To understand this story, You must realize that i am a slave to both Master Carl and Mistress Ann. Master and Mistress are also brother and sister. i have been owned by Mistress for over 21 years and Master for 18 years. During the course of those years, they have used and "abused" me in many different ways. i have always considered myself to be so lucky to be loved and cherished by these 2 wonderful people. Recently they arrived home at the same time. As ususal i met them both at the door. i was nude except for my collar and cuffs ( i am always kept this way in the house). i wear the cuffs all the time so that they may attach the rings and tie me quickly. i assumed the submissive position that i have be taught; on my knees, my hands laced behind my head, my breasts thrust outward and my eyes respectfully lowered. Master came in front of me. i immediately reached for His zipper and undid His pants, freeing His cock. Once His cock was out i brought it to my lips. i always wear bright whorish red lipstick. Master licks to see those lips wrapped around His cock. My mouth worked hard on His cock. As i sucked Him, Mistress came behind me and with one hand started to play with my nipples and used the other hand to pull my hair. Master also started grabbing at my hair. The pain was pleasant. In now time, i felt my pussy starting to throb. i fondled Master's balls and knew from my touch, that He was ready to cum. Mistress told Him to cum on my face, so that She could lick it off my face. Master could only grunt because He was almost there. Mistress started to pull and painfully twist with both hands on my nipples now. i reached between my legs and as soon as i touched my clit, i exploded. My hips thrust as i came. i screamed on to Master's cock and He erupted. After the first shot, He pulled out and i grabbed His cock and pumped His hot cum on to my face. He was very full and shot wave after wave of hot sticky cum on me. In time it started to run down my face dripping from my chin on to my hardened nipples. i continued to suck Him until He started to soften. He then sat down on a chair to watch Mistress and i. Mistress stopped pulling on my nipples long enough to slowly take off Her clothes. Mistress knows how aroused i get watching Her strip like that. She is an office manager, which means She must dress conservatively. But underneath Her "proper" outfit is the underwear and panties of a slut Her panties and bra matched...nice black lace. Her panties were french cut. Neither Mistress nor i like thongs (floss for Your asshole she calls them). i think She looks much sexier in black lace panties, where Her trimmed hair is just barely visible. Once She is out of Her skirt and blouse, panties and bra, She stands there in just Her stockings and garter. She knows She is inflaming both Master & i. Slowly She comes towards me and starts to lick my face. Mmmmm She sighs as She tastes Her brother's cum from my face. i love the feel of Her tongue on my face. She looks at me and says: "Each time we cum on you, we claim You with out scent. Now i want my cum on your face." She presses Her hips close to my face, as i put my tongue to Her clit. i reach behind Her and start to play with Her ass as She presses hard into my face. my tongue goes into Her wet cunt and i start to tongue fuck Her. She was very excited from watching Her brother and i play, so i know Her cum will happened quickly. As i tongue fuck Her cunt, i start to spread Her ass apart and gently put my finger on to the tip of Her puckered asshole. Slowly i start to push my finger inside Her asshole. Once inside Her asshole, i try to find a rhythm between my tongue and finger. Soon i am tongue fucking Her cunt, as i finger fucked Her asshole. Finally She erupts into a hard cum. Her cum son drenches my face. She rests on my face as i suck the remains of Her cum, Her pussy still throbbing. Finally She leans Her body on mine. Just as She does this, i feel hot cum hitting my face from the side. i was so lost in Mistress' cum that i did not see that Master was hard again and was jerking off. His cum happened just after Mistress's cum. He directed His cock so that His cum hit me on the side. Mistress just smiled and wiped Her cunt on my face. "There slut, now you are marked by us both. We are having company tonight and i want them to smell our cum on your face. Now get on your hands and knees. you are going to be tested tonight!" Once like that, i could only wonder what they had planned........
