New beautician Miku is lectured by a veteran female instructor (Akaiko) on anal sensations and learns the pleasure of the anus... She quickly shows her talent, and even though it's her first time serving a customer, she licks the customer's anus with her drill tongue, and makes him cum with her amazing handjob technique while sticking her finger in his ass...! She gives him a beautiful ass job massage, licks each other's anus, and then has anal sex with her own ass, exclaiming, "Wow! I'm cumming from my ass!" as she cums over and over again in her first anal sex experience!
