CREAMPIE from my sister's boyfriend

While my prudish sister's boyfriend was putting up the ceiling lights in the living room, I sat in my room wanking my horny wet cunt. He was actually watching me the whole time and stood in front of me with a hard-on in his trousers. As wet as my cunt was, he came just in time. I'm a dirty little brat and my boyfriend needed to release some pressure. I greedily sucked his hard cock and let him fuck my horny cunt until he squirted his bag cream into my cunt. As dirty as I am, I pushed my fingering into my cunt and sucked the cum off. Do I have to have a guilty conscience now?
