oh-oh."
She only seems to be speeding up and it takes less than a minute before your shaken by your third orgasm. Your body convulses as she hammers in and out of you.
"You're so good for me", she whispers in your ear.
You try to respond.
"Pu... Plea... I- can't- uh- ooah!"
She keeps going, drilling hard until you hit your fourth orgasm.
This time, she immediately stops, as your body slumps against hers. Your vision is hazy, and you can see stars floating by in the distance, as you pant, desperately trying to get air back into your lungs. She slowly slides the dildo in and out a few more times before removing it completely and putting it on the table beside her.
You're completely drenched in sweat, and you can feel her tank top against your back, slowly soaking it up.
She doesn't say anything. She knows that, after that, you need to rest for a while before anything else can happen.
After ten minutes you pull yourself upright in her lap, turn, and kiss her. She leans into it and kisses you back.
When she breaks the kiss, she smirks at you.
"We're not done yet, you know."
You smile at her.
You have half a mind to call it here. Your body feels wasted and exhausted and you already know you're gonna be sore tomorrow morning. But Kara was really looking forward to tonight, and definitely had something intense planned. You didn't want to disappoint her.
"Ok. What's next?"
"Next, you get to make a choice. I've got something really big planned, but you may need your hands for it. Then again, it could be more fun to watch you struggle. So, you choose..."
She reached into the box and pulled out a silver ball, about the size of a golf ball, with a string attached. Along the string were four more balls, all the same size. Anal beads.
"I'll untie your hands, but only once all five of these are in you. Or, you can pass on this, and face whatever comes next with your hands behind your back."
You thought for a moment, but it was an easy decision.
"I want my hands free."
"Excellent. In that case, lay down across my legs."
You lay down on her lap, with your butt raised to one side and your head hanging over the other.
She runs her hand under you. You're still wet from earlier, so she runs a finger between your lips, picking up moisture. Then her finger trails up your ass. She dances around you for a moment before sliding a lubricated finger in. It's tight, and you feel a tension in your breath. She slides her finger in and out a few times before pushing the first of the beads against your ass.
After a moment of tension, it slides in with a pop. You already feel your breath getting heavier and more laboured after having something forced into you.
"Remember, you need all five if you want your hands free."
"I know", you pant.
The second one slides in easily, but the third one meets some interference. You already feel full when the third bead finally pushes its way into you.
You're breathing slowly and audibly now, and you can feel your face starting to turn red at the unexpected pressure in your ass. It was getting uncomfortable.
As she pushes the fourth bead against you, you hesitate.
"Wait- sorry, I just... need... Could you slow down a little?"
"Sure. Let me know when you're ready."
You count your breaths as they slow down. After eight breaths, you're ready.
She slowly pushes the fourth bead in. There's immediate tension as it forces its way into your ass, pushing the other beads aside. You feel completely full and grunt as the bead finally settles inside you.
"Oh- fuck", you groan.
"You ok?"
"Yeah, it's just... Way harder than I expected."
"We don't do anal enough. It gets easier with time. Let me know when you're ready for the last one."
You're not sure if you would ever be ready. You try to steady your breathing, but you feel shaky, and your face feels like it's burning.
You knew you weren't gonna feel comfortable any time soon, so after a minute, you gave the go ahead for the last bead.
You feel the beads shuffling inside you, trying to accommodate the fifth bead as it takes it's place. The moment it's in, you arch backwards. Your ass feels so tight and full, you're not sure you can contain it.
Kara strokes your hair and runs her hand along your back.
"Just focus on your breathing. It'll feel more comfortable with time."
As you try to bring yourself back down, she unties the ribbon holding your hands behind your back.
Once your hands are free, you try to sit up. But you feel a bit dizzy, and flushed. Kara holds you to stop you from falling over.
"Hey, are you ok? We can stop now if you want."
"... No. I want to see what this big surprise you've got planned is. Just... Can I have ten minutes to get comfortable?"
"Absolutely. Actually, I need to get the surprise prepared. I'll be back in ten, maybe fifteen."
She gets up and hurries out of the room. You try to settle back into the chair, but the tension in your butt keeps you from relaxing. As you shift your body, you can feel the beads pressing against you. Sometimes it hurts, sometimes it feels weird, and sometimes it feels strangely good. You try to settle into a comfortable position and wait for Kara to return.
By the time Kara returns, fifteen minutes later, the beads are no longer causing any discomfort, and you've gotten used to the full feeling they give you. But now you've got something else to worry about.
Kara was no longer wearing any pants. Instead, she was wearing a harness around her waist. Attached to that harness was the biggest strap-on you've ever seen. The black and yellow dildo was over a foot long, and thicker than your arm. She returned, and you let her resume her place on the leather chair.
"Comfortable?"
You nod nervously.
"Good. Now sit."
You sit on the chair in front of her, straddling her legs, the massive dildo between you. With it leaning against your belly, you got a better understanding of its size. It went up past your belly button, with the tip sitting just below the bottom of your ribcage. You stare at her, dumbfounded.
"You know that's not what I mean."
She put her hand around the tip of the dildo and said again:
"Sit."
"Kara, I- there's no way... I'm not sure that can even fit in me."
"You won't know unless you try. Come on, you've worked so hard tonight. It would be a shame not to see it through to the end."
After a moment, you pick yourself up and rest yourself hovering above the tip of the dildo.
Slowly, carefully, you try to lower yourself on to it, Kara guiding it to its destination. It presses hard against your lips, and you hear yourself whimper as it parts you and the first inch starts to enter you. You immediately feel a painful stretching sensation between your legs and try to pick yourself up.
But Kara puts her hands on your hips and holds you in place.
"Kara, I can't, it's too much."
