I got all dressed up tonight for my date.I put on a nice low cut dress to go out in, hoping it would get the point across that I really wanted to fuck.Well..that didn't happen so now I have to go home horny and frustrated to my big step-brother's house.You see, me and my step-brother have fucked before but after he came inside me last time, I told him we couldn't do it again.Like seriously, coming in your little step-sister's pussy??? Wtf was he thinking. I'm just horny enough tonight that I'm willing to break that rule. All I want is my big step-brother's dick deep inside me.Not so fast big step-brother, I put up a condom and put it on him with my mouth.He fucks me nice and rough in doggy and then when he cums, he tells me "Oops, the condom broke!" WTF!!!!!!! I know he did that on purpose! I knew this would happen. I can't even believe my big step-brother just came inside me! I try to push it out as good as I can but still, the damage is done and I'm not even on birth control!
