The girl roughly pushed the boy away as she made her way into the house. He counterattacked, pulling a messily braided cluster of hair that spilled forth from his sister's head. "Ow!" The female angrily growled, jabbing her fingers into one of the boy's eyes. His hands reflexively flew to the injured orb, allowing for his sister to trudge into their home. "Wait a minute!"Tuffnut snarled, running after the twin and grabbing hold of her shoulders from behind. "You're such a bitch!" Came low growl, the whisper in his voice more terrifying than that of most yells. "You're so ugly!" The girl spat back, trying her best to wiggle free from her brother's grasp. "Tch, you look just like me." He retorted, watching as his sister rolled her eyes. It wasn't getting to her. He need something else. He smiled as he thought of that something. "Except you have THESE." He teased, hands snapping from her shoulders, moving their way forward to roughly grab a breast in each hand. "S-Stop it!" The girl replied, too shocked to physically react. The girl had recently begun to develop, and the small buds that had graced her chest had now blossomed into flowers. Very, very large flowers. "Damn sis, these are HUGE!" The boy commented, impressed; hands overflowing with his sister's bosom. The boy's teasing smile turned to a frown. He had never really realized that his sister was, well, attractive. He was, to put it bluntly, outright turned on. She was hot. "Can you get off!" The girl angrily murmured, she wasn't in the mood to fight anymore, all she was was embarrassed. "Sis, you've grown a lot, huh?" The boy asked, a bit of sincerity actually wishing into his barbaric tone. "Huh? Yeah, I guess. Get off!" The girl rived a bit, she was annoyed, she didn't want to talk about this, not with anyone, even her brother. "I've grown a lot, too, y'know..." He whispered, hips pressing into the girl's rear, grinding lightly against her. "What... What the hell? GET OFF!" Ruffnut yelled, doing what she could to elbow her brother in the stomach. Her plan failed, proven as he took hold of both her hands in one of his own, quickly looking around and grabbing some building rope from the table beside them. The female viking roughly pushed against him, doing her best to release herself from he other's grip. It was to no avail, and soon, much to Ruffnut's dismay, she sat, feet and wrists bound. "Tuffnut! What in Odin's name is going on!" She screamed, tugging against the ropes in desperate hope for escape. "LET. ME. GO!" She yelled, body violently squirming on the floor. The dominant male grinned down. Watching his sister's well formed body rive and struggle before him. He felt as his manhood began to erect, rubbing through the thick wool pants to find a pathetic form or release. A look of fear flashed through his sister's eyes as she began to understand what was happening. "Tuff... Don't do it!" Came her desperate call, even her thunderous voice being brought down. "Shut up." The boy snapped, pulling a chair out from beneath the table and taking a seat within it. "Scoot on over here." He grinned. The girl stared at him, disgust filling her face. "Fuck you!" She spat, wobbling as she slowly began to rise to her feet, hoping to be able to hop away. The boy quickly rose from his seat, angrily snarling as he thudded over to the girl, grabbing onto one of the matted braids once more and roughly pulling her over to the chair. He yanked the hair down, watching his sister flinch in pain as she obediently dropped to her knees. Tuffnut continued to hold the locks within one hand, the other now reaching into his trousers to pull out his throbbing erection. He did so, a pearl of translucent precum rolling down his shaft, glorifying the magnificent stick of meat that he held within his hand. Ruffnut's eyes widened. The last time she had seen her brother fully naked was a bit before puberty, and since then he had... well... grown. A LOT. "Suck it." The boy commanded, snapping the girl from her trance. "No!" The girl yelled once more. This was wrong! Her brother angered once more. "It wasn't a question." He growled, hand burying itself within the locks upon the back of her scalp, pushing her head forward as he roughly began to rape her mouth. The girl choked, tip of her brother's cock roughly bouncing off the back of her throat. She did her best to scream, though the large shaft muffled almost all of her cries. The meat continued to pound itself deep within the girl's throat, and after a few moments, the viking upon the floor felt her gag reflex begin to kick in. Her choking turned to gagging, and not long after, vomiting. "Oh nasty!" Tuffnut declared, pulling back his sister's head as her partially digested slop was spewn onto his dick. Ruffnut fell back, choking for air as the remainder of her vomit fell onto her chest. Tuffnut panted, looking down upon his sister as he asked, "You okay?" Ruffnut looked up at him, disgust entering her face once more. "Hurr, I don't know retard! You didn't just make me try to suck your shit!" She sarcastically waled, not quite sure how else to react. The flushed anger returned to the boy's face. "Then if you don't want to suck it, how about you mount it?" The boy retorted, leaning back in the chair, allowing his sister to get a good look at his vomit drenched erection. Fear flashed through her eyes once more as she wildly shook her head. "No!" The braid of hair still lay in her brother's fist, and as she refused, he roughly yanked it upwards. The girl whimpered as she was forced to her feat. "Take it off." The boy nodded his head to the fur skirt that lay round his sister's waist. "You're an ass!"
