A talented squirter! Next-generation AV star Mugi Koseki Koseki makes her AV debut at age 20! Even when she masturbates, she feels good and squirts (embarrassed). It's hard to keep it a secret from her parents... She's quite lewd even though she goes to a rich girl's university! She was a virgin until a year ago, but at university she's not only enthusiastic about studying but also about naughty things! She's a bit of a pervert who collects photos of sheets wet with masturbation squirts! Apparently she flooded a love hotel bed and got banned (lol). She's cute as she squirts despite being nervous and embarrassed during her first shoot! She's good at dancing and is good at being proactive in sex, swinging her hips herself! She's a promising Hope who will become even more erotic in the future!
