My cousin the night before thanksgiving SeXStoRY

Well my cousin came to visit for Thanksgiving she is a year younger than my s****r so 10 years younger than me and i guess my s****r has not been keeping our secret because my cousin (sara) knew all about how i have been my s****rs slave for years now! I didnt know this at first so i let sara stay in my appartment last night thinking we would just have some fun girl chat. After chatting awhile she made a move to kiss me i let her because she is soooo sexy she is in track and volleyball in school and has the most amazing D-cup breasts. Before i knew it i was naked and sara was still fully clothed. She slowly turned me around kissing my neck and shoulders then she slowly pulled my arms behind my back so gently i suspected nothing. I was sooo turned on at that point i didnt feel her put the handcuffs on my wrists I was shocked feeling the cold steel against my wrists i struggled before she took my ponytail in her hands and jerked back hard. Then she leaned towards my ear and whispered about how my s****r had told her everything a couple of years ago and she said she couldnt wait to use me. I was shocked and soooooo turned on at that moment then she pushes me to my knees. Sara then told me i better be prepared because she loves inflicting pain and humiliation. I was scared at that point because she is very strong and well im not! Sara then pushed me face first to the floor and ordered me to lick her feet clean! Still a bit shocked i hesitated my s****r had never had me clean her feet so Mistress Sara (that is how she now told me to address her) jerked my head up by my hair and slapped my face soooooo hard then shoved me back down still scared a bit i was soaking wet and scared so i immediately started licking for all i was worth! After licking both feet for what seemed like forever Mistress Sara jerked me up again dragging me by my hair to her suitcase bending over she began to pull several things out of her bag. The first of which was a collar and leash which she placed on my neck very tightly making it hard to breathe. She then lead me to the bathroom me crawling on my knees which were burning by now she then lifted her skirt pulling down her panties she sat on the toilet and peed. As soon as she was done she pulled the leash and my head to the toilet shoving my face in her pussy she ordered me to clean her! Slapping my face hard again i quickly complied licking her pussy cleaning off the pee and licking her whole clit. She ground her pussy against my face smothering me in her very wet pussy fucking my tongue hard and fast i was having a hard time breathing but Mistress Sara kept going as i was about to pass out she finally came covering my face in her girl cum! After a short rest She stood up forcing my head in the toilet which was filled with her pee and the cum that i didnt drink she wrapped the leash around the back of the toilet then tied it to the other side of the toilet keeping my head in the toilet. She told me she would be back in a few mins. It seemed like forever but i heard he walk back in to the bathroom and felt her grab my hips as she sank down behind me i felt a huge strapon slide in my very wet cunt i screamed in the toilet and i just heard Mistress Sara laugh at me! My arms still cuffed behind my back and my head stuck in the toilet she fucked me soooo hard and fast pounding my head in the toilet against the rim! I came immediately and kept cumminmg over and over after a long fuck i felt Mistress Sara pull the huge strapon out of me and come stand over my head where she untied my collar and then f***ed my face further in the toilet ordering me to lap it up like the doggie bitch i am! She started spanking me soo hard till i complied lapping up the piss water like a doggie. After a few mins of lapping she yanked my leash dragging me behind her Mistress Sara was now naked i saw with the huge strapon still on but i was amazed she had a 6 pack stomach her breasts were perfect almost no sag of the huge D-cups I was in awe of her thats why i didnt see her hand coming towards me as she slapped me sooo hard i saw stars. Yelling to me she told me to pay attention as she dragged me by my leash out of the bathroom to my bedroom. She lifted me like i was nothing her arms were sooo amazingly strong and tight i felt in awe of this goddess. She tossed me on my bed my arms now pinned beneath me and still cuffed she grabbed the leash and pulled my head onto the huge strapon sucking for all i was worth. While Mistress Sara told me how pathetic i was and how i was just a slave cunt for her pleasure she told me she would bring over boys girls and even dogs to use me cause i was just her slave cunt her property. After a few mins she pulled the huge strapon out of my mouth and took it off pushing me to the center of the bed she straddled my head lowering her amazing pussy to my tongue riding my face fucking my tongue soo hard smothering my face not able to breathe Mistress Sara continued to fuck my face allowing me to breathe occasionaly as she grabbed my hair fucking my face till she finally came again on my tongue! She finally got off me slapping me hard back and forth calling me her whore her bitch her slut her property she hit me on the lip splitting my lip open when she finally stopped. Mistress Sara then laid down beside me and quickly fell asl**p leaving me handcuffed and collared. She woke up a few times through out the night riding my face cumming again and again through out the night. When morning rolled around she realeased me telling me to tell my f****y that my split lip was an accident when i fell! She then promised we werent done she was here for a few more nights!
