Got a question for all who have partaken on an OTK experience - I've dabbled a little and am seeking to explore, but had 2 OTK experiences - very different, and was wondering what most would consider the "norm."
Experience 1 - naked, laying over her knees, but stomach on the legs, my cock was not touching any part of Mistress - just a plain spanking experience, not very sensual.
Experience 2 - also naked, but she position me so my cock was between her legs, she squeezed and seemed to hold me tight as she spanked me - very erotic and enjoyable, I'd opt for OTK finish almost every time if this was the style.

What style is most prevelant or do most expect to do?

Depends on your chemistry & devotion!

Experience #2 is more common in the lifestyle world.  Experience #1 is what you'd be more likely to encounter in a professional domination situation where some sexual stimulation is provided (but not all dominatrixes do that!).

Spanking is a wonderful warm-up for additional BDSM play, and many women can be rocked to orgasm from spanking.  It's a little bit more difficult to do with men, but we have a spot that stimulates the prostate if spanked.  It's entirely possible that you had a bad spanking partner . . .  I've run into some play partners who are wonderful at it, and others who are just into giving pain and/or simply don't know what they are doing (i.e., striking the same spot repeatedly, not giving a proper build-up, etc.).

Sometimes, it's more comfortable to be over just one knee, and the spanker can lower the other leg, so that the position itself doesn't compress the spankee in an uncomfortable way.  If you have a spanking bench (horse) to play on, that's even better.

It really depends on the lady and her personal boundaries and the energy between you two. I have done both types as well as other OTK techniques and it does depend on how well the client and I are connecting and what type of scenarion he seeks.

I like across the lap, with the bottom's cock trapped between my legs, but I think my favorite way is over one knee, with my other leg locking the bottom's legs down. I find it be a tad more intimate, with more body to body contact, and it allows for some squirmage against my thigh
