I tried bullying my little step-brother and now I am his toy

I am a tall, pretty (25F) Chinese girl, long legs and long hair.

My little step-brother came to visit my home yesterday. He is much younger than me (18M). He’s thin, half white half Chinese. We are only in touch with each-other sporadically but have a good relationship. We spent a lot of time as children growing up and he’s always been kind to me. He’s very funny and smart for his age.

When we were growing up, I always used to bully him. I have always been much taller, so he’s always been like a younger brother to me. Someone I play with, push around and bully as much as I like, but in a friendly way. After all, we are family.

He came to visit me two weeks ago. As soon as he and his family arrived, he and I went to my room to talk. He was wearing a t-shirt and jeans. I had white shorts on and a white top. We sat on the bed and mainly chatted about his studies, how school is going for him, my uni, the exams, etc. We vented all of our frustration with having so much to study and so little time. In addition, his family exert a great deal of pressure on him and are never happy with the outcome. This makes him feel stressed, I can understand that.

I ask him “What do you do to release the stress?” and he tells me about the video-games he plays, Valorant, Fortnite, etc. I tell him about my Yoga lessons and my habit of writing a diary. He notices the massive stack of pillows on my bed. Pillows that are oddly-shaped, pillows of all kinds. I decide that it’s now time to bully my step-brother and I propose we have a pillow fight.

We established the rules: if I win, he must put in order everything in my room, which is a complete mess, and hang all of my clothes that are piled up on the chair (I recently went out with my friends and had a hard time figuring out what to wear). If he wins, I will let him tickle me, which he always liked to do when he was younger.

Confident that I would win, as always, I start hitting him with pillows. Picking up the smallest ones and throwing them at him, aiming for his face. He starts being defensive and covers his face. God, I love spending time with my younger step-brother! He’s so easy to bully. Anyways, the fight continues, he sometimes fights back but it’s mostly me throwing pillows at him and pushing him around.

We are now left with the biggest pillows. Whoever falls from the bed first, loses. I start hitting his head with a giant pillow and he ducks, puts his face down protecting himself with his arms. I chase him around the bed and keep attacking, trying to push him out of bed. I lose the pillow, so I pick another one and keep hitting my poor step-brother until he surrenders. Finally….it’s over, I won! And as I turn around to fix my hair, he kicks me and I end up on the floor! I couldn’t believe it. He’s certainly become more sneaky.

I lost the pillow fight but I didn’t think much of it. He goes “Now you have to let me tickle you”. I say to him “Ok, how do you wanna tickle me?”. Before I could turn around and look at him, he’d already pushed me again and made me fall back. He then jumps on me, skilfully securing my wrists beneath his knees. He’s now on top of me, his knees preventing me from moving away, stuck. He leans towards me, comes close to my face and tickles my neck. I am not expecting this so I immediately start giggling and laughing non-stop, enjoying the moment. He continues, consistently, showing a little evil side to him that I didn’t know about.

After a minute or two, he stops and gets off of me. I can finally pull myself back up. We are now both sitting on the bed and for the second time, I try to put my hair in order. While I am busy at that, he comes from behind and locks my arms behind my back, and uses his other hand to tickle my neck again. I am no longer having this much fun. Then his hand keeps moving, runs down my belly and waist. I try to free myself but I can’t. He’s now much stronger and more dominant that I remember. He keeps tickling me and I start feeling very hot. Then, he does something that blew my mind. I did not see that coming.

He pulls my top up slightly, and starts running his fingers around my small breasts, barely touching. I stop giggling and become instantly serious.

“Stop! What are you doing?”

“Step-sister, it’s always been you bullying me. Now that I do it to you, you can’t handle it?”

I was surprised, not by what he said, but the fact that he said it and how he said it. His voice, his confidence. He has definitely matured in the last few months and is no longer the kid I used to bully. He is now bullying me! I try again to free myself but to no avail…he’s also become a lot stronger physically. After all, he’s growing into a man, and I am a woman. He holds me stronger and stronger with his arm. I am immobilised and cannot get away from him. I am now upset and irritated. My ego is hurting.

With the other hand he keeps going, he moves his hand slowly, in circular motion, coming closer and closer to my nipple. I try to move but I can’t. I suddenly feel weak. As if someone had taken away from me the ability to defend myself. He slowly teases me and finally touches my nipple and squeezes it. Then he uses two fingers to pull it slightly, he plays with it. I feel that we’ve crossed a boundary that we should have never crossed. However, strangely, I feel good. Technically we are not doing anything wrong. I guess, my step-brother must be very horny due to his age, or maybe he’s just curious of how the body of a woman looks like.

