Sororities can be funny and weird at the very same time. I got a dare I wouldn't believe I'll be able to accomplish, but the more I thought of it the more found it womanly and courageous, a way to break established and old social norms and have a lot of fun! The dare was to give a blowjob to my brother and I couldn't believe my ears when I heard it, but decided to do it anyway. It was an easy scene to set, as my brother naps naked almost all the time and I'm as sneaky and silent as a cat. To have proof to show the girls I really did it I was told to take some pics, you know, a selfie or two to prove I actually did it. I reflected for a long time on how I'm gonna convince him to let me suck his dick. He will wake up, he will be surprised, outraged, maybe even mad. How do I deal with his temper? I know he has a girlfriend, he's talking all the time about her and would be a shame if someone... sends the selfies right to his beloved girlfriend, wouldn't it be? That turned out to be the best method to blackmail him, after I sucked his cock for a while when he was still napping and he got hard, I took my selfies and then felt free to blackmail him without pity when he woke up and got pissed off. He is clever, he just feels that when I'm up to something, in this case to suck his cock and make him cum, he know he can't handle me, I just do what I want every goddamn time! So while he was whining like a little pussy about his need of therapy after this I was doing my part almost artistically, gently sucking and quickly DeepThroating all that big cock. What kind of man doesn't know to appreciate a blowjob, even if it's from his own sister? I'm telling you, he's a pussy who should have remained a virgin, he is too stuck up on old morals and the interdiction of taboo relations imposed by a society which is no longer here. He relaxed though and I'm 100% sure he enjoyed it but was to proud to admit it. First, he got an erection, secondly we can all hear his moaning while I lick or suck his cock not to mention the enthusiasm that follows every DeepThroat session. I think we got a little hypocrite here! I wanted him to reach climax so I sped up my rhythm and teased him with my huge boobs. I actually rubbed his cock between my boobs until he came, that hot cum squeezing in the air and on my tits confirmed to me I did an excellent job and he had an orgasm. Dare accomplished
