I got a good tickle on my co worker who ive worked with for years today , was just me and her in the office and were pretty friendly with one another and i said feck it and got her good on her sides / front of belly , it suprised me how ticklish she actually was and she nearly ended up on the ground laughing so hard it was amazing she has one of the nicest giggles/laughs ive ever heard which made the situation 10 times better , got her for a good 10 seconds nothing crazy but still great experience
