Fucked her again

So I haven't seen my sister in about a year. Ever since we were in your teens we fucked. Yes wrong but so hot or wrong that I came three times without stopping. She came into my room the other night after being out late. I only have a sheet on in the summer and was half asleep but wanted to see she'd react to me rolling over and the sheet came with me. At first nothing but she did grab me and before long she had my cock in her mouth. Slowly I'd meet her downward with my own thrust up. She was close to me so I just started running my hand under her skirt. I had a hand full of ass but could still slip a finger inside her pussy. So wet I just wanted my cock inside her. I know it's wrong but she was one the pill. Still the feeling as my cock goes deep inside her is a feeling you get only when doing something wrong. I came as we were spooning, my feet and legs stretched out and cuming inside as I pulled her hips to me. I kept fucking never losing my erection. Squeezing her tits " by the way their fake" and sticking my fingers in her mouth to suck on makes me sooo horny I came again. Thinking back when she was 18 I believe is when this started. She had gotten a really big tattoo and she wanted to show me and said lets go in your room. We went in and she took off her shirt which I never saw her in just a bra. I told her to tell her doctor nice job. She told me to feel them, ok and they felt really great. I gave them like the double squeeze with a lift. For a quick second I forgot it was my Sister and kind of worked her nipples over. I didn't realize she had her arms holding on to me kind of like a loose hug. That got my cock to start to grow. So I could see the tattoo, it ran from just below her armpit to her mid thigh. She pushed her pants down so I could see the enter thing but all I could focus on was that she took down both her pants and panties and I'm in front of my sister naked from her bra down. Why was I so turned by my sister? I could feel precum running down my leg. She said wait and took off her bra. For some reason to grabbed her tits again and played with them and she's just standing there asking me they feel good right. So much precum is running down my leg now it's just a constant flow. I told her to turn around so I could see her ass and she did no problem happy to do what I asked. I reached and grabbed her and my Cock. Felt so good I just wanted to take it out and jerkoff on her ass. What I forgot was my big mirror, and she was me grab my cock. She said I guess you approve. I told her I'm not sure of anything right now and dropped my shorts. She bent over and reached under to feel her pussy which matched for being wet. She bent way over and I figured her for about five seconds and came like never before in fact when I finished. I pulled one ass cheek over to see her asshole and came all down her crack. I laied her down and went down on her and she had a double orgasm and I jerked my third load on to the floor. I never realized she felt like that but I do remember waking up a few times and she'd be in my room . But if she was as Horny as I was then that would make sense. Since then we've fucked for years. Always giant loads. Hoping she comes in my room and wakes me by sucking on me. I really want to eat that pussy
