We welcome the current and best squirting actress , Mao Hamasaki, as our instructor and give a practical lecture to five men who have tried to squirt but have yet to succeed. It feels good, but it's not quite right...I'm about to cum, but I can't squirt...She carefully teaches them how to use their middle finger to insert into the vagina, even as they struggle. Mao continues to give practical instruction with her finger still inside her vagina, as expected!
