Brenda took her shirt by the waist and pulled it up  over her head.  Her hair spilled out as she tossed the shirt into the waiting basket.  It felt funny stripping out here where everyone could watch.  The teen age doe reached around in back and began to unbutton the skirt waist over her tail.  Embarrassing funny, but also sexy funny.  She pushed the skirt down over her pregnancy swollen belly, and let it drop to the floor.  Sexy, because most of the people in the audience were going to enjoy a sexual thrill watching her.  She unclasped her bra, and shrugged it off of her shoulders.  But that was alright; it made good sense for people to enjoy it.  She hooked her fingers into the waist of her panties, and pushed them down to the floor.  Even if it was all so embarrassing.  She squat down to pick up her skirt and panties and stood to toss them into the basket.  She heard a murmer in the crowd, and selfishly hoped that it was appreciation of her cute naked body.
Brenda's mother had stood patiently waiting for her to finish undressing.  Now it was mother's turn.  The older doe smiled and began to unbutton her frock, from the low cut bodice to the knee length hem.  Mother slipped off the dress like a coat, and tossed it at the basket, where it slipped off and slithered to the floor.  She untied the pink ribbon at the top of her lacy corset, and slowly pulled free the six hooks down it's front.  Freed of thier restraint, mother's heavy teats sagged down over her age softened belly.  Still, they were large enough and plump enough that Brenda thought the audience would have no call to complain.  And finally, mother took her panties by the waist and slid them down to the floor.
Once the panties joined the other clothes in the basket, the two does, mother and daughter looked at each other for a moment.  A fond smile spread over mothers face.  Brenda smiled affectionately back.
"Well, mother, I guess it's time."
"Are you ready," asked mother?
Brenda glanced in the direction of the audience.  "Yes, I believe I am."
The two does turned and walked to the trap at the front of center stage, where two nooses waited for the two does.  A ripple of polite applause rose from the audience.   Standing on the trap next to her noose, Brenda unconciously scratched her swollen belly.  Only six months, but the stretching skin still itched occationally.  She smiled at herself; the itching wouldn't be a problem much longer.
There was a large button on the upright at Brenda's side.  When she raised her hand to it, it was just at the edge of her reach.
"This is  -" murmured Brenda.
"Yes," replied her mother.  "After you put your noose on, play with yourself until you are fully aroused.  When you are ready to climax, just push that button."
"How will I know if you're ready?"
Her mother smiled.  "Dear, I am so ready right now, that I will climax as soon as you push the button, whenever it may be."
Brenda almost chuckled in reply.  When the Culling Act had passed, it was pretty obvious that Brenda would have to go.  As an unwed pregnant teenage prey species, of course she would be picked if she hadn't volunteered first.  But mother had volunteered as well.  Partly because she wanted to accompany her daughter; partly because she was a single prey female and might be picked anyway; and partly because she fapped to auto erotic asphyxia frequently, so she was intensely aroused by being here.
Mother took one noose in her hands, and pulled it back to her muzzle.  She had a self satisfied smile on her face, as she tilted her head forward to slip the rope over her ears and around her neck.   Mother slid her hands under her hair and slipped it out of the loop, then tossed her head to settle her mane.  It was a deliciously sexy gesture.
Brenda reached up and took her own noose in her hands.  As her mother had, she pulled the loop back to her face, and pulled it over her muzzle.  Then she tilted her head forward to bring the lethal knot to the back of her head.  She reached under her hair, pulled  her hair out of the loop, and flipped her long locks to the side.
There was a noose around her neck.  Brenda had a hanging noose around her neck, and in just a few minutes it was going to choke the life out of her.  Mother had long believed that if a woman had to die, then a death by hanging was the sexiest, most exciting way to do it.  Now Brenda and her mother were going to hang, side by side, in front of an audience.  And, it felt wonderful!
Brenda slid her hands down bellow her belly, to the soft lips between her legs.  With her eyes half closed, she began to gently stroke herself.  It was embarrassing doing it in front of the audience, but it did feel good.  
