Mark sat at the kitchen table, reading the news on his tablet. The evening light from the setting sun filtered in through the window as he lazily flicked through the headlines in the news app.

A teen wolf girl skipped in to the kitchen.

Mark glanced up and saw that she wasn't wearing anything. A short tinge of arousal shot through him as he saw her perky little breasts. Instinctively he glanced down at her nethers. When she had been younger her fur had hidden her lower lips almost fully, but now that she was growing up the pink was showing through.

Mark turned back to his news. “Hi honey. Put some clothes on, will you”, he said offhandedly.

Tina took no heed and skipped up to Mark. She leaned in behind him and wrapped her arms around him. “Heey daddy”, she cooed into his ear. “I want to play our snuffy game tonight.”

Mark's heart jumped with sudden excitement. He thought about it for a moment. “All right.” Then turned to look at her. “How are you going to kill me today?”

“It's gonna be a surprise. Just go to the bedroom.” She kissed him on the cheek. “Since tomorrow is my birthday, I'm going to take your life as my present.”

He smirked and rose up. “Ok.” There was already a bulge in his pants as he walked out towards the bedroom.

She followed him closely. She was still his little girl, but she had grown considerably since the first time they had done this. Instead of being only waist high, at 15 years of age, she was now up to his chest. But when they played this game, she was in charge and he was her little sub.

He stopped in the bedroom and turned to face her. “What do I do now?”

She looked at him playfully sternly. “Strip down and lay on the bed.”

He started to unbutton his shirt. He made a little show of it for her, carefully letting her watch his body move as he gyrated.

She may have liked his strong naked body, but he was still her dad and at times like this she thought it would be her who would die, of embarrassment. “I didn't mean like a stripper, daddy!”

He chuckled and threw his shirt to the chair next to the bed. He resumed pulling down his pants, more seriously this time, and she approved when his already large erection plopped out. He kicked the pants towards the chair as well, and then lay down on the bed on his back. His red knotted cock pointing straight into the air like a mountain.

“Arms and legs out!” She was back in the dom mode now and ordered him to position on the bed. She went to a drawer near the bed and fished some rope out. Carefully she went through each of his four limbs and tied them to the bed posts.

Mark tested his bonds. She had become very adept at knots over their many times playing and he was quite secure and completely at her mercy now. He couldn't move more than a few inches against the ropes with his body splayed out on the bed.

She admired her handiwork – and his body. “You look so good like that daddy.” She grinned evilly. “And you'll look even better once you're blue and dead.”

Each of those words made Mark's heart race faster. He knew she was only playing, teasing him, but to him those words were real. Deep down in his core he yearned for them to be. First time they had played this game he had died. He had hung from the noose and surrendered everything with no expectation of living. When she had said goodbye to him it had been the best feeling in the world. A world he let go of and embraced the darkness. But he hadn't died. Before his heart had stopped, she had cut the rope and he came back. Every time they played after that he knew they were only playing, but a part of him still yearned for it to be real.

Next Tina took out a ball gag from the drawer. “Open mouth!” When he obeyed, she slipped it in and secured the strap behind his head.

She stepped back to the drawer and took one more item. Careful not to show it to him, she held it behind her back. “Are you ready to see how you die?”

He could only mumble in agreement.

She climbed on the bed, still holding the item behind her back. She straddled his stomach and he felt her little wet cunt brushing against his fur. His cock pulsed with anticipation. She let the moment stretch on... then... she held up a plastic bag. “You're going to suffocate, while I ride you all the way to heaven.”

He could say nothing, he needed to say nothing. His cock bounced with excitement as she slipped the bag over his head. She puffed most of the air out and secured the bag around his neck with another rope, tight, only barely loose enough to not to strange him.

It didn't take long for the little air inside the bag to start to go stale. And he breathed faster, harder.

She moved back and placed herself on his cock. Slowly she lowered herself on it, one inch, two inches, three... four... all the way until his knot was pressing against her lips.

He squirmed with pleasure as she started riding him. He squirmed with distress as the air grew staler. 

She admired his rippling muscles under his fur. Flexing, straining against the bonds. Her heart raced with pleasure. But also with nervousness. 

After a few moments of riding him, she placed her hands on his chest. She could feel his heart beating like mad under her hands. She leaned forward.

“Daddy...”, she spoke, “remember the first time we did this?” She paused. “I told you I would kill you some other time.” She pressed her body against his. “Tomorrow I will be sixteen. Today is the last day I won't be tried as an adult.” She leaned close to his ears and whispered, “goodbye, daddy.”

She felt his heart skip a beat. She rose back up and pressed down further on his cock. She grimaced, and for the first time his knot slipped inside her. Even as he was already slowing down, she resumed riding him, harder than she had ever done before.

Mark's lungs burned, the plastic clung to his mouth as he strained to draw a breath. He felt her fully on his cock, and it felt so wonderful. He felt so light headed, and it felt so wonderful. Deep down he didn't yearn anymore. Deep down he knew it [i]was[/i] real. And it felt so wonderful.

His entire body tensed as his orgasm erupted inside her. His [i]final[/i] orgasm. And it felt so wonderful.

She gasped for breath as she felt him fill her to the brim. His seed spilled from her cunt, splashing between them. She felt his body tense and then slacken. His chest fell. His head lolled to the side. Still and silent, even the plastic over his face stopped crinkling.

With her own orgasm subsiding, she lay her head on his chest. She could hear his heart beat. Fast, fast, fast... slow... still.

She closed her eyes as she lay on his corpse. His knot still inside her, still hard.
