Sitting On My Brothers Face

Ok, ever since I was about 6 and my brother was 7 I have always loved sitting on his face. He's not as strong as me so it's very easy and I love the feeling of his face buried in my butt. It's pretty cool having a brother you can beat and humiliate so easily and it gets me off so much. I'm 15 now and he's 16 so we don't do it as much anymore, I still try to do it when we can, it's just I have a boyfriend now and he takes most of my facesits. Anyway we used to do it loads when I was about 13 and he was 14, I was blessed with a big butt and nice thick legs so it was very easy pin him down as I developed early and he was only starting, so he was still a bit of a wimp haha. Anyway our parents worked till 6 on weekdays and we both got home from school at 4, so I usually got a chance to do it every day, lucky me :L. I usually did it in my school uniform because I always wore a skirt (because of my butt) and that was the best thing to sit on his face with. So usually what would happen was is when we both got home from school, we would both go in the lounge and watch T.V. He would always watch me when I was around him because he was very aware of my fetishes. So when he started to doze off a bit in front of the T.V. I would grab his feet and pull him off the couch in to the center of the room. He would start off fighting, trying to wrestle me back, but he was a skinny boy and I'm quite stocky so I would easily get the upper hand and pin his arms down and sit on him. He would have a very worried look on his face as he knew what was going to happen (haha evil me :L). I would start off my turning around and lying on him in the 69 position with my head resting on his thigh and my vagina right on his nose and mouth as that is my second favourite position (I lifted up my skirt as well so it was only my panties between my genitals and his face). It was very cute as he tried to push up my legs so he could breath, but he couldn't as I was very thick down there lol. This position went on for about 20 minutes, as I would rub my vagina up and down his face and push it up and down on his nose. It made me so tingly but I had to contain my *******, although I would just let out a little 'Oooh' every now and then. After I came, I liked to torture him a bit so I pushed myself up and plumped my big butt on his face. I saw him when he got hard-ons after I 69ed him, but I didn't want him enjoying it that much so I used to torture him with my huge butt, by nearly suffocating him. I got up to take off my skirt and he tried to get away so I put my foot on his chest and pinned him down until I undid my skirt (I'm such an evil sis lololol :D). Then once I was just in my cotton panties I would place my butt back on his face in the reverse facesit position and let his face sink in to my big squishy cheeks hehe. He would scramble for air and he couldn't get it because my butt is so big and I had my knees on his arms. He put his hands on my butt cheeks and tried pushing them up, but he just didn't have the strength, it was so cute lol. He was smacking his hands on the floor and muffling 'Brittany please, I can't breath', so I eventually let him have a sip of air and lifted up my butt slightly so it was still touching his nose but he could breath through his mouth. I felt his hot breath on my vagina and I let out an 'mmmmm' and he said 'Brittany please get off, your going to kill me', I said 'Don't worry babe, I'll take care of you' and pressed my cheeks back down hard on his face. In a few seconds he was scrambling of air again and I said 'Awww do you want some air, well here's some air for you' and I farted straight on his face. He was letting out muffled screams down there which felt so good. It went on for about 30 minutes and then I thought he had enough so I got off of him and he was very dazed and drowsy as I'd sat on him for so long, evil me again hehe ;). And as he lay there I said 'You tell Mom and Dad and next time you'll suffocate down there', and I put my skirt back on and went up to my room to text my friends. I'm not sure what he did after that, maybe he went off to go and ********** or cry lol  xxx
