The next morning, Jeff was the first to wake up. He looked over at his naked sister Amy, who was asleep beside him. A single sheet only covered her stomach. She was lying on her back, and he could see the triangle of her well-trimmed pussy. Her tits were getting bigger, he thought. She had put on a couple of pounds in the three weeks since he's seen her last. In fact, since he started fucking her a few months ago, she had probably gone from an overly skinny 110-pound 18-year-old, to a nice figured 130-pound 19-year-old. He was hard. He wanted to fuck her again. He decided that he should go to the bathroom first, and let her sleep a little longer. He turned his head and looked at his other naked sister, Bonnie. She was about the same weight, yet it didn't go to her tits. She too was sleeping, half under the same comforter that he was under. He quietly slipped out from between his two sisters, his naked cock sticking partway up in the air. He went out the door and down the hall to the washroom and took a leak.
His movement roused both sisters. Amy lifted her head and watched her naked brother disappear out the door. She stretched her naked body, jutting her (noticeably bigger) tits out, and looked over at Bonnie. Her pussy was tingling. Ever since her brother introduced her to orgasms, she had been waking up this way every day.
"Do you wanna surprise him?" She asked.
"Sure!" Bonnie replied. "Let's get him in the shower. I have a feeling it's gonna be a fun day!" The two nude siblings got out of bed and rushed up the stairs, Bonnie leading the way. Amy looked at her skinny ass as it bounced up the stairs. She wouldn't mind some of that, as well!
Jeff flushed the toilet, and was standing naked before the mirror when the door opened and his two lovely sisters walked in. His dick had never risen so quickly. It was fully erect in a microsecond. Amy had a big smile on her face as she hugged him and gave him a soft peck on the mouth.
"Good morning!" She said, excitedly. "Time for a shower!" With that, she pulled away from him and turned around, bending over to turn on the tap in the bathtub. He barely had time to admire one sister's naked ass as she bent over in front of him, when another sister's arms were around his neck.
"Good morning!" Bonnie smiled, kissing him firmly on the mouth. His hands slid down to the naked cheeks of her bum, and squeezed them lovingly as he heard Amy turn the water on. Her smooth, soft cheeks were cold in his hands, and he gave them another squeeze as he kissed her back. She could feel his hardness pressed against her belly, and she thought that he was getting even bigger and harder as they kissed.
He broke the kiss when he felt Amy grab his arm. The shower was running, and he had two beautiful, naked sisters that wanted him to join them in it. Once in the shower, his sisters were all over him. Amy soaped up her hands and began to rub the lather all over his arm, chest, and down his stomach. Her young hand gripped his hard-on. Bonnie took the soap from her and began to lather up the other side of his body as she softly kissed his cheek. Jeff was in heaven. He ran his hands down their smooth, wet, naked bodies until he grabbed Bonnie's ass cheek in one hand, and Amy's ass cheek in the other. He pulled both his sisters close to him, pressing them tightly against him as they kissed and soaped him all over. Both their hands were on his cock, stroking it. Sometimes one would play with his balls, he couldn't keep track of who was doing what! He turned his head to the right, and his mouth was on Amy's, tongue darting out. She pressed her crotch against his leg, as they tongue-kissed. He broke the kiss and turned to his left, where Bonnie's lips were immediately on his. She wrapped both arms around his neck and pulled herself to him, kissing him passionately. His hand grabbed Bonnie's smooth, wet ass as he kissed her.
Amy, meanwhile, was staring at her brother's dick that was standing straight up in the air.
Her horny little pussy was tingling like crazy at the thought of having such a thick, hard tool sliding into her. Breathing laboriously, she sunk to her knees in front of him, at a bit of an angle because there was not a lot of room.
She bent him downwards and immediately slipped her lips around his taut pole. Jeff sighed into Bonnie's mouth at the sensation of a warm mouth around his manhood.
He broke the kiss, taking the soap from Bonnie's hand. She stepped back in the shower, soaking her hair as he lathered the soap in his hands. Amy was sliding her lips up and down his cock, expertly, slurping loudly. He looked down for a moment at the way his baby sister's lips were wrapped tightly around his meat, making it disappear over and over. She pulled him out of her mouth, looking up at him with her dark eyes as she tilted her head underneath him. Her tongue snaked out and lightly lapped at his balls. Her hand held his organ straight up in the air as she sucked a testicle into her mouth.
He reached forward and began to rub soap all over Bonnie's chest, lathering all over her small, soft breasts. Her nipples were erect, and her brother's hands rubbing all over them did not make them any less so. He could feel Amy's tongue slowly lick up his shaft as his hand cupped Bonnie's pussy. He felt warmth engulf his cock, and he knew he was inside Amy's mouth again.
Bonnie pressed her soapy body against him, and he brought his hands around to her ass, rubbing soap all over it. Her lips searched for his, and he kissed her, rubbing the bar of soap down the crack of her bum. He shot his tongue into her mouth as he moved his other hand into her crack. He ran his fingers right along her crack, feeling the puckered little hole of her ass. He dipped the tip of his finger into his sister's asshole, and Bonnie moaned softly in his mouth, tingles firing up her body. He pulled his hand away, and she bent over a little, allowing the spray of the shower to rinse the soap off her back and ass, breaking the kiss in the process. Bonnie turned around to rinse off the front of her body, and Jeff's cock twitched in Amy's mouth at the sight of her skinny, creamy white, wet, naked ass.
Bonnie turned back to him, and fell to her knees beside her sister. He looked down, watching Amy's lips slide up and down his cock rapidly, slurping loudly. Bonnie grabbed the base of her brother's penis, and Amy allowed her to slip it out of her mouth. Bonnie pointed his hardness in her own direction, and eagerly slipped it into her mouth. Jeff loved the look of her pretty, freckled face as he fed it his dick.
He reached down and pulled it out of her mouth. He had a sister on her knees on either side of him. Bonnie's back was to the spray, and Amy was facing it, but both of them were leaning in front of him, faces mere inches from his organ.
