It was early morning when I woke up. James and Max seemed to have gone down for breakfast.
The day before had been a wild time, and I couldn't stop thinking about everything that had happened. First, James and Max fucked Autumn, Erika and me in the morning. Then in the afternoon, I fucked my dad! Dad's cock was even bigger than Max's, and he absolutely dominated Autumn, Erika and me as he fucked us senseless.
I had gone out for drinks with Erika and Autumn last night, and my brothers were already asleep by the time I returned.
I got up and quickly showered before heading to the restaurant for breakfast. I was wearing a pink bathrobe and putting on some make-up when Autumn and Erika burst into my room.
"Happy Birthday!" they both shouted together. They were both wearing slutty little sundresses and high heels. They were both wearing matching pink lipstick and had their hair done.
I just stared at them in confusion as I tried to make sense of what they were saying. It took me a few seconds before I remembered that it was my birthday today.
"Oh, my God! I forgot that today was my birthday?" I said with a huge smile on my face. I hugged Autumn and Erika and sat down on the bed.
"We thought we would bring the party here!" Erika said with a naughty smile as she handed me my present.
I unwrapped both the presents and was surprised by what was inside. It was a sexy little mini-dress and a matching pair of sexy black high heels. "Oh, my God! You got me these!" I said as I held the items up and looked at them in awe.
"Happy birthday, baby!" Autumn said with a smile.
I stared at the dress in awe as I tried it on. It was really tight and showed off my toned body. I gave the two a smile and did a twirl. I leaned in and gave Autumn a quick kiss on the cheeks. I hugged Erika and kissed her on the cheek, but she pulled me in and kissed me on the lips. She licked her tongue over my lips before pulling away with a naughty smile. I was surprised by it, but I loved it!
"We've already fucked your father and brothers together. So what's a little kissing between friends?" She said with a naughty smile.
"It was hot, wasn't it? Being fucked by James and Max?" Autumn asked with a smile as she wrapped her arms around me.
"I never thought that fucking my family with my friends would be so hot!" I said as I felt her soft breasts against my back.
"And having your father fuck you so hard was hot, too, wasn't it?" Erika whispered in my ear.
"Mmm... so who do you want to fuck first on your birthday! Your dad or your brothers?" Autumn asked.
"I've got a better idea. We can fuck all of them and have a huge orgy! What do you say?" Erika said with a grin.
I stared at them in shock as I tried to figure out what they had just asked me. I couldn't believe it. They were right. The whole day had been a whirlwind of sex, and I loved every moment! I had lost count of how many times I had cum that day. I couldn't believe that I had just fucked my dad and my brothers the same day. And I definitely wanted more.

Soon, Autumn, Erika, and I headed downstairs for breakfast with my family. I was wearing the sexy black mini dress and high heels that they had gotten me for my birthday.
We found my family already eating breakfast in the restaurant. My parents and brothers were sitting there. I went up to the table and kissed my father on the cheeks. I then gave my brothers a kiss on the cheeks.
"Happy birthday, baby!" my dad said as he handed me a large cup of coffee. "I love what you are wearing." He whispered with a wicked smile.
I sat down next to Dad. Autumn and Erika sat down opposite me, beside James and Max. I looked over at Erika and winked at her. She smiled and winked back at me.
"So what are we planning to do today, honey?" my Mom asked as she put her hand on my arm. "We are up for whatever you suggest?"
"Well..." I said as I turned to face my Mom. "We girls were planning to go out shopping. I was wondering if you guys could join us?" I asked my family.
"Oh, that would be so fun!" my mother said with a smile. "I've never been to one of those before." She said as she smiled at me. "What do you think, Tommy?"
"Sure, babe. I think that would be fun."
"Sounds like a plan to me!" Autumn said as she looked around the table with a grin.

Soon Mom, Autumn, Erika and I walked around the Vegas strip together. We were all talking and laughing along the way. As we passed the cosplay store, I put my plan into motion.
