Casual sex RP

This was an RP idea I pitched to someone but they weren't able to write it with me at this time. 
So I decided I would make a bulletin post for it to see if anyone's interested:

I'm looking for male characters for an RP in which our characters have sex so frequently that people who know them aren't phased by it much when coming over. The scenario I seek in particular is that my main character and your (main?) character are having sex at my character's apartment, and her friend (or friends) comes by to visit unexpectedly. This has happened before, so it's not uncommon, and the two don't stop or get embarrassed by being caught in the act, and the friend doesn't care much either. They all converse while the couple finishes up (or keeps going longer than expected), Go do other things, and perhaps the couple fucks in other locations too. 

It's relatively simple and not expanded on, so if anyone interested would like to expand on this with me, let me know. 

As for characters I seek, there's really nothing major I want. If you don't have a character and struggle to make one, the girl I'm going to use for the sex has a pre-made boyfriend character who is under developed for the sake of being able to be used if wanted, but I do encourage the use of your own characters if you have some you want to use. 

my preference sheet: 

The characters I would be using for this RP: 

Main character - 

Friend 1 - 

If I have any other girls I want to include that come over unexpectedly, I'll send their references individually. The girls who show up unexpectedly I do not want partaking in the sex, but I am willing to discuss if you prefer to have your character fuck one of them instead of Ella.
