It was a week after my high school graduation, and my parents were away. So, of course, I threw a party. Nothing big – about 10 of us, equal parts boys and girls – and a lot of alcohol and pot. I was standing in the corner by the stairs with my girlfriend, Jenn.

“Hey,” she said. “Wanna make a bet?”

“Depends,” I replied. “What is it?”

“I bet you that I’m going to fist Kelly by tomorrow morning,” she said, gesturing to a short, thin redhead currently engaged in talking to someone else.

“If I win?” I asked.

“You get to join in,” she said with a smile.

“And if I lose?”

“You have to pin her to the ground while I rape her with my fist.” This is one of the reasons I’m with Jenn – she has an evil sadistic streak. It kept our sex life fun.

“Done,” I said.

I saw movement out of the corner of my eye. It was my little sister Mandy coming down the steps. Shit, I forgot she was in her room.

“Where do you think you’re going?” I demanded.

“It sounded like fun down here, and I was wondering if I could join in,” she replied.

Jenn looked at me. “I think we could have some fun with this.”

Mandy was starting to go through her rebellious stage. In her, it manifested as a mall goth. Tons of eyeliner. Fishnet arm warmers. Black baggy pants with chains and a thick belt. Her hair matched the rest of her black outfit, although there was a little bit of blonde peeking out at the roots. At 14, she was just starting to develop sexually, so her breasts were little more than an A cup, and she rarely wore a bra.

“Alright,” Jenn said. “Let’s get you loosened up first.” She put her arm around Mandy’s shoulders and led her to the kitchen table that was serving as a bar. Jenn poured three shot glasses of tequila, and lined them up on the edge of the table. “You have to drink these.”

Mandy had never drank before, except for a glass of champagne at their cousin’s wedding. “Well, that will certainly loosen me up a bit.”

“Wait!” I yelled. “I’ve got an idea.” I ran out of the room and upstairs into our parents’ bathroom. I opened the medicine cabinet, took my mom’s bottle of Xanax, and poured one into my hand. I put the bottle back and made my way back to the kitchen. I poured a glass of water and brought it over to my sister, my hand open so she could see the pill.

“What is that?” she asked.

“Just take it. Trust me,” I answered. She downed the pill with a sip of water. “Okay, now drink the tequila,” I ordered. She made a face at the first shot. She gagged on the second. On the third, she almost spit it out, but managed to choke it down.

“How do you feel?” Jenn asked.

“Good,” said Mandy. “Really good. But wobbly.”

“Let’s do a little sobriety test. Bet you can’t walk a straight line from here to the door.” Mandy puffed up and looked determined, setting her eyes on the door, and carefully put one foot in front of the other. She wavered, trying to find her balance, on every step. Halfway across the room, she tripped over her own feet and fell to the ground, laughing.

“Good, you’re nice and drunk,” said Jenn. “That will make what’s going to happen next so much easier.” She grabbed Mandy by the arm and led her to the living room, where everyone else was. “Alright!” she yelled, pushing Mandy in front of her. Everyone went quiet and stared at the two of them. “There’s someone here who wants to party with the cool kids. But first, she has to prove she’s cool enough.”

“What do you want me to do?” asked Mandy.

“Take off your shirt,” demanded Jenn.

“But I’m not wearing anything underneath”

“I know. Do it.”

Mandy hesitated. She had never let a guy see her tits before. Hell, she’d only kissed two guys, and one of them didn’t count because he was gay. She felt a flutter in her chest and a wetness in her pussy at the thought of several guys staring at her tits. She grabbed the edges of her shirt and pulled, stretching her arms above her head to show off her tiny buds. She could see bulges in several of the guys pants, including her brother’s. “Oh wow. I did that??” she mused with a flush of pride.

“Good,” said Jenn. “Now take off your belt and hand it to me.” It took Mandy several tries to undo the buckle, but eventually she got it, pulled, and handed the belt to Jenn. Jenn folded the belt in two lengthwise and snapped it. “Now take off your pants.”

Mandy really didn’t want to. She could feel the wetness of her pussy being soaked up by her underwear. She was afraid that people would think she peed herself. “DO IT!” shouted Jenn. Mandy undid the button and the zipper and let the pants fall to the ground. She was wearing white boyshorts. There was a massive wet spot in the front, and the fabric was thin enough that you could see her pussy pushed up against it.

Mandy was humiliated, but she could tell the people around her were enjoying it. Several of the guys, myself included, had pulled out their dicks and were stroking them while staring at my little sister. Kelly and some guy were making out and rubbing each other in the corner.

“And now your panties,” Jenn ordered. Mandy didn’t hesitate this time. She pulled them down around her ankles and stepped out of them. Bending back up, she parted her legs a little to show off her pussy. She was completely bald, except for a little tuft of blonde at the top.

