Mom walked in and went to the far side of the room. I panned across back to the door just as Grandad walked in. I had seen photos of him but I hadn't really expected him to look as old as he did now. But I guessed he must be pushing sixty five. The other man came out of the shadows on the landing into the room encouraged by Grandad. When I saw him, I realised just how much Grandad hated my Mom. He must have been about six two or three, skinny as a rake, wearing a tattered old overcoat and torn trousers with no socks and a pair of battered old jogging shoes and was so grimy that it was hard to tell the colour of his skin. Not that there was that much on show. He had a long, tangled dirty beard and moustache, yet was almost bald. 'You'll have to forgive the appearance of my friend here, Barbara. You don't get much chance to bathe living out on the streets. But he'll make up for it with his keeness for you. You see, he's like me, he hasn't had a woman for years either.'
Grandad turned to the hobo and said, 'Go git her boy, she's all yours' The man stepped slowly towards Mom. I panned the camera to get them both in shot and made sure the tape was rolling. Mom moved back but eventually was blocked by the wall. As the dirty tramp got closer, he took off his overcoat and threw it on the floor. That was followed by his shirt, revealing a dirty, grime covered torso underneath. From out of shot I heard Grandad tell Mom that she should show her guest some more hospitality and ordered her to take off her robe. Mom had little choice but to obey. The vagrant stood still and licked his lips as Mom undid the tie that held her robe together. It parted at the front, and I saw the tramp start to rub the bulge in his soiled trousers. Then it was off, and Mom stood naked in front of them wearing only her hold ups and heels. The tramp's mouth parted, revealing six or seven blackened, rotten teeth.
He lunged at Mom. She cringed as his mouth found hers and with her head in a vice made from his hands, she twisted in vain to escape his fat, slobbering lips. My dick was hard as rock as I watched this human excrement ravish my own Mom. He moved his hands all over her breasts, before picking her up and throwing her on the bed. He stood over her as she lay helpless, and undid the piece of string that he used as a belt. His trousers fell around his ankles revealing his long, thin erection. Mom closed her eyes as he took hold of her high heeled shoes and spread her legs wide. He positioned his dick at the entrance to her pussy and stabbed it into her. Mom gasped as his first thrust filled her up. The hobo fell on top of her and as he pumped furiously at Mom's snatch, the contrast between her clean white skin and his sweaty, grimy body made me almost cum in my pants. His long fingernails dug into her boobs and he tweaked her nipples until she cried. Then he bent his head down to her face and began to slobber all over her again. His ass moved quickly up and down as his dick, piston like, continued its glistening travels in and out of my Mom's love box.
Suddenly, Grandad appeared in shot, with his dick also in a state of high arousal. He climbed on to the bed next to Mom's face and told the vagrant to give him some room. Grandad lifted Mom's head onto his knees and twisted it so that she faced him. 'Suck me off, Daughter', he commanded. Mom opened her mouth and her Father slipped his meat inside. Keeping his body still, Grandad took hold of the sides of Mom's head and moved it to and fro along his shaft. Her face was now turned away from the camera, but small things indicated to me that she was beginning to enjoy this; the way she began to clench the bed sheet with her fist, her hips moving to meet the vagrant's incoming thrusts, and the soft groans that came from her throat as Grandad fucked her mouth, all gave her away.
I couldn't stand it any longer and I took my dick out and began to pull myself off. Mom was covered in a glistening sheen of perspiration now. And because of this, some of the grime had transferred itself from the hobo's skin onto hers. She looked as filthy as he did. And I could see the dirt on Mom's body wherever his hands had touched her. Eventually, the hobo's face became contorted and I knew he was near to emptying his load. His nails had made runs in Mom's hold ups as his body reached a climax. With a roar he pulled out of Mom and quickly moved up to straddle her breasts. He pulled quickly at his throbbing penis and at last he shot pints of hot, white muck over Mom's face and hair. Her left hand went to the tramp's balls and she gave them a good squeeze and I knew for certain that she was now enjoying her role as her Father's sex slave. Seeing the hobo cum over Mom had the same effect on both my Grandad and me. But where he got to empty himself down Mom's inviting throat, my load went over the table that the TV was resting upon.
