The unnatural progression of things

I drank it all down greedily until she finally released me with a shuddering breath, and I fell back on the floor, coughing a little.

“Sorry,” Charley muttered, blushing hard. “I didn’t mean to lock you in there.”

“I don’t mind. You taste amazing.”

She looked down at me doubtfully. “Really?”

“If you don’t believe me, you could always try it yourself.” Not waiting for her to answer, I reached down between her thighs and slid a finger inside of her soaking wet pussy again, coating it with her juices.

As I stood up and brought my hand back up towards her face, Charley regarded my glistening index finger with a mix of uncertainty and curiosity.

Her eyes flicked back to meet mine. “You’re a perv, you know that?” she said softly.

I was just about to dejectedly wipe my finger off, when she opened her mouth slightly and nodded. Heart pounding, I slowly lowered it into her waiting mouth, her lips closing around it gently.

Somehow, in that moment it felt like the hottest and most intimate thing we’d ever done. She gazed up at me the whole time, looking deep into my eyes as she sucked on my finger and swirling her tongue around it. This was supposed to be for her, not for me, but within seconds I could feel myself growing almost painfully hard.

It was apparently doing something for her too, because she suddenly moaned. Feeling the vibrations on the tip of my finger, I withdrew it from her mouth and stared back down at her in anticipation.

“Not bad,” Charley whispered. “But I need you inside of me now.”

I nodded. “Lie on your stomach.”

“Okay,” she replied, a glint in her eye.

After doing as I asked, she watched me over her shoulder as I slowly climbed on top of her, leaning on my arms and lining up my rock-hard cock with her sloppy pussy. Charley rocked her hips from side to side as I rubbed the head up and down her slit and gasped loudly as I parted her lips and began to sink inside.

As I bottomed out, she let out a deep groan of satisfaction. “Holy … you’re so deep like this.”

“That’s the idea,” I muttered.

Holding myself in position for a second, I savored the feeling of her inner walls tightening and twitching around my erection, along with the sensation of her soft, pillowy ass against my hips.

“Luke,” Charley whimpered, and as she looked over her shoulder again, I leaned down to kiss her gently. As I probed my tongue into her mouth, I could feel her pussy throb and I began to slide in and out of her.

Pulling back from the kiss, I rested on both my hands and got into the rhythm. I ploughed her from behind slowly and sensually, relishing in the feeling of her body vibrating each time my hips collided with her backside, feeling the two of us become drenched in sweat despite how steady and deliberate the sex was.

“You feel … so fucking amazing,” I panted, my eyes almost rolling back in my head as I experienced her tight, slick pussy lips gripping my shaft like it never wanted to let me go.

Charley just groaned in response; her face buried in her sheets. I really was getting deep inside her in this position – on each thrust, I could feel myself reaching her cervix, and each time my cock bumped up against it she mewled loudly. It truly felt like I couldn’t get any close to her than I was in that moment, and the feeling really was blissful.

I was in no rush to finish, but the sheer intensity was taking its toll on my endurance. My arms shaking, I let myself collapse on top of her, our sweaty bodies now firmly pressed together as I continued to grind my dick within her scalding pussy.

“Charley … I’m going to cum,” I whispered in her ear, holding her tightly from behind.

She took a second to formulate the words, but eventually I heard them, muffled but unmistakable. “Me too.”

After a few more deep thrusts into quivering, soaking snatch, I felt her stiffen up and cry out, her walls clamping down and rippling on my swollen wood as she flooded the area with a river of her juices. Within seconds, I felt myself topple over the edge with her, exploding with a loud groan and flooding her spasming pussy with my hot cum.

Completely empty of energy, I leaned over to rest my head on the sheets beside her. We both lay there exhausted for at least a minute or two, catching our breath and coming down from the post-sex haze.

Finally, I heard her quiet voice, still muffled by the sheets. “Luke?”

I gently climbed off of her and rolled over beside her on the bed. “Yeah?”

She shakily looked up to face me, still red and sweaty, her hair matted down and unruly. And still the most stunningly beautiful girl in the world. She shuffled a bit closer to me and leaned in to kiss me slowly. It was sweet and gentle, just the two of us basking in affection and each other’s company.

After the week of overthinking, it had gone about as perfect as it probably could have – lying there in the bed with her, I felt happier and more content than I could have ever imagined possible. But there were still unanswered questions – and while they absolutely didn’t spoil how this all felt, they still nagged at me in the back of my mind.

After a while, I could sense it was getting late. I gently untangled myself and sighed. “I should probably head off soon.”

“You know…” Charley hesitated, and for a second I could have sworn she seemed a little nervous. “You can stay over if you want.”

My heart skipped a beat. “Are you sure? Mum and Dad might-”

“I have a sofa bed, you know. It’s not like they’re gonna jump to the conclusion we’re sleeping in the same bed.”

I grinned. “Which … is what we’ll be doing?”

She shot me a dirty look. “If that doesn’t sound appealing, the couch is right out there.”

“I like where I’m at,” I laughed, reaching over to pull Charley into a cuddle. She harumphed quietly, but it didn’t take her long to get over herself and lean into it with me.

A while later, when Charley had fallen asleep, I lay there still thinking about everything. Everything was still unclear. I didn’t want to be the needy, ‘What are we?” type of guy – but then again, I felt like our relationship was unique to the point that those kinds of questions might be necessary.

It was only just as I was about to drift off myself that I remembered my mum’s offer to meet up. I sleepily grabbed my phone and sent over an affirmative message.

Despite everything, my relationship with her really wasn’t that complicated. I couldn’t help but hope that being around her might give me some clarity on the far more indefinite relationship I had with my stepsister.
