My stepdad is a big man, and very strong. He got into bed with me today and took me up my arsehole. He told me that I was petite and had a nice arse that he was going to fuck, which he did. He used my anus to gratify his sexual needs, then jerked me off. He was rough but hot. He plans to have me suck his dick tonight when my mum is out. I want to.
