Date: Thu, 01 Mar 2007 21:29:47 -0600 From: Ham Barker Subject: Grandpas Visit # 4 Bisexual Incest Mark used his machine in between his sex with the men,it was almost as though he liked it better than real dick.It was obvious that he was obsessed with the thing. When grandpa was pile driving his big dick in and out of me I could vision that machine ramming that big rubber dick insidein place of his dick. While he was fucking me one day I let it slip about the machine and grandpa insisted we take a look at it right then. "But Mark keeps the door locked grandpa."I said "No problem darlin."he said as he took my hand and led me naked to the door.In no time he had it open and we entered. "Wow,now that is some kind of gismo for sure.Get up there darlin and lets see how it works." Quickly I lay up on the stand and with my knees bent I spread my legs as I looked down at grandpa guiding the big cock between my legs and adjusted it. Mark had all kinds of lube and grandpa greased the thing well . "Skoot down honey,thats it."He said,as I watched the dick disapear inside my throbbing pussy. Grandpa set it on slow and I felt the heavenly thing begin to move inside me,I know a lot of the lust came from the fact it was taboo but I loved it all the same. Grandpa was looking at some of the other attachements,the a smile lit up his face as he stoped the machine and attached a second rubber dick,this one was green in color. It was on a seperate rod just below the first one,this one he adjusted and slid it up my ass.Again he set it on slow and when the dick went in my pussy the bottom one filled my ass at the same time. Grandpa moved beside me with the remote in his hand as he held out his dick to my mouth and I allowed him in.He began to face fuck me,all three of my holes had a dick going in and out at the same time,what a wonderful feeling. Then grandpa made the machine go faster,then even faster.I tried pulling my mouth from his cock but he held my head tight and turned speed up once again.The cocks were going wild inside my ass and pussy as he face fucked faster and faster as well. I could feel my orgasm building and building,never had I felt so aroused before.Then my mouth was being filled with warm silky cum.I was sobbing from excitement as I swallowed all of it. When grandpa removed his cock I cried out and jumped back from the dick's and fliped over on the floor as my juices spewed high in the sir and all over grandpa.I had never done that before and grandpa said it was what they called squirting. I will admit that I was scared that first time but was soon to learn to love it. I wondered if Mark used both the attachments.I was find out later. Mark had not been usuing the machine for a couple of weeks,the men had kept him to busy.It was odd how much I still enjoyed watching those guys have there way with him.At first it scared me a little,the way they got rough with him at times,but I soon saw that Mark loved the rough sex. One old guy had a bridle he would place on Marks head with a bit in his mouth.He would set on Marks ass with his cock buried deep and jerk on the reins as he fucked.But as I said,Mark seemed to love it. I caught him with the machine a couple of weeks later,grandpa had made me a key.Mark was naked of course and I watched silent ly as he peed in a glass and set it on the bench in front of the machine.I became excited as I saw him hooking up the botton dick along with the top one before squirting lube up his ass and over the rubber cocks. I was fingering myself as he backed up to the dicks and maneuvered himself till both dicks were started up his ass,He waited a minute or so then eased his ass back till both cocks were buried to the hilt,once his ass became used to the envaders he switched it on. Mark took the dicks slowly at first.his head back,eyes squinted and gritted his teeth,then he encreased the speed.As his ass was being reamed he took the glass of piss and began drinking it slowly till it was all gone. If I had not seen it with my own eyes I would not have believed it,his ass hole was stretched beyond reason and from the look on his face he was loving every minute of the action. I loved the feeling of one in each of my holes but just knew I could never try what Mark was doing. Without thinking I entered the room and eased myself beneath him and took hold of his dick,he glanced down at me but never flinched as I kissed the head of his dick before taking it in my mouth. Mark had a dick long enough to deep throat and I took full advantage of the fact,devouring every inch of his hard meat. Mark reach down and took hold of my head as he whispered brokingly,"Mm..iit..zi,ohh..Mittt..sszi." I felt his dick throb in my throat as he hands gripped my head tighter just before his cock erupted,shooting his boy cream straight to my stomach. After that day Mark invited me into his room often,he loved having his dick sucked while being deep fucked by the machine. I remember one guy that came about once a month,I swear he had the largest dick I have seen.It was not so much the length but the width.It was six inches long but must have been three inches across or maybe more. They had to lube it good in order to get it up Marks ass,but get it in they did. They guy like to slap the cheeks of Marks ass hard,I could hear the slapping noise out in the hall.My mom had came home and wanted to know what that noise was,so I showed her. "Oh my word,he will rip the boy open with that thing!"She gasped. "No he won't mom,they have done this several times before." My mom and I stood watching the two of them.We both thought it was really sexy when the guy attached the electro pads on the cheeks of Marks ass,it must have been set on pulsate becuse he time it shocked,Marks would jump and we could see his cheeks quiver. Mark could not cry out because he had a band around his face with a rubber ball stuffed in his mouth. The guy also had a strap which he lashed Marks back with adding to his sexual pain. By then I had my moms dress off and was on my knees with my face buried between her legs trying suck her pussy down my throat as she kept her eyes glued to the two inside the room. My mom was so wet my mouth was smeared with her juice as I sucked and ttonged her,then I felt her legs begin to quiver as I heard her gasp. "Oh Mitzi honey."And she was sagging downward to the floor where she lay with her legs spread and my mouth was once again devouring her. She hunched her ass up and down against my face as she moaned louder and louder,then she was squirting,not pee,but juices from her orgasm.She could produce even more juice thern I had and I loved it. I had already climaxed myself and the two of us lay naked on the floor gasping for air.I remmeber looking at Mark and the man with him,the guy had placed clothes pins on each od Marks nipples plus a dozen or so on his ball sac.It was really sexy to watch the pins flop around as the mans big cock pumped his ass. The guy had another thing in each hand that had a long slender prod's on it.The wire's were attached to a small black box that rested on marks back.Every once in awhile the man would touch the prod's to Marks nipples and he would throw his head back as his eyes flew wide open. My eyes were glued to those prods as he held them longer against Marks nipples.I saw his dick jerk up high just before wads of white creamy cum shot two feet out in front of him. It was then that my mom took my hand and led me to the bath room where we showeredthen put our clothes back on.I was to have those prods on my mind for days to come. It was a couple of weks later that I first noticed grandpa talking to Stevie,the boy nexy door,it wasn't long before the two became really good friends. I knew it would not be long till grandpa would have the boy naked,I entended to make sure I was around when that took place....
