Helping my stepsister take a picture for her boyfriend

I love whoring myself on snap chat and my stepbrother is one of my followers. While doing a photo shoot and he offered to help me. I could see him getting hard and to be honest I was getting a wet too. So when he reached for my panties and pulled it down a bit while I was posing doggy style I just let it happen. One thing led to another and I he ended up taking pictures of his cock pushing in my pussy. Then he threw away the phone and fucked me. It was wrong and that made it even hotter. I sucked on his cock and rode it thinking all the time that I'm fucking my stepbrother. He got really hardcore and then he fucked me in the ass. He shoot a load so hard that it covered my abs, tits, face and even got in my hair.
