My Christmas presents 18 [M] 19 [F]

This is a throwaway for obvious reasons
I (18)M had sex with my (22)F sister
My sister and I have always been close

So it was just before Christmas and we both never really got each other anything for Christmas but this year we decided that we would. But I had forgotten and so had she.

I was sitting in my room on my bed watching TV when she came into my room and she admitted that she had forgotten. Now as a joke I pretended to be annoyed but I quickly said that I was joking and admitted that I had forgotten too. She then said “can we watch a movie” and being the nice brother that I am said of course. Whilst we were watching the movie she put her head on my stomach which then gave me an erection. She noticed this and started mocking me for it to which I claimed that I couldn’t help it and she laughed.

What happened next is what surprised me. She unzipped my jeans and put her hand on my dick (over my boxers) I told her to stop and she did but she sat forward and kissed me, I immediately realized that I had sexual feelings for her, we made out for about 5 minutes then she put me on my knees and told me to pull her pants off so I did and I was met by the front of her thong which she took off and she then pushed my face into her pussy.

I immediately started licking it which made her moan, and fall back onto my bed and I kept licking until she squirted, she made me get up and she took of my jeans and boxers, I then took of my top and she took of her’s, so now I was completely naked and she was wearing only her bra which I took of quite quickly and she made me play with her tits, I started to squeeze them and move them around and rub them then I started to suck them, she then stopped me after about 10 minutes and she made me stand up as she got down on her knees and started to suck me off. It was the best thing of my life she went so slow yet so fast every pump was amazing. She then stopped that and stood up which made me upset but then she pushed me onto my bed and she then sat on top of me and my dick was close to her ass. She then lay down on me and started kissing me and moaning,she then sat up and grabbed my dick and put it in her vagina. She then road the fuck out of me, bouncing up and down, her fat cheeks clapping so loudly, her big tits bouncing up and down,she started moaning which was really hot, eventually I gave in and started moaning too, it wasn’t long maybe 2 minutes and I came inside her and she kept going whilst my cum ran out of her. She road me until I went soft then she kept playing with my dick until it was hard whilst I fingered her. Once my dick was hard again she started riding it again and we immediately started moaning we went again for about 5 minutes and she came but she kept going and moaning until I came again and my cum was running out, then we stopped. We then went for a shower(together) about an hour later were we fucked again but this time we did anal and it was amazing, her big ass was amazing, and then after dinner we fucked again and again we slept in the same bed and she fucked me whilst I slept and then the next day we fucked again and again and again and we have been in an intense sexual relationship for the last 3 weeks
