HJMO-438 The fixed vibrator daruma fell over 18

We invited a group of close female college students to compete in a game where they have to play while being penetrated with a vibrator or dildo roter! Three teams of six players each took on the challenge. The winners get prize money, but the losers have to perform forced sex in front of their best friends! They must insert a fixed vibrator or dildo roter and head towards the goal. However, some can't endure the stimulation and experience their first ever squirting orgasm repeatedly, collapsing at the waist and reaching climax over and over again... Can the game continue? The vibrators won't stop until they reach the goal! Volume 18 of the popular series!
