There are so many! You are only limited by your imagination and willingness to experiement with new ideas.
Personally, I like to play Captian Kirk as captured by a big breasted female klingon that is really jealous about me looking at green women!

... the one I can't play in real-life. The role I always play with providers is "guy who is able to pick up, sweep off her feet, and capture the imagination and interest of, this beautiful woman here with me."

Pity isn't it? I wonder if that means I'm just using providers as a crutch that prevents me from growing into what I want to be ...

Here's one I'm going to try one of these days.  I have a step-daughter.  She's 32 yrs old now and I've never touched her.  I'm no pervert but this is my fantasy.  She has recently split up with her husband and comes up to see me just to get away for awhile.  I only have one bedroom set up in my house as a bedroom.  All the rest I use for other purposes.  I tell her that she can have my room while she's here.  But she says "Dad, that's a huge king size bed.  There's room for both of us.  Don't worry, I won't bite!"  After a few drinks and chat, we're off to bed.  At this time my imagination is going wild but I would never hurt her by initiating something.  But as we slide under the covers, she asks me if she can put her head on my shoulder while she falls asleep.  I agree and she slips under my arm.  I can't believe it when I feel her reaching for my already hard penis.  When she feels it and realize I'm aroused, she pulls herself up to my face and begins to kiss me.  I can't resist.  We make passionalte love.  During this time, she confesses to me that she has always fantasized about making love to me.  "You're not my biological father after all", she says.  We have a wonderful, guilt free several days together and she returns home.  We plan to get together again soon.

Hey, it's just a fantasy.

I love role play and have had some fun experiences.  Being a provider has helped me realise some of my biggest fantasies.  I have done Dom/sub, Master/slave (my favorite), Daddy/daughter, teacher/student, doctor/patient, postman, repairman, oh so many to remember.

By the way, there is a sexy story in my Erotica section of my website for some Dom sub fantasies.

Some I would like to so, but have not:

Stripper/customer.  I have a big fantasy of being a dancer and have a customer proposition me and then do the date right in the club.  I know it happens but I have never done it.  I have never been a stripper....

Also the street hooker/john (my Guests are not johns...LOL  they are just very good friends coming to visit).  I have never done this because I am too scared to do anything with out some kind of screening...LOL.

I think th etwo above have alot to do with being in public.  I love public play.

I remember this teacher i had when i was in 7th grade she was blonde great body and wore miniskirts. she use to sit on her desk and cross those killer legs of hers in these shear nude stockings and bounces them. i never role played before because i always remember im role playing and i start to feel silly so stuff like this usually stays as a fantasy for me. so my fantasy is having to stay after class and teacher whos wearing a little minidress and heals and she has to be wearing shear nude stockings sits on her desk bouncing her legs slightly flashes me once and awhile she walks around me i can smell her perfume, she brushes against me and i can feel the softness of the fabric of her dress as it sweeps across my arm, she leans down to look at what im writing and her hair brushes against my cheek. its only us in the classroom and its after hours we turn off the lights and while standing i lift up her skirt rubbing the inside of her thighs and feeling her wetness through her silk panties we make love. ok anyone got a cigrette? damn
