A restriction

Gaining more of your bearings as you watch over Sam sleeping peaceful, you decide to stand up and maybe start making breakfast for when she wakes up. However, when you stand, you become immediately aware of something... off. You hear the tiny clank of metal down below, where your dick is. You pull down your pajama pants to see a chastity cage, padlock and all, locked on your dick. It's pink color emasculated you further, even just finding out about this. Overcome with confusion, you wonder if Sam did this to you in your sleep. You bring your hand to the cage, feeling your weighty balls underneath your forcibly limp penis, toying with it a bit. You immediately regret this decision when you're met with a very uncomfortable kind of pain, when your dick tries to get hard. You can feel it struggling to grow inside the confines of the cage, and groan. Why was this happening to you?

"Good morning sleepyhead." You hear from behind you, in a familiar voice. It's Sam, and she leans over to you to cuddle you slightly from the bed, face pressed to you back in a half-asleep fashion.

"Hey sweetie... uh.... did you put this thing on me last night?" You say, gesturing to the cage.

Sam must be familiar with it somehow because she doesn't look directly, simply says, "The cage? Baby you've been wearing it for months now, don't you remember? You must have had a bad dream or something, "

Your heart rate starts to speed up. Months? What the hell? How did all this change while you were asleep? "Well... when do you think I can be let out?" you ask hesitantly.
