This work features adult cosplay in a uniform. She's a trainee from a certain idol group. Although she's still a trainee and has a bit of a naive air, she has beautiful D-cup breasts, thinly growing pubic hair, and is quite a high-quality girl. This is a video of her losing her virginity to her boyfriend, who she just started dating, in secret after a date in Tokyo, squeezed in between her busy daily lessons. The moment she becomes an adult as she slowly opens up her untouched pussy is always sacred and beautiful. Although she wasn't used to it at first, her moans gradually grew louder with excitement and pleasure, and in the end, she even has creampie... Please enjoy this virginity loss self-shot that would be devastating if her fans found out. All performers in this work are adults over the age of 19.
