Your sister caught you stroking your cock while you watch her do her yoga workout. What the fuck, don't you have a girlfriend now, why do you need to do this? What? She dumped you? And the reason was that you cum too fast and have a pee fetish? Don't worry, your bratty sis can help! She can train your cock with JOI to make you last long enough....not for free of course, you will give her half your salary for this month. That's too expensive? Ok, what if she pees at the end of the cum count down? She has been wanting to pee so badly anyway! Are you ready to stroke it at her countdown and enjoy her teasing while showing you her body and cum when she pees?? ;)
