For me one of the most memorable downblouse stories was my high school graduation. We were doing graduation practice where you are up and down out of your chair constantly. Well the girl I was sitting beside had a decent v neck top on. She had small perky boobs, probably a 32b. Well when she would sit down, her top and bra would both gap open and I had an unobstructed view right to her puffy nipples. I got this little show for 30+ minutes that day.
