It was winter in the city and me and my gf of three years were relaxing on the couch with the fire running. There was very little to do causing the levels of boredom to rise in both of us when my gf who we will call marcy says i know this sounds childish but would you like to play truth or dare? The boredom of the day so far causes me to say yes this is when marcy starts to smile and wants to start the game. 

  Marcy starts the game by asking me truth or dare in which I answer truth. When she hears me answer with truth she asks immediately what is your kinkiest fantasy. This first truth already being this sexual catches me off guard and in turn causes me to blurt out the first thing on my mind which was being dominated which honestly was always kind of something i wanted to try but never could ask marcy. The moment she hears this there is a kinda smirk that arises on her face almost as if she likes this idea. Then I ask her truth or dare which she answers dare while caressing my leg causing an even stronger feeling of tension between me and her. The sexual tension that is being caused determines the dare I gave her which was to go change into any sexy outfit she wanted. Marcy then got up and walked into the bedroom only coming out a few moments later wearing a pair of black boots the rest of her was completely exposed. When she got closer I could see everything in great detail with her perky A cups with little pink nipples as well as her tight little pussy. The arrival of her caused me to get an immediate erection which she noticed immediately. When we restarted the game I decided to answer dare in which she dared me to get on my knees and eat her tight little pussy for 5 minutes.

 The moment I started eating her out the horniness I was feeling only kept rising. The taste of her perfect tight vagina was starting to drive me crazy when she calls it had been 5 minutes already i wanted to keep going. This is when i asked marcy in which she answer truth. The moments before caused me to be so horny that I decided to ask her what was one thing she always wanted to do to me or with me. Marcy ponders the question for a second in which she answers I kinda wonder what it would be like to be your keyholder. This term keyholder was something new to me so i asked her what is that which in turn she responds by saying a keyholder would make me be able to control when or if you have an orgasm and you will wear a chastity cage on your penis that will make you not able to get an erection. This idea Marcy had was new to me but honestly kinda turned me on having her in control of such a bodily function. The horniness got to me and I made the decision to say let's do it. Marcy in shock says what you want me to put you in chastity in which i answer yes.

   Mary, excited about this thought, looks on her phone and finds a sex shop 4 miles from our place and asks are you sure we can try and go get a chastity cage for you right now in which I answer let's go. The drive to the sex shop was short and once we arrived we walked in and goto the front desk asking if they had any kind of chastity cages in stock which to our shock they had a fairly large selection. The employee points on specific ones but there is only one that catches marcy’s eye. The chastity cage she liked was a small pink cage with a shocking function once she points it out and looks at me as if she's asking permission to get that one in which I said you're the one taking control of this it is up to you. We walk out of the shop with the pink cage and drive home. When we get home we walk in and open the packaging with the excitement of this whole situation marcy immediately goes put it on put it on. When I realize how excited she is I comply instantly by forcing my penis into the cage and locking it.

  The moment I gave her the keys her face lightened up with excitement as I wondered if this was really a good idea. When i finish this thought i she start to speak “ok so now that i have your keys and completely control when and if you orgasm i wanna be completely honest with you the moment you said you liked the thought of being dominated got me thinking about my fantasies of doing this to you, from now on you will be my slave doing as a wish if you ever want to have another orgasm”. This statement from her caught me off guard but I hate to admit it actually turned me on even more. This is when she orders me to get on my knees and start to eat her tight little pussy again but this time she never stopped me she kept making me until I heard her have one of the biggest orgasms she has ever had. When she finally settled down she told me “this is your life for now the only way you will have an orgasm is by making me happy and failing to do so will cause you to be punished”. This statement really makes me ponder was putting this chastity cage on really a good idea
