In this POV roleplay, I am your sister who you catch one early morning as I'm sneaking home after being out all night without permission. You threaten to tell our strict parents if I don't comply with your disgusting requests. Horrified, I flat-out refuse at first, but when I realize the position I'm in I reluctantly take out my tits and let you touch them. I see that your cock is getting hard in your pants and I call you a pervert. Against my protests you take your cock out and demand I suck it. Again I am disgusted but I realize I have no choice. I gag on your cock, cringing while talking about how disgusting it is that I'm sucking my own brother's cock. Just when I think it can't get any worse, you tell me you want to cum in my pussy. I beg you not to, telling you can blow your load anywhere else, just not there, but you will only be satisfied by cumming in your own sister's cunt. You slide inside me while I cry and talk about how much I hate it and what a pervert you are. Finally you blow your load inside me and leave me alone, curled up on my bed to suffer in the shame of having been fucked by own own pervert brother.
