Sex with stepsister

Since my stepbrother and I met, we always hate each other for some reason. I'm 16 and 15. Well, one night she and I ended up in my dark room one night, and we were fighting in the dark, and we stopped all of a sudden, and some how our faces met, and our lips were touched, and all of a sudden they were "doing out," and we did it for about 5 minutes, and I was hard as a rock, and I was just in my boxers, and she could totally feel what she had, so she started taking her stomach that was the first time she and I did something sexual together. So next weekend she was in my room again, she was in my room using my computer, but as soon as our parents went to bed, she got down, and she started to bother me, and every time she bothered me, we ended up fighting, so she started to fight around, I turned off my TV and lights, and she kept fighting, so the same thing happened as before, we started kissing, so she ended up with her care she gave me the head.

So about a month passes without sexual activity between us, and she's in my room again, and just like before, fighting, kissing, head, but this time I decided I was going to finger, so this time I feel my hand down to her clip, she then crosses her legs, and she makes them tight as it can be, so I'm trying to get through her legs, and I finally do it after 5 minutes I guess when the woman has sex for the first time, they can't walk right for a couple of minutes. That's what I think.

So now she and I are always in the same room. So on weekends when they went to bed we would do our thing, but most of the time they were having sex without a condom. But he doesn't prefer any condoms, which I think is a little insecure, but I didn't have any gums left. So one night she was shooting cats from the window of our bathroom, and she came in and started to bother me, so she sits on my lap, and I'm like what this girl is doing, so she won't let me get up, so I've managed to get up and, and she grabs me by my shirt, and she throws my face at her. We start kissing, then she forces me into her bag, so I take her shorts and panties aside and we start eating her, and the finger. So she says "put it in me," so she juice it, and follow her wishes, so she's sitting in the bathroom and I'm down, so I'm doing it, she gets up, and she puts me in the bathroom, and she starts riding, then I pick it up (they light), and she goes "different," then she says "fuck inside me," I said "don't suck."

After the bathroom thing happened, he told me I have to go for her twice, because once it's not enough for her. So now I'm shooting cats from her room window, and every night I went in there, we always had sex, no more head, no more eating her out, she just wanted sex. So she and I had sex over 20 different nights, every night I went twice, and a couple of times I went to the third, if I had the energy in me. And until this day we admit each other that we use ourselves for sex.
