I look through the few possessions that I own, which isn't much, I gave master everything, even this house, the only things I have are a few personal items, most gifts from master, and the clothes that master makes me wear when in public and outfits for roleplay. He wants me to contribute to the local time capsule but what to put in there? It has to be something meaningful, something that tells people about life in the current day, something they can learn from. I look through what little I have, hoping to find something that would be perfect and please my master.

Wait, I know the perfect thing, it would be a big step and sign of love, trust and commitment. I open a drawer and lift out a small box, inside of which is the emergency spare key to my chastity cage, although I've never actually used it, this has always been a safety net. Maybe it's time to get rid of such a thing, I trust and love my master and want to serve him forever, putting this in the capsule would show my commitment to him.

My heart races as I walk up to the capsule, my hand gripping the small box, while my cock strains inside its cage, one that it is soon to be trapped inside even more so than before, as I give up the last piece of control over it, from now on only my master can decide to unlock me, even in an emergency. Although I'm nervous the thought of removing my last ounce of control excites me.

I slowly and gently lower it down into the container, part of me not wanting to let go. But I must, i must do this for my master, show him how much I love and trust him, show him how much I want to be his. I let go, a wave of relief flowing over me as I place it next to a strangely similar looking box. I walk over to my master, who puts his arm around my in a loving embrace.

"So what did you put in the time capsule?" I look up at him and smile as the container is lowered into the hole that it will be buried in for 100 years.

"My emergency key, I wanted to show you how much I trust you and how much I am yours." As he smiles in response to watch as the concrete is poured over and around the capsule, sealing it, and my key, away.

"That's interesting, I also put your key in there." Shock fills me as I look on in horror and my cock strains harder than ever as the capsule disappears from view, the keys to my cage lost for 100 years, my cock forever denied, my commitment to my master sealed forever. As my master holds me I feel strangely content, the uncertainty of when or if I'd be released disappearing and the feeling of commitment to my master, only makes me love him more. I wanted to take this step forward, to give master full and absolute control, to decide my fate, and he has. I wonder if he knew that I'd choose my key? Maybe this is what he wanted, he wanted me to make this step, one that I'm happy pleases him and if it does I feel glad that I made the right choice.

I wonder how people would react to seeing the sign of my commitment, trust and love 100 years from now? Would it inspire others or would they find it romantic? I lean my head against my master as we turn and walk away from my buried keys, ones now forever out of reach under the hard concrete. I smile slightly as we head home, my cock straining in its eternal frustration, as I hope that my master will relieve me tonight, my pleasure now solely in his control and dependent on him. Although he could just use my mouth, having taste what I could never have, or make me stroke his cock while my own goes forever untouched, hopefully I've earned a good fuck today but it is only for my master to decide.
