What we do when our parents are not home might be considered by other people Taboo, but for us is just so much fun! We like to do pleasant things to each other and we consider that this behavior is not harming anybody and it is our private business, as brother and sister! What happens in the bedroom stays in the bedroom!… I was laying on the sofa and reading a very interesting book when I discovered that the story is making me really fucking horny. So I lifted my schoolgirl skirt and began touching my pussy while continuing to read. I was aware that my brother was in the same room and that he will be a little surprised, but it’s not like we haven’t had this kind of fun before… He’s such a Mommy’s Boy, he was lecturing me on how Mom is gonna return and catch us and we will get into a Big Trouble. I laughed a lot, he’s so immature and naive, he’s still afraid of what mom will say if she catches us. Well, she will probably be so shocked that she will never speak about this, she would be overwhelmed by shame! We have no shame, on the other hand, we are young and we like to have new and exciting experiences. After I made fun of his fears I convinced him to get next to me and my masturbation turned into mutual masturbation, both excited by the danger of the “Big Trouble”, a sensation as thin as the air for me, but for him a real reason to be cautious! Apparently my hands are magical, while I was rubbing his hard cock he calmed down and wanted me to suck it! When I do a blowjob, no matter what a naughty little whore I was like ten minutes ago, I turn into a submissive slut and suck, lick and DeepThroat that cock until my saliva drains on my chin. We know each other’s preferences, exactly because we are brother and sister, and I know he likes me to DeepThroat it a lot, to cough and gag on it, gagging makes him even hornier! But let’s not forget about me and my precious porcelain pussy! I’m kidding, if the amount of cock I sucked and fucked would be measurable we would speak about kilometers! I wanted him, of course, to fuck me while I read that interesting book, to have two sources of excitement: his big cock and the entertaining read! He fucked me from behind while I was laying on my belly and reading, I had and orgasm so quickly that I didn’t realize what happened to me! After that he fucked me a lot missionary style grabbing my Big Boobs Bouncing to the rhythm of the fuck! I hardly achieved another orgasm because he acts like a fucking sissy! When he feels my pussy tightening and my pre-orgasmic moaning he cant hold it in anymore, and I don’t want him to cum inside me, it’s dangerous and I don’t want to take that risk! Well, I was kind of asking for it really, but my own brother cumming inside me, I guess is a little too Taboo even for myself! After a good long fuck, I felt that he just can’t abstain from cumming anymore and I told him to put it out in order for me to make him cum on my big tits. He really likes my big breasts! He likes them even more now with his cum splattered on them!
