I have an obligation to take care of my master until I make him cum with my hands while handcuffed. I am naked but my collar and my leash remind me that I have instructions to follow. I sit astride the leg of my master who is lying in front of me. I start to take care of him with one then two hands, my lips itch, I'm so hungry for his cock, I approach my mouth and I hold back from taking him, but I flow with pleasure and desire on his leg. My tongue touches it shyly. Then a little more, then after authorization from him, I let my mouth engulf him. My breasts brush his thigh and my pussy his leg, my wetness soaks him. My tongue slowly tastes his penis then I resume the game with my hands, before taking it entirely in my mouth. I have to get back to manual work, that’s the order. I obey and allow myself a few deviations from time to time with my mouth... I make it squirt on my fingers which respect it by licking it gently.
