Treasured Pussy Selection: Yuka Negishi

In a clinical examination, Yuka Negishi is subjected to a thorough inspection of her pussy. A cold metal speculum is inserted, forcing her walls open to reveal the deep interior of her vagina. Despite her visible anxiety at the sensation of the metal, the examination continues to the furthest reaches of her canal.

The focus shifts to her internal temperature, which has risen due to her tension. The investigation seeks to determine if her body heat increases further as she reaches orgasm.
