I had sex with my sister

One day I was really horny and I was in my room masturbating and watching porn, and the porn I was watching was about a brother and a sister so I called my sister into my room and she walked in wearing nothing but a T shirt and a thong. I was already really turned on and got an erection and then I asked her if she could give me a back massage since my back really hurt from football practice and she just said “sure okay” and then I asked her if she could sit on my back while she did it and she agreed. While she was massaging me, I could feel her butt cheeks up against my back as she was wearing a thong. Then I turned around and asked her if I could massage her too and she said yes then she took off her T-shirt revealing her perky breasts (she wasn’t wearing a bra) then she laid down and I began massaging her and I made sure to rub my hand up against the sides of her boobs as I was moving my hands up and down her back. Suddenly she put her hand on my humongous dick and I blushed. We were on a bed so I pushed her down and started kissing her as she rubbed my six pack that I formed from being on the football team. Soon I put my hand on her clit and started rubbing it super fast. As she moaned I went harder until she said, "don't stop!" repeatedly. Soon she had an orgasm. Then she pulled down my shorts and my big hard dick popped up. I pointed at my dick and said "suck" and she did. she started sucking harder and bobbing her head back and forth. I started groaning and then I cummed in her mouth and she swallowed every bit of it. Then she said “fuck me” so I pushed her back and slowly inserted my dick into her pussy. I started going faster and faster. We started groaning very very loudly. Then I cummed inside her and we just layed there for an hour and cuddled.