"Hey, Mom, this seems like a cool store. Halloween is coming around in a few weeks, and you can pick out a few things to wear, and I'll look around for some things as well."
We started browsing the store and soon stood near the slutty costumes section. There were lots of sexy little outfits that could be used at a costume party.
"These are really skimpy..." my mother said as she stared at a slutty nurse's uniform.
"Mrs Stevens, you could wear those. I'm sure Mr Stevens would love seeing you in them!" Autumn said as she pointed out a slutty maid outfit.
"Oh my! I'm not sure about that!" my mother said with a smile.
"Come on, Mom!" I said as I pushed the items into her hands. "I want to see you wear them!"
My Mom reluctantly agreed and let us help her try the outfits on. I picked out a sexy little policewoman outfit and a slutty doctor outfit. My mother looked so hot in the outfits that I could barely wait to get her home. My Mom was blushing the entire time, but she was enjoying trying the outfits on.
"I saw this on the way in." Autumn said as she pulled out a sexy little French Maid outfit. "Try this on, Mrs Stevens!"
My Mom reluctantly agreed and quickly put on the French Maid's outfit.
I had never seen my mother in anything that slutty, and she looked so hot wearing it! The outfit showed off her cleavage and her long legs. My mother wore the thinnest pair of white stockings I had ever seen. She was also wearing a sexy garter belt. The translucent stockings made her look even hotter.
She spun around and looked at herself in the mirror. She was blushing as she saw herself in the outfit. "I don't think your father will be happy with me in this."
"I think it looks amazing, Mom! We are getting this!" I said as I grinned at my friends.
Soon we had picked out a few more slutty outfits for all of us to wear.
"Well, let's get these packed." my Mom said as she turned to the trial room.
"Actually, I thought we could wear these now and show the boys. There are a bunch of these cosplayers at the con anyway," I said with a naughty smile.
"Oh my... That would be so embarrassing!" my Mom said as she blushed.
"We'll also be wearing these, Mrs Stevens, just for the four of us!" Autumn said as she stared at my mother. "Please, Mrs. Stevens! Just try it out!"
"Yeah, Mom! Please!" I pleaded as I looked at her.
"Okay... Okay..." My Mom said with a nervous smile, "I'll try it out. But I'm sure your father won't like it."
We soon left the store, looking for my father and brothers. We found them hanging out near a stall. Their eyes popped out as they saw what we were wearing.
Erika was wearing a slutty schoolgirl costume. It was a tight little skirt that barely covered her ass cheeks. She wore a tiny white buttoned shirt and a pair of knee-high socks. Her breasts were totally exposed in the outfit, and I could see her nipples poking out in the shirt.
My mother was wearing a slutty maid's uniform. It showed off her long, toned legs. Her breasts were pushed up so that they were pushing against the material. Her cleavage was spilling out of the top, and she wore a garter belt and thinnest stockings.
I had gotten a sexy girl scout costume. The skirt was really short and showed off my bare ass cheeks. My breasts were spilling out of the top. I had put on the cutest pair of red high heels that I had found in the store.
Autumn had gone all in today as well. She wore a sexy princess costume with a gold bikini and flowing transparent leggings. A tiny thong barely covered her pussy, and her long legs were completely exposed through the transparent leggings.
We slowly strutted towards them in our costumes. I could tell they were already hard from what we were wearing. We slowly stopped right in front of them and smiled at them.
"Wow! Angela, you look hot!" Dad said as he stared at my Mom.
"Oh my god!" Max and James both said at the same time. They were both staring at Autumn and me in shock.
"What do you think, boys? You like?" I said with a smile as I slowly spun around, letting them take in the sight of me.
"Yeah... You all look so hot!" James said as he stared at us.
"I'm sorry, honey, but the girls convinced me to try these outfits. I know they are very slutty, but after all, we are in Vegas!" my mother said as she smiled at her husband.
My dad just grinned at his wife. "Well... I guess it's okay..." he said as he looked at his wife. "You do look hot in that."
"Mmmm... thank you, sweetie!" my mother said as she gave Dad a peck on the lips.
