She's usually a music teacher! Her piano skills and penis handling are geniuses! Amateur wife with godly hands, "Riena Hatsumi", makes her exclusive AV debut with Madonna! In her debut sex scene, the actor ejaculates with a handjob before penetration! We didn't even realize until we started filming that she's a "handjob genius wife (unconsciously)"! She gently wraps around your balls from the base to the tip of your penis! Sometimes vigorously, sometimes gently, she kneads and twists with her 10 fingers! She shows off the one and only handjob technique she's unconsciously acquired over her 33 years of life for the first time in AV!
