Billy & Mandy’s Halloween Horror Hunt 2
“So what happened?”
“Billy took a bite out of Eris’ Apple of Discord.” Grim says. “I think him and Nergal Jr. are rampaging through town. So far, over 9-dozen women have experienced Death by Orgasms. The others have been paralyzed from the waist down.”
“Figures that Billy’s dick would get him into trouble.” Mandy says. “Nergal Jr. has to be the mastermind behind this. Where’s Eris? She can hone in on Chaos and give us a bead on their location.”
“Unfortunately the woman’s gone off to watch them create havoc from up close.” Grim replies.
“Then we’ll need to find a lead.” Mandy tells him.
“I know where you can find the losers.”
The two turn around to see Mindy standing there…or rather her spirit. Grim’s eyes widen in shock, as he can’t believe his eyes. Mandy keeps the same look. “Let me guess.” Mandy says. “You decided to have fun with Billy while I was gone.”
“NOOO!” Mindy replies, feeling offended. “It was that nerd Nergal who did this to me. Him and those damn tentacles of his! He made me have 27 consecutive orgasms, and put me in this position.” She turns to Grim. “You better find a way to fix this, Bonehead!”
“He’ll fix it, when I tell him to.” Mandy says, as she stands up and walks over to Mindy. “As for now, you can tell me where Nergal & Billy are.”
“Those two ran off from the school once they were done.” She says. “They said something about meeting some Goddess and setting her straight.”
“Eris!” Grim says. “Oh, that’s just perfect. Not only does that nincompoop keep me busy by killing on Halloween, but now he wants to bone my wife.”
“Quit whining and just find out their location, Grim.” Mandy orders. Grim taps his scythe on the floor three times, and an image appears on the blade. It shows Eris walking through Endsville Mall towards the movie theatre. It also shows Billy & Nergal Jr. hiding in the food court behind separate newspapers, watching her every move.
“There. They’re at the Mall. I can…” Grim gets interrupted when his scythe starts to vibrate and make a beeping noise. “Oh, just great. I got another dozen to pick up cause of those guys. You’re gonna have to get to them on your own.”
BOOF!!! The Reaper disappears in a black mushroom cloud, leaving Mandy & Mindy’s soul alone. “So what’re we gonna do now?” Mindy asks.
Mandy turns and walks to the rear of the plane, stopping in front of a door. She turns her head and looks at Mindy. “How fast can you fly?” She opens the door to reveal a brand spanking new Kawasaki Racing Motorcycle. She walks in and hops on top, before putting on her helmet. She then turns around as a hidden door slowly slides open behind her. The plane has now hit the runway, and is rolling to a stop. Mandy hits reverse on her Cycle and rolls backwards out of the plane. A split second before she hits the pavement, she accelerates forward and goes speeding down the runway. A moment later, Mindy joins her by her side flying at full speed as they jet towards Endsville, and the Mall.
Meanwhile, At The Mall…
Eris opens a door and walks into the Movie Theater that’s showing ‘Saw’. She walks in right at the gruesome part, when someone gets mutilated, and begins to laugh loudly. “Oh, this is so hilarious.” She says. “I love that little puppet.” The Theater is surprisingly empty, which makes it all the more eerie. She stands in the middle of the aisle and folds her arms over her chest, as she starts to look upset. “Hmmph! Those two aren’t even here.” She says. “That’s the last time I trust a news report from Dan Rather.”
“Hello, Eris.”
She quickly darts her head around to see Nergal standing behind her. “You know, I really must hand it to you.” Eris says. “Getting that dimwit Billy to take a bite out of my apple, then go rampaging throughout the town was a stroke of genius. Even though it was without my permission.”
“Oh, I’m sorry, Eris.” Nergal says. “Let me make it up to you.”
Dozens of tentacles shoot out from behind him and barrel towards Eris. But Eris just waves her hand, causing all of them to fall harmlessly to the floor. “Oh, please. I use to smack your father around for fun.” She tells him. “Do you really think you’re more powerful?”
“No, I don’t.” He replies with a smirk. “That’s why I’m just a distraction.”
As soon as those words leave his mouth, a hulking Billy slowly rises up behind Eris. She senses him and turns, but it quickly pinned down on the floor. Billy has a mad, maniacal grin on his face, as his eyes roam all over her body. She immediately knows what he has planned. “NO! You can’t do this.” She says. “I’m a Goddess!”
