Jon held a solemn expression as he watched his beloved sister writhe beneath him in discomfort. While he absolutely ignored her wishes in order to establish the current situation, he always hoped she would grow to accept it and him. It seemed as if she had been fighting against the idea though. If she even had the slightest feelings for him, she was determined to ignore them.
Slightly angry at Tiffany for refusing to accept him, he grabbed a fistful of her hair and pulled her head back, straining and arching her back. She tried to reach back to free his grip but he seized her hand and pulled on it too, twisting the joint painfully. Water filled her eyes as he pulled her back into him as far as he could. She moaned as she felt his cock filling her. Watching her squirm in discomfort was turning him on. She could feel his cock entering her even further.
He wound his fingers in her hair and pulled it up from the back of her neck. He kissed her exposed skin gently, in contrast to how hard he was fucking her. She gasped and squeaked but tried not to make enough sound to raise suspicion. She felt odd knowing he was in complete control of her body. More and more of herself was being exposed and it was the last thing she wanted in the early morning. She would rather stay warmly tucked under her sheets.
Tiffany tried to reach up to her bed with her free hand, putting all of her weight on Jon to hold her up by her hair and her other wrist. When she grabbed the edge of her sheet, he jerked her away. “I’m cold,” she whined miserably.
“I’ll give you something warm” He pulled her closer to him. Without hesitation she leaned backward into him until her back was touching his bare chest. His skin was cold on contact but it began to warm up immediately. She moaned as she closed her eyes and tried to fidget in his lap.
Jon let go of her hair and wrist and instead wrapped his arms around her waist. His hands found the triangle of her crotch and traveled down until they touched the lips of her cunt, particularly her clit. She gasped and jerked in response, trying to stand up to escape but failing to find her footing. Instead she plopped back down on his cock with a guttural groan as she swore the tip must have punctured her cervix.
Seeing an opportunity, Jon brushed against her clit again, causing her to suck in a large breath. When she did not move, he pinched it. Once again she leapt from his lap only to fall down once more a moment later. She covered her mouth to keep from screaming while rolling her eyes back in pain.
Jon continued to pinch, roll and flick her clit, making her bounce jolt and flinch. Pretty soon she was writhing and thrashing about, trying not to make too much noise as she unintentionally fucked herself on his pole. Jon could feel his orgasm approaching. Tiffany’s movements stimulated him in an unfamiliar way that was harder on him to resist. He grabbed her by the waist and prepared to lift her off of him. He was still looking forward to cumming on her creamy smooth back.
“Don’t,” she groaned while grabbing his hands with hers. Instinctively he dropped her again, causing her to groan as his cock slid all the way back inside her. It pressed hard against her pelvic bone the whole way down. “Cum inside me,” Tiffany whispered hoarsely. “I’m cold. Warm me up, please,” she begged him.
Just those words from his sexy naked writhing sister were enough to push Jon over the edge. His first spurt of cum exploded right into her pelvic bone. He lifted her up so that it sprayed and coated the inside of her cunt all the way down. Then he slammed her back down on his cock, pushing the tip against her closed cervix. She screamed in pain but it quickly subsided as warm cum splashed against the raw opening.
Tiffany’s body reacted appropriately, gushing clear liquid to slick the path for his cum to slide inside her womb more easily. Her body wanted to be impregnated by her brother’s cum. Jon continued to pinch and roll her clit as they came together. She bounced and spasmed and thrashed, driving his cock into her and making her scream. She bit her own wrist to keep the noise down. Her newfound wetness allowed his cock to slip around inside her and touch all of her walls.
Although she was now warm inside, the liquid running down her legs only brought Tiffany more discomforting cold. She was shivering and her nipples had grown stiff. She covered them with her hands in an attempt to heat them up. This sent a sharp jolt through her body that caused her to hop up and down on her brother’s cock again.
Jon gave one last spurt of cum into his sister’s warm slick cunt before collapsing against her back. She could feel his breath in her ear as he panted in exhaustion. “Don’t stop,” she whispered to him. “Keep fucking your slutty sister’s wet cunt. Make me scream and cry.” Jon chuckled at the idea but he was definitely done. All she could do was give him empty demands. “Come on, Jon, fuck me,” Tiffany raised her voice unexpectedly.
It was at that moment that both of them heard the sound of footsteps outside their door. One of their parents had been right outside and had definitely heard her. The thumping suggested they were checking Jon’s room, presumably to see if he was still asleep and if Tiffany was just moaning his name in her sleep. When they had their answer, they returned to the room.
The door swung open to reveal Lauren Taylor in her morning bathrobe. Her hair was tied up atop her head as she often did when she wanted to take a shower without getting it wet. Her face was beat red and she was glaring straight at her children. “What the hell are you doing to him?” Lauren demanded while pointing at Tiffany accusingly.
She did not answer. She instead tried to stand up. Jon’s flaccid cock slipped out of her easily but her legs were weak. She managed to stumble only a few feet ahead before collapsing against her bed. “What do you have to say for yourself, young lady?” Lauren demanded. “What in god’s name possessed you to do this to your brother?”
Tiffany felt a seething rage boiling inside her. “He did this to me!” she shouted at her mother. “Why do I have to take the blame when Jon’s the one who snuck into my room and raped me?”
“Don’t you dare say that about my sweet Jonas!” Lauren spat at her. “Look at what you’ve done to this family. I’m calling my sister right now. You’re going to live with her in the country until you turn eighteen and then I never want to see you again.”
“Mom, wait!” Jon interrupted her.
“Don’t you say a word, Jonas,” she scolded him. “Mommy will take care of this slut.”
“She’s not a slut, she’s my sister and I love her!” Jon shouted.
“Don’t be ridiculous. There are plenty of proper girls out there. You could have anyone you wanted,” Lauren tried to convince her son.
“I want Tiffany. I’m in love with her. I want to keep having sex with her and no one else. Won’t you let me, Mom? You always let me do whatever I want,” Jon reminded her.
“I…” Lauren was at a loss.
“What’s going on here then?” Randy heard the yelling from downstairs and came to investigate. The first thing he noticed was his naked daughter, covered in sweat with two types of cum dripping from between her legs. She wore a look of embarrassment and shame that shown more clearly than any expression Randal had seen her make before. He was, after all, not at home all that often. “Um, what’s going on?” he repeated his question.
