Kami-ki-san, who is quiet and unassuming at work. A colleague I started dating thanks to her persistent pushing. The guy is a virgin and always gets nervous around his first girlfriend. One day during a date, they get caught in a sudden downpour and end up taking shelter at her place… After taking off his wet jacket, he discovers that she has hidden massive breasts! He doesn't know where to look, but his crotch honestly reacts!
