My stepsister Ari laid on the floor, her face covered in my cum, gasping in part from the enthusiastic blowjob she'd just given me and in part from her own earth-shaking orgasm after I'd finally given her permission to cum. It had been less than 24 hours since I'd picked her up from the airport and in that time I'd found out that she had a thing for big, muscular guys (which I would argue I'm not) who take control in the bedroom. I'd also found out that there was something in me that wanted to take that control.
Ari smiled and let out a satisfied moan as she reached up to touch the cum on her face. "It feels like I'm drenched! Could you get me my phone? I want to see the mess you made."
"OH! Yeah, sorry, let me get you a towel too." I slipped my sweatpants back on and went to the bathroom to find a towel and our phones where I'd left them while hanging up our wet clothes from the night before. I felt Ari's clothes and noted that they were still damp. My shirt and jeans hadn't dried either, but I figured that being shirtless for the morning wouldn't hurt. I wondered if Ari would fit any of my clothes or if she was too petite. I was only 5'11" but I'd put on enough muscle to go up a size and she was only 5'1" and barely half my weight. Something to figure out later.
As soon as Ari had her phone back she opened the camera app and giggled "OH GOD! How did you cum that much bro?" She grinned and took a few selfies, making various poses, some sexy, some silly as she licked some of the cum off her lips. I watched my sexy little stepsister taking teasing photos for a few minutes before I felt my cock stiffening again and figured that I should at least go fix us some food before I got other ideas.
As I rummaged through the fridge to try and figure out breakfast I heard my phone buzz from the counter and checked it to find that Ari had sent me at least a dozen photos. Just then another file came in and it showed a short video of her gathering cum off her face with her fingers and rubbing her cum-covered fingers across her clit and pussy lips. "Fuck..." I breathed as I immediately thought of pumping all of her holes full of my cum. I knew that if I went in there right now that my stepsister would be eager for my cock. That all I'd need to do would be to demand it and my stepsister would be my personal sex toy. I tried to convince myself that I didn't want that. That fucking my stepsister was wrong. That treating her like a cheap slut was wrong. I wasn't doing a great job of convincing myself.
I got some bacon and eggs out of the fridge as Ari poked her head around the corner into the kitchen, a few strands of cum still decorated her smiling face. "Hey, fixing breakfast?" I nodded and looked away, not wanting to feel the guilt that came from getting turned on at the sight of her. "Make sure there's plenty of protein, gotta refuel y'know. I'm gonna go get in a nice hot shower and wash some of this sweat off." I took a deep breath and focused on cooking, doing my best to keep thoughts off my stepsister.
A short while later Ari came back into the kitchen wrapped in a towel and I breathed a sigh of relief that she was at least wearing something again. I set a couple plates of bacon, eggs, and toast down on the table and poured us each a mug of coffee. Ari grinned and immediately took a sip of her coffee. "You do know how to make a woman happy don't you bro?" I blushed at the compliment and sat down in front of my plate.
I had just started to dig into my eggs when I looked up and saw that Ari's towel had slipped and she was now sitting at the table, sipping her coffee, naked from the waist up. I sighed and put down my fork full of eggs. "So... are we gonna talk about all of this?" I said, not knowing how to start.
"Talk about what?" she grinned as she took a bite of bacon.
"C'mon Ari. What's all this about? I refuse to believe that me putting on a bit of muscle suddenly makes me irresistible to women, especially my own sister."
"STEP sister."
"You and I both know that hardly matters. We've been siblings for practically our entire lives. This is wrong."
Ari glared at me. "Jesus fucking christ. You can't ever just enjoy yourself can you? It's always gotta be 'Wait let's talk about this. Let's plan out every minute of our whole goddamn lives.'"
I glared back at her. "People need to fucking plan Ari! If it weren't for me then we wouldn't have gotten the rental car or the firewood or even the groceries. I knew you'd show up at the last minute expecting everything to be taken care of for you and sure enough you did and THIS time it bit you in the ass and now you're stuck here without clothes."
Ari glanced away for a second and took a deep breath. "I'm not saying I don't appreciate you taking care of that stuff. I'm just saying that you can't ever just relax and have a good time."
"You're saying that like I'm some stuck up asshole who can't watch a movie without criticizing it, but what you're talking about is fucking your sibling."
"SO WHAT IF I AM!? It doesn't change the fact that you're so wrapped up in your own head that you're turning down a hot, willing partner. We're both adults, we're both attracted to each other. I could go on but I think you get the fucking point. We're you like this with your girlfriends? Is that why you're single?"
"That's enough Ari."
