Here's mine...
1) A weekend camping trip. I do mean roughing it! A two man tent, cooking on an open fire, bathing in the lake or river, & having lotsa wild, lustful sex. 2) A weekend Rendezvous in Vegas. MUST include front row tickets to a Cirque du Soleil show! 3) A road trip on the back of a fully dressed motorcycle. NO crotch rockets! You must be able to concentrate on the road while I press my breasts against your back, & kiss your neck as my hands wander uncontrollably into your lap. Next.....1). I'm peacefully sleeping in the middle of the night and awaken by a mouth on my ****. I reach over and turn the light on and there is a gorgeous face with her lips wrapped around my ****. She stops briefly and gives me the 'shhh' signal and without saying a word continues. This turns into a completely erotic session of... Well you get the idea. Then she gives me a kiss on the lips and leaves without ever saying so much as a word.
2). I drive for Uber in my spare time.... I pick up a hot girl in a short sun dress with gorgeous, long, tan legs... She sits in front with me. After a few minutes she slowly lifts up the dress and she's not wearing any panties. She spreads her legs and grabs my hand... You get the idea... We finally reach her place and she invites me in.
3). Simple... Road head. That's right... I've had it in a non-moving vehicle but I want to have to concentrate on driving while exploding in a .... 
1. Find the hottie who got drunk and ditched me last summer...and make something happen this time.
2. Find at least three of the women who I turned down in my ultra-religious past and "make amends."
3. Have a proper threesome. For those of you who don't follow the GD board, I'm referring to the fact that I recently wandered into a threesome with two transsexuals. Not how I envisioned my first threesome, but oh well, it was still fun. But I want to experience a classic threesome with two "natural born" women. After that, maybe a "regular" woman and a TS at the same time. Oh, and ladies, I should also mention that I'm no hypocrite; in other words, if you are willing to indulge me in my threesome fantasies, I am perfectly willing to reciprocate and do a MFM with you. I won't pay for that one, though, because it would be YOUR fantasy.
Which per the OP haven't happened yet. Given my age, they probably never will happen. Especially the last one. But here goes...
1. Spending a week (at least) in an idyllic paradise setting with a beautiful, sexy, fun, adventurous, kind, cerebral woman. The closest I've come to realizing this fantasy was a wonderful weekend in a nice place with just such a woman. A weekend just isn't long enough!
2. A threesome involving a certain provider and my SO. And this provider rocks my SO's world like its never been rocked before. Then I make mad, passionate love to my SO while the provider gives verbal and other assists.
3. I'm not going to go into details, but it involves Charlize Theron. Or Scarlett Johansson. Whoever is free that day.
1. Job interview roleplay. I'm the interviewer. She says shed do anything to get the job. ...and, she does.
2. Shared wife (roleplay or real)....he wants to share, but also to watch via camera in the room while we romp.
3. Threesome....I'm still looking for the pair of perfectly matched ladies. I think I'm about ready to pull the trigger on this one.
1, I awaken from a deep sleep to my lover playfully sucking me hard, then continuing slowly, but with more intensity, until I finally cum in her mouth. She keeps me in her mouth for several minutes, letting me bask in her warm touch.
2. I'm transported back in time to my 16th year. The year I dated two cheerleaders.They both surrender to my charm & I get to fuck both of them (separately).
I don't want to relive what ACTUALLY happened back then. They were both pretty hot, but not ready to "go all the way". While making out, they each said pretty much the same thing, "we can kiss, and you can feel my boobs thru my top, but we're not going further."
3. Being seduced by Julie Newmar, aka Cat Woman, from the Bat Man TV series. For my money, she's the hottest Cat Woman, all time!
There's an ass shot of her (in costume) that's my fav. It's 1 min 46 secs into the video clip.

Think what Julie Newmar could have done with Spandex!
1) The quiet but smokin' hot high school girl (18 of course) who decides she likes the "dad" type and manages to let me know it.
2) As an Uber driver, I'd have to say "the pair of sexy Friday night club-dressed 20-somethings deciding they'd rather ride the bed than the car" has to rank right up there.
3) This woman two rows down from me at my new job who has the most amazing, simply the most amazing, ass in the explored universe. Any time, any place. I want to hold it firmly with my face buried between her thighs.