I made the terrible mistake of letting him tickle my breast, and now he is massaging it, and I think we are both liking it. Most men are not attracted to my breasts because they are small, so I don’t ever receive attention there. He’s really taking his time. Caressing it, Gently squeezing and releasing. Going from one breast to the other, and back again. He’s literally playing with my breasts. My breathing quickens. His hand runs up my chest, goes around my neck, then it goes back down slowly towards my belly. He tickles my belly for a bit, using his fingers, again, barely touching. He stops at my bellybutton, put his finger in it, presses a couple of times, then his hand goes down until it encounters my shorts. I instantly get wet.

I say “Enough”. I really thought that he should stop. But it’s as if I hadn't said anything.

“Don’t you like this, step-sister?”

It was obvious that my body was appreciating his touch. I felt so silly. I ended up just saying nothing, doing nothing and letting my little brother play with me.

“What are you doing? I am your older sister!”

I know what’s about to happen and I close my eyes as he puts his thin cold hand inside my shorts and starts massaging my pussy through the panties. I shiver as his fingers run down my wet panties, my heart is racing and I open my mouth fully gasping for more air. His one arm is still holding my arms behind my back, and the other is mercilessly working me up down there, getting more and more confident. He sticks his hand deeper and deeper between my legs, forcing me to spread them further. His whole hand is now between my legs, comfortably massaging my wet panties. I am stuck. I am on the bed, kneeling. My legs spread on either side. I now realise that the roles had flipped. This time, my little step-brother has caught me completely off-guard. I lost myself completely. He is now in charge and I am in his control.

As he massages my wet panties, the tension is overwhelming. I tilt my head backward, and it now rests on his shoulder. Our eyes meet, and for the first time, I can’t recognise my little step-brother. He’s confident, calm, dominant. I am scared and . He puts one hand on my forehead and pulls my head further back until I face the ceiling. He then takes his other hand out of my shorts, only to re-insert it a second later. This time…he sinks his fingers deeper to go inside my panties. As soon as his hand goes in, I come. I am very sensitive to touch and his fingers are now on my pussy. Touching my pussy. He stops for a second, as I twitch uncontrollably. He giggles and whispers in my hear: “You seem to be having a good time, sister”

He knows everything. My body is doing all the talking. I decide to completely submit to him and let him use my body as he wishes. I lift my knees up and he takes off my shorts. I spread my legs out completely.

“I am yours now, do as you please”

“But, please, be gentle, I am still your older sister”

He doesn’t say anything and continues working my pussy, taking full control. He pushes in softly with his two fingers. His touch is very light. I am in Heaven. My panties are soaking wet. He keeps going at me, I come again. I realise that he’s probably done it a hundred times. I guess he must do this to the girls in his school.

He’s no longer the little step-brother I used to bully. I am older and much taller than him, but right now I want to submit my body to him entirely. My head is resting on his shoulder, my arms are locked, and he’s dominating me sexually as if I was his little teenager girlfriend. As the time goes on, his touch slowly becomes more pronounced. He’s now pushing with his finger in between my pussy lips, looking for the entrance. I am scared. He’s subtly bending his finger, creating a gentle curve. And when he finds what he’s looking for, he pauses.

I am dying. My body shivers. My belly goes up and down due to my breathing. I am totally wet. His fingers are also now completely wet. I know what he’s thinking, he knows that I know what he’s thinking. I close my eyes once again. He starts massaging again, this time inside mi lips, using only one finger.

After one endless minute of agony and ecstasy, he finally penetrates me. Bullying my little step-brother is now a distant memory. I am now his little slut, submitted to his authority. He enters me slowly, gently, with his index finger. He pushes it inside, stretching my tight lips. He goes deep but not too deep. It’s not painful. His finger is still cold. My lips tightly wrapped around it. It feels good. He then pulls the finger out gently, which is sticky from all my juice. He puts his finger in my mouth, which I promptly open for him. I stick my tongue out and suck his on finger like a little girl. I now obey his every command. He pulls it out of my mouth, and penetrates my pussy again. He goes in and out, slowly at first, then faster. He’s definitely experienced and knows how to finger a girl. My breathing quickens even more and I realise that I am now moaning like a slut. I pull my legs up and spread them further to help him finger me deeper, and he does, sticking his finger deep and fingering my pussy like he owns it. He keeps fingering me with energy, stretching my tight lips, for another ten seconds, when I suddenly have the craziest orgasm. I scream. I have lost my mind.

“Quiet, step-sister!”

“If they hear us, I might no longer be able to play with you”

Suddenly someone knocks at the door. I think I must have been too loud. It’s his mother!

“Is everything OK?”

“What’s happening there?”

“Dinner is almost ready”.

He was quick to respond “Thanks, mother! We’ll be there in no time”. He then pulls his hand out of my panties, lets go of me, jumps out of bed and leaves the room. Before closing the door behind him, he looks at me and smiles. I don’t recognise my step-brother anymore…or even myself..
