I was just going to ask my brother to go for a walk together, but apparently I've chosen the wrong moment, I found him masturbating! I didn't want to see him like that, even though I had my curiosities, and tried to leave the room, when he asked me, kindly, to stay! He was having problems with his erection... His girlfriend dumped him last week and he was so hopeless, I decided to help him a bit, mostly out of compassion. I told him to relax, to breathe deeply and not to worry about anything anymore. I touched his naked body, his chest, nipples and I ran my fingers through his long hair. He liked that, became more relaxed and started to feel aroused. I felt naughty and thought it would be no harm if I tease him a bit with my big boobs! We both got aroused and heated so quickly, we didn't even realize what was going on until we woke up in the middle of it! I mean, with his hard cock in my hand, then in my mouth, then deep down my throat! We kept saying to each-other that is wrong, so completely, totally wrong, but this didn't stop us at all, we went all the way. He fucked my tiny pussy. He pounded it like there was no tomorrow and let me ride it in reversed cowgirl position. I bet he was getting harder and harder inside me because of my round, nice ass! After that I rewarded him with a TitJob, rubbing his big, hard cock with my tits, keeping it tight there and making him literally lose his mind! I played with his orgasm, taking it easy from time to time and working him up just until pre-cum wets his tip. I finally let him cum, and it was spectacular, he came a lot, between my Big Boobs, a real Titty Creampie!
