Friday October 31, 2025
I couldn’t wait for the Halloween party at the Delta Tau Chi Sorority house. My only class for the day had been a morning bio lab, but those three hours seemed to drag on forever. Somehow, Josh and Derek managed to enjoy the labs. I was on edge even after the lab, all the way until the time finally arrived to dress for the party.
Returning to the dorm with Marcia resulted in another argument about my lack of organization. Seriously, who makes their bed every day? And that bra was clean. Probably. The white powder? That could have been cocaine or something, but it wasn’t. It was from when I was eating powdered donuts I’d gotten from the vending machine. They were delicious!
Yelling led to a playful pillow fight, which quickly turned to kissing. Then we forgot all about the argument and the party as clothes came off and we got into Marcia’s perfectly-made bed. That was how I found myself with my head between her thighs and my tongue in her tasty twat.
“Oh my God, fuck!” Marcia cursed passionately. “Right there, right there!”
Marcia’s right leg started shaking as her voice went up an octave. Her hands held my head, nails digging into my scalp as she panted and moaned. I pushed two fingers into her wet box as I sucked on her clit. My other hand reached up to play with her tits. Her back arched when I tugged on her nipple.
“Oh, oh! Don’t stop! Please, don’t stop!” Marcia begged as I tongued her clit. “Oh! I’m, ah, I’m cumming!”
I eagerly swallowed Marcia’s pussy juice before kissing up her body and shoving my tongue in her mouth. Our limbs were entwined, our tits squished together as we giggled and rolled around in bed. Marcia ended up on top, her fingers dancing along my bare side as we made out passionately.
One of Marcia’s tits slid between my bigger ones while she was fingering me. Then we moved again. The petite, quiet girl adjusted herself over me so we could rub our pussies together. I grabbed her ass as we started tribbing, making passionate love to each other until we climaxed together.
“Oh hey,” I began as we started cuddling and enjoying the afterglow, “we’re gonna be late to the party.”
“What?” Marcia gasped, attempting to sit up.
“Nope!” I laughed, pulling her back down and shoving her face in my boobs. “It’s okay, kiss the titties.”
“Mmph, mm!” Marcia consented to kiss my boobs a few times before slipping out of my grasp. “Ashley, we have to get ready! And you have to spend tomorrow cleaning up this pigsty!”
“Are you eighteen or forty?” I rolled my eyes as she got out of bed. Then I was distracted by her boobs flopping around as she hunted for her clothes.
Marcia gestured around the room before planting her hands on her hips. “It’s a fucking disaster in here!”
“You’re cute when you swear,” I giggled. “And fine, I’ll organize a bit tomorrow. But tonight? Tonight I intend to find a place to get fucked by my boyfriend every which way.”
“You do that,” Marcia grumbled as she grabbed her underwear.
“Someone could use some dick,” I commented, sitting up.
Marcia froze for a second while pulling up her panties. “Uh, no. There’s no one...”
“Call up Kwan for a roll in the hay,” I suggested.
“We’re friends,” she countered as she put her bra on.
“Derek? Josh’s roommate’s a virgin,” I reminded her, waggling my eyebrows. “My hot Slut-sister could start a collection of boy-cherries.”
“Boys don’t have cherries,” she scoffed. “Now hurry up and get dressed!”
“Matt? Your bio partner?” I suggested. “Oh! Text Shawn. He’s a virgin. Hell, we’ll find you a room, you can open those legs and make a few boys into men.”
“Put some fucking clothes on!” Marcia growled.
Okay, that curse wasn’t as cute.
Twenty minutes later we were both dressed for the party. I stared at Marcia. She stared back.
“That’s it?” I asked.
She looked down at herself. “What?”
I gestured at the short girl. Black leggings, a tight, black long-sleeved shirt, and a pair of black sneakers. Her dark hair hung loose around her shoulders instead of being pulled back, which I supposed was different. She had a tail, and on top of her head was a pair of black cat ears.
“That,” I said.
“What’s wrong with it?” Marcia asked.
“Everything!”
“There’s nothing wrong with it,” she insisted.
“It’s Halloween! You wore that shirt last week!” I exclaimed.
“I washed it,” Marcia rolled her eyes. “Unlike you, I know how to do laundry.”
Marcia turned back toward the mirror above her dresser and adjusted her cat ears.
“That’s not the point,” I sighed in exasperation. “The point is that you already owned all that except the ears and tail.”
