Fortune’s Daughter - Not a ton of sex, but I enjoyed the way the 2 MCers interacted/fought.
The Fountain of Youth - I enjoyed how magic backfired and the end result and how the main character handled it.
Four Tapes and a Fiancee - This definitely falls into the win some lose some category.
Frank & Jessy — Collar Play - Definitely worth a read
Free Ride - A very nice little college conversion story written from the controlee's point of view.
Free Ride Part 2 - An excellent sequel and conclusion to the first part.
Free Trial Offer - Pretty simple, but kinda fun
Free Universal Carnal Knowledge - Very good story, well written and fun(definitely long)  Plenty of good sex too.  I'd recommend the author but this is his only work.
Freedom to Fly - ALWAYS read the warning labels
Friendly Games - A fun little hypnosis story with 2 girls
Friendship vs. Hypnosis - I really liked this one, it could REALLY use a second part but is complete as it stands.
Fulfill Thyself - Not bad, definitely needs another part or three.
Fulfilled (Hypnotic Finale) - Fun in a "the author doesn't understand hypnosis at all" kind of way.
Full Disclothes Her - Once again, ALWAYS read every word of a contract.  Still, fun little story.
The Funniest Joke in the World — Bimbo Version - Good Wishes gone wild humor, quite funny.
Funny Money - Quite enjoyable, not the best magic money story but a good one.
A Funny Thing Happened on the Way to the Con - Magic dildo, unexpected consequences, a fun little story.
