"Hey cutie!" 

Sypher sang along to Pinkfong while coloring. He suddenly startled when his sister jumped behind him. He giggled as she wrapped her arms around him and squeezed. She gently bit his ear with her sharp cat teeth and stuck her raspy tongue in his ear.

"stop Katy!" he squealed, trying to wriggle away. The two of them rolled around on the floor. Both giggling and squirming playfully. Eventually, she rolled him on his back and straddled him. Katy kissed all over Sypher's face and mouth. It felt weird to him when she did that but he didn't mind. It was kinda nice and he liked smelling her floofy neck ruff.

Katy sat up and her smiling golden eyes looked into his. "I wanna play a game!" She said, gently rubbing her crotch on his. He squeaked loudly when she reached under his shirt and began tickling him. His legs and tail thrashed while he giggled uncontrollably.

"noooo stop!" Sypher said, barely getting the words out. She eased up on her tickling. "your games are mean sometimes! why don't we watch cartoons and color?"

"I wanna play astronaut!"

"i don't think i like that game Katy…" he said, recovering from the tickling fit. "i couldn't breathe when we did it before!"

"C'mon silly, that's part of the fun! Besides, Daddy does it to me all the time and I really like it. Last time we did something really cool and you'll like it too! Trust me." She grinned, her eyes twinkled hungrily.

"i dunno…" he mumbled, "i wanna draw."

"I promise I'll draw with you later, lil guy. But right now we're gonna put a bag on your head!" Katy said cheerfully. She glanced behind Sypher and grinned.

"ok i guess we—" The bag came over his head and panic set in.

Sypher felt it cinch behind his neck and immediately sucked in a deep breath. The plastic squeezed tightly against his face and formed a seal over the sable's mouth and nose. He tried to breathe in but the gasp was cut short like slamming into a wall. Sypher didn't even realize he was clawing for his neck to get the bag off of him until he felt Katy squeeze his wrists and pin him down.

Mortal terror flooded his system. He could feel imminent death. His face grew hot as blood rushed into it. His chest shuddered as it failed to suck in air. Sweat broke out across his entire body and filled the bag with moisture. Tears clouded his vision and his eyes bulged. His head thrashed and tail flailed. His whole body convulsed, except firm hands held his head in place and the seal of the bag tight. He could only look up.

He couldn't see her face, just some bright red and tawny blotches in a shuddering blur. But he could feel her eyes boring into him: sadistic golden embers driving straight into his skull. Her blurry shadow loomed over him. Her weight pressed down on his groin and slowly moved up and down his torso. But it was all distant, like the sensations were far away.

As spots began to dot his vision his thoughts raced. She was going to kill him. Stop, stop, stop, stop! He was going to die. In his silent screams he pleaded for Katy to let him go, to let him live. Why wouldn't she stop?! Killed by his own sister's hands… The spots swam and the panic grew white hot. He heaved his body as hard as he could, mustering strength he didn't know he even had. He felt one of the hands gripping his wrist begin to lift. The implacable weight on his torso began to shift. He could do it! He could get free! He wasn't going to die. Sypher strained his muscles to the limit and beyond. He was a sable and sables can get away! The hands holding him down were budging!

Slammed back harder than ever, the spots in his vision exploded as his head hit the carpet. Sharp claws dug into his arms as they were forced back down and pinned to the ground. The weight crushed down. The trap snapped close on him. Fighting back was useless and there was no point. It was stupid to think he could get away. Nothing other than to accept his fate. If only it didn't hurt so much. If only it wasn't the family that was supposed to love him. They were so cruel. Maybe this was the way out. He shuddered uncontrollably as the world grew dark. The little 7 year old sable boy welcomed it.

He couldn't tell when the bag came off, but fresh air exploded into his lungs. It stung like a billion needle pricks going off inside of his chest. His inhalation went on and on forever. His body trembled but the panic evaporated instantaneously. Fear metamorphosed to joy in an instant. He was alive!

