I Had An Embarrassing Moment

i have 10DD boobs (or maybe bigger now, i need to buy new bras) they bounce a lot and i mean a lot. and i was wearing a tight button up top with a not so supportive sports bra underneath, so as you can guess my boobs were bouncing and jiggling all over the place, which meant all of the guy were staring at my huge bouncing boobs >.< so i had to turn to get to my locker which was right next to a guy, my shirt stretched over my boobs and the top three buttons flew off! >.<
but thats not the worst.. the bra was a couple sizes to small and it ripped in two right in front of his face. i quickly took out my extra top from the locker and ran to the toilets to get changed and this time i was going to be careful about it. but i had forgotten to pack another bra so i was going braless the rest of the day!! which was a little scary seeing as my boobs were pressing hard on the shirt which meant that my nipples were poking through the shirt and theyd brush against the fabric with every movement making them stiffen up. now that was embarrassing.. bouncing and showing nipples for the rest of the day... >.< >.<
