I suspected that my brother John was more than just a father to nineteen year-old Sophie. The inordinate amount of time they spent together included long horseback rides in the afternoons. When they returned, Sophie always had the look of a freshly-fucked woman. She was home from college on her summer break. The gangling tomboy had blossomed into a strikingly beautiful woman. I could hardly blame John for lavishing attention on her. "If he is drilling her, more power to him," I thought.
John and I and our wives Flora and Molly lived together in the mansion that John and I inherited from our father. We had also inherited enough money to permit us to live a life of leisure. With so much time and energy on our hands, it isn't surprising that sex became a favorite pastime. John and I regularly fucked each other's wives in the same bed. In addition to inheriting wealth, we had inherited something perhaps even more important - long, thick cocks. Our ten-inch fuckers induced many an orgasmic scream from our over-sexed wives.
One afternoon I watched from my second floor bedroom as Sophie sunned herself beside the pool. Thinking no one was around, she removed her bikini top to expose her two flawless tits to the warm rays of the sun. Naked except for a tiny triangle of cloth covering her cunt, she slipped her fingers beneath it and began to masturbate. I immediately filled my hand with cock and began to stroke.
My wife Flora walked in and saw what I was doing. "Come and use your hand on me," I said. Flora giggled when she saw what I was looking at. "You want me to jack you off while you're ogling your own niece?" she asked. "Sure, why not? Kneel down next to me and give me a hand job." Flora spit in her hand and began to stroke my rigid rod. I watched as Sophie's hand moved more rapidly inside the tiny patch of cloth. She pushed it aside to reveal a shaved cunt. "My God, she's jacking off," Flora said. "Watching her is making me hot. Don't waste your load on a hand job. Fuck me instead."
I fucked Flora's tight pussy doggy-style as we watched Sophie trying to finger herself to an orgasm. "I think she's going to make it," Flora whispered. "I'm almost there myself." I clamped a hand over her mouth lest her moans alert the girl. Sophie stiffened and her legs snapped shut. She grimaced as an orgasm rippled through her like an earthquake with its epicenter at her clit. As Flora's orgasmic contractions squeezed my cock it shot off gobs of cum. Sophie rearranged her bikini and dove into the pool. As I watched her swim, I decided to spy on her and her father until I found out what they were up to.
I waited by the stable hoping that John and Sophie would take one of their late afternoon rides. I was pleased to see them enter the stable. A few minutes later they came out leading their saddled horses. As they rode off, I followed behind on a bicycle. I couldn't risk following on horseback; if they had seen my horse missing from his stall, they might have canceled their ride for fear of being caught.
I followed at a safe distance until they stopped at a pastoral spot beside a babbling brook. After tying the reins to a branch, they began removing their clothing and hanging it on the pommels of the saddles. I brought my binoculars to my eyes to get a closer look. John's enormous cock arched out from his belly. Sophie took it and his balls in both hands and fondled them. Judging by the broad smile on her face, she was under no duress. Under his daughter's skillful touch, John's cock hardened rapidly.
Sophie went to her knees and took the fat bulb of her father's cock in her mouth. He grinned down at her and caressed her long, golden hair. She struggled to get all of it in her mouth but could manage only the head and an inch or two of shaft. After sucking for awhile, she took it out of her mouth, wrapped her hand tightly around the shaft, and began to jerk. As John let out an anguished groan, his cock began spewing all over his daughter's nubile tits. She watched with an impish smile on her face as the very seed that had spawned her gushed against her nipples. When he was finished, John fell to his knees as Sophie rose to her feet. He licked every drop of semen from his daughter's body. I wasn't surprised. When we fucked each other's wives, he always ate his cum and frequently ate mine.
As John lapped up his cum, he masturbated to keep his erection. Sophie went to all fours and stuck her ass up. John took aim at her hairless pussy. Both had broad smiles on their faces as they mated. At that point, I took my own hard cock in hand and stroked it. The incestuous lovers were in profile to me so I was able to get a good look at the penetration. For someone so young, Sophie was able to take a surprising amount of her father's thick prick. More than half of it sank into her with each thrust.
The pretty smile disappeared from Sophie's flushed face and was replaced with a frown. Beads of sweat popped out on her furrowed brow. She gritted her teeth and screwed her eyes shut. Even though I was a considerable distance away, I heard her shout, "OH, DADDY, FUCK ME HARD, I'M CUMMING!" That brought a smile to my brother's ruddy face. He made her cum twice more before he yanked his tool out and sprayed her ass. At that instant, I shot my dick juice onto the ground. After John licked her ass clean, they dressed, mounted their horses, and rode back toward the mansion.
