Chastity over night

For the first time my partner ( or should i call her Mistress ) asked
me to wear my penis cage all night and most of the day after. So far
i only had to wear it from time to time in the day for several hours,
usually before any reward or session. So i went to bed wearing it.
Even thow i felt a little nervous about knowing if i would manage
to sleep i wanted her to be pround of me in the morning. She had
left the key in the bathroom for me to unlock myself if ever i felt
unconfortable during the night. I knew i would do my best not to
use it. This was my first experience and when i woke up in the
morning, she asked me how i felt and slept. I told her i slept well
and it was a very interesting experience. Not only i had dreamt of
D/s senarios i noticed i could have my usual morning male stiffy
when waking up. I think i realised how much powerless and
vulnerable this made me feel and how it worked to be a perfect
strong reminder of who is in charge at home.
