I opened my eyes and searched my thoughts for answers to the feeling that was confusing my mind, there was this more than warm feeling sending an erotic sensation between my legs. Blurry eyed I look down towards my crotch to see Jan with my cock in her mouth; she senses me awake and looks up to meet my gaze. She takes her lips from my cock and takes a sip from a glass she had in her hand. Then she returns her mouth onto my cock and the heat from the hot water she had just put in her mouth almost burns as she runs her mouth down my shaft letting the hot water heat my cock and then dribble onto my balls. What a feeling; I just laid my head back on the pillow and closed my eyes to enjoy the pleasure. Then with the urge to run my fingers through her hair I lifted my arms which I had above my head only to find they were tied to the head of the bed. I then went to move my legs and found them too were bound to the bottom of the bed. “Ok, what’s going on” I said. “Whatever I want to” she said “and there’s nothing you can do about it. Then she grabs a black scarf from the dresser draw and wrap’s it around my head as a blindfold. The Television was going and the sound from it made it impossible to hear what else was going on around me, it gave me a sense of excitement but there was also the fear of not knowing what was going on. I wasn’t even able to tell if Jan was in the room when she didn’t make a noise or even if there was anyone else there as well. “Where’s Len” I asked, wondering if he was in on this little charade. “Oh he’s around, he’ll be coming back shortly, or should I say coming in shortly” she replied with a chuckle in her tone. I heard some movement and then the bed moved as if someone had lent on it, I listened trying to work out what was going on. Next I hear a throaty breathing accompanied by movement of the bed. “Awe...yes” came from Jan and I quickly realised she was getting cock and it wasn’t mine. “C’mon you two....fuck this isn’t fair, I want to watch”. I could only imagine that Jan was getting fucked from behind by Len while she leaned on the bed but in fact I had no idea, it was a pleasant torture. My cock was getting hard from the thoughts going through my mind and then I feel the warmth of Jan’s lips sliding over my knob. I could hear the slurping of Jan’s pussy getting slammed by Lens cock as her mouth jarred on my cock from the thrusts she was getting from behind. Then there was no movement and the only sound again was the TV, once again a little movement on the bed and the warm lips sucked onto my softening cock and stirred it back to life. Up and down on my knob a couple of times and then slid slowly right to the bottom of my shaft, back up and off the knob with a pop. With a jolt I said “What the fuck!!....who the fuck was that....that better not be you Len, I’ll fucking kill you”. You see I knew it wasn’t Jan because she has never been able to deep throat me...ever!! I could hear Jan chuckling...noo, she was almost pissing herself laughing. Next thing I felt was someone walking on the bed and then my cock being rubbed on what I figured was Jan’s pussy; with an instant erection she was able to lower herself it. As I enjoyed the pleasure my cock was getting I thought I still didn’t know where Len was so I said “where the fuck are you Len, are you here”. Then I was dumbfounded as Jan replied from across the room “he’s over here with me but his mouth is full at the moment. “Who the fuck is on my cock” I replied sounding more than a little excited. Then it wasn’t just Jan laughing, I heard Len and another female laugh as she pumped herself up and down on my cock. “I know that laugh” I said “but I can’t put a face to it, who is it?” “You will have to work that out for yourself” Len said and Jan came back with “Ya, and if you can tell who’s on your cock I’ll know you’ve fucked her before. “What colours your hair” I said trying to get her to say something so I could heard her voice. All I got back was faster and heavier breathing as she quickened her hip thrusts on my cock. “Keep that up and your gonna get creamed honey” but before a got a shot off she slowed her pace and leant forward putting her hands on my shoulders. I got a strange but familiar smell as she bent down and kissed me on the lips. Funny how your senses get sharper when you can’t see; I knew the smell like I knew her laugh but for the hell of me I couldn’t work out who she was. Then I thought how Jan didn’t go for the idea of me fucking another woman and obviously she had set this up so it had to be someone she knew and trusted. Besides, this had all been arranged while I was still asleep that morning so she was from nearby as well. Then my balls were being gently fondled and I still had two hands on my shoulders so I knew it was someone else. “That better not be you playing with my nuts Len” I said. “ I wouldn’t touch your nuts with Lisa’s hands” was his reply. LISA?? I don’t know any Lisa I thought to myself. “Ok smartass, obviously your trying to put me off the track because we don’t know any Lisa and I know Jan wouldn’t let someone she doesn’t know on my cock”. Then there was laughter again and I listened intently to this woman, now sitting still on my cock to try and put a face to the laugh. I could tell she was bigger than Jan by her weight, or fatter maybe, I figured she was taller because when she bent over me while mounted on my cock her head was closer to my face than when Jan was on top of me. Another little kiss on the lips and she raised her pussy of my cock and repositioned herself putting her pussy on my mouth, I licked, and it was nice pussy. Then I felt the warmth of another pussy sliding down the shaft of my cock. “Fuck, I’ve died and gone to heaven” I thought to myself. Jan riding my cock while another woman is sitting on my face, I didn’t think that would happen in my lifetime. But it did and fuck was I enjoying it. The thought of them getting it on together went fleeting through my mind but I really did know that was never going to happen. With more of a groan than words Jan says she is going to cum and she grinds her pussy hard onto my cock sending me over the edge at the same time. I involuntary sucked harder and faster on the unknown pussy on my face and she lets go with a groan and pushes her pussy harder onto my face as she cums as well. Now that’s what I call a threesome, it doesn’t get better than that, all three over the edge at almost the same time....fuck!!! “Hey Ladies, I’m feeling a bit left out over here” “hang on to ya hardon we will fix you right up” was the reply from the unknown woman. All I could think of when I heard her voice again was “I don’t fucking believe it!!!” and as I was laying there in disbelief of who I thought was just sitting on my face the two girls got up and left the bed to go to Len and I was left on my own. I was being bugged with the thought of if I was right and that was who I thought it was; but now I was being bugged by something else, the sounds of the two girls giving Len a good fucking and I couldn’t watch. And even worse I got another hardon and couldn’t even get my hand to it to give it a rub while I listened. Len had himself that horny from watching the girls fuck me that it was only a few minutes and as it turned out, let go his load into the mystery lady because she said “Fuck, what a load, you must have needed that” That voice I thought, that has got to be her but fuck, I still don't believe it. Then what seemed like a second later a set of warm lips were pressed on mine and I could feel fingers pulling the blindfold loose. I was waiting for my eyes to adjust to the light as it was pulled away, waiting to see Jan’s eyes looking into mine. As her lips parted from mine and my eyes focused I soon realised the eyes I was looking into weren’t Jan’s and I was right, the voice I heard did belong to the woman I thought I had recognised. Then I heard Jan say “ I always knew you wanted to fuck my sister, hope you enjoyed it because it’ll never happen again”
