Later that night at Sir’s house a new guest

 After messaging a random guy W/we have never met before on an adult dating site my Master invited a guest over for a blow job.
Really nervous i waited patiently on the lounge wearing just my underwear a bra and a black singlet top, i honestly believed he was just another “all talk internet guy who has a wank and no longer requires meeting me”
Sir handed me my blindfold and collar and instructed me to put them both on and then reminded me that tonight would just be me giving O/our guest a blow job and that there would be no sex involved.
Honestly i was a little disappointed to hear that the guest would not be fucking me, i always blow guys and put a lot of effort in to my blow jobs and feel that the guests are not putting in enough effort on their side.
Sitting on the lounge i placed on my blindfold and collar and sat quietly awaiting Sir’s instructions.
The guest knocked on the door and Sir went straight to let him in, listening out for as much as i could all i could make out was that Sir was speaking to O/our guest and informing him of the rules and reminding him that there will be video from the waist down.
Master never lets guest hurt me or Dominate me, after all i am His property and as Sir says quite often “That is My job” and “i am His girl”.
The guest walked into the lounge room and toward me, i sat and waited for Sir’s instructions with my heart beating a hundred miles an hour.
Just hoping Sir would say something soon. Silence and a blindfold is pure torture!
Sir said to O/our guest “she likes to be called a slut, she likes to swallow and she loves to be treated like a nasty little slut”
Sir instructed O/our guest to stand in front of me with his pants off, i was impressed his cock was long and smelt fresh like soap and that made me want to suck it.
Taking O/our guests cock into my mouth was great; he was clean and had freshly shaven balls.
He touched my breast from the outside of my shirt while i ran my warm wet tongue along the bottom of his long cock, i swirled my tongue around the head of his cock and sucked him as deep as i could get him just sitting his cock on my tongue so i could feel it swell in my mouth.
“do you like his cock slut” said Sir “yes Sir” i replied happily, i sucked his cock for a good ten minutes trying to get him hard, it was a long cock and i took it all the way like a good little slut making sure to let it hit the back of my throat and hold it there for moments at a time.
Sir asked me to remove my blindfold and i did a bad thing by pretending i did not hear His instructions, regardless Sir took the blindfold off me Himself. Still sucking O/our guests cock i avoided looking up or eye contact with him.
Sir ordered me to look into the video camera as i was blowing O/our guest, so while i licked his balls i made sure i stared right into the camera lens for my Master.
Feeling so nasty and secretly wanting this blowjob to turn into a full blown threesome i reached over and stroked Sir’s cock.
Trying to pull His pants aside i accidentally scratched Sir with my nail and totally killed any chance of that happening unfortunately.
Eager to make O/our guest cum i licked my hand covering it in saliva and started to stroke his cock while i licked his fresh shaven cum filled balls, they were so smooth and warm, i really enjoyed using my mouth to play with them.
Swirling my tongue around them moaning and answering Sir’s question’s
Sir “you like being a nasty little slut don’t you” me “i love being YOUR nasty little slut Sir”
While keeping eye contact i grinned a cheeky grin and continued to stroke his hardening long cock.
Sir asked O/our guest if he liked to be rimmed and he responded with a yes as quick as he could, Sir then asked me if i wanted to rim O/our guest’s ass like a nasty little slut?
Cheekily i responded, “if i am not allowed to be fucked why should i lick his ass?” Sir responded “because I am telling you too” i know better then to ignore my Masters orders so i sucked his cock nice and deep and slow then let it slide out of my mouth, i got on my knees and made my way around O/our guest placing my hand on his arse he bent over and i examined his arse to make sure it was clean. It was fresh and cleaned and again smelt like soap so i knew i would not need to safe word this situation.
Slowly i dragged my warm wet and soft tongue around his anus teasing him and placed my hand between his legs and around his cock and stroked slowly, i then inserted my slutty sub tongue into his arse.
O/our guest loudly groaned “oh baby” and i knew he was enjoying my nasty little tongue fuck, his cock hardened in my hand his thick sticky pre cum in my palm.
It turned me on knowing that it was my nasty tongue that got his long cock hard so i made sure to do a great job.
Long slow strong strokes from my warm wet tongue and at the same time slowly stroking his cock in my pre cum covered hand and then tongue fucking his ass like a good little slut.
After a while of rimming, tongue fucking and massaging our guests cock and balls, i sat up and Sir allowed me to go back into my cock sucking position where i waited eagerly for him to shove his cock down my throat.
Sir  approached me leant down over me and pulled my underwear aside where He then felt my pussy, showing off how wet and turned on i get, this was a huge tease for me knowing
Sir had already decided i was not to be fucked tonight.

