Girls like Goddess Jessica love to torment men like you. They love to flaunt their complete control over your every orgasm, it definitely makes them power hungry. In this case it just makes her want to edge and torment you all the more no matter how much you beg to cum.
Your cock sure is tiny, how can you possibly expect to satisfy a girl like Madame Rose? The truth is you can't, which is why she ridicules you and your tiny cock as you stroke and hope to cum. She does find demeaning you to be cute though, if that's any consolation to being a loser.
