There is typically some kind of erotic tickling or tickle talk leading up to sex.
I always try to please my wife first. When she has climaxed, her clitoris is very sensitive and ticklish. If I continue to stimulate her post climax, she’s like a spider monkey! She freaks out, but if she can muscle through, she’ll climax again.
My wife will squiggle her nails on my back when I’m getting ready to finish, and say something along the lines of “See how badly I could tickle someone if I wanted to.” Which makes me think of her cruelly tickling another woman, and Boom Goes The Dynamite.
Also, sometimes we do a position called X-E position. Basically I drape my right leg over her torso, and she extends her right leg up over my left shoulder. At this point I’m basically laying perpendicular to her pelvis. When I’m getting close to finishing, I will stoke her arches, or squiggle my nails on her soles, or suck her little toes if we are both particularly flexible that day.
Lastly there have been times when I’ve been on top, close to finishing, and just gently dug in my thumbs in the soft area between the ribs and armpits, back by the lats. And just pounded away while I was making her guffaw!
However, I try not to have too intense of tickle sessions before sex. I put her in my collapsible stocks once and went to town on her feet. No mercy. When I released her from the stocks to have sex, she was so frazzled she didn’t know how to react to any touch.