Soft paws gently ran through his sweat soaked hair. He could smell her sweet ruff in his rapid breaths. She nuzzled her nose into his ear. "I love you little guy." She whispered, and Sypher knew it was true. He just wanted to be held in his big sister's arms. He wanted to tell her that he loved her, but his heaving breaths wouldn't let him form words. He didn't want to play this game anymore, he just wanted to be held.

Another, larger hand caressed his face. Another blurry figure appeared above him, he saw his older brother Jeremy looking down. As Sypher panted he heard a hocking noise but then felt a large glob of phlegm drop into his gasping mouth and slide down his throat. Before he had the chance to try to spit it out Katy's mouth clasped over his and her tongue plunged into his mouth, as though she were chasing the disgusting blob of slime. She squeezed his button nose, cutting off his air, once again.

Sypher did like it when she kissed him, but not like this. He tried to move her arm away from his nose but Jeremy must have been holding him down. Her raspy tongue caressed his. She was bearing down on him and he couldn't turn his head away enough to breathe through his mouth either. Her hips rocked back and forth on his leg and he felt her other paw slip under his shorts and grip his little penis, which stiffened as she stroked it up and down. 

Suddenly she leaned back, but before he could take another breath she punched him hard in the gut. All the air fled his lungs and when he tried to gasp it was plastic that sucked taut over his face. Adrenaline flooded Sypher's small body for a second time when the bag was pulled tight. He saw stars and spots again flashed in his eyes. His face was immediately damp from sweat and spittle. He tried to flail but his limbs were so weak. This was it. They were going to kill him. The world finally went black.

He was being fucked. When did that happen? But he was breathing again. Sypher's eyes fluttered open and he gasped. "Woah! He just got so fucking tight right now!" His brother's words sounded far away. But there was precious air… for now. His body was numb and the cock moving inside him barely felt like anything at first. But then he felt the painful stretching and impact as it slammed deep inside him. As his consciousness returned his rape hurt more and more. His insides ached amid the battering. How long had Jeremy been using him like this?

The bag closed in again. He knew it would. The fucking didn't stop. Instead it sped up. Remy's cock kept slamming into his guts. Each impact forced more air out of his lungs. It felt like the cock was penetrating deep into his chest and ramming directly into his pounding heart. Tears flooded down his face from the pain and violation. Sypher just hoped it would be over. Maybe he would pass out again and they would have finished their fun by the time he woke up. But that was wishful thinking and he knew it. Sypher wailed in hopeless agony. He struggled helplessly in a familiar panic, kicking and trying to scream in vain. He wished he could just pass out and not have to experience this anymore.

Right before things began to fade, something different happened. There was a clink and a wooshing noise. Then he felt something poke between his neck and the bag. It was too hard to be a finger but it was about that size. Then he heard another, slower hissing noise and cool air filled the bag! He took a deep breath filling his lungs as much as he could. But something wasn't right. The air tasted strange, cloying. Something was wrong. Really really wrong. His head swam. He could feel his heart beating in his eyes. A swishing noise filled his head: "Whew whew whew whew". His vision flickered. The spots in his eyes pulsated in time with his heartbeat. Distantly he heard laughing.

Sypher could breathe, but it wasn't oxygen. It was something else. The initial relief of simply being able to inhale turned to horror. He didn't know what he had been breathing. It could have been something poisonous! He didn't know what they were trying to do to him. He tried to struggle but his limbs felt floppy, like they had gone boneless. He was hyperventilating. The massive object moving inside him felt so strange. It was a giant tentacle depositing eggs inside his body. Spiders were going to burst out of his belly. They were going to eat his brains and turn him to mush. His body fell apart, melting. His belly was inflating and he was going to burst open. He was sinking into darkness, enveloped by the floor which reached up with a slimy embrace. He fell into emptiness: the black abyss of space. Like an astronaut, plunging into the void.

He woke up gasping. Again. His entire body was slick with sweat and he felt cold. A soft paw caressed his cheek. Warm lips kissed his face. He smelled her and wanted to be held in Katy’s arms so badly. It took a minute for him to notice but the familiar sensation of his insides being rhythmically pounded returned. It was fine, as long as she was touching him. She snuggled him and lightly ground on his belly while their brother groaned and shot another load inside him. His belly was getting swollen. That part was real.

