My brothers and I stood with our hard, throbbing cocks in our hands as our father scribbled on three small slips of paper and placed them in a bowl. My brother Gary drew one of the slips and grinned when he saw the word "mouth" written on it. My brother Roy drew next and got the word "pussy". Two of Mom's orifices had been taken and only one was left. Even though I already knew what was written on it, I drew the final slip of paper and read aloud the word "ass".
Our beautiful mother Gloria was sprawled naked on the bed impatiently fondling her full bush as she waited for us to make her Mother's Day a very happy one. Dad began videotaping as Roy went to his back next to her. Mom bent down and sucked his big cock for a minute or two just for good measure, then she straddled him and slowly impaled herself on it. Dad, Gary and I bent forward to watch the penetration. What a sight it was! Mom's slack labia tightened up as Roy's thick cock pushed them aside. They were soon stretched like rubber bands around the fat prick. The penetration alone was enough to start her huffing and puffing. When all of us got in the act, Dad would have to close the windows and turn on the air conditioning to muffle Mom's exuberant shrieks.
The ass-man always comes first, so I gave Roy a head start to increase the chances of everyone coming together. After carefully oiling my cock, I knelt next to Mom on the bed, pulled her cheek to the side, and squirted a thick bead of lotion across her wrinkled anus. I smeared it around, then gently worked a finger up her ass. The tight little hole responded to the invasion by clamping down. I continued sawing my finger in and out until the clenching slowed and weakened. I added a second finger and then a third to prepare her for the final assault. As I eased my cock into her tight hole, Gary was at the other end sliding his between her lips. I pressed down on the small of her back to hold her in place and placed the tip of my cock against her anus. I felt a sense of detachment as I watched the head slowly disappear into her body. It was as though I were watching someone else's cock. I sank my cock in all the way to the balls.
With the camera in his right hand and his cock in his left, Dad circled us in search of interesting camera angles. He would get his turn in the cluster when he replaced the first of his sons to come, but he wasn't in any hurry. The ass-man usually finishes first, but I felt in pretty good control and hoped to make this time an exception. Mom was working her hips back and forth between Roy and I. When she thrust forward onto Roy, her ass clamped down on my cock. We soon had a nice rhythm going with Roy and I driving our cocks into her on alternate strokes. My balls slapped against his with each thrust. I felt the heat radiating from his feverish cock-head through the thin membrane separating the two orifices.
I reached beneath her to feel her tits and found Roy nursing on one. I gave the other one some attention. The nipple was wet and swollen from Roy's sucking. Mom's moans grew louder and filled the room. She would have been much more vocal if Gary's thick cock had not been serving as a gag. His eyes rolled back in his head and his teeth clattered as he shot his load in her mouth. I heard her choke and then watched her cheeks puff out as Gary filled her mouth with his syrup. Mom held the load in her mouth as Dad stepped forward for sloppy seconds. She kept her lips tight around his cock to avoid spilling any of the precious fluid. Dad's eyes lit up as his cock basted in a mixture of Mom's spit and Gary's spunk. Gary took over on the camera and stepped up on the bed to get some shots that Dad hadn't gotten around to.
I managed to play my part long enough for Mom to have a strong orgasm. The tight tunnel sucking at my cock finally got the best of me, and I shot my load deep inside her. I was shaking like a leaf as I dismounted and rolled out of the way. I felt a little nauseous just as I always do after fucking my mother. Dad winked at me as he took my place in her ass. He chose to synchronize his thrusts with Roy's thrusts. The look on his face was the same look my dog gets when I scratch his funny spot. Mom always goes wild when the thrusts are synchronized. With no cock filling her mouth, she wound up like an air siren until Dad clamped his hand over her mouth. Father and son groaned in unison as they shot their loads. It was a picture-perfect ending with mother, father and son coming together.
Perhaps you are wondering how my family forged our forbidden relationship. First let me describe my mother. She's a tall, statuesque beauty with long legs and a winning smile, all qualities that are essential for success as a haute couture model. She strutted down many runways showing off the work of some of the biggest names in the business. Then Dad swept her off her feet and she gave up the world of glamour for a life as a housewife. As far as I know, she never doubted her decision.