“So?” she shrugged. “It’s a costume; I’m a cat. A black cat. Meow!” Marcia made little clawing motions with her hands.
“Oh, the ‘meow’ changes everything,” I snorted.
“Exactly,” she smiled at herself in the mirror. “It’s Halloween, not ‘Dress-Like-A-Whore Day.’”
“You literally just defined Halloween,” I giggled. “It’s about letting loose! Having fun!”
“And I can do that in my adorable cat costume,” Marcia insisted.
“Fine, but be prepared for lots of T and A hanging out tonight,” I smirked.
My outfit was a sleeveless red dress that clung to my body like a second skin. It fell to mid-thigh and pressed my big tits together in what should be award-winning cleavage. I’d added black heels, a thin black choker, a red tail, and a pair of little red horns. Similar to Marcia? Maybe. But mine was hot and slutty. The way Halloween should be.
I was also wearing red eyeshadow, dark eyeliner, and deep red lipstick. I’d even put glitter along my cheeks. Marcia could have at least added whiskers and a nose. And maybe gone for a low-cut top. Sometimes I wondered how we became friends; then I remembered how long we’d been in each other’s lives, that we’d do anything for each other.
Marcia turned away from the mirror. “What are you supposed to be?”
“Isn’t it obvious?” I asked as I went through my makeup.
She pointed at my head. “Ashley with horns?”
“Fuck you,” I growled while she laughed. “You knew exactly what I was.”
“I did,” she nodded happily.
“Bitch.” I grunted as I extracted my dark eyeliner.
“You started it!” Marcia insisted.
“I’m the devil,” I declared with a curtsy. “The glamorous devil.”
I then made Marcia hold still while I gave her a dark dot on the tip of her nose and three lines on each cheek for whiskers. Then I called my sister. We talked for a few minutes while Marcia studied. Melissa was still a little cold with me, but things were getting better. Slowly.
“What’s the difference between the devil and the glamorous devil?” Marcia asked when I ended the call.
“Tits.”
“Of course,” she scoffed.
“Hey, it’s the last day of pledge week,” I pointed out. “I need to look good!”
“You’ll find out if they accept you tonight, right?” Marcia questioned.
“That’s right!” I grinned. “I’m a tall blonde with big boobs who likes to party; they’d be crazy not to take me.”
Before Marcia could respond there was a knock at the door.
“That better be someone in an actual costume,” I grumbled.
Marcia looked down at herself. “I am in an actual costume!”
I crossed the room and opened the door, coming face to face with Kayla.
I smiled. “Oh, thank God.”
“What?” Kayla frowned.
“You tried.”
Kayla’s dress was pale blue, short and shimmery, with a sheer layer over the skirt that caught the light whenever she moved. The dress had thick shoulder straps and a scoop-neck that pressed her boobs together. Glitter sparkled around her green eyes, and a pair of translucent wings rose from her back. Tiny flowers had been worked into her dark hair. She even had a little wand.
“What’s that supposed to mean?” Kayla asked.
“It means you look like a fairy,” I explained.
Kayla gave me a confused look. “I am a fairy?”
“Exactly. I knew right away,” I nodded in approval. “Effort and cleavage, that’s all I’m asking for.”
“I knew I was a cat immediately,” Marcia said from behind us.
“You stay out of this!” I called over my shoulder.
Kayla peered around me, her eyes landing on Marcia. “Hi, Marcia. You look nice.”
“Thank you,” Marcia smiled happily.
“She doesn’t mean it, she’s just being polite,” I argued.
“Anyway, where’s Lexi?” Marcia asked loudly, changing the subject.
Kayla’s smile broadened. “Peeing.”
“Why are you smiling like that?” Marcia frowned.
“No reason,” Kayla laughed lightly.
“What’s her costume?” I asked suspiciously.
“Oh, you’ll see,” Kayla erupted into a fit of giggles.
“I don’t get it,” Marcia said.
“I think we’re ab-”
“Fuck!” Lexi declared, appearing as if summoned.
The redhead wore a short white dress that hugged her before flaring slightly at the hips. White feathery wings rose behind her shoulders, softer than Kayla’s fairy wings. Her auburn hair fell in loose curls, and there was a thin gold halo above her head. She was an angel. A slutty, redheaded angel.
That wasn’t the problem.
“We look like we coordinated costumes!” Lexi growled.
Marcia started giggling right along with Kayla, both traitors bending as they struggled to contain their mirth.
“We really fucking do,” I admitted with a sigh.
“We could say we did,” Lexi suggested.
