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.
