Teased and edged [24 Variants] (Pixiv Fanbox)

What a cruel fate! This trainee has been tied and equipped with a milking machine. The machine’s interior is lined with ultra-slippery silicone tentacles that caress every inch of their cock. Strong enough to make them feel intense pleasure but too weak to make them cum. Completely unable to cum, the trainee has to watch a pretty girl tease him by pleasuring herself. Once the session is over, the trainee will be equipped with a chastity device until further notice.