“I guess we have to,” I crossed my arms. “What business do you have wearing white anyway?”
“Really? From you, whore?” Lexi snapped while Marcia and Kayla continued laughing at me.
“If we went with a group costume like I wanted we wouldn’t be having this problem,” Kayla reasoned.
“And we agreed we couldn’t do that without all the sluts,” Marcia pointed out. “Hazel refused to come.”
“Yeah, she made some comment about not needing a costume; people would just assume she was going as a whale,” Lexi rolled her eyes.
“Whatever, her loss,” I shook my head and held up my phones. “Pictures!”
“We’re already running late,” Marcia said. “We can take pictures at the party.”
“It’ll be hard to get a group picture with just the four of us,” I said. “Just a few, then we’ll go to the sorority house.”

“No,” Scarlett said the moment she saw me outside the sorority house. “Just, no.”
“What?” I frowned.
“No,” the redhead repeated, making Tasha laugh.
I looked down at myself. Blue jeans, plaid shirt, cowboy boots. I also had on a brown vest and a cowboy hat. A cowboy was the perfect costume choice for a football player in good shape. I really didn’t see the problem; there was nothing wrong with my costume. I thought I looked great.
“What’s wrong with this?” I asked.
Scarlett gestured at me with one hand. “You dressed like yourself and bought a hat.”
“When do I ever wear cowboy boots?” I challenged. “I’m going as a cowboy.”
“You’re from California.”
“California has cowboys,” I countered.
“Not you.”
“How do you know?” I questioned.
“Have you ever been on a horse?” Scarlett asked.
“No, but I have ridden more than my share of wild fillies,” I grinned.
“Asshole,” Scarlett snorted.
Tasha blushed bright red and made herself look busy by adjusting the brim of her pointed black hat.
We continued up the sidewalk toward the sorority house. I glanced at Scarlett’s costume. “It’s not like you’ve ever turned into a bat.”
Scarlett laughed in response as her black cape fluttered around her thighs. She was also wearing black boots and a black dress. Her red hair fell over one shoulder and a thin streak of fake blood ran from the corner of her mouth. She smiled, revealing fake fangs as she made a motion toward me as if about to bite me.
“Maybe not, but I’ve nibbled on a few necks,” Scarlett smirked.
“These jokes are terrible,” Tasha laughed. “Now are you going to comment on me never casting any spells?”
In addition to her pointed hat, Tasha was wearing a fitted black dress. The first dress I’d ever seen her in. It stopped above her knees, with sheer sleeves and dark green embroidery around the cuffs and neckline. A silver pendant hung around her neck. It was amazing; Tasha had actual curves. The outfit was conservative, but it was still a lot more revealing than anything else I’d ever seen her wear.
“Nah,” I shook my head, “you look great, Tasha.”
“Thank you,” Tasha blushed.
“What the hell?!” Scarlett growled. “You didn’t compliment me!”
“You look very vampiric, Scarlett,” I bowed.
“That’s not a compliment,” the redhead pouted and pulled her cape around herself dramatically.
Orange and purple lights covered the porch of the Delta Tau Chi Sorority house. Fake spiderwebs stretched between the columns and along the windows. Carved pumpkins lined the steps. Someone had hung a skeleton from one of the second-floor windows, while a ghost swung from a tree.
Music could be heard through the walls and there were people everywhere. Costumed college students moved across the lawn and crowded the porch. A couple of guys were standing near the steps holding red cups. One guy in a toga was flirting with a girl dressed like a sexy pirate.
Unsurprisingly, a girl near the door immediately recognized Scarlett.
Scarlett smiled, flashing the fake fangs and somehow making them seem natural. “Happy Halloween!”
The girl laughed and waved us inside.
I stepped into the packed sorority house with Scarlett and Tasha, the loud music hitting me before the door even closed. Decorations covered basically every available surface. There were fake cobwebs and plastic bats. Someone had strung up more orange and black lights everywhere. A plastic pumpkin was on every table or desk that had enough room for one. A skeleton wearing Greek letters sat in an armchair near the entrance with a red cup wedged between its plastic fingers.
With the sea of costumes, finding people we knew would be more difficult than I thought. Instead of wasting time looking, we grabbed a few drinks and started exploring the house. It wasn’t long before we found ourselves dancing and laughing. It was nice seeing Tasha able to relax and enjoy herself. She had a huge grin on her face as I spun her.
