Trust is an essential part of all relationships, without trust the foundation of the relationship is lost and if the foundations of something fail the entire building comes crashing down. However some secrets are harder to share with your other half than others, you see you had always had a love for women's clothing, you embraced your fetish which led you down to the road to becoming a sissy - well privately at least. Deep down you wanted to embrace your sissy side more fully, for longer and be able to have your own knickers instead of having to sneakily wear your girlfriends.
You have a ring in your pocket, it is of course for your girlfriend and you deeply hope she will accept your hand in marriage. Being the gentleman that you are and realising the importance of trust you realised that you had to tell her about your 'other' self, the feminine side of yourself. You had managed to work up the courage after a few beers and told her your most trusted of secrets hoping she would be accepting and have you in a dress by the end of the evening but real life isn't like the porn movies. At first she freaked out and assumed you were gay but you reassured her and eventually she slowly became more accustomed to the idea.
What at first was her allowing you to wear knickers in the bedroom to give you a more pleasurable and harder orgasm but after being introduced to your porn collection became intrigued by the idea of sissy's and you couldn't believe your luck when you returned home from work to find shaving foam with a note explaining how your body hair was to become a thing of the past. Soon you were fully dressed as soon as you came through the door. your cock had become a clit which was kept under lock and key and your girlfriend took pleasure in riding your new 'sissy pussy' with the strap on she had purchased.
So here you are, your girlfriends sissy, with your cit locked away until she decides otherwise and it's locked away for good reason, you see you're a much more obedient sissy when your horny and helps your girlfriend to push you to the next level. You might be a sissy in her eyes but if you want to cum today you have to take a 50% chance that you will be a sissy in the eyes of the general public - how your girlfriend loves cruel games.
