Chastity cage

"It’s a chastity cage Sansa after a while of having a boy locked away with no release they’ll do anything," said Cersei.

You look nervously at the queen then to Sansa begging with your eyes. "That sounds like fun can we put it on him now?" said Sansa. Cersei tells you to strip and stand in front of her. She locks the cage on your cock. Cersei asks Sansa if she wanted to keep the only key.