"Mom made me put this on you." She lifted Sypher’s limp arm and he could feel something on one of his fingers. 

"wha?" He could barely think, let alone form words. It was a struggle to breathe. The fact he was still being fucked didn't make it any easier.

"It's called an 'oximiter'. Mostly to make sure you don't actually die from oxygen loss. You got really low!" she said proudly. "We almost killed you!" She grinned and wiggled as though that were an accomplishment.

"oh…"

"Did you like the last thing we did?" She grinned and practically bounced. Her enthusiasm was so palpable it almost made him smile.

"huh?" It took him a minute to realize she was talking about the wretched air. He shook his head vigorously. He was still feeling the pulsing effects and shaking his head made it a hundred times worse. It was like his brain was shaken like a carton of orange juice. (Juice sure would be nice, though…) Strange noises still played in his ears. His vision followed and sloshed around his head as he tried to look at Katy. Her eyes were golden streaks that swam in his vision.

"Aww." She gave him a look that made it clear she wasn't the least bit sorry.

"Katy?"

"Yeah, baby noodle?"

"can we stop now?"

She looked disappointed and Sypher felt a little bad as though he let her down. Remy slowed down his fucking to look at her and shrug. "Your call," he said.

Katy tapped a finger to her lips, seeming to contemplate an important decision. "How about… just one more thing and then we can go back to drawing?" She grinned, showing off her sharp teeth.

"okay, i guess…" Sypher mumbled resignedly. He didn't want to disappoint her.

"Yay!" she clapped. She crawled on top of him and reached out of view. "Trust me, you'll like this." There was a rattling noise and then the familiar clinking noise and woosh. Sypher tried to squirm and protest. She pulled out this weird bottle thing and put a part of it in her mouth and pulled a lever, causing the hiss. She squinted trying to hold in the weird air. At the same time Jeremy finally pulled out of his aching butthole and Katy grunted as he slipped into hers. Then she leaned over and kissed Sypher.

She began to exhale into his mouth. Her body rocked gently against Sypher's as Jeremy fucked her slowly. The strange air filled him, but he wasn't as worried this time, at least until she pinched his nose closed. He started to struggle, but she calmly took his paw in hers and brought it to her own nose, and guided him to squeeze it. He pinched under her azure nose ring. Now she couldn't breathe either. She sucked in and Sypher realized he should exhale back into her. It's like they were sharing a single deep breath.

The world flickered as the strange air took its effect. But he could feel her shudder as the same effect took hold of her. Her body pressed into his rhythmically with increasing insistence. They swapped breaths until time blurred. Finally she pulled away and they both gasped. She went limp on top of him, moaning with pleasure into his neck. He inhaled her scent and heard her purring. It was a quiet rumble that caressed his entire body. He still felt the disturbing effects of the air, but it was weirdly pleasant this time. The way she rocked back and forth was so nice and so gentle. He was warm and content.

Then, of course, she reached out of view, and the bag closed tight, yet again.

Sypher lost count, but he awoke breathless several more times. At one point Katy straddled him with her pussy blocking his nose and her butthole covering his mouth. Remy's cum slid out of her butthole and down his throat. Later, Remy choked him with his cock and pinched his nose, while Katy was sucking his soft cocklet. Each time he woke up they were doing something different…

When it seemed like the cycle would never stop, he woke up sitting on the couch swaddled in a blanket. Katy handed him a mug of hot cocoa. After he took it she wrapped her arms around him and kissed his cheek. "I love you so much," she whispered gently into his ear. She snuggled close and purred warmly, tucking her cold wet nose into his neck. 

Pinkfong was back on the TV. His pencils, markers, and drawing paper were neatly arranged on the coffee table, along with a small plate of warm chocolate chip cookies. The aroma of fresh cookies filled the room. There were also glasses of milk and orange juice. Sypher's eyes lit up and he squealed. 

Katy moved off the couch and knelt on the carpet in front of the table and took a bite of a cookie. She pulled out a page for herself and took his hand. "C'mon, let's draw!"
