On her knees, she looked at her brother, seeing that he was tired. She looked at her mother and saw the same expression. She would either have to fingerfuck herself or… her gaze rested on her mother's tits, the woman's nipples still hard and arching up. Quickly she straddled her mother's chest, holding one tit to make the nipple stand tall. With mewling sounds, Tracy pressed her mother's tit between the lips of her cunt, but it would not go deep enough. She settled for rubbing her mother's nipple about her swollen clit.
Susan felt her daughter rubbing her hot, wet cunt about her tit, and still panting, caressed her sweet ass and let Tracy do what she wanted. She was very familiar with the frustration of needing to conic and had no way except her own fingers. If Tracy wanted to come by rubbing her sugary cunt on her tits, then Susan didn't mind at all.
Tracy was sitting on her mother's tits with her face toward Susan's feet. There was a large window on the far wall, and the drapes had not been pulled. It was now dark, but they had every light on in the bedroom. At first Tracy wasn't sure, but looking again she saw the face of the neighbor peering in at them. The window was closed, and their voices did not carry through it, but Tracy whispered anyway.
"We're being watched," she said, not stopping her hips. "The neighbor is watching through the window, Mother."
Bill's head jerked up, but before he could swivel around to look, Tracy stopped him. "Let him watch, Bill. Don't let him know we see him. It makes it better for me."
From behind Tracy's squirming ass, Susan agreed. "Yes, let him see us."
She spread her legs as wide as she could, knowing the neighbor could see her hairy cunt this way. He had wanted to see her cunt since she started sucking him off, but Susan had always turned the guy down. Now it excited her to be seen with her son and daughter, fucking so wildly. Her cunt began to pulsate hotly again as she worked her hands between Tracy's legs. She molded her tit and said: "Try to take my tit in your cunt, baby."
Tracy pulled the lips of her cunt wide, and Susan managed to get her hard nipple and part of her tit into Tracy's pussy.
"Now fuck my tit, honey," Susan said.
Bill was watching his mother and sister. He wasn't at all interested in the neighbor. He didn't care if the guy watched or not. If being seen excited his mother and sister, then it was fine with him. He stood up on the bed, offer ing his cock to his sister's mouth. "Lick me, Tracy," he said. "Lick my cock."
Tracy looked at her brother's cock, seeing it glisten with the wetness of their mother's cunt, his balls sweet as they dangled below. Squirming her cunt on her mother's tit, fucking on it, but mostly rubbing her wet pussyslit and her swollen clit against it, Tracy shoved her face into her brother's crotch, her lips wide. Tracy tasted her mother's cunt juices and the lingering jism. She lapped at his cock and balls, still holding her cunt wide open with both hands. Bill held his sister's head and started grinding his cock and balls against her face. Susan could watch, too, and she began to writhe and twist her naked ass on the bed, opening and closing her long legs. She could almost feel the neighbor's eyes on her cunt, and the thought created a steamy heat there.
Tracy widened her lips, opening her mouth as wide as she could. Bill giggled as his sister drew not only his wet cock into her mouth, but his balls as well. Tracy moaned softly, excited to have her brother's balls and cock in hr mouth at the same time. She whipped her cunt faster on her mother's tit, sucking hard on Bill's cock and balls. If Bill's cock started hardening in her mouth, she would have to turn one of them loose, but in the meantime she sucked and licked them both.
"I bet his cock is hard as a fucking rock," Susan laughed behind Tracy's squirming ass, "I bet he has it out and is jacking off like crazy, seeing us doing this."
She lifted her head and began to lick hotly at her daughter's ass, dragging her tongue along the deep, exciting crack while Tracy kept rubbing her cunt back and forth on her nipple. Tracy's head was turned sideways to suck on Bill, and she could look up and watch.
Bill had released his sister's head, and was squeezing at her firm tits with both hands now, leaning over slightly. His cock was hardening inside his sister's wet mouth. Tracy, feeling his prick become hard, had to let his balls go. But she gulped his prick quickly back into her mouth and began to suck with vigorous motions, her hair dancing. Occasionally, Susan's tongue reached her daughter's asshole, and she lapped against it until Tracy's hips jerked forward. Smearing her cunt this way on her mother's tit, cunt juices smeared the girl's puckered asshole. Susan could lick it up, taste her daughter's cunt and asshole at the same time.
Tracy's hot mouth, gobbling at his cock, made Bill's prick very hard again. It throbbed between her gliding lips. When Bill began to fuck her in the mouth, Tracy held her head still. But that wasn't satisfying enough to her. She began to thrust her mouth onto his cock as he plunged forward, then draw back with her lips as tight as she could make than as Bill prepared another thrust.
Susan moaned hotly into her daughter's ass, still scissoring her long legs. She was not holding her tit now, but was gripping Tracy's hips, pulling her ass backwards, making her daughter squirm her cunt into her mouth. Susan's tongue delved hungrily, tasting and swirling into her daughter's cunt, her nose pressing into the girl's puckered asshole.
Tracy rubbed her crotch about, smearing her mother's face with the seeping fluids, rubbing her cunt into Susan's mouth, then pressing her asshole against it. She sucked with a greedy hunger on her brother's cock, holding his hips and making him fuck hard into her mouth.
Bill was groaning again, fucking his sister's mouth swiftly in short, quick strokes. Tracy sucked powerfully, her tongue swirling about the throbbing heat, tasting his pre-cum dripping onto her tongue. She felt her mother's lips sucking at her asshole, trying to thrust her tongue into it. Tracy relaxed her asshole and squealed about her brother's cock when Susan's tongue stabbed into her ass. The spasms began in Tracy's cunt, the orgasms making her sweet, naked body shake in a violent way. As she came, her asshole seemed to suck on her mother's tongue, and she began sucking as hard as she could on Bill's cock.
Bill was very excited, and he plunged swiftly. His cock suddenly pulled from his sister's mouth just as he came. The bubbling, creamy come juice spurted from his piss-hole and splashed onto her face. Tracy opened her mouth wide, catching some of it with her tongue, but most flew against her face and even into her hair.
Susan, feeling her daughter's asshole spasm around her plunging tongue, erupted into an orgasm that sent her hips arching into the air.
Finished, Tracy sat on her mother's face, her head hanging down, come juice dripping down onto her tits and nipples, and onto her mother's tits. Bill sat down, and now he could not resist looking toward the window. He saw the wide-eyed neighbor clearly, and then the face was gone.
"He ran away," he panted. "He saw me looking at him and took off."
"I bet he was jerking off," Tracy giggled. "I know I would if I saw what we did."
"Let's go see," Susan said, swinging her legs over the bed. She started to take her robe from the closet, then said, "Fuck it; it's dark outside."
Feeling delightfully wicked, all three went out naked into the back yard. Bill carried a flashlight, but had not turned it on yet. They went to the bedroom window, and when he switched the light on, they saw come juice gleaming against the wooden wall of the house.
"He came off!" Tracy whispered. "He came off on the house."
Susan dropped to her knees on the grass, and to Tracy's and Bill's astonishment, began to lick at the warm come juice with her long tongue, moaning with perverse pleasure.
