Despite her naturally gifted H-cup breasts, influencer Reika Shigemori has only had one sexual experience due to her overly serious personality. In her first and final "one-off" appearance, she lifts the ban on creampies. Her fingers tremble in the unfamiliarity of filming, and she is astonished by the heat of adult semen being poured into her for the first time. With her gigantic breasts shaking, she instinctively swings her hips, graciously accepting the creampie. This is the complete record of a one-off affair that will be talked about forever, in which this earnest girl is baptized by pleasure and her lustful nature blossoms.
