My step-brother and I were always close, but never this close. Our house is a complete mess because my parents chose to redecorate it and now we don't have enough space, we don't even have enough beds! It's not really a choice, between my step-brother's bed and the floor. I definitely will not inflict severe pain on my back laying on the floor, that's clear by now, I think...?!? I've felt really alone lately, since I broke up with my boyfriend... well, not only alone but also wildly horny! I have this habit: I like to cuddle a lot in bed, naked and sometimes the cuddling turns into sexy time! :)) I'm so used to share a bed with different boyfriends, or having one-night-stands, that it comes naturally to me: while I am in bed I rub against the guy's cock, or even touch his cock. I warned my step-brother about these habits of mine, but he laughed and didn't gave it much importance. Things happened quickly after that: I was dozing off and started to rub my butt against his cock, then woke up and realizing what I was doing! I was so ashamed that I ignored the situation to avoid weird explanations. I was horny, probably he was also and we cuddled and touched until his cock got real hard. He lifted my dress and put it right into my pussy, surprising me a bit. I pretended to wake up and to be outraged but the bare truth is I always wanted to have sex with my step-brother! It's a Taboo subject, nobody actually talks about it and for me it's really hot, it is a certain type of closure, very specific, a connection I've never felt with anybody else. He fucked my soft pussy with his big cock, making me scream and beg for more. I came, of course, not only because he was good at it, but because he is my step-brother and I finally got a chance to do this with him. I wanted to fuck a lot, he almost came once or twice, but I wanted to make sure I'll be living the experience 100%. Of course, I returned the favor by giving him a nice blowjob and DeepThoating that big cock, feeling it fill my entire throat. I wanted him to feel as loved and caressed as I've felt, offering him all my sexual attention and care. He certainly liked it, he came all over my lips and mouth, his cum being as tasty as an exotic fruit. I've never thought I'll do this with my own step-brother
