Futago Shimai Semen Tank
双子姉妹ザーメンタンク
Twin sisters find themselves trapped in a strange facility where their bodies are used to produce a mysterious substance. They are subjected to repeated experiments that drain their energy and vitality, turning them into living tanks for semen collection. The sisters must endure the relentless procedures while trying to find a way to escape their captors.
The facility's operators have no intention of letting them go, and the sisters' bond is tested as they face physical and psychological torment. Each day brings new horrors, and their hope for freedom dwindles as they realize the true extent of their exploitation.
