Goddess Tinslee may be young, but she is ruthless. She is not a fan of permitting men to climax, and in fact will rarely allow such a privilege. But she will let you beg and grovel for permission to cum, after all you are nothing but a bank account to Goddess Tinslee.
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.
