My dad recently remarried and with that came a nerdy little stepsister, named Leana.

Leana and I are very close in age. We get along well for the most part but recently she has been teasing me nonstop.

It all started when I told her that I thought her glasses made her look hot. Now she thinks I want to fuck her and she likes to tease me about it. I mean, she’s not wrong though.

Last week I passed by the living room and found her laying on the couch, video-chatting with a friend. I couldn’t help but pause and admire the view. I noticed that her skirt had ridden up and her ass was partly exposed. As I leaned in closer to look at her exposed ass cheeks her friend saw me come into view.

“Is that your new stepbrother checking out your ass?” her friend asked in shock.

Leana swung around quickly and caught me looking, “What the fuck are you doing?”

“I was just looking…”

“At my ass?” she said, cutting me off.

“For my phone.” I finished.

“Figures,” she scoffed, “You wouldn’t know what to do with it anyway.”

I couldn’t help but notice that Leana’s nipple had become exposed when she turned around quickly. I didn’t respond. I just stared at her nipple until she said, “What are staring at? Take a picture, it’ll last longer.”

“I would if I had my phone,” I mumbled under my breath.

“Whatever,” she huffed and turned her attention back to her friend on the phone.

I ducked down behind the couch pretending to look for my phone and hide from her friend's view.

Her friend said something funny causing Leana to laugh so hard that she had to reposition herself in order to catch her breath. Leana stuck her ass in the air giving me a perfect view of her full ass and panty-covered pussy.

I took a long look before remembering what Leana had told me. I fished my phone out of my pocket and snapped several pictures without ever taking my eyes off her.

Once Leana laid back down I no longer had a view up her skirt without exposing myself to her friend.

I started to slink away when I heard her friend say, “Your stepbrother is kinda hot. I might just let him fuck me.”

“Oh, my God! You would, slut!”

“Does he have a big cock?” her friend asked.

“How would I know?”

“I bet he does. If so, you’d probably fuck him first. I know you can’t resist a big cock.”

“Shut up, slut! I hate how well you know me,” she laughed.

Our teasing continued after this and the sexual tension seemed to thicken with each interaction.

I noticed that Leana seemed to be trying to sneak peeks at my bulge. I wondered if she really did have a thing for big cocks and what she would think of mine. I tried to hint to her that I had a big cock but she would always dismiss it as false boasting.

One day the two of us were home alone. We were just hanging out, having a good time when Leana suddenly announced that she was going to go take a shower.

“Hopefully you didn’t leave your phone in the bathroom and have to come looking for it,” she said with a mischievous smile and sauntered out of the room.

Was she teasing me? Did she think I didn’t have the balls to peek? Maybe she wanted me to look. My cock grew in my pants as I thought about the possibilities.

I was deep in thought when I heard the shower start. I immediately lifted up off the couch and made my way toward the bathroom. I was like a moth being drawn to a flame, but I didn’t care if I got burnt.

As soon as I rounded the corner I noticed that Leana had left the bathroom door open slightly. She really was willing to take our little game to the next level.

I peeked into the bathroom and saw Leana wearing nothing but a towel and her sexy glasses. My cock hardened further.

She was standing in the bathroom looking at herself in the mirror.

‘Was she really going to let me watch her take a shower? Did she know I was here? Did she care?’

Leana slowly started dropping the top of her towel down to her waist. My cock strained against my jeans and begged to be set free. I slowly and quietly opened the front of my jeans and pulled out my throbbing member.

I stroked my hard cock while Leana fondled her tits and pinched her nipples. My cock was dripping with precum and I considered walking into the bathroom and making my presence known.

Before I could do that though, Leana turned her gaze to me and smiled.

“I knew you wouldn’t be able to resist the chance to see your stepsister naked.”

I continued to grip my cock which was just out of her view.

“I hope you enjoyed your free show. But now you owe me one. Next time my friend comes over, you’re going to give her a show. Understood?”

I nodded my head and stared at her tits.

Leana took a step closer and reached for the door. She was just about to close it when my hard cock came into her view.

Leana reactively placed her hand over her mouth as she gasped in shock knocking off her glasses in the process. It just so happened that she used the hand that was holding up her towel.

“Oh my God, it’s huge!” she said in surprise.

I don’t think she even realized that she’d lost her towel. I looked at my beautiful stepsister standing naked in front of me. I saw for the first time that Leana kept her pussy shaved bald.

My cock twitched as she stared at it. Leana squinted her eyes at it and took a step closer, leaving her towel and glasses behind.

When she was standing right in front of me she dropped to her knees and looked intently at my cock. She never said a word, it was like she was in some kind of trance.

