It feels like your dreams have come true

You stand in silence. Your sister has just offered to be your keyholder. Not in your wildest fantasies did you ever imagine something like this. Your beautiful sister, the girl who you have jerked off to more than anyone in your life, is offering to be responsible for the key to your chastity cage. You had said to her that it was a stupid impulse buy. Of course, you never dared to put it on, but the thought of being put in chastity had been one of your biggest kinks ever since you discovered it years ago.

"This wasn't a question John." Your thoughts are interrupted by your sister. "I'm not asking if you want to be caged by me. I'm telling you that you are going to be caged by me. Unless you want me to tell everything that has happened today to Mom and Dad." Your sister says, smirking.

She has you cornered and she knows it. There's no way out of this. But then again, this is a once in a lifetime opportunity, and you would be foolish not to take it.

"Then again, it looks like I'm not the only one excited about this" she says, gesturing towards the tent that your cock has made in your sweatpants.

You blush once again, embarrassed by the entire situation. But it is true that you are hard as a rock, and you feel like you should pinch yourself to see if you are dreaming.

"Here's what you are going to do John. You are going to go back in your room and take care of that tent of yours. Then once you are nice and soft, I want this cage on you" Emily says as she tosses the cage to you. Flustered as you are you struggle to catch it, which causes her to giggle. "When this cage is on you, I want you back in here with the key. And you know what happens if you don't do as I say."

You try to say something, but the words fail you, as you leave her room and go back to yours. Your cock is aching like never before, as you sit down in your chair, and try to make sense of this whole situation. Your sister just told you to go and jerk off. She just told you to put a chastity cage on, and give the key to her. You know you have no other choice but to do as she says, and besides, you have never been as horny as you are right now. You have to jerk off to clear your mind.

As you pull your cock out for the second time today, you don't even need any porn to get you off this time. The only thing in your mind is Emily. Just as you grip your cock, the door opens again, and Emily walks in. She looks at your cock and grins, and then tosses a pink cloth next to you.

"Here's a little gift for you. Seeing as it's the last orgasm you'll have for quite a while." She laughs and exits the room.

You look at what she threw on your floor. It wasn't a cloth, it was a pair of pink panties. And they are sticky.

It doesn't even take you a minute to cum.
