My brother's clearly a prick, but I'm in a situation where I don't really get to chose, so he wins this time. I needed money desperately, as soon as possible, for a private matter. I know that I always ask him for money and forget to pay back, but we're brother and sister, family, these things don't count... do they? I went straight to his room and decided to not leave the room until I get my money. This time I wasn't asking for crumbles, but for 200 dollars! It was quite a bad, embarrassing moment, he was masturbating and had a raging boner. I pretended not to care and asked him, repeatedly, to give me money, trying to convince him, this one more time. He said something that made me think: he's give me the money but I literally have to fuck him for it! I thought: he's attracted by me (even if I'm his sis?... that's good for me, I can exploit that) I wanted to escape easily, giving him a hand-job, a quickie, all the men are happy after they cum, then he'll give me the money! But my brother is a stubborn horny man, though, after a good rubbing he asked for more and I bargained a few licks and surprises, and by surprises I meant DeepThroat. He was nicely impressed with my sucking skills, still wanted more! I sucked it a bit more, getting myself aroused, with my mouth wrapped around his big cock and showed him my sweet pussy, inviting him to pound it. He fucked me doggy-style and it was so intense I screamed! He made me cum, and it was my turn to squeeze cum out of his cock, to finally get my money. I edged him until cumming, he kept repeating he wants to last longer but I triggered the orgasm tickling his tip with my tongue. The cum-shot was spectacular! (and I got my money, thanks God!)