Josh Greene was the first person I recognized from high school. I briefly thought he wasn’t wearing a costume. Then I noticed the name tag. “My name is God.” Very clever, and something I hadn’t expected from the shy guy. It all made sense when I saw Ashley’s costume.
She was the Devil. God and the Devil. Damn, Josh was one lucky bastard. I was trying not to think with my downstairs brain, but I couldn’t help but remember the one time I’d had sex with Ashley. Right before the Senior lock-in at Kayla’s place. Josh was in for an amazing night. Wow, the blonde’s cleavage was amazing.
I reprimanded myself for my thoughts and turned my attention to the rest of the group. Josh’s roommate, Derek, was dressed as a mad scientist. The equally shy biology major was nervously dancing with Josh’s gorgeous sister. Emily’s costume was a sexy pirate, complete with boots and a hat.
Lexi, dressed as an angel, noticed us. The redhead waved us over.
“Angel, devil, and God,” Scarlett observed with a giggle. “Clever. Let’s join them!”
Marcia was the next to appear, causing me to release a small laugh. She looked cute in a simple cat costume that looked like she spent five minutes putting together. At least she took the time to draw a nose and whiskers. Despite our sexual encounter, I saw my friend when the quiet girl smiled at me.
Beside Marcia was her friend and fellow honor society member, Lina. At first I didn’t understand the costume, the beads. Then I realized Lina was going as a fortune teller. The crystal ball was what gave it away. Clever. More clever than the guy dressed as a hot dog, or the one who actually came to a sorority party as a toilet.
We made it halfway to the group when my heart stopped.
Kayla.
Well.
Fuck.
She wore a pale blue dress that shimmered under the lights. The skirt moved around her legs when she turned, and translucent wings rose from her back. Small flowers were woven into her raven hair, and glitter sparkled around her perfect green eyes. She was holding a wand. A fucking wand.
A fairy. It was fitting. She was a goddess out of a fairytale. I couldn’t believe such a gorgeous creature had ever allowed me to touch her.
Scarlett made a noise beside me.
I jumped and looked at her. “Uh, what?”
“Hm, interesting,” Scarlett smirked.
Tasha looked at Kayla. Then at me. “Oh.”
I frowned. “What?”
“Your face,” Tasha answered. “Oh wow, you’re so adorable right now.”
“On that note...” I trailed off, closing the remaining distance to the group.
Kayla finally spotted me, her smile widening as we locked eyes. That didn’t help. Ashley reached me first, hugging me tightly before taking a step back to evaluate my costume. She shook her head in disapproval before letting out a sigh. Then she greeted Scarlett and Tasha.
I looked at Marcia. “Cat?”
“Nothing gets by you,” Scarlett grunted teasingly.
Marcia made a cute clawing motion with her hand. “Meow!”
I tipped my hat. “Lookin’ good there, little lady.”
“Get a room, you two,” Kayla giggled.
I coughed.
Marcia turned bright red. “I, um, uh...”
“Oh, no way,” Lexi appeared and threw an arm around Marcia’s shoulder. “The one Slut-sister Dan could never bag. She’s gonna remain a masturbatory fantasy.”
“Quite the fantasy,” I smiled lightly.
“It really is,” Ashley agreed. “And reality? Marcia’s great with her tongue.”
“Ashley!” Marcia hissed, looking mortified. “And, um, you forgot Nicole.”
“I like this group,” Scarlett smiled, exchanging a look with Kayla.
A look of mutual respect, maybe?
Kayla turned to face me, her eyes darting from my head to feet and back up to my face. “Cowboy?”
I tip my hat again. “Yes, ma’am.”
The cheerleader in the fairy costume grinned and reached up.
I moved back. “What are you doing?”
“Give me your hat.”
“What? No!” I laughed lightly.
“Why?” Kayla pouted while our friends watched.
“Because it’s my costume,” I reasoned.
“I want to wear it,” Kayla shrugged, standing on her toes to snatch the hat off my head.
She put it on. The hat was way too big for her, the brim dropping low enough that she had to tilt her head back to see me. It was funny and adorable. Was she flirting me? No, no way. She was just having fun with someone she considered a friend. Kayla had such a great personality. Shit. Don’t pop a boner, don’t pop a boner.
Lexi laughed and took her phone out. “Pose for us.”
Kayla put one hand on her hip, the other still holding the wand. “Howdy!”
Everyone laughed as Lexi took the picture.
“You’re a much prettier cowboy than I am,” I smiled.
“Uh, cowgirl,” Tasha pointed out.
