Stretching for Anal [NSFW advice please]

Hi there anyways I'm pretty new to anal sex but I'm going to be getting fucked for the third time tonight in a few hours by this guy. I don't have the cash to spend on anything professional, so I was wondering what's a good household item I could use as a butt plug to loosen up for later tonight? Or if there isn't anything to use what else can I do to make tonight better? Thanks!
