Some may know this slave can't orgasm, but it does get ridiculously wet.
First solo video... a spur of the moment one with a little insight into its life, service, etc. Its Masters sent it upstairs so they could enjoy valentines night. It masturbated for the whole time.
It does this daily, often a few times throughout the day, as a certain reminder to itself of what it is, and admittedly out of an anxiety that if it isn't touched sexually, it may lose its drive and become less usable/less worth using.

Video taken from its dog bed where it sleeps in Their room.
