The fourteen year old fox girl stood in the shower with the water off. With one hand she spread her nether lips, with the other she held a test stick. She closed her eyes. Her heart raced as she tried to relax to empty her bladder onto it. Finally there was a trickle and she opened her eyes. She shifted her pelvis to aim the stream onto the stick. After making sure the test pad was fully wetted she let the rest of her urine flow into the drain.

She capped the pregnancy test kit and waited for the results to appear with bated breath. She observed carefully as the result appeared. After a moment she let out a sigh and threw the kit into the trash. She washed her hands carefully and after a moment a grin came on her face as she looked into the bathroom mirror. She opened the cabinet and took out a pair of condoms from a hiding place inside. With almost a skip in her step she bounced out of the bathroom and into her bedroom.

Her one year younger brother was sitting on her bed naked, his fur as equally bright orange as hers. She skipped over to him, holding her hands behind her back.

He stood up smiling and put his hands around her, embracing her while they kissed passionately. After breaking the kiss he asked, ”all ready now?”

”All ready!” She grinned wickedly as she felt her brother’s growing erection against her tummy. She gently broke free from her brother’s embrace and flopped onto the bed.

Her brother followed suit and climbed onto the bed, getting ready to straddle her. But then she held up her hand with the pair of condoms.

”I need you to put these on.”

”Oh?” He looked at the packets for a second, then recognized what they were. ”Oh! Not gonna do it bare any more?”

”Remember what you said you’d do if I got pregnant?”

”Yeah, that I’d have to snuff you to keep daddy from finding out.” He grinned. ”So, you don’t want to risk it any longer?”

”No silly!” She giggled and teased him by pulling her hand away as he tried to grab them. ”Remember what I said?”

”That that just makes it hotter.” He looked at the condoms. ”So why these then?”

She grinned wickedly. ”Because I’m pregnant!”

”You... what...” His heart skipped a beat. ”Uh… Isn’t it a bit late to use this then?” He looked on with panicked confusion.

She playfully tossed the condom packets at him, bouncing them off his chest. ”Silly, they’re so you don’t get any of your cum inside me as you snuff me!”

”But… but… you’re my sister!” He looked down. ”I can’t.”

She propped herself up to sitting so she was face to face with him. She stroked his chin gently. ”You have to. We can't let daddy find out. He'll kill you.” She lifted his chin up. ”Besides, I want this.”

”But...”

”No buts!” She leaned in to kiss him. 

Afterwards she continued, ”I want this. Put one on my head, then wear the other and give me the best fuck of my life.” She smirked when she said the word life. ”Afterwards you can make it look like I was masturbating and got carried away and you can pretend you found me like that. Daddy won’t... no one will ever know.”

He swallowed. Then he nodded. ”Ok.”

She embraced him and gave him another quick kiss. Then she picked one of the packets off the bed and placed it in his hand. As he looked at it she picked the other and started to unwrap it. He then followed suit.

Once she got her packet open, she grabbed his cock and started to wrap it with the rubber. He gasped involuntarily as it throbbed under her touch. 

She had already got him fully wrapped before he got his packet open with his slightly trembling hands. He stretched it a little to make it ready to wrap her head in it.

”You can’t tie me so my wrists don’t bruise, so you’ll have to hold me down.” She laid herself back down on the bed and stretched, arcing her back and pushing her little perky breasts up. ”Now, put it on me and start fucking.” She grinned evilly, fully in command of her own death.

He slipped the fingers of each of his hands inside the ring of the condom, then stretched it until his whole hands fit in. As he reached over to place it over her muzzle his cock pressed against her belly. Again it bounced as it rubbed against her. 

He carefully slipped the condom on her muzzle. The rubber stretched easier than he thought it would and it didn’t take much to pull it then over her forehead, her ears and all the way around her whole head. The rubber was stretched so thin it was almost fully transparent and not just translucent. With a little snap he removed his hands and the condom sealed itself around her neck.

The rubber puffed with each of her breath, and each of her breath some of the air leaked out, leaving the rubber clinging tighter as she tried to breathe in.

He breathed ragged as he watched her. She was going to suffocate. He was really doing this. He was really snuffing her. His heart raced and his cock throbbed needily.

He carefully pushed himself into her, her cunt already slicker than he had ever seen. It felt so good through the condom… almost better than without. He grasped her hands with his hands, pushing them against the bed and then started fucking her, riding her as hard as he could. He wanted, he needed, to make it feel as good to her as he could.

Each thrust he gasped with pleasure, almost out of breath himself. Each thrust the rubber sucked into her mouth as she tried to gasp with him. It didn’t take long for her to start squirming under him as the asphyxiation took its toll, burning through her remaining oxygen at vigorous rate. 

She looked so beautiful like this. The rubber tight on her blueing lips, her chest heaving with each breath she couldn’t take. Her little rock hard nipples poking through her short chest fur with each flex.

He wasn’t sure how much longer he could last as he was already fighting against his own growing orgasm, yet he kept pumping into her without slowing down. Each thrust pushed his peak higher and higher and higher. Delaying the inevitable just one moment longer until he felt his cum dribbling out from his cock and he pushed in one last time, knotting the two of them together.

Together their bodies tensed up, every muscle and sinew. Then together they shivered as their shared orgasm erupted. Each pulse of his cock his strength drained as he collapsed on her, feeling her convulse below him in her own orgasm, until together their bodies went slack.

He lay there on top of her limp body as he gasped for breath. He had never felt such pleasure. He had never felt so exhausted. He could barely move, so he just lay there on top of her. She lay even stiller under him, even her chest not moving. Just her rock hard nipples pressing against him.

Minutes passed quick as seconds as he lay there lost in his afterglow.

Until he could finally stir. Wearily he pushed himself up. His now flaccid cock slipped out of her wet cunt easily. The bed under her was a wet mess. He looked down and saw her slack face. Her eyes were rolled up, her lips a deep purple as were her perky little nipples, now forever hard. She was completely motionless.

He sighed wistfully. He would miss her, but he would treasure this gift she had given him for the rest of his life. He only hoped it had been the best orgasm of her life as well.

Slowly he clambered off the bed, careful to keep the mess between his thighs from leaking out. Standing next to the bed, he took her hands and placed them in her crotch, rubbing them around to get her fluids all over them, before finally pushing couple fingers on each of her hands inside her little cunt. Later he’ll get her phone and put it to play a snuff video next to her, but first he would have to clean himself up.

He went to her bathroom and finally pulled the condom off of himself. He used some toilet paper to roughly clean himself before throwing them and the used condom into the trash. As he did, he noticed the discarded pregnancy tester in there. Something caught his eye and he picked it up curiously.

He looked at it for a long moment. The control line was bright red… but the test line was completely blank, indicating a negative result…