“Right, cowgirl,” I agreed as Kayla beamed at me.
Removing the hat, Kayla held it out to me.
“Thank you,” I took it back and put it on.
“It did look better on me,” Kayla stuck out her tongue.
We spent a bit of time talking. Emily showed us the plastic sword and had a pretend fight with vampire-Scarlett. Derek explained the green liquid in the test tube clipped to his lab coat was actually a sports drink. Ashley drank some of it, making for a great picture. Lexi complained her halo kept sliding.
I kept an eye on Scarlett, concerned for how she was doing. What she told Tasha and me was still in my head. I remembered her crying: The Crocs, Velour Room, the things she’d done because she thought she didn’t have another choice. I remembered the relief on her face when she told us it was over; she was free.
Scarlett caught me watching her, her expression changing immediately. As we mingled, the redhead pulled me away from the group.
She wrapped her arms around my neck and looked at me sternly. “Don’t.”
“What?” I frowned.
“That.”
“I didn’t do anything,” I protested.
“You’re checking on me,” Scarlett accused.
She stared.
I sighed. “Okay, maybe just a little bit.”
“Dan.”
“What?” I asked innocently.
“I’m okay,” she insisted.
“I know,” I replied.
Scarlett arched an eyebrow. “Do you?”
I looked at her, grateful for the music that let us have this conversation without anyone overhearing. “I don’t know. What you went through...”
“Stop,” Scarlett stated firmly. “It happened, it sucked. If I need to talk, I know you’re here. Let’s have fun and be glad it’s over.”
“Scarlett...”
“Yes?” she asked.
“I’m sorry,” I said quietly. “For, you know, how we met. It was just sex. You deserved better.”
“Hey, I was a willing participant,” Scarlett reasoned. “You didn’t do anything wrong.”
“I just...”
She placed two fingers to my lips. “Stop worrying so much. You are a good guy.”
“What’s going on over there?” Emily called out.
“Looks like they’re getting comfortable!” Lexi laughed.
“Vampire and cowboy hooking up? Fun!” Ashley agreed.
Scarlett and I both flipped them off at the same time. Then Scarlett kissed my cheek before grabbing Tasha and dragging her off to dance. Josh was dancing with Ashley, while Emily continued to work on bringing Derek out of his shell. Marcia and Lina were sipping on drinks and chatting. Lexi ran off with one of the sorority girls to complete some pledge task.
Then somebody hip-checked me. “Hey.”
Kayla. She still had the wand.
“You planning on carrying that all night?” I asked with a smile.
“Yes,” she confirmed.
“Why?”
“Because I’m a fairy,” Kayla tapped me on the nose with the wand. “Would you like to dance with a fairy?”
“As long as the fairy is you,” I replied.
Her smile grew as she held out her hand. “Let’s go, cowboy.”
I took her hand.
Kayla pulled me into the crowd. I wasn’t good, but I wasn’t terrible either. What mattered is that I was with Kayla, and that she seemed to be enjoying herself. I did my best not to think about what happened to Kayla, about my unrequited love, or about Drew Kensington. Instead I allowed myself to simply enjoy her company.
By the time we left the dance floor, I was warm enough to regret the vest. Kayla grabbed two bottles of water from a cooler and handed me one. I leaned against the wall and took several gulps. Kayla stood near me, and the sight of her drinking the water entranced me for some strange reason.
“This is fun,” Kayla smiled.
“It is,” I agreed with a nod. “How’s cheerleading going?”
“Great!” she replied enthusiastically. “We’re preparing for nationals. It’s exhausting, but I love it.”
“That’s good,” I said, taking another sip.
“What about you?” Kayla asked me. “Big football star.”
“I don’t know about that,” I laughed lightly. “But things are going well. I’m a freshman getting field time. That just doesn’t happen.”
“I can relate,” she said. “It can cause friction. People think we haven’t earned our spot.”
“Yeah, I’m still not sure how Kensington feels about me,” I admitted.
“Football heroes aren’t known for their willingness to share glory,” Kayla giggled. “But our seven wins, two losses record speaks for itself.”
“That it does,” I agreed.
“You ready to go up against Arizona State tomorrow?” she asked.
“Yeah, I’m glad it’s a home game,” I replied. “If it was an away game, we’d have needed to miss this party.”
“That’s true,” Kayla nodded. “I’m glad I can be here for Lexi and Ashley.”
“They’ll be accepted,” I said confidently. “They’re both great.”
