I just got to this episode and agree that it's part of her dress. The way it was presented, and with what Mario says, it seems like he's talking about his cock. So, you're expecting that to be what is hanging there. I re-watched it, and I agree that it's part of her dress.it looks like it could just be the back of her dress which you catch a glimpse of through his legs. at the time i thought it was a massive cock.