“You’re such a good little slut. On your knees,” Jenn ordered.

“Why?” asked Mandy. Jenn took the belt in her hand and whipped her across the ass. Mandy cried out in both pain and surprise, and stumbled forward a step.

“When you speak to me, you are to call me Mistress. Is that clear?” said Jenn.

“Yes, Mistress,” said Mandy.

“Good. Now on your knees.”

Mandy complied. She liked being someone else’s bitch. The thought of how much of a whore she was being turned her on. Her pussy dripped as she thought of being the plaything of so many people.

Jenn stood in front of my little sister. “Take off my pants,” she ordered. Mandy undid the button and let them drop, and was surprised to find that Jenn wasn’t wearing any underwear, her hairy pussy inches from her face. Jenn spread her legs a little. “Lick my pussy,” she ordered. Mandy leaned forward and stuck out her tongue, sliding it from the bottom of her Mistresses pussy to the top. Mandy could taste Jenn’s intoxicating nectar, and felt a tingle go through her own cunt. She moved a hand between her legs and started rubbing.

“Mmmmm,” Jenn moaned. She grabbed Mandy by the hair and started grinding her pussy against my sister’s face. As my sister’s strokes at her clit grew faster, Jenn’s face fucking grew more intense. She arched her back. “Oh fuck, I’m gonna cum!” She grabbed my sister’s hair and pulled her face deep into her pussy as she screamed. Right as Mandy felt Jenn’s pussy spasm, she felt like she was about to cum herself. She rubbed her clit as fast as she could. When she came, she screamed right into Jenn’s pussy. It took them both a minute to recover. Mandy knelt, panting, just like her Mistress told her to. When Jenn pulled away and turned to address us, I could see smears of my girlfriend’s pussy juice all over my little sister’s lips.

“I think we have ourselves a good little whore,” she said. “Fuck yes!” I said. There were grunts and agreements from all around the room.

“Well, since it’s our party she wants to go to, she belongs to all of us. I want to turn this whore into a grade-A cumslut. Are you up for that?”

Seeing my sister humiliated and degraded like this really turned me on. I could feel the cum rising in my balls, and I knew I wouldn’t last long.

“I want every guy here to cum on her face. Including you, big brother. I want her face to look like a glazed doughnut when we’re done. Who wants to start?”

I walked over to my kneeling slut of a sister. I looked into her eyes, which were burning with lust. “Do it, big bro,” she said. “I want to feel my brother’s cum on my face.” I rubbed myself faster, until I felt it hit. My cock twitched and my balls contracted, shooting thick streams of pearly white cum onto my sister’s cheek. She flinched, then looked shocked. She looked up at me, and a smile broke across her lips.

“Next!” Jenn yelled. As I moved aside, the other three guys at the party took up positions around her. One of them tilted her head up, and said “stick out your tongue.” She did. The first guy groaned and blew his load on her left cheek. The second came on the other cheek, and the third’s cum hit my little sister in the left eye and temple. Droplets of cum stood out like pearls against her dyed black hair.

Then, Kelly – completely naked – walks up to my sister, rubbing her clit furiously. She angled her cunt towards my sisters face and, with an ear-shattering scream, squirted all over my sister’s face.

Mandy was in bliss. She loved the taste of cum and pussy juice on her tongue and the feel of it on her skin. She loved being a sex object, just something for people to fuck. She felt sexy, knowing that she’d gotten so many guys – and even a girl! – to cum for her.

“Aww, poor little cumslut,” said Jenn. “It looks like you’ve got cum all over your face. How about I help you wash that off?”

Jenn stood in front of my Mandy’s face and spread her pussy lips. I don’t know what I was expecting, but Jenn started peeing on my sister’s face. It flowed down her neck and caressed her tiny 14-year-old tits. “Open your mouth,” she said. She wiggled to get her stream to hit the back of my sister’s throat. My sister choked and tried to pull away. Jenn grabbed her by the hair and forced her face into the stream. “Drink it,” Jenn ordered.

Mandy was lightheaded. She never thought she’d be humiliated and used like this! Just a worthless little slut. Her pussy throbbed and dripped, and her hand rubbed her clit even faster.

“Drink it!” Jenn demanded. Mandy opened her mouth and let Jenn’s pee fill it, then took a gulp. It tasted salty. She liked it.

Jenn’s bladder ran out, and she took a step back and admired her work. “I’m guessing you’re a virgin?”

“Yes, Mistress,” said my sister.

“Well, that’s about to change. And you know who’s going to be your first fuck? Your brother.”

Mandy loved this idea. It was so dirty and wrong. Imagine if their parents found out!

