long-term Cheating turned into Voyeurism Fucking!? ( MxF )

I am looking for someone to play as Mary and Jess both Oliver's Lover and Cheating Lover, their personalities should differ quite some but with the girls being pen pals. Though I am mostly looking for Smut more than Story so if you are curious about how much of each then 65/35 Sex more than Story again I really want this to emphasis on the Cheating and Voyeurism Aspects. Anything is really up for debate though I do want there to be Dark Humor or mocking of Mary in a Sexual way as described below in Further Information. I do want My Writing Partner to be able to do Paragraph Length of Replies seeing as that is my standard response length to most of my RPs. ( There is also the Idea of Mary's Mother having Sex with Oliver behind her Daughter's Back~ ) 

Main Idea:
This RP can start in various ways so the opening is something we can talk over between us since I do want My Partner to have quite some freedom as well I do want Mary to be skeptical about Oliver fucking another woman but goes along with it and they find a young woman called Jess to do it with. However Oliver and Jess ends up doing it the day before the agreed appointment and decides to keep Cheating behind her back.

• Anything in here can be discussed and changed if needed be  
  • Oliver 35 Years Old is an adult who works from time to time doing small jobs and helping friends and family when Mary isn't busy that is with her Own Job.
  • Mary 32 Years Old is a working woman who does her Business at Home as well as in her Office selling Clothes all over the country, she is either home all the time or rarely.
  • Jess 22 Years Old is a Tomboy Fitness Chick who is a young aspiring sports athlete, training her body to be the perfect fit for both Sport and obviously Sex with strong Men.
