SDJS-167 SOD Sex Science Lab: The female employee famous for her beautiful breasts was relentlessly tormented on the nipples and breasts. Did she end up climaxing from her nipples more than her clitoris or vagina?!

"If you torment it carefully, won't breasts feel better than a pussy?" Upon receiving user feedback, the SOD production team used female employees as test subjects to personally verify. From large to small breasts, various types were examined through palpation and toy torture, exploring breast sensitivity from multiple angles. The last two conducted the experiment simultaneously. Does doubled embarrassment also affect sensitivity...?
