Knees more ticklish when legs straight?

[Lostcause13]

So a couple weeks ago I was tickling my fiance and i tried getting her knees. When we skype she always cringes when i squeeze my own knee but i couldnt seem to get hers until this once, and I realized it only works when her legs are straight. Anyone else notice this or something like it? 'Lees are any of you oddly specific with spots like this?

That is interesting how her knees are only ticklish when they are straight. The backs of my knees are super ticklish whether they are straight or bent.

My girlfriend is only ticklish when her knees are bent. Interesting.

My knees are not ticklish on the front, but very ticklish on the backs when my legs are straight.

When my legs are bent, I just find it erogenously ticklish. Very nice.
