Great pics! I like the fourth one the best, myself. She looks like she's REALLY ticklish, and had been tickled for awhile before the pic was taken. Her expression seems to be enjoyment on the edge of hysteria tinged with panic. She kinda looks a bit like Jessica Biel to me. Very sexy mouth, smile and I'm sure, laugh. Whatta lucky guy her boyfriend must be.
The girl in blue in the second post also looks like a great ticklee, and her friend sure seems to like tickling her.
I'd pay big money to see fullblown clips with both these couples.
Again, great stuff, thanks for posting!