“Mmmm, yes please, Mistress.”

“Come here, slut,” Jenn said as she led my sister over to the coffee table. She lay Mandy down on the table, making sure her butt was hanging off a bit. I knelt down, and her pussy was lined up perfectly with my cock. I pressed my dick against my 14-year-old sister’s tight cunt, which was dripping with juices. I pushed my cock into her with one slow thrust. She screamed as I broke her hymen, but as I slowly pumped in and out of her, her moans of pain turned to moans of pleasure. As I gained speed, two guys came up to either side of her. My sister reached out and started jerking their cocks. As I pumped faster and faster, my girlfriend got up onto the table and positioned herself over my sister’s face. My sister stuck out her tongue, and Jenn lowered herself onto Mandy’s face. Jenn put her hands around my sister’s slender throat and put her weight onto it.

Mandy felt her airway cut off, and panicked. She couldn’t breathe! She felt Jenn’s pussy rubbing against her face, and she started to black out. Her whole body started tingling, and her brother’s cock pounding in and out of her tight virgin cunt felt absolutely amazing. Suddenly, she had her breath back, but that only lasted a moment until Jenn’s hands choked her again, this time harder. She felt Jenn’s thighs clamp around her ears, and she heard a muffled, drawn-out scream as Jenn’s pussy twitched and dripped on her face. Mandy could feel Jenn’s orgasm pass through her as she started to black out, and was aware of her back arching and her pussy spasming and gripping her brother’s cock.

After my sister came, she passed out. The two guys at her side came on her chest at pretty much the same time, covering her tits with sticky fluid. My sister was completely limp. I grabbed her hips and kept fucking my unconscious 14-year-old sister.

“Don’t cum in her yet,” said Jenn. “I have something special planned. Go sit on the couch.”

I did. Jenn stood over my sister and patted her face. “Wake up, honey. We still have more.” Mandy didn’t budge. Jenn slapped her across the face hard. “Wake up, bitch!” Mandy stirred and looked up at Jenn, and managed a weak “yes, master.”

“Kelly!”, Jenn demanded.

“Yeah?” said Kelly.

“You’ve got a lot of pussy juice. Ride my boyfriend until his cock is nice and slippery.” Kelly stepped over to the couch and straddled my lap. She reached down and guided my cock into her dripping pussy. Wow, Jenn wasn’t kidding. Kelly was absolutely soaked, with pussy juice flowing down her thighs. I only got to pump into Kelly a couple of times before Jenn said “Enough. He’s lubed up enough.” Kelly reluctantly dismounted and went back to watching while stroking her clit.

Jenn dragged my sister over to the couch. “Lay back on your brother’s chest and lift your knees to your tits.” She lay on top of me, and I put my arms around her. She grabbed her knees to her chest, exposing her tight virgin asshole to Jenn.

Holy shit, Mandy thought. My brother’s going to fuck my ass! That’s so fucking dirty, I’m such a little slut!

Jenn lined up my cock with my little sister’s asshole. I started pushing into her, until the head of my cock just slipped into my dirty little whore of a sister’s ass. She squealed in pain, and moaned as I slowly thrust the rest of my cock deep into my sister’s ass. I moved in and out, gently at first, but then growing faster and faster until I was pounding my sister’s tight virgin asshole.

My sister still had her knees to her chest, exposing her pussy to everyone else in the room. One of the guys walked over and thrust his cock into her pussy. I could feel the girth of his cock squeezing against the anus, making it grip my cock even tighter.

Mandy didn’t think it was physically possible to take two cocks at once until she had them inside her. She saw stars in her vision and came harder than she thought was possible. She started going numb, and her euphoria faded to black.

We both kept fucking her when she went limp. Gang raping my unconscious 14-year-old sister was something I never knew I wanted until now. My partner let out a groan and came inside my sister. His cum leaked out of her pussy and down to her asshole. I kept reaming my unconscious sister’s asshole. I bounced her up and down on my lap, her arms lolling about. As my orgasm started to build, I thought about how much we had used her. She belongs to all of us. She was so humiliated, and she loved every second of it. She loved being a sex toy. She just wanted to be dominated and used. Filthy cumslut. I could feel my orgasm rising through my cock, and with a scream, I shot what felt like gallons of cum into my 14-year-old sister’s virgin asshole.

I lifted her off my chest and lay her down on the couch. I surveyed what we had done. There was cum all over her face and chest, and it was dripping out of both holes. Jenn was next to me with a camera. I spread her legs and put her arms above her head while Jenn took pictures off my little whore sister to show to everyone.

I patted her cheek a little. She stirred, and looked up at me.

“Welcome to the party,” I said.

“Thanks, big brother.”