“I’ll leave you two lovebirds alone.” Nergal says with a smirk, as he turns and walks out of the theater. He walks through the lobby with his hands behind his back & his head held high. So far he has caused more mayhem & bedlam to Endsville than he ever could’ve dreamed, and he has plans for much more. But he sees his plans falling in jeopardy as he looks through the lobby’s glass doors and sees the one woman who can shut him down…Mandy.
“Oh, dear.” He says to himself. “I forgot about Billy’s friend. She could ruin my whole plan. Unless I deal with the situation.”
Outside of the Theater portion of the Mall, Mandy hops off of her bike and takes off her helmet. She looks around for anything suspicious before starting towards the door. “The news report said that the two were seen here last.”
“Do you really think you can trust Dan Rather?” Mindy asks, floating down to her side from above.
“No, but right now I don’t have another option.” She walks through the glass doors and into the lobby of the Theater. The lobby is deathly quiet & empty. No sign of life whatsoever, despite the cash registers & popcorn machines that are still active. She slowly walks through, looking around for any signs of ambush. Mindy sees one, as she notices a black tentacle trying to stay hidden behind the Candy Counter.
“MANDY! TO YOUR LEFT!!!”
The tentacle shoots out like a bullet aimed dead at Mandy, but she stops it just inches from her mouth, gripping it tightly. Nergal then stands up from behind the counter and reveals himself. “Nergal Jr. You must have some balls to pull of this plan.” Mandy says.
“Why thank you.” Nergal says, taking it as a compliment. “And I can’t let you get in my way.”
“What are you planning to do?” She asks, struggling to keep the tentacle in her grasp.
“I’m gonna have you join your friend Mindy in the afterlife.” He says with an evil smirk. “I wonder how many orgasms it’ll take for you to get there?” And with that, dozens of tentacles emerge from behind his back. Mindy stands there horrified as the memories come back to her about her own death. Mandy doesn’t look intimidated at all, even when Nergal commands them to swarm Mandy & attack.
Back in the Theater…
Eris is still trapped on the floor by Billy, whose leans in closer to her. She can feel his monster Cock rubbing against her through his pants. In desperation, she tries to crawl for the door. But Billy grabs hold of her by the hips, before ripping her skirt clean off, showing that she’s not even wearing any underwear. He becomes even more aroused by this, and pulls his giant Rod out into the open.
“Crap! I knew I should’ve worn underwear today.” Eris says. She can feel the head of his Cock rub against her love lips. Part of her is terrified about taking in so much, yet the other part wants it to happen so badly. And she becomes wetter by the second thinking of it. Billy looks down and grins, not wanting to wait any longer. He thrusts himself deep into Eris’ pussy, making her cringe and scream in agony & pleasure.
“AAAAAAAAAAAAAAGHHHHHHHHHH!!!!!”
He pushes deep into her, making sure her pussy takes in his entire Rod. “Dear God in heaven.” She thinks. “Please let me survive this. And I promise to only make chaos during the weekends.”
“PUSSY TIGHT!!!” Billy yells, as he starts to pound her love box without mercy. Her entire body is pushed forward with each time he pumps into her pussy. Eris grits her teeth as she tries to hold herself up. His strokes are making her weak in the knees, and her arms aren’t holding up well either. Suddenly, Billy pulls her upright and starts roughly fondling her round melons as he drives into her over & over. She closes her eyes and starts grunting & moaning loudly, feeling waves of ecstasy wash over her with each thrust. She feels her entire body going limp with pleasure, as she desperately tries to think of a way out of this.
“The Apple of Discord.” She thinks. “I can summon it here…and stop Billy. But…But…Oh god he’s so good!”
Her grunts become louder as her breathing becomes heavier. She feels herself about to hit her limit harder than she ever has. Billy’s not helping as he picks up the pace, and doesn’t stop until she screams.
“IN THE NAME OF CHAOS…I’M GONNA CUUUUUUUUUUUUUUUMMM!!!!!!”
She squirts her love juices out all over Billy’s Cock, as he comes to a stop. She falls to the floor, feeling spent & barely able to move. She lifts her head up and snaps her fingers, causing the Golden Apple of Discord to appear right in front of him. But as she reaches out for it, she hears some horrifying words.
