[IENF-437] Black Gal Sumata Ejaculation Challenge! If you are made to ejaculate within 20 minutes of nipple twisting and sumata, you will receive a prize of 1,000,000 yen!

Recruiting self-proclaimed gals recruited online to the studio to verify whether gals are really sexy. From casual talk to romance stories, it develops into adult erotic topics. If I make her climax with nipple twisting and sumata within 20 minutes, I'll say '1 million yen' and make her do sumata. Feeling anxious about the man who can't climax easily, she herself finds herself rubbing against her and feeling good, so she ends up inserting it into her.
