One day, I visited the hospital for a routine health check-up. The first nurse to examine me was Ruka, a gorgeous and big-breasted beauty who instantly caught my attention. However, the examination quickly took a strange turn—after measuring my height and weight, I was shocked to hear about a "penis length inspection." Next, I met Hikari, another stunning, big-titted nurse, who tested my vision and hearing, then proceeded to evaluate my sexual performance, leaving me completely bewildered.

What kind of results will I get? Find out in this intense, must-see title.
