My Stepsister Is Such a Coctease

My stepsister is such a cocktease. My mom married her dad about 2 years ago, while I was still in college. He was a dentist she had met at some medical conference. Needless to say they hit it off. He's alright though. I only met him once before the wedding when we went to a Kings game. His name was Tyler DeLait. Big family, old money. Wasn't arrogant about it though and I new it would help take care of my mom. Hell, maybe even some of it would come to me.

The wedding was a fucking party. Everyone was boozing we were honestly having a blast. I went to the punchbowl to refresh my drink just as these two girls kinda cut me off. I was about to say something when I noticed how good their asses looked in those dresses. One girl had red hair and a green dress the other girl was in a petite blue dress with a blonde bob. I decided to introduce myself.

I almost pissed myself when the blonde told me her name. Zoe DeLait. My moms new step daughter. I laughed it off and tried not to let off that I was just checking out her perky ass. It was so tight on her she couldn't not know that NO! She is gonna be your stepsister. You can't be thinking like that.

She gave me a hug introduced me to her friend and they made their way back to their seats giggling about something. God I hope she didn't feel my hard on.

Things were pretty normal after that though. We went to different schools and we didn't talk to each other too much. We'd watch watch others instagram stories but that was about it. My sister posted a lot. It seemed like she was always doing something crazy, winding up on boats with her hot friends. Most of them were sorority sisters I think. She would post a lot of picks of her and her friends, a couple of which I followed too. They gave off the type of vibe that they were given whatever they wanted. All they had to worry about was looking hot on their socials. Zoe had this yoga girl aesthetic she was going for.

For fall break I decided to stay with my mom and Tyler for once. I typically stayed with my dad. He's closer and lives where I grew up but I wanted to see my mom. And I hadn't really given the new side of the family a chance. I got to their house and Mom and Tyler showed me to the guest room. Probably the nicest bed I've ever slept on. My own private bathroom too. Tyler was showing me around when Zoe got home.

"Hey Princess" Tyler said.

"Hi Daddy!" Zoe said.

"How was the gym?"

"Great. Killer leg day."

No way, I thought to myself. This girl looks like she didn't have a drop of sweat on her. She looked

like she was ready to star in a fitness commercial. A two piece hot pink workout set with some white nikies.

"You remember Cody right?"

"Yeah of course. Your mom talks about you all the time" She said "Just let me take a quick shower and put myself together for dinner tonight. We're still going to Sinclairs right? Cody, you'll love it. It's my favorite."

I went back to my room and finished unpacking while I caught up with my Mom. About an hour later I got on the nicest shirt I had thought to bring and got freaky for the restaurant. Zoe came down wearing a black cocktail dress. Never in my life have I seen a dress for a woman more perfectly. It looked so soft and snug on her I almost got a hard on immediately. And her ass could barely fit in that thing yet somehow still bounced and swayed with every movement. She was hypnotic. She walked over to me and I had to you all my strength, both physically and mentally, not to stare at her perfect body.

"You look nice." She told me. I knew how to put myself together. I never really had a long term girlfriend but I've had a couple situationships in school. I knew I was decent looking and was ok at talking to girls. But something about her made me incredibly nervous. Why would you wear such a sexy dress to a family dinner. Spoiled sorority girl. Probably the most modest thing she owned. But that smile she had on made me think she knew what she was doing.

"Thanks. Y-you too"

She giggled. Did I really just do that. Did I really just fucking stutter in front of her. Pull yourself together man. She spun on her heel and started walking for the door. This time I didn't even try not to stare. Mom and Tyler were already in the BMW waiting for us and there was no one who could see me looking.

"Zoe dear, you sit up front with your father," my Mom said. "Cody and I need to catch up." I was able to calm down during the ride to the restaurant. I was kind of the topic of conversation in the car. What had I been up to. Did I like my classes. No, I don't have a girlfriend. I asked Zoe about the gym a bit.

"There's a really great gym just a couple minutes from home. You should totally come with me sometime."

I started to imagine all the other outfits she might have and how hot she would look in them. The hard on started to come back and just when we were pulling into the parking lot too. Fuck fuck fuck. I got out first and quickly turned to hide it.

"Someone's hungry" Tyler joked.

Sinclaires was an upscale seafood place. And Zoe was right. I did love it. She sat across from me. I tried not to steal too many glances at her cleavage during the meal. When ever I went down to my plate to dig in I was able to get fix mix. That usually lasted about 5 minutes before I had to get another look.

Conversation was mostly just small talk. Zoe went on and on about the trip to Italy she and her friends went on. I told her I had seen some of her stories. She had been posting a lot of pictures of her and her friends going out and clubbing. On one of her friends stories I saw Zoe throwing it back on some foreign dude while her friends started screaming in the background. I can't say I wasn't a little jealous.

We had a little wine with our dinner and soon it was time to go home. This time Zoe sat in the back with me. She didn't talk to me though. She spent the whole ride on her phone.

We got home and we all went back to our rooms for the night. I couldn't stop thinking about Zoe's ass in that dress. I pulled up her social account. I rubbed one out to her and a friend doing a TikTok dance that was popular about two months ago. I changed into my sweats and got comfy with a book, my head finally clear.

I was up reading at about 11 when I left my room for a glass of water. As I open the door I found Zoe in the midst of trying to sneak out dressed as a slutty army girl. In camp booty shorts and crop top. Two black lines under her eyes like a drill Sargent. She even had a whistle. She was scared shitless when she noticed me.

"Fuck I thought you were my dad"

"Why are you sneaking out?" I asked her. "You're 21. And your dad seems pretty chill."

"Typically he is but he can also be super stuck up. He doesn't like when I dress like this." I looked down at her outfit. Honestly it seemed to cover more than her gym outfit from earlier but I kept that to myself. "If he knew I was going to a party he'd want me to bring you. But guys can't really get in this party unless you bring a hot girl and I'm already taking this guy I've been talking to. I know you wouldn't care though."

For the third time today my dick betrayed me. Thank god I just jacked off or else I would be rock hard in front of her immediately. I couldn't last long.

"Yeah no worries. I'm pretty tired tonight anyway, I'm probably gonna crash. And don't worry, I won't tell your dad."

"Thanks I owe ya one." She looked down and smiled. She skipped out while I turned back into my room to jerk off again.

This is going to be an interesting week.
