Chapter 4

Kathy woke up Sunday morning and glanced across the room at her little sister Mandy, who was still sound asleep. Kathy got out of bed, went out of her room and down the hall to the bathroom. After she was finished, she started downstairs, but decided to look in on her brother.

Mike was lying on his back with the covers kicked off his body. Kathy looked down at his crotch and noticed his penis was erect and poking out of the fly of the boxers he wore to sleep in. Slowly, she slipped into his room, moved next to the bed and stared down at her sleeping brother. As she watched him sleep, she put her hand between her legs and began to rub herself, noting she was a little tender from the night before.

Kathy thought about the experiences of the previous day and began to grin. Moving as carefully as she could, she leaned over and touched Mike's erection with the tip of her tongue. When his penis jumped, she pulled back slightly and looked at his face to be sure he was still sleeping. Once she was confident she hadn't wakened him, she again licked his member. Getting braver, she took the bulbous head between her lips and coated the end with her saliva. She took a couple of inches of his hard shaft into her mouth and then pulled back until only the head was against her lips.

Mike let out a groan as his sister lowered her mouth again and rubbed the underside with her tongue. Glancing up, Kathy saw her brother open his eyes and look down at the source of the pleasure. When she winked at him, he grinned and lowered his head back to the pillow. Kathy climbed onto his bed, moved between his legs and began to move her mouth over the length of his rigid shaft.

Rising up on his elbows, he stared down at his sister, watching her bob her mouth on his cock. From his angle Mike could gaze into Kathy's gaping pajama top and see her firm breasts.

"If you keep that up I'm going to cum, Kathy," Mike warned.

"Mmmm," Kathy moaned around his cock as she began to increase the speed of her head. She moved her lips further down on him. Kathy reached between his legs, cupped his testicles, and gently rolled the orbs in the palm of her hand.

Mike started to push up into her mouth and groan. Kathy felt his cock swell in her mouth and his hot cum splatter against the roof of her mouth. She swallowed as fast as she could as jet after jet of semen surged through her brother's cock and into her sucking mouth. When Mike's ejaculation reduced to a dribble, Kathy held him in her mouth and stroked him with her tongue.

Lifting her head, Mike's still firm penis pulled free of her lips with a "pop." She wrapped her fingers around his slick member and stroked it as she smiled at him.

"Good morning," Kathy giggled as she licked her lips.

"Wow, Sis! That was great. What made you do it?" Mike said.

"Do what?"

"Suck my cock, silly, what do you think?"

"Oh I don't know, Mike. I just stopped in here to see if you were up yet and when I saw your hard cock I just couldn't resist. You didn't mind did you?" Kathy said and then she giggled.

"Hell no!" Mike said, sitting up and reaching for his sister. "You can wake me up like that anytime you want to."

Mike pulled Kathy next to him and slipped his hand under her pajama top. He covered one of her breasts and massaged it, flicking at her nipple with his fingertip. He felt the small nipple respond to his finger as Mike began to roll it firmly. Kathy gripped the hem of her top and pulled it over her head, exposing her breasts to him. Mike pulled her down, took one of the orange size mounds into his mouth, and sucked it.

When Mike heard his youngest sister say, "What are you guys doing?" He let Kathy's breast out of his mouth and looked around her.

"We're just fooling around Mandy," Kathy said as she looked over her shoulder at her sister standing in the doorway.

Mandy walked across the room, crawled onto the bed, and took Mike's penis in her hand. She began to pump her fist up and down the hardening shaft and giggled.

"Do you care if I fool around too?" Mandy asked.

"The more the merrier," Mike said. "I don't mind if Kathy doesn't."

Kathy threw her leg over her brother's lap, pushed him onto his back, and pushed her breast towards his mouth. He took the firm globe back into his mouth and poked at her nipple with his tongue. Mike moaned around Kathy's breast as Mandy took his penis into her mouth and began to bob her head over the length.

