Sissy Training - Bonus! - Chastity Draining
The goal is to have a good amount of time between when you cum and when it's possible to unlock your device. If you're a smoker, smoke a cigarette while your outside. Maybe return some text messages or just surf the internet. You need to go soft before you can take the chastity device off, right? Might as well spend it ouside.
Once your back in, hopefully enough time has passed that you've come back to your senses and know that deep inside you're nothing but a cum-guzzling slut. Carefully roll that condom off its cage and dump it into your mouth. Make sure you get your tongue in there and lick out every drop. You've worked hard for this, damnit!
Some of you might think that you're too smart for this, and you'll just take the condom off before you go and get the key. Of course, you can do that, but the cum that will still dripping from the cage and your clitty will at the very least make wearing pants sticky, and might even become embarrassing if you get stopped by a neighbor! Better not to risk it!
Keep doing this and you'll have nothing but anal-only orgasms filled with mouthfuls of cum!