O/our guest then asked my Master if i was wet so Sir inserted two fingers inside my dripping slutty pussy to ensure O/our guest that i was turned on and that i was wet, “so wet her juices are running down her leg” said Sir.
Removing his fingers Sir then made me hold open my mouth where he slid His fingers into my mouth for me to suck them clean. Sir then allowed me to climb up onto the lounge to sit comfortably after giving our guest his promised oral, winding down and feeling vulnerable without the safety of my blind fold. Sir ordered me to show off His property so i promptly and nervously removed my underwear making sure to avoid any eye contact i laid back and opened my legs wide and displayed my smooth eager pussy for O/our guest’s viewing pleasure.
Master gave O/our guest permission to touch my pussy and instantly he came forward and fingered me, the fact Sir had allowed a stranger to feel my insides turned me on and i loved the fact a total stranger was exploring my insides so i started to moan and grind my juicy pussy along his hand fucking his fingers.
What Master did next came as a complete and unexpected surprise to me, Sir asked O/our guest if he would like to go down on me, and without a second thought O/our guest replied with “I would love too” and for the first time ever, Sir gave a guest permission to go down on me.
Completely shocked and wearing the most obvious “what the hell is happening here” look on my face i kept my eyes down looking at the floor.
Sir ordered me to stay lying on my back along the lounge where O/our guest dove straight in kneeling on the floor by the lounge, he started to lick my clit with his wet unknown tongue and without warning inserted his fingers inside me probing at my pussy and getting familiar again with my insides.
It felt hot and i was dripping wet and so turned on, this has never happened before only my Master had ever gone down on me in a session, Master has given me oral in front of many in O/our sessions but this, this was a whole new experience.
Feeling Sir’s eyes on me while this stranger was thrusting his fingers inside me and stroking his wet tongue over my clit had me wild and wanting more, so many dirty slutty thoughts went through my mind, i started grinding my wet throbbing clit into his mouth and slowly riding his fingers, i placed my hand on his head to run my fingers through his hair and that was it, the moment i realized i couldn’t cum.
His head wasn’t Sir’s head, his hair did not feel the same, Knowing Sir stood there watching was so hot but there was no way this guy going down on me could do what Sir does to me.
So i moaned aloud and continued to ride his fingers i loved that he was moaning and enjoying it, i love showing myself off as Sir’s girl, His property His sex toy.
After about five minutes Sir ends the oral and sends me back onto my knees on the floor to service O/our guest properly.
On my knees on the floor i looked up at O/our guest and asked him for his cum, i told him i wanted to feel it in my mouth, sliding down my slutty throat, i told him i love to swallow cum,
He took an elastic band from his wrist and wrapped it around his cock and balls twice and then slid his cock down my slutty eager throat, i clutched his ass with both hands and pulled him in deeper showing him i wanted it deep, i did not let him see but i gagged and almost vomited twice.
Feeling his cock harden down the back of my throat and tasting his juicy thick pre cum got me dripping wet again.
O/our guest called me baby and darling, he was being way to sweet and groping at my breast, i slipped my arms out from the singlet top i was wearing and showed him my breast he felt them and lightly squeezed my nipples, it felt good, but no way was it as good as Sir does it, Sir pinches them, twists them and makes me moan in both pleasure and pain, that is how breast should be handled, but regardless it still felt good and i know my Master is the only person to Man handle me.
Kneeling under O/our guest looking up at him i asked him to cum in my mouth so he started to stroke his cock above my face getting faster and breathing heavy.
With that i did what i always do, i stuck out my tongue holding my mouth open wide right at the head of his cock waiting eagerly for him to blow his hot load of thick juicy cum into my mouth.
He blew all over my tongue; it was a lot of cum it was great, i felt so nasty and slutty.
Wrapping my mouth around his bulging cock i sucked it clean, milking every last drop of cum from him, knowing my Master was waiting i looked up and stuck my tongue out showing Sir and His camera the load of cum in my mouth.
Sir ordered me to swallow the cum of a total stranger and i did it so happily, opening my mouth after to show that i swallowed every drop like a good little cum bucket.
When i saw Sir was happy with my efforts i returned to O/our guests cock to suck it clean again.
It is an awesome feeling i enjoy with a guy when he can wind down and go soft in my mouth after i have milked his cock of cum.
After a few short words and a thank you O/our guest asked Sir if He wanted him to finish me off and make me cum.
Sir responded, “No that is my job”.
It was another of those awesome moments that make me love being Sir’s girl so much, i love that not only i but also my orgasms belong to Sir solely. i am indeed a lucky girl.
Sir’s sub slut.