“BILLY WANTS ASS!!!”
Those words are followed by his trademark giggle, as Eris’ face turns pale white. “Oh, dear sweet lord in heave Jesus no.” She tries to claw her way to the Apple, but Billy grabs firm hold of her hips. He leans in and injects her ass with his massive Rod, causing Eris to lose her breath for several moments. She buries her head in her arms as Billy punishes her ass repeatedly. The sound of skin smacking skin fills the entire Theater. Billy is drilling her asshole like a jackhammer now, as he grins happily all the while. He’s now going at a blinding pace, so fast that his hips are a blur. Eris, who’s barely holding on to her sanity now, can’t even let out a scream as she hits her 2nd orgasm. Billy pulls out her and looks down at his handiwork. Her pussy is soaked and her asshole is gaping. He quickly loses interest in her and decides to explore some more.
“BILLY WANT MORE PUSSY!!!” He leaps up and through a nearby wall, creating a giant hole in his impression, as he goes off through Endsville, looking for more women to ravage.
Back in the Lobby…
Nergal finds himself completely exhausted now. His power is completely drained, as he drops down to his knees in defeat. His plan was to rape Mandy to death with his tentacles. But he greatly underestimated her lasting power. She didn’t even have one orgasm. “How…how could this be?” He asks himself. “It’s not possible.” His tentacles release Mandy and retreat back into him, as Mandy lands on her feet.
“You call that Tentacle Rape?” She says. “I call it pathetic.” She walks over to him and grabs him by his collar, pulling him close to her so she can look him in the eye. “Now that the foreplay’s over, where’s Billy?”
“No…I’ll never tell you.” He replies.
“Well then, maybe we should go for Round 2.” She reaches behind him and grabs one of his tentacles, ready to put it back inside of her. Nergal panics at the very thought.
“OK! OK! He’s in the Saw Theater.” He tells her. “Just please, no more.”
Mandy tosses him back to the floor and walks over to the Theater doors. She kicks them open, expecting to see Billy there. What she finds is Eris lying on the ground, unable to move. “I…I can’t move my legs.” She says.
Mandy looks down at her and immediately recognizes the handiwork. “Well, Billy was definitely here.” She sees Eris pointing at the Apple of Discord, and walks over to pick it up.
“You…have to use…the Apple, Mandy.” Eris tells her. “Make him…take another bite. And he’ll…revert…to normal.” She crawls up her leg and looks her in the eye. “Help us, Mandy…you’re our only hope!”
“Alright, that’s enough of the Star Wars jokes.” Mandy says, swatting Eris off of her. As Mindy joins her, a black Mushroom cloud appears in the room, signaling Grim’s entrance. He walks out of the cloud and sees the damage that’s been done.
“Oh, great. Now Billy’s fucked my wife.” He says,
“The way he’s going, he’ll fuck every wife in Endsville.” Mandy says. “We’ve gotta put a stop to this.”
“Well, you’ve got the apple.” Grim says. “But you’ll need a costume to use that thing to its full power. It is Halloween after all.”
BOOF!!! Grim uses his powers to transport himself, Mandy & Mindy from the Theater to the only open Costume Shop in Endsville. As they look around, they see that the store is completely empty of stock. Every costume has been bought out, every costume…except one. Grim points out the costume on a hanger in the corner, and it makes Mandy cringe with fear once she sees which on it is.
“My god.” She says. “It would have to be that costume.”
“So you still got that thing about the—.”
Mandy gives Grim a backhand, shutting him up and causing his skull to fly off of his body. “It’s not a thing, OK? It’s not a thing!”
“Well regardless, it’s the only costume they got left.” Grim says, picking his head up from off the floor. “It’s either that…or the other way.” He holds up his scythe, showing that he means his way is the other way. Mandy starts thinking it over for a while, before she comes to a decision.
“I already put too much Lackey Training into Billy to let it go to waste.” She sighs. “Point me to the changing room.”
She snatches the costume from off the hanger and storms angrily into the dressing room. Grim walks over to the counter and pays for the costume, pulling out his wallet. “Do you accept ‘Underworld Express’?” He asks.
“I need to see your ID.” The Clerk tells him.
“But…But…I’m the Grim Reaper!” He counters. “I was around when your Great-Great-Great-Great-Great-Great-Great-Great-Great-Great-Great Grand Pappy was pulling himself out of the mud.”
