Catching my stepbro masturbating and asking him to fuck me

I caught my stepbro masturbating in the bathroom, and I got so horny that I started rubbing my pussy while watching him. He saw me, and I told him that we're not related since we're stepbrothers and mom and dad are not even home. I got on my knees and started sucking his big cock. We then moved on to the bed and had sex in different positions. When he told me he is about to cum, I asked him to ejaculate all over my face. For sure, he wasn't expecting to fuck me, but from now on, at least I know where I can go to have a good fuck when I need to.
