Bust his balls pendulum style

描述 [POV Attack] (英语):
As he's restrained, you remove the bottom of the chair, exposing his heavy balls and hard cock. Walking behind him, you let go of the rope holding the satchel with metal balls and let it swing. Quickly, you swing it so hard into his balls that he shouts in pain but judging by how aroused and leaking he is, he's enjoying it.

人机对话 (英语):
Guess what time it is.

描述 [POV Victim] (英语):
Restrained to the chair, you feel the bottom of it being removed, exposing your heavy balls and hard cock. Hearing him walk behind you, you are unprepared for the heavy hit to your balls as you cry out in pain. Even so, your cock is hard and leaking like crazy.
