SDJS-223-Z - Detailed research report on a nude male subject by multiple clothed female employees. Serious penile encirclement experiment. SOD Sex Science Lab REPORT 18. Unable to take eyes off expanding nipples and pulsating penis while bewildered by sensitive reactions. 16 individuals.

This research aims to expand the sexual knowledge of female employees to generate new ideas for projects, products, and businesses, focusing on the correlation between a male's nipples and penis. How does stimulating the nipples affect the degree of penile erection, semen volume, and male response? We present a report from female employees who, while embarrassed, seriously touch, lick, and explore the nipples and penis. ※ This work is a partially edited version of SDJS-223 previously released.
