Some time ago I posted a true tickling situation about my co-worker and her admitting to be ticklish without any prompt from my side. Today I got first hand data about my other collegue. She sits in the same room as the first one. Age 27, blonde, short hair, blue eyes, pretty face, has decent, although not very beautyful legs. However, the best are her really big, wonderful breasts. She often complains about them being too big, which doesnn't stops her from wearing tight blouses and low necklines. Often wears miniskirts with long cuts, too, so almost every time she shows a lot of her body. I always wondered if she was ticklish, tried to poke here ribs from time to time - no reaction... until today. We were sitting with some other people and sharing some jokes, everybody in a giggly, playful mood. She was sitting in an office armchair - the kind with wheels attached. I said I was going to lunch and asked if someone wanted to go with me. She said she would, but feels too lazy to move. Being, as I said, in a silly mood I grabbed the back of her armchair and tried to drag her out of the room. Laughing, she grabbed the doorframe. I pulled a bit, then realized the opportunity, reached with one hand and tickled her outstretched right side. Definitely a ticklish reaction - she wriggled and lost her grip on the dooorframe. She was laughing all the time from the situation so I couldn't say if she laughed from tickling as well, but body reaction was obvious enough for me. I repeated my action two or three times more, of course she was holding the frame with her other hand, so I couldn't roll her out of the room, but my goal just changed 😉 Only after some "quickies" she run into an idea to simply stand up from the chair. But I got my tickles and my answer - definitely ticklish. The other good part was that nobody, including her, cared. It simply passed as a part of a joke/silly mood.
