Kusuri-san, naturally endowed with large breasts, and her male subordinate go on a business trip together. That night, only one hotel room was booked... With no choice, the two end up sharing a room. The subordinate is extremely flustered at the prospect of spending the night in the same room as Kusuri-san, to which she asks, "Are you still a virgin…?" From there, overwhelmed by the heat of a virgin, the night began with deflowering sex... an insatiable libido that didn't stop even after dawn, unbelievably intense intercourse for someone who had just graduated from being a virgin... until almost checkout time, the big-breasted senior made the former virgin cum non-stop.
