FTHT-335 This is a bit sudden, but... would you mind letting me check the sensitivity of your nipples? Vol. 2

"Excuse me for the sudden request, but... would you mind letting me check the sensitivity of your nipples?" These innocent girls, without showing any displeasure (just kidding lol), readily agreed to this outrageous request. I got to examine the sensitivity of their nipples, examining the diverse boobs from small to enormous. Some were ticklish, while others were so sensitive I wondered where they'd been developed! The checks went incredibly smoothly lol. Which nipple do you prefer...?