"Please, sweetie. I know you can do this. Whatever happens, I'll take care of you. Please, for me. One more try."
You know this is going to hurt, but she seems so desperate to see you try.
"One more try", you repeat.
Her hands push lightly on your hips as you lower yourself back on to it. You feel the first inch push its way in and wince. It's so thick. Her hands apply a little more pressure on your hips as you spread your legs, trying to get a bit more purchase and...
"Ah- FUCK!"
Six inches of the dildo quickly ram into you, stretching you beyond anything you've felt before. It felt heavy inside you, like a stone, and an immense tension quickly spread throughout your lower body.
You immediately slumped over Kara's shoulder, gasping and panting desperately. The strap-on had completely knocked the wind out of you. Kara wraps her arms around you, holding you close to her, as you panic, trying to get your breath back.
She doesn't say anything. She knows you can't talk right now. She just waits, until she can hear you slowly and steadily breathing in and out.
"...are you ok?"
"... I think so..."
You lean back and put a hand on each of her shoulders, looking into her eyes.
"I... wanna keep going..."
"Ok. You set the pace. I won't rush you."
After another minute, you slowly pick yourself up off the dildo, sliding almost all of it out if you. Then, just as slowly, you go back down, and it pierces back into you. You wince again, and feel a couple of tears sprung to your eyes and it's thick volume floods into you. As it moves, you feel it pressing against the beads in your ass. You barely notice them now.
Up and down again, it hurts less this time. You gasp as it punches into you. Kara's hands on your hips match your rhythm, helping you up and down. Soon you're moving rhythmically, bouncing on the dildo as it stretches into you.
Each time you bear down on it, it goes further in. After a while, about ten inches are sliding into you. You can feel it hitting something deep within you, as though it were punching the back of your womb. Each time it hits you, it brings you closer to orgasm, until finally, it sends you over the edge.
Shaking and moaning, you cum around the giant dildo stuffed inside you. Your legs go numb and collapse under you, and all sixteen inches of it pierce into you. You let out a sharp sob and feel your body shake at the unnatural feeling. Your insides feel twisted and torn, but your body's still being rocked by your orgasm, waves of pleasure shaking through you.
Your body keeps twitching, and you can't tell if it's from pure unfettered pleasure or from pain willing you to burst into tears. But you know you want more.
You try to lift yourself up, but your legs don't obey you. They're too weak.
"Do you want to keep going?"
You can barely get a sentence out.
"-again-"
Kara carefully picks you up, slowly sliding the dildo out of you as you let out a long, unhinged moan. Then she lowers you again and you feel it pour into you again, filling you up and stretching you, and you let out a sharp cry.
You give no sign of resistance, so she continues, up and down again, as you hold onto her shoulders, trying to not lose control.
You want to beg for more but you can barely stay upright. You cling tightly to her shoulders as she rams into you, harder and faster.
Finally, you manage to get a word out, but you're too late.
"Faste- fu- Ohohohhhhhh!!!"
You desperately wrap your arms around her neck, sobbing and moaning and screaming as another orgasm burns through you, soaking the dildo beneath you. Your legs are numb and your brain feels like it's on fire.
But she doesn't slow down. She picks you back up and rams you back down onto the dildo. You feel your stomach stretching, warping. It feels like you're going to explode.
You started feeling nauseous and dizzy a long time ago, and now you're just holding on for dear life as she slams into you, each hit feeling like it could break you.
As you finally lose control of your body, you hear someone scream in the distance. Another orgasm hits you and your body shuts down. Your mind is flooded with pleasure, you lose all feeling in your body. You fall forwards, collapsing over Kara's shoulder, as you pass out.
-
The first thing you notice when you wake up is that you're lying in a wide, open bed with a light silk sheet over you. The second thing you notice is Kara sitting on the side of the bed, watching you as you come to. The third thing you notice is a sickening hollow feeling in your body, as though you hadn't eaten in days. The strap-on was gone, and the anal beads had been removed. Kara had changed into a fresh set of clothes.
"What happened?"
"You passed out. Again."
You fell back against the pillows and sighed. This wasn't the first time you'd passed out during sex, but it was definitely the most intense.
"Sorry. I... I should've used the safeword but..."
"It's ok. I understand. I don't think you had a chance to use the safeword after we really got into it. You sounded like a maniac."
She laughed to herself.
"I'm sorry if I asked too much of you. I knew it was really big, and that it might be a bit too much for you, but... I also didn't want to underestimate you. You've been trying so hard to satisfy me recently, and I wanted you to know that I had noticed. Maybe I rushed things a bit too fast."
"I- I understand."
You wince as you try to sit up. Your legs still feel somewhat numb. You take a moment to collect your memories of the previous night. You finally remember what happened.
“That… was a lot. But also… I really enjoyed it.”
Kara laughs to herself again, and you can see a tear in the corner of her eyes. She’s been worried about you.
“I’m glad you enjoyed it. I had a really good time too.”
There’s a glass of water next to your bed. You pick it up and down it in one go. You hadn’t realised how thirsty you were.
“Can we… do that again some time?”
She smiles down at you, but there’s a look of concern in her eye.
“Yeah, once you’ve rested for a while. In a couple of days, maybe. But we’re not using that strap-on again. I don’t want to see you like that again.”
“Agreed.”
“AND you need to remember to use the safeword. The moment it feels like it’s getting to be too much. I understand that you want to please me, but I don’t want to have to worry like this again.”
“Right, you’re right. I’m sorry. I’ll try to be more prepared next time.”
“It’s ok. You don’t need to apologise. Do you remember the safeword?”
“Midnight.”
“Excellent.”
She leaned down and kissed you on the check.
“Now rest for a while. I’m gonna get breakfast started.”
