I've known for a long time that my step-brother is a little perverted wanker. He was with me over the weekend. When I came home after a hot cum party, my step-brother saw me standing in the hallway covered in cum. It was obvious he was getting horny. So I showed him my stretched and pre-fucked asshole. This made his cock almost burst, and he shoved it deep into my mucky hole. I had no idea my step-brother had such a thick, hard cock. The other guy's cum from the cum party and my ass juice served as the best lubricant. I already knew that no cock could last long. So my step-brother's thick cock shot a mega cum bomb deep inside my filthy asshole.
