*****
Nick woke that morning at his sisters side. Still asleep, she lay naked next to him in her bed. Nick admired the smoothness of her back. He lifted the sheets a little to expose her bare ass. His cock was hard within seconds. He felt himself growing and hardening as he stared at the crack between her cheeks. He swore he could see the light brown shade of her asshole.
This was Jennifer's naked body that was next to him. He'd never seen her in the light of day, in all of her beauty. The girl he'd grown up admiring, the girl he'd always looked up to and wanted to be like. He was now in her bed after a night of exerting sexual fun.
Naturally, he moved closer to her. She slept soundly as he shifted towards her in the bed. His cock made contact with her naked cheeks as his abs pressed against the small of her back. His knees found her kneecaps and he wrapped a long arm around her.
"Morning." He kissed her cheek.
Jennifer couldn't have wished for a better wake up call. She felt so safe in her little brothers arms. His breath against the back of her neck soothed her as the early fog cleared from her mind.
"Morning..." she groaned.
Nick hugged her body. Looking over her shoulder, he could see directly down her cleavage. Her nipples were covered by the sheets but the valley between her breasts were not. His cock pulsed against her.
"Ahhh... morning glory." She sighed.
"Is it that obvious?"
"It's 7 inches long and stabbing into me. Yes it's obvious."
An awkward silence fell upon the room.
"Well aren't you going to get on with it?" She asked.
"What? You mean?... right now?..."
"Yes, right now?"
For a minute, Nick didn't know what to do. Did she want him to jerk off right there and right next to her? Did she plan on helping him out? What was it that she meant for him to do?
"Here," she finally said, "just put it against me."
Naturally, Nick's cock found the safe place of her asscrack. His banana shaped penis nestled into her curves quite easily. It felt so right for him to be up against her like this. He couldn't resist the urge to thrust.
Gradually Nick humped against his sisters behind. She arched her back a little and stuck out her bum for good measure. Jennifer took hold of his arm and wrapped it around her body. Where she placed his hand over her left breast. Nick needed at her bosom as he dry-humped his sister.
After a while, Jennifer's body had begun to react to what they were doing. She felt herself moisten between her pussy lips. Like an oven that had been preheated, her vagina gradually increased in temperature.
Jennifer could feel his warm penis against her cold bare ass. She even started to grind back against him, hoping he would stick it some place else. The feeling of her bare skin against his cock was a warm, arousing feeling. Nick had gotten so carried away that he'd accidentally thrust his cockhead against her asshole.
"Now, now, brother. We aren't doing that today."
Nick couldn't help but think this meant it was a possibility.
"If you must, put it here instead."
Her soft fingers took hold of his girth and she directed him to her pussy. Even now the feeling of Jennifer's fingers holding him was enough to make him bust. His head was immediately lubricated as her pussy lips smothered him and he slid inside of her quite easily.
Jennifer felt his warmth invade her like a hot poker. Stabbing into her sex filling her with sexual comfort. She hugged at her pillow and closed her eyes.
Nick closed his eyes too as he enjoyed the feeling of his cock disappearing inside her wet canal. Her ass was now pressed fully against his groin as he rocked back and forth, in and out of her.
Jennifer appreciated that Nick would hug her tighter to him each time he thrust into her. His quiet grunts only turned her on even more.
"Hmmm, that feels good." She moaned.
Encouraged, Nick increased his speed. Not to the point he was desperate for orgasm but to the point where he felt he could build on something.
The feelings around his cock gradually increased in pleasure. Her suction around his length was different to what it was last night. Perhaps because sex this morning had come so quickly, She hadn't enough time to loosen up.
He held her hips now as he concentrated on fucking her from behind. They both lay on their sides as he drove himself in and out of her.
"Kiss my neck." She demanded.
Nick planted soft kisses on the back of Jennifer's neck, just below her baby hairs. She wore her thick and dark hair up in a bun when she slept. They'd had magnificent sex the night before and now he was being treated to some more.
He could smell her conditioner in her hair, he felt how soft her strands were as they brushed up against his face. He soon felt his balls tighten and his orgasm creep up on him. His balls contracted in their sacks and his cockhead felt like it was being tickled.
"Jennifer!" He yelled.
Somehow Jennifer knew exactly what he'd meant. She whirled around within a fraction of a second. His cock had slipped out of her pussy abruptly. Now her tight fist had taken its place as she pumped him up and down as fast as she could. She even scooted down the bed so that her breasts were in direct aim for him.
Nick stared at the target of two massive, milky breasts, with small nipples in each centre as he blew his load. It wasn't as much as last night. However, watching his cum soak his sisters large tits, it brought about a strong orgasm all the same.
"Thank you..." He groaned, it was all he could think of saying.
"Not a problem" She smiled up at him.
Nick stared at her some more until she told him to go get tissues from the bathroom. He awkwardly waddled across the hall with his boner swaying in mid air.
He returned with the tissues and to his delight, Jennifer let him clean her up. Once she was clean, Jennifer kissed him deeply. She didn't have morning breath and that was a relief, Although it was kind of expected. Nick never really thought of any hot girl to have morning breath.
"Would you look at the time." She said.
Nick twisted his body to take a glimpse at her alarm clock.
"Take me to school?" He asked.
"Why not, suppose I'm feeling rather generous today."
Nick hoped that this meant more fun for when he returned home from school.
Rebecca hadn't returned home in a week. She'd stayed at her friends, hiding away from the problems that she had at home with her brother and sister. She couldn't stop thinking about her kiss with Jennifer in the car. It sparked something inside of her that she'd thought long lost.
Sometimes when she masterbated, she thought of her sister, sometimes she thought of her sister and brother together. The threesome that Jennifer had mentioned seemed to find a place in her mind several times a day.
Today was the day that she would be returning to face the music. She thanked her friend for letting her stay so long and she left with her things that morning.
Jennifer had been texting her, filling her in on what had been happening at home. She'd mentioned them going to look for a suit today. Nicks dance was coming up, it was only a few days away. She'd found out that he was going with Jessie, Rebecca couldn't help but feel jealous about it.
Finally she arrived home after a long highway drive. She put the key in the door and entered.
"Hello?" She called out into the empty house.
"Rebecca?" Called Jennifer's voice from upstairs.