I didn’t say anything, as I didn’t want to ruin the moment. After a moment of staring, she grabbed my cock by the shaft and gave it a couple of strokes.

I watched her as she opened her mouth and leaned her head forward. I let out a slight moan causing Leana to pause and look up at me.

As soon as we made eye contact, Leana’s facial expression changed. She seemed to snap out of her trance, “My friend will really enjoy seeing this. I need to put on my glasses so I can describe it to her in better detail.”

Leana let go of my cock and stood. She gave me a nervous smile and turned around. She stepped back into the bathroom and I followed closely behind her. She said she wanted a better look and who was I to say no?

I was lost in my own thoughts again and didn’t realize that Leana had stopped and bent over to retrieve her glasses. I continued walking into the bathroom and accidentally slammed my crotch right into her ass.

Leana started to fall forward so I grabbed her by the hips and tried to hold her upright as we both stumbled to the counter.

“What are you doing?!” she yelled.

“I’m sorry,” I said, apologizing for bumping into her.

Once we had finally steadied ourselves, I realized that my cock was pressed directly against my stepsister’s pussy.

“You better be sorry, trying to fuck me without my permission.”

“No, that’s not it,” I tried to explain.

Leana looked back at me and pushed against my cock. I felt the head of my cock penetrate her opening, “It’s going inside me,” she moaned, “I can’t believe you’re fucking me right now.

“I know you've always wanted to fuck me, but not like this,” she moaned.

She didn't push back against my cock any further, but she didn't pull away either. We sat motionless for a second until I couldn't take it any longer. I slowly started to push my cock in further when she said, “Stop!”

I did and she pulled away from me, releasing our physical bond.

Leana grabbed my hand and said, “Come with me.”

I followed her into her bedroom where she stripped off my clothes and pushed me backwards onto her bed.

I lay there as she crawled onto the bed and straddled my crotch. My cock was pressed against my stomach and her pussy lips wrapped around my shaft.

Leana slowly slid her hips back and forth, rubbing her pussy across my hard cock. She moaned as she moved and I felt her pussy juices lubricate my flesh.

Leana removed her glasses and looked me in the eyes, “So you want to fuck your sluty stepsister with your big cock, don't you?”

“No,” I said.

“What?” Leana said surprised.

“No, don't take off your glasses. I want to fuck you with them on.”

“Oh,” Leana said with a smile and placed her glasses back on her face, “Better?”

“Much better.”

She then reached between her legs, lifted my cock, and slowly lowered down onto it.

“It's so big. Why didn't you tell me you had a big cock sooner?”

“I did, you never believed me.”

“I believe you now, so shut up and fuck me.

Leana was doing all the fucking as she rode my cock. I just lay there and watched her cute facial expressions behind her sexy glasses.

Leana finally got tired and rolled off of me. She spread her legs wide open and said, “Fuck me hard with that big cock and make me cum!”

I plunged my dick deep inside her and didn't let up until she was orgasming on my cock.

Her body tensed up and she moaned, “Yes, yes, yes...” over and over again.

“Your cock is so good! I want you to fuck me and then cum all over me.”

I grabbed her hips and pulled her ass up on my thighs. I then thrust my cock in and out of her with most of the pressure of my cock against her G-spot.

Within a few minutes, she was moaning loudly, “You're going to make me cum again!”

“I'm going to cum too,” I moaned.

I felt her pussy squeeze my cock as she came and after a few thrusts like that, I had to pull my cock out of her.

My cock erupted with thick shots of cum all over her stomach and chest. Some of my cum even landed on her mouth and glasses.

“Mmm,” she said as she licked her lips, “That was amazing.”

She gave me a great big smile and played with the cum on her belly.

“I'm going to go take a shower now, seeing as you left the water running. Hopefully, there's still some hot water left,” I said as I rose from the bed.

Just then Leana’s phone rang. She lifted her hand to see her fingers covered in cum. She quickly stuck her fingers in her mouth and sucked them clean before answering the phone.

“You’ll never believe what I just found out,” she said to her friend.

“What?”

“I'm not telling, you'll just have to come over if you want to know.”

“I hate you, you're such a tease,” her friend whined, “At least give me a hint.”

“Fine, here’s your hint,” Leana said and then panned the phone camera down her cum-covered nude body.

“You... Fucking... Slut! You found out he has a big cock and then you fucked him, didn't you?”

“Maybe,” Leana said coyly.

“I'll be there this weekend, and I'm spending the night. Don't wear him out before I get there!”

Leana looked up at me, smiled, waved, and said, “Okay, I'll see you this weekend.”

It turns out that having a nerdy little stepsister isn't so bad after all.
