Here I am confused, bewildered and scared to death. How did I get here? Why had I consented to be treated this way? I feel like quite a fool, deceived by my weakness for a female facesitting, the all compelling sight of a full bottom and a strong willed woman. No not merely a woman, but a cruel Dominatrix, a Mistress. I am alone, all tied up, stripped naked with no means of escape. Your ass hovers right above my upturned and unsuspecting face. I realize your naked ass is in my face. “Oh no! Not again!” I plead. Your ass is round and quite intimidating, and now it is all I can see…or smell. You see my terrified look and laugh evilly. Lick me until I come or else I’ll sit on your face until you expire. Either way I’m going to enjoy this.” The only sound is my whimper as your sexy ass comes slamming down on to my face. My nose is wedged deep into your anus, while your pussy is rested on my waiting tongue. You wiggle around to find the most comfortable position, the weight of your heavy bottom shifting around on my poor face. My small head almost completely engulfed in your threatening butt cheeks. You sit unconcerned full weight, anticipating the gentle services of my tongue. "Don't make it a long night bitch!” you warn. “Make me gush all over your face.” As I lap away at your bulging clit, I can hear the growing panting from you. Your ass jiggles on my face, as you rocked back and forth to the soothing feel of my wet tongue. Tightly riding my face, you move as if galloping for your life, the swollen knot of your clit caressing the tongue trapped deep inside you. Forcing your body down to mold with my face, sealed beneath the crushing force of your round derriere you glue my face to your warm gushing slit. Suddenly you cum in one great spurts your vaginal liquid, pouring its way mercilessly onto my trapped face. Your goo seeps into my mouth, your repugnant taste, seemingly unbearable. "Lick me clean bitch!” you order. "Oooohhhh, that's right, I have trained you to be a very good little ass cunt licker. That's right bitch, I want you to swallow all my fuck juice." You lean your weight forward, cutting off the supply of air I so desperately need. With my nose crammed up your ass, I am struggling and gasping for breath. After having used my face to pleasure yourself to an intense orgasm, satisfied you slowly climb off. Looking down seeing my very sticky, pussy fragrant and sweat drenched face, laughing you turn and leave the room. Leaving me all tied up and completely drenched in your pussy juice.