Kneeling over her brother with her breast in his mouth, Kathy also groaned when she felt her little sister slide her hand into the leg opening of her short pajama bottoms and touch her labia. Mandy slid her finger between the wet folds and into her opening as Kathy wiggled her bottom at her. Lifting her body, Kathy glanced between her and her brother's bodies to see the top of Mandy's head moving up and down as she sucked Mike's cock. Kathy gripped Mike's hair with both hands and pressed her other breast into his mouth.

Mandy moved her finger from the depths of Kathy's vagina to her clitoris and back as she continued to move her mouth over her brother's penis. Kathy pushed back at her probing finger each time she felt it enter her and groaned as she felt her stomach muscles begin to quiver. Just when Kathy was at the brink of her climax, she felt Mandy's fingers leave her pussy and press against her anus.

"Don't!" Kathy protested, but it was too late. She Mandy's finger enter her tight bottom and slide past her sphincter into her rectum. Kathy cried out at the intrusion, but Mandy did not remove the digit from her bowels. Kathy felt her sister's thumb against her clit and began to relax; deciding the discomfort wasn't as unbearable as she first thought it was.

"Mike, rub my pussy," Kathy said as she began to rock her body against her sister's finger.

Mike moved one hand between her legs, slipped it into her pajama bottoms and down to her opening. He pushed two fingers into her and felt Mandy's digit through the thin membrane that separated Kathy's bowels from her vagina. Mike soon developed a rhythm, pulling back as Mandy pushed in. His youngest sister still had Mike's throbbing penis firmly between her lips and was beginning to increase the speed of her movements.

Kathy moved her breasts over Mike's face and screamed out in lust as her orgasm began to rip though her body. Mike was also at the peak of his pleasure and bounced his hips off the bed, driving his hard-on into Mandy's mouth. His testicles tightened and his penis erupted into Mandy's mouth as Kathy's vagina began to spasm around his fingers. Kathy gripped her sister's finger with her anus and collapsed forward, pulling away from the fingers embedded in her two lower openings.

Rolling off Mike and onto her side, Kathy watched Mandy's throat as she swallowed her brother's cum. When Mike finished, Mandy let his flaccid penis fall out of her mouth onto his thigh and sat back on her haunches. Without saying a word, Mandy stood up on the bed, pulled her nightgown over her head and removed her white cotton panties. She walked forward, one foot on either side of her exhausted brother, and lowered her crotch onto his upturned face.

Kathy looked into her sister's wide-open eyes and saw they were glassy. She watched the naked teen begin to slowly rock her vulva over Mike's open mouth and rub her own breasts, much like the girl in the video she watched the day before. Wanting to help her sister attain the wonderful pleasure she had just encountered, Kathy rose to her knees, took one of Mandy's small breasts into her mouth and began to suckle it.

"Finger me," Mandy instructed her brother. "Put your finger in my kitty and suck it at the same time."

Mike inserted a finger into Mandy's vagina and pushed it in until he felt the resistance of her hymen. Mandy let out a yelp as his finger bumped into the membrane that guarded her virginity and ground her hips into his face. Mike pulled back slightly and moved around tight tunnel, avoiding her cherry.

"Push your finger in deeper, Mike," Mandy begged. "Break my cherry!"

Kathy removed her mouth from Mandy's breast and reached for her brother's hand. "Don't, Mike," Kathy said. "Don't do it with your finger. Someday a guy will break it with his cock."

Mandy leaned forward and Kathy replaced Mike's finger with her own. Being careful not to go too deep, she moved her finger over Mandy's vagina as Mike sucked her hardened clit. Remembering the sensation, Kathy pulled her finger out of Mandy's vagina and pushed it against her anus. Mandy moaned as her sister's finger slid into her bottom and began to move in and out of the tight cavity.

Suddenly, Mandy's body tightened and her juices flowed onto her brother's chin. She yelled out, wiggling her bottom against Kathy's finger, and her clit against her brother's mouth. After several minutes of bliss, Mandy moved away from her brother and reached for Kathy's wrist to pull her hand away. Totally exhausted, Mandy stretched out on Mike's bed and gasped for breath.
