We picked up some good friends, female college students, and had them play a naughty Daruma-san ga Koronda game! Three groups of six people take on the challenge, and if they win, they get a prize, but if they lose, they get a punishment game of forced big dick sex in front of their best friend! They aim for the goal while having fixed vibrators and dildo rotors inserted! However, they can't stand the stimulation and have their first splash orgasms in their lives, and many girls climax multiple times in a weak-kneed state... Is it impossible to continue the game? The vibrator won't stop until they reach the goal! The 18th installment of the popular series!