Both men stood up to get dressed, leaving Mom lying shagged out on the bed. Grandad had made certain that any of the vagrant's juices still covering Mom's face was scooped up and put into her mouth. As he left, he assured Mom that in two weeks' time it would just be him and her, and that he would make sure that the hobo didn't know where she lived by blindfolding him on the way back as he had done on the way in.
I heard them close the front door and Mom dragged herself into her bathroom. That gave me the opportunity to get out of the house and to return after eleven as expected. Mom wasn't up when I returned and the lights were out in her room so I assumed she had gone to sleep. I knew that I could retrieve the camera the next day and no one would be the wiser.
A couple of days passed and I had finally worked up the courage to approach Mom with my offer. Dad was still on his day shift, and Mom and I were alone. With my heart in my mouth, I heard myself tell Mom that I had a great new video that I thought she would like. She told me to get it and play it downstairs. I was trembling as I placed it in the VCR and pressed 'PLAY'. If you've ever passed a TV store in the street that has had a camera pointing out at the passers by, you'll know the delay when, at first, you don't recognise yourself on screen in their window. That is how it hit Mom. She knew the room in the video, but for a second or two she didn't know where she knew it from. It all became crystal clear as she saw herself enter, followed by Grandad and then the tramp.
Her mouth dropped open as I let the story play out. I wondered how she would react. At last, Mom turned to me and said: 'I suppose this means that I am to be your sex slave as well?' I looked at her and just nodded. She said that there can't be too many women who have been fucked by their Father and their Son. She asked what the terms were to be. I explained that, like Grandad, I'd want to have her on the week when Dad was on his night shift. I also mentioned that I had two copies of the tape, in case she was thinking of getting smart. Mom said there would be no need for any nastiness as she was quite looking forward to some young meat for a change. Encouraged by her reaction, I asked if we might go fuck now. 'It's too risky, your Dad will be home any time now', she began, 'but I could give you a quick blow job in your room, if you like'. Mom took me by the hand and led me upstairs. As we walked, she said that what she'd really like is if I took her out on a proper date. She said that she'd be certain to give me lots of attention and flirting. With my dick getting ever harder I suggested that next Friday might be a good night and we made it a date.
Mom pulled me into my room and left the door ajar so that we could hear Dad come in. She knelt in front of me and undid my trouser zipper. It felt like I was in a dream; I was actually going to be blown by my own Mom, just like I had fantasised. I looked down at her below me. Mom was having trouble getting the zip over my bulge so I kind of breathed in to make it easier for her. At last my pants were undone and, using both hands, Mom pulled the top of my shorts down thus freeing my hard on. I think she was impressed. 'My, my', she exclaimed, ' you have grown bigger since I last saw your little man. I know I'm going to like this' I still think about that first touch of my Mom's hands on my most private organ. Surely, this is what every boy dreams of at least once in his life, if he's honest.
Coyly, Mom looked up at me through half closed eyes as her hands pulled back the foreskin of my prick. It was already wet, and as she moved the tip of my knob around her face, it left a trail like a snail. She flicked her tongue into my slit and I felt my knees begin to buckle. Mom then opened her mouth wide and, still with her gaze holding mine, slowly enveloped my dick. Her mouth was succulent as it went about its business of bringing me to ecstasy. Mom's head began to move quicker back and forth and her right hand was at the base of my dick, gently wanking me. She twisted her head so that every time my dick thrust in, it made her left cheek bulge outwards. This, and the combination of her seductive stare, finally sent me to heaven. Mom sensed I was cumming and started to pull me faster. I exploded into the warmth of her mouth just as Dad came in through the front door and asked if there was anyone home. I could hardly breathe, let alone speak, and as Mom stood up in front of me and shouted that she'd be right down, I could see the final traces of my semen in her mouth before she swallowed. With a final wipe around her lips, she let go of my dick and gave me a smile and told me she was looking forward to our date.
I had to take the camera back to college, so I didn't know how Mom got on with Grandad when he came around the following Wednesday, and I didn't ask. I came home around four on the Friday and Dad was still at home. I told him I had to get to the bathroom to get ready as I had a hot date that night. As he left for work, Dad shouted up that I should give the lucky girl one for him. Oh, I'd do that alright I thought. Mom had asked me to wear a suit, and she was at home when I got dressed and went downstairs.
