The words they used inflamed Bill's mind even more, as Susan knew they would. She kept telling him to fuck his sister in her wet cunt with his cock, over and over, telling him to come in her, to fill her hungry cunt with his come juice. She pulled at his balls tenderly, twisting them, staring at his cock as it penetrated the hairy lips of her daughter's so eager cunt. She saw Tracy's asshole drawing inward, then pooching. It was obvious to Susan that her daughter was coming before Tracy even started screaming in ecstasy. Her own cunt was quivering, and Susan knew that she would come just by watching. She leaned closer, turning loose of her son's balls, wanting to watch them writhe as he came, as his cock squirted sweet come into his sister's greedy cunt.
Bill, with his sister's cunt squeezing hard on, his cock, rammed into her, holding his body stiff. He made a growling sound, then his cock erupted with a spurting flow of come juice. The sensation, of her brother squirting into her bubbling cunt creaked a final, more powerful orgasm inside Tracy's cunt. Her naked ass shot hard against him, grinding as she screeched her pleasure, the hair-rimmed lips of her cunt visibly clutching his cock.
Susan saw it all, saw her son's balls draw up and writhe as he came, saw her daughter's cunt grip him with squeezing tightness. There was nothing she wanted more in the world at that moment than to pull her son's cock from her daughter's cunt and start sucking greedily at the flow of his spurting thick jism. Her cunt was twitching with orgasm, her clit intensely distended. She placed her hands on her son's naked and trembling ass, trying to push his discharging cock deeper into Tracy's cunt. Then, unable to keep watching, she smashed her lips to her son's ass, kissing with open lips, sucking and licking at the smooth freshness of his ass, still coming. She moaned loudly, almost as loud as the screeches of her daughter. Impulsively, Susan slipped her tongue across her son's ass and did something that she had never done before; she shot her long tongue into the crack of his ass, probing against his asshole.
With a yelp of surprise, Bill jerked, his cock slipping out of Tracy's cunt. He flopped to the floor, looking at his mother in surprise.
CHAPTER SIX
Bill had lost his shyness.
With a sister and mother that seemed to want his cock constantly, there was no reason to be shy. He looked at them openly without blushing, and enjoyed it when they looked at him now. He was not embarrassed when his cock became hard, which it seemed to do all the time.
He had sat on the floor looking at his mother in surprise when she darted her tongue against his asshole, but realized that was what she wanted to do. It had not been accidental.
His face spread in a grin.
"You better be careful doing something like that, Mother," he said bluntly, his eyes glowing.
"Why honey?" she asked, sitting on her heels, her skirt halfway up her slim thighs. Tracy's ass was back an the floor, but her legs were wide and her tits heaving.
"What happened?" Tracy asked.
"Mother licked my asshole," Bill giggled without the faintest sign of shyness.
"What's wrong with that?" Susan asked. She glanced at her daughter's cunt. Her pink pussylips were wet, and come juice was seeping from them and over the rounded curves of her ass to the floor.
"I might… I could have, you know, shit," Bill giggled, finding delight in talking this way. He used such words with his friends, but this was the first time with his mother and sister.
Susan smiled wickedly. "So what?"
Bill's eyes widened. "Ahhhhh, you'd probably like it if I did."
"Maybe," Susan said. "Maybe I would."
"That's right," Tracy giggled, caressing her naked tits. "You never know until you try it. Right now, though," she said getting up and cupping her hand between her dripping thighs and holding her cunt, "I have to piss, and I don't want to mess up the carpets."
A shiver of unexpected pleasure rippled through Susan as she looked at Tracy. "I think I'll go along and watch you."
"Then you better hurry, Mother," Tracy said, going to the bathroom quickly.
Susan got to her feet, reaching to pull her son up. "Let's watch, Bill," she said, her voice strangely husky, "Let's, go watch your sister piss."
Holding his hand, she pulled him along with her. They reached the bathroom just as Tracy was starting to sit down. She held her short skirt about her small waist, her cunt gleaming wetly.
"That way," Susan said. "Don't sit down, Tracy. We won't be able to watch if you sit on the toilet."
Tracy spread her legs around the bowl, stepping back so that she would be sure to piss into it. Her ass touched the cold water tank, and she giggled.
"Well," Susan said, squatting in front of her daughter, her eyes bright with perverse anticipation. "Go ahead and piss, honey."
She clung to her son's cock now as he dropped to his knees so he could see, too. Like his mother, his eyes, were glowing with eager pleasure, straining on his sister's cunt. Tracy's pink cuntlips could be seen, as could the tip of her clit.
"I don't know if I can piss standing up," she said. "I've never tried before, nor with anyone watching."
"You can do it, Tracy," Susan urged, running her hand up her daughter's thigh and holding her hip. "You can piss, baby. Strain a little. Come on, Tracy, piss for us!"
Excitement filled Susan like never before. Wanting to see Tracy piss was a strong, erotic desire within her, something she had not considered before. Her gaze riveted upon her daughter's cunt, waiting to see the golden stream flow. She clutched her son's cock tightly, gripping Tracy's hip with her other hand.
A spurt of piss came from Tracy's cunt.
"Ooooh, there it is!" Susan moaned, feeling a rippling stab of unusual ecstasy flood her body.
A second spurt came out, and Susan gulped, running her tongue over her lips. Bill, his cock starting to become hard as he watched his sister's cunt, found himself as excited as his mother to see Tracy's piss. Tracy, too, felt a strange pleasure in having them watch her, and she began to piss, making it tinkle into the water of the toilet. As she kept pining, the stream became stronger, arching out until it splashed on the rim of the toilet set.
Susan's eyes glowed hotly and she jerked on her son's swelling cock. "That makes your cock hard, Bill," she hissed to her son, but she kept watching her daughter's cunt and the stream of golden piss. "That's what will make your cock hard, baby! Piss, Tracy… Ooooh, keep pissing. That's a beautiful sight! Ooooh, I love seeing you piss! Don't you like it, too, Billy?"
Bill was too absorbed in seeing his sister piss to answer. His cock was now in full hardness as his mother jacked him with a tight, hot fist. The golden stream of his sister's piss excited him, and he could see where it came from. He moved a hand to her hip, then around to hold one cheek of her lovely tight ass.
Susan, pumping with excitement on her son's throbbing cock, brought her hand from Tracy's hip and moved it into the stream, cupping her palm. Tracy, looking down, as she held her short skirt at her small waist, giggled to see the piss flow from her mother's hand.
Tracy's piss felt warm and exciting in her palm, and Susan's cunt began to burn again. Her fist beat frantically on Bill's cock. Bill clutched at his sister's ass while gazing with more excitement than he thought possible. He had seen many teens pissing, but that had done nothing for him. But seeing his sister pissing was making him so hot, he wondered if his mother's jacking fist would make him come off.
Then Susan couldn't help what she did next. To the amazement of her son and daughter, Susan shoved her long tongue way out, and slipped it into the stream of piss. Piss splashed on the tip of her tongue, and tasting it made Susan moan, her eyes dosing as a fantastic shiver of ecstasy went front her head to her toes.
