Secret Pussy Collection ~Please look at Yuka Negishi's pussy~

About this work

A deep-dive investigation into the pussy, the origin of all humanity! We thoroughly examine delicate amateur pussy of Yuka Negishi using various instruments! First, we insert a speculum that makes a hard, cold clacking sound! While Yuka, apparently uneasy as she feels the cold metal inside her vagina for the first time, we got to look deep, deep inside her vagina! Since she seems tense, maybe the temperature inside her vagina is higher?! Does the temperature change before and after climax?!
