GRMO-219 Human Observation: "We Have the Best Physical Compatibility" - A man reunites with his ex-girlfriend after an argument and rekindles their past sexual experiences through an emotionally charged sexual encounter.

A couple, seemingly former lovers, bump into each other at a convenience store and end up going home for drinks. As they drink and reminisce, memories of their wild student days flood back, and their groins begin to tingle. Once they realize they're both free, they become excited and begin making love voraciously. Despite knowing this person inside and out, today is the first time we've had sex without a condom. We're so excited that we both ejaculate inside each other.