“Just pay the man, Grim.”
Mindy & Grim turn back to the changing room to see Mandy in her costume…dressed as a Figure Skater. There is a long, awkward silence as they continue to stare at Mandy. After a few minutes, Mindy finally breaks the silence by laughing hysterically.
“Oh, God! Even dead, this is the funniest thing I’ve ever witnessed!” She falls to the ground and starts rolling around, holding her gut while still laughing. Mandy just ignores her and tries to walk out of the store. But with the first step in her ice skates, she stumbles and falls flat on her face. Mindy starts to laugh even louder after seeing that. “If…If I wasn’t dead, I’d probably laugh myself there!”
Grim walks over and helps Mandy to her feet. “You see, you gotta shift your wait and…”
“Just shut up & find Billy.” Mandy says coldly. Grim taps his scythe against the ground twice, and an image of Billy running through the Endsville Graveyard appears on the blade.
“He’s at the Graveyard. Let’s go!”
BOOF!!! Grim transports everyone to the Graveyard, right in front of Billy’s path to be exact. As he rumbles closer to them, Nergal Jr. pops up from a nearby grave to face them. “You won’t stop, Billy.” He says. “The only thing he understands is sex. He won’t listen to anyone.”
Mandy just scoffs and turns towards Billy. He gets closer, and closer, until Mandy puts up her hand and stares him down. “BILLY, STOP!!!” Billy puts his brakes on, stopping just mere inches in front of Mandy. He stands there, huffing and growling, looking like a predator ready to pounce. Mandy approaches him and looks him in the eye. “Billy, I’m ordering you to snap out off it right now.”
“M-M-M…M-Mandy?” Billy starts showing signs of reverting back, but they quickly fade and he becomes the Monster again. “NO! BILLY FUCK!!!”
Nergal Jr. begins to laugh sinisterly, thinking that Mandy has failed. “I told you, the only thing he understands is sex. There’s no way you can get through to him.”
Mandy looks at Nergal Jr., then looks at Billy, and comes to a conclusion. “You know, I knew at one point in my life I’d be having sex in a Graveyard.” She pulls Billy down to eye level and kisses him passionately, shocking everyone in the vicinity. Her tongue runs into Billy’s mouth without delay, as she ventures her hand into his pants. She begins to stroke his Cock, trying to make it come to peak hardness. The two end up falling onto a freshly made grave, with Mandy landing on top of Billy. She keeps stroking his manhood as she breaks the kiss. “The things I do to make sure my Evil Empire stays intact.”
“Wow.” Grim says, looking shocked. “She’s actually really gonna have sex with him in this graveyard.”
“Yeah, didn’t expect that.” Nergal adds, before finally realizing his plan is in jeopardy. “Oh no, I gotta stop them.”
He tries to run over to them, but Grim’s scythe blocks the way. “Not gonna happen, tentacle boy.” He says.
“Fine. Bring it, you old bag of bones.” Nergal Jr. jumps back and lets his tentacles fly. But Grim begins to slice each of them down, laughing evilly all the while. Mindy stays on the sidelines, cheering them on.
“GO, NERGAL!!!” Grim looks at her in disbelief as she realizes what she just said. “Uh, I mean go Grim?”
This gives Nergal Jr. the opening he wanted, and he uses it to knock Grim’s head off of his body. “Oh, come on! How many times am I gonna get my block knocked off in this story?”
Meanwhile Mandy, still working over Billy, finds things are getting tougher for her. “I’m not gonna get him off with a blowjob.” She says to herself. “I’d need to be an Anaconda to fit that thing in my mouth. There’s only one way to go.” She stops stroking his Cock and backs herself up into a tombstone. She pulls her panties off and tosses them aside as she sits spread eagle, inviting Billy over to her. “Alright, Billy. You wanna fuck? Come & get it.”
“BILLY FUCK!!!” He almost pounces on top of her as he injects her with his Rod. She lets out a loud groan of pain, never having anything that big inside of her. As he begins his strokes, Mandy remembers the Golden Apple of Discord.
“Damn! I forgot the apple!” She thinks. “If I don’t get to it, he’ll just keep fucking me forever.”
