A chastity cage

You had no idea what it was. It was a small bird cage only shaped like a small, slightly curved cylinder.

"What is that Margery?" You were completely clueless.

"This, my bad boy, is to ensure we don't have anymore accidents. Here let me show you how it works."

She took a whole of your spent cock and attached a ring around the base of it and then snapped it shut with the larger portion. She then locked it using a tiny key, it it snugly around your cock, the cold metal touching your skin. She took the key and attached it to small anklet at her ankle.

"There we go. Now we've eliminated the possibility of any accidents."

She looked at you expectantly but you were too tongue tied and confused to respond.

"Tommen! I just helped you, where are your manners? Do you need to be punished again?"

"Oh I'm so sorry Margery! Thank you for giving me this so I can avoid future accidents." You quickly reply hoping you weren't going to get spanked again.

She held your eyes for a moment with her piercing ones and then nodded. "You are young and need training but you seem genuinely eager to please your queen so I'll give you a pass this time."

"Thank you." You quickly reply, sometimes you didn't always get your lessons but once you got them you didn't forget.

"Now..." Margery said and you wondered just what else was going to go on during your wedding night!
