Juice collector (Pixiv Fanbox)

What’s better than automated cum-collection machines? Of course: Cum-collection machines that force the trainees to work themselves~ This little setup here is especially cruel. The trainee is tied up and suspended from a rope connected to the ceiling. A super soft, heated, silicone collection device, coated in an extremely strong aphrodisiac that not only causes them to stay erect and horny but also increases their sensitivity greatly, is placed on their genitals with a tube leading to a collection tank. Additionally, lots of electric pads are placed all over the trainee, with some at, especially painful places. The trainee’s goal is to fill the collection tank as quickly as possible, taking a break triggers the electric pads, causing the trainee to get a playfully painful shock. The more breaks a trainee takes, the stronger the shock-intensity gets. This situation gives the trainees a choice between pain and pleasure~ Should they keep thrusting and stimulating themselves to the brink of exhaustion or will they take a break and receive some shocks? ~ Let’s find out!
