I am a professional college educated male who most people would consider a 'normal' member of society.  I was in two long term relationships.  Both women were also professionals and very 'normal' on the outside.
Both were absolute sluts at the time I was with them.  The latter one, raised baptist, spent most of her time at college on her knees, and I don't mean praying.  She sent me so many stories in email of her escapades at a very high level college.  I still have them all. We used them for foreplay and fantasies.
We lived in an affluent suburb and we both made great money.  No kids, just dogs.  Ate well, took tons of vacations.  'Normal' upbringings and families.
We browsed porn and erotic stories together.  Sometimes we sent links of our favorites back and forth.  I still have many of those emails, showing her kinks.  We went a little nuts with it eventually.  We started some shared accounts and joined adult swinging date sites to meet single women and men to play with.  We had 'rules' of playing we stuck to. We never used our real names, only aliases or used first initial only, example "R" or "K" or our middle names.
Once on the sites, we performed live sex acts on camera and live video feeds.  I have pictures of her naked or in lingerie or covered in cum.  She used to send me naughty pictures of herself when I was on business trips or she was on vacation. I tired to enforce the 'no faces' in photos guideline but she wasn't always careful and sent me many with her full face included. I removed her face in most but I still have a few showing her full naked.  She is still a professional in sales with thousands of contacts that have zero idea of her escapades. 
We had sex in public and she often gave me head while driving.  Road Head we called it.  Before or after she always hiked her dress up or pulled down her pants in the passenger side, pulled out her tits and used her clit vibrator on herself with her feet on the dash. We did that same thing once at an airport in a vehicle.
We use to have phone and webcam sex with people from the sites often.  We met two different singles, one female and one male that we played with and video taped and took pictures of.  I still have photos of her in a strap-on and getting fucked by this woman in a strap-on.  I still have pictures and a video of her blowing a guy while blindfolded.
Years after we quit playing with others we still were crazy sexually.  And she had just started talking again about exploring our fantasy of her seducing and blowing the help at a hotel.  I guess her inner slut came back.  She ended up cheating with this fat ugly dude.  Maybe he lets her fuck guys actually.  To tell you how good she is in bed, he left his family for her. She moved to a small town in his state, I guess to marry him.
If you know how to do any deep web searches you can find the old screen name we used on some much 'darker' sites as well as some of our old photos if you know how to search the Internet archives correctly.  We posted a bunch on some adult based blogs
