HUNTB-265 - First Time is a 3P? My Slutty Stepsister Turned My Innocent GF into a Nympho

The part featuring Mao Hamasaki was great. As the step-sister, Mao Hamasaki greets her with a lesbian act and makes her climax with her fingers. After that, she coaches her while they perform a double blowjob on the step-brother. Finally, she coaches the step-brother while he penetrates her. Before penetration, she gets him erect with a blowjob, and during penetration, she guides him by hand. Furthermore, upon realizing she's not good at cowgirl position, she moves her aside and demonstrates it herself.
