Once had a class in HS was a double whammy:
The teacher insisted on wearing (some variation of) a button-down silk blouse every day, lazily left open to the sternum. Enough so that you could catch a glimpse of some particularly delicate lace beneath there throughout the hour. She had titties just about the size of the model seen above. And they jiggled about ever so elegant and somehow blamelessly.
As if that weren’t enough to cause continual discomfort in my pants, chick sitting one chair ahead of me in the row to my right - religiously and EVERY damn day - wore the most tauntingly manufactured version of a skimpy angora sweater that’s ever been fucking developed (several variations of color while identical in style). Much like teacher, she’d leave those buttons left lazily open to the sternum. But unlike teach she would wear a demi-bra beneath them bewbies that would both propel her notably puffy nipples into the softest cloth known to man, while providing for extra and unstoppable jiggle at any moment she might think to move them somewhat hastily.
-I swear these bitches worked that out together. Likely had a chat with each others delicate parts on a daily basis afterwards.
