The other day I was in the shower washing my hair when the wife came in. I was rinsing my hair out so my hands were on my head when I felt her come up behind me and her fingers poking around my armpits! I get really stubborn when hit with suprise tickles, so I bit my lip amd pretended it wasn't doing anything and continued holding my arms up. I could feel *her* determination getting stronger as she went from poking around to skitter in her nails up and down my pits, sides and stomach, until I had to let out a "Rrrrrrrrrrr!" Finally she resorted to concentrating a firm spidering on the middle of my pits causing an inevitable burst of laughter and giggles and eventually I had to drop my arms. I turned around and had to look at that smirk that appears when she's won an impromptu tickling contest. Lol.