As she ran her fingers over her labial lips, she could imagine all the men and women in the audience getting aroused watching her.  And she began to realize that her ability to excite the audience, was exciting her as well.  It was as if she wasn't just making love to herself; she was making love to all those other people.  She didn't need to feel embarrassed about fapping in front of all those people.  They came to watch her, and she came here so that they could watch her.  She decided she was going to make certain they enjoyed what she had to show.
She flexed her knees, and pushed forward her hips, in hopes that it would help the audience see what she was doing.  Bending forward slightly as the waist, she was able to push two fingers into her hole.   She was rapidly getting wet enough to make it easy.  With the forefinger of her other hand, she began to vigorously rub her clitoris.   The sexual urgency swelled in her like a weight settling in her hips.  
Brenda was aware of her mother at her side.   Her mother's neck encircled by the deadly noose.  Her mother's hands busy between her legs, as her mother fapped  for the audience.  Small groans of ecstacy coming from her mother's smiling muzzle.  Brenda could smell the sexual arousal rising from between her mother's legs.
She should be terrified of dying.  She should be horrified at what the noose around her neck was going to do to her.  But she could tell how thrilled her mother was.  She could sense how intensely sexual this was for her mother.  And that made it sexual for her too.  Her naked body was arousing to the audience.  Her fapping was arousing to the audience.  In a few short moments her dying struggles would be arousing to the audience.  And her awareness of the audience's response was arousing her.
Her finger rubbed her clitoris harder.  And faster.  The raw sexual sensation building in her belly began to fill her body.  The pressure built rapidly in her mind, blocking out all other thought.  The need to climax growing closer and closer.  Until the pressure grew to be too much, and the erotic excitement began to overflow.  Now!  Now!
Her hand shot out to find the button on the upright at her side.  Hitting the button let her orgasm explode out of her.  She was barely aware of a brief cry from her mother, suddenly cut off.  Her knees flew apart, and her hooves kicked.  Her back and belly muscles tensed up.  Her hands gripped at her crotch, one finger madly rubbing her clitoris.  Forcing the climax to go on and on.
She wanted to scream out.  She wanted to pant.  But nothing happened.  Her lungs were working, but no air was moving.   She was hanging!  The rope around her neck was killing her!
Her eyes shot open.  The room was swaying around her.  No, she was swinging on the rope.  She could see the crowd watching, and hear their screams of delight.  At her side her mother still had her hands between her legs.  Her mother's hips were vigorously thrusting back and forth, and that was waving her dangling legs over the open space below her feet. With a slight twist of her head, Brenda could look down past her pregnancy swollen belly, past her own dangling hoofs, to the open space beneath her.
The rope around her neck squeezed deeply into her throat.  The pressure on her lower jaw was incredible.  But it didn't really hurt.  Her lungs hurt.  They were trying to pump air, but getting nothing, and they ached with the need for fresh air.  There was a strange warmth in her twitching ears.  Her tongue felt swollen and pressed hard against the back of her mouth.  But it didn't really hurt.  She felt light headed, and that actually felt rather pleasant.  That must be what her mother sought in her erotic asphyxia play.
Brenda raised her left hand to the noose.  The rope was sunk so deeply into the fur and flesh that if she had tried she would not have been able to get a grip.  The rope that was killing her.  But at the same time, her right hand snaked back down her belly to her crotch.  She could just barely reach one finger to her clitoris again.  One finger was all it took and she began to rub again.  Began to fap again.  Began to pull that sexual arousal out again.  And, Oh yes, she was  aroused!
The sexual energy built quickly in her belly.  The light headed feeling actually helped.  The rope around her neck didn't matter.  The baby in her belly didn't matter.  Her mother fapping as she hanged to death at her side didn't matter.  The arousal of the roaring crowd didn't matter.  All that mattered was her finger on her clit.  The need to orgasm.  The need for the rapidly swelling pleasure in her groin was more important than the need for air in her lungs.
She could feel her ears burning.  She could feel her eyes tearing.  She could feel her lungs aching.  She could feel her heart pumping.  She could feel her hips thrusting.  She could feel her legs thrashing.  None of that mattered.  She could feel the excitement in her sex.  She could feel the pleasure in her clitoris.  She could feel the approaching orgasm.  Closer.  Closer.  All that mattered was that last orgasm.
The climax hit her.  And it was wonderful.