She tries to grab it, but it’s just out of reach. And the sensation of getting her love box plowed into starts to overcome her. Billy’s working her over harder than he did Ms. Butterbean & Eris, and doesn’t look like he’s gonna slow down. Mandy feels herself becoming lost in the moment, and tries to fight back. “I…have to fight it!” She thinks. “Must…reach…apple before…GOTDAMN, his cock feels good.”
She wraps her legs around him and just holds on, enjoying this moment more than she has any other moment with Billy. He’s now letting into her balls deep, each stroke causing the tombstone they’re up against to rock & lean more. Mandy is grunting & moaning loudly, completely lost in the moment. But she snaps out of it when she feels herself coming to her limit. “I…gotta put an end to this.”
She grabs the back of Billy’s head, pulls him close and kisses him again, more passionately than she ever has. He’s caught off guard by this and slows down his strokes. Mandy takes advantage and reaches for the Apple of Discord again. She grabs it, breaks the kiss and shoves the apple into Billy’s mouth. He instinctively takes a bite out of it, then swallows the bite. A moment later, he goes through a transformation, and shoots his load deep inside of Mandy, who also hits her orgasm hard. The bright purple aura surrounds Billy again, like before, and turns him back to normal.
“Magic…Banana…needs sugar.” He says, before collapsing on top of her. Mandy breathes a sigh of relief as she now notices Nergal Jr. & Grim battling through the graveyard. The battle looks to be deadlocked, until the very earth beneath them opens up, and Nergal Sr. slowly rises up from the fiery pits, followed by Eris, who’s now in a wheelchair.
“WHAT IS THE MEANING OF THIS??” Nergal yells.
“Father! What are you doing here?” Nergal Jr. asks.
“I brought him here.” Eris says. “And I told him about everything that you’ve done ever since you got up here.”
Nergal slowly approaches his son with a look of pure rage in his eyes. “You mean to tell me that you came up to the surface, tricked a simpleton into taking a bite out of the Apple of Discord, then rampaged throughout town, creating havoc & chaos by having Sexual Intercourse with Women UNTIL THEY MET THEIR UNTIMELY DEMISE???”
Nergal Jr. lowers his head and nods yes, feeling that he’s shamed his father. He expects to be punished severely, but is surprised when he hugs him. “I’m so proud of you, boy.” Nergal says, grinning from ear to ear. “To think, my own son causing such anarchy. And on Halloween, too! I think this deserves a raise in your allowance.”
Nergal Jr. smiles brightly at his father. “Thanks, dad!” They continue sharing their father-son moment, until Mindy interrupts it.
“Hey! If anybody hasn’t noticed, I’M STILL A FREAKING GHOST HERE!!!”
“Oh, my bad.” Grim says, picking his head up off the ground. He reattaches it to his body and waves the blade of his scythe through Mindy, bringing her back to life, flesh & bones.
“My body, it’s back!” She says. “I’m not some loser ghost anymore!”
“Come on, son.” Nergal says. “Let’s go home. On the way, you can tell me how you took down the Goddess of Chaos.” Nergal Jr. goes to follow his father when Mindy grabs his arm. She grins at him and slips a business card into his pocket.
“I get off at 8pm tomorrow.” She whispers. “Meet me at my place, and bring the tentacles.” She kisses him on the cheek & winks at him, as Nergal just blushes & smiles. He then follows his father into the underworld as the opening made in the earth closes shut. Grim notices Mandy still on the ground, with Billy lying on top of her, and walks over to them.
“Need help getting up?” He asks.
“No. I’m just gonna stay here for a while.” She says.
“Of course you are.” He turns and walks back over to Eris to check on her & take her home. Mindy follows after them, while Billy finally comes to.
“Mandy! I had the weirdest dream.” He says. “I was Bruce Banner, and candy was raining from the sky, and there was this Golden Magic Banana who kept singing about Peanut Butter & Jelly.” He recognizes the look in Mandy’s eyes and realizes that things aren’t gonna be good. “Uh, I’m in trouble, ain’t I?”
“I’ll fill you in, later.” Mandy says. “But as punishment, for the next 6 months you will only use your tongue to pleasure. Am I understood?” He nods his head solemnly. “Good. Now get some sleep.” Billy does just that, dropping himself back down on top of Mandy. As he snores and drools all over her, Mandy just smiles.
“I love you too, Billy.”
