The teenagers first reaction, when he cummed in her mouth, was to gag.  Although she jerked at the rope tying her paws behind her back, she managed to keep her muzzle closed so none of the seed escaped.  It was not her first time swallowing his seed; she didn't like it but she did it.  She ran her lips and tongue over the length of his erection to ensure he was completely cleaned off.

She sat back on her heels.  He heaved up off of the floor and stood up.  Then, he helped her to get up off of her knees.

"Are you going to untie me?"

He reached out to grab a rope that ran up over the rafter.  The attic had become thier private sex and bondage place, because it was the best place to keep thier ropes, and hide what they were doing.  The bondage was his kink, not hers.  She went along with it, because it aroused him so much.

He reached up to take down the end of the rope where it rested on the rafter.  "I, uh, want to try something different," he said.  He pulled down the end of the rope, and she could see that he had tied a noose to it.

She tilted her hips, and pouted at him.  "Is that for me?"

"I - Yes."

She smiled, closed her eyes, and stretched her head out to him.  After a moment she felt the rope slip over her muzzle, over her ears, and fall down around her neck.

"Look, uh, I, uh -"

She looked up to him.  "It's alright.  I understand."

He paused.  There was a strange look in his eyes.

"You can't let your wife find out you've been fucking the teenager next door, can you?  And since I'm only fifteen, legally its rape; even though I seduced you." She smiled sadly up at him.  "I knew that when I told you I'm pregnant, it meant I'd never see sixteen."

"I don't want to -" be began.

"Oh, of course you want to," she interrupted.  Looking down at his rapidly returning erection she said: "I can see how much this is exciting you."  Smiling impishly she asked: "are you going to fuck my body after I'm gone?"

"No, I mean, uh, well, yes, I do want to kill you that way.  But, I would much rather keep fucking you."

"And, maybe kill your wife instead?  Frigid shrew; she deserves it."

"I can't do that."

"I know."

For a moment they both stood there thinking of missed opportunities.

He turned to loop the running end of the rope through a ring bolted to the wall, and pull up the slack lifted the rope up beside her cheek.  He turned to look at her.  "In a way, I did love you."

"I know."

He heaved on the rope.  When her feet were a good fifteen centimeters off of the floor, he struggled to secure the rope to the anchor ring.

The noose slipped up tight to her jaw and dug into the tender flesh of her neck.  The knot slipped up behind her right ear, and pushed her head down to the left.  For a long moment she just dangled there.  Then her belly began to spasm, causing her legs to fly back and forth.  She shuddered, and her naked teats bounced on her chest.  He was surprised to see that her nipples were erect.

He quickly snatched her discarded panties off of the floor and wrapped them around his erection. He began to stroke himself while he watched her strangle.

Her tail flit madly about.  She began to bycicle her legs.  Her eyes were half lidded, the pupils rolling up until they were almost hidden.  Her lips peeled back from her grit teeth.  Then, her legs spread out wide to the sides, and her tail stiffened behind her.  Her body shook violently, flopping her teats up and down.
Suddenly, she went limp.

He filled her panties with his seed.
