Her first Big Black Cock

Are you sure you’re going to be cool with this?…
because I know Marcus. When he gets here and sees me in this aetup, there’s no turning back. He’s going to fuck me with that big, Black huge-cock of his.
And he was never a “one-and-done kind of guy”. He’s going to bang me all night. As much as I’d like to do him again, I wouldn’t want to hurt our relationship. So… are you 100% sure you’re okay with this?
