Could this be a step too far?

Alice dragged me into the shelter and we layed in the hammock, she smiled at me as her fingers caressed the shaft of my cock.

“I know I said I was going to stop worrying about the things we’re doing so much, but what you said earlier, it’s making me kinda antsy,” I confessed.

She paused for a second and looked up at me. “It’s dirty talk. Don’t read too much into it,” she reassured me, leaning up and kissing me on the lips, while her hand went back to caressing me.

Somehow, Alice kept her lips against mine while her fingers still stroked my dick, as she twisted her body around and straddled me.

She placed both hands on my shoulders and pushed back, allowing me to steady her as the hammock swayed. She lowered herself until my dick was sandwiched between my stomach and her pussy.

The radiating heat and moisture from Alice’s crotch caused my dick to throb. Alice let out a long shuddering moan. “Fuck, I hope you don’t mind doing it like this again. Feeling your cock twitching and pulsating against my pussy… Fuck, it makes my knees weak. Oh don’t look at me like that, I told you, it’s just dirty talk….” She trailed off and I could barely hear what sounded like “Mostly.”

Maintaining eye contact Alice slowly ground her pussy from base to tip and back again before leaning down and kissing me. Her mouth opened and our tongues met, we moaned together before Alice pulled back once more.

She began grinding against me, her chest bouncing in front of me, the sensation and view spurred my dick to react, twitching as she moved. She stopped and leaned over me, her pussy hugging the tip of my cock.

She smiled and began rotating her hips, keeping the tip of my dick wedged right at her entrance. She let out a throaty moan. “Thinking about your dick going inside me turns me on so much. I’d have my first time right here on the island.”

I felt like I should discourage her from saying that kind of thing, but I couldn’t help find the fantasy hot, I knew that Alice was just saying it like she said it was just dirty talk.

My breathing became heavier. “Yeah? You want to have sex with your brother? Do you want to be your brother's slut, or are you imagining us being together?” I asked, teasing her.

She smiled and kissed me, her gyrating picking up speed a little. “Obviously I’d want you to be mine as much as I’m yours,” Alice answered.

“Mmmh, we couldn’t tell anyone, you know? It would have to be a secret from everyone. Maybe I’d have to sneak into your room at night,” I said, letting my hands wander a little and allowing my right hand to settle on her tit, grazing my thumb over her nipple.

She moaned and arched her back. “Yeah? You’d come and defile me with only a wall between us and our parents? You’d definitely need to get used to getting woken up inside my mouth or pussy,” Alice teased back.

I pulled her down onto me, guiding her face close to mine and kissing her. I began thrusting against her, one hand on her hip and the other still on her chest.

We moaned against each other again and I smiled. “If we were a couple,” I said, kissing her again. “I’d take you out of town, and I’d make sure everyone knew you were my girlfriend, every guy would be envious.”

Alice smiled at me. “I would love that, making out with you and being romantic in general would be amazing, but think about what we could do in plain view of people we know. People already say we’re really close and physically affectionate, I wonder what we could get away with doing when others are around. We could probably go an entire car ride with you inside of me with our friends sitting all around us, completely oblivious,” she cooed.

“Fuck… I don’t think we could actually do that, people would notice too much,” I objected.

She kissed me again. “You think? It wouldn’t be the first time I sat in your lap in the car. I’m sure we could do it, I’d just wear a short flowy skirt without any underwear, and you would wear some loose shorts or sweats. If we were the first ones to the car you’d just have to pull your dick out quickly and I’d sit right in your lap. Most of your friends tease you when I have to sit on your lap, so we’d be going down the streets with the most speed bumps, so they’d essentially be making us fuck without even realising it,” Alice breathed.

“Hey, Alice. I think I’m getting close,” I warned.

Without warning she rolled off of me and onto the floor, kneeling next to me. Her lips quickly sealed around my dick and pleasure coursed through my body. The sensation of her mouth and the sound of her fingers playing with her soaked pussy sent me over the edge.

As I came Alice moaned, I couldn’t tell if it was because she’d cum at the same time or if it was because she enjoyed the taste of my cum in her mouth.

Once I was completely spent and after she’d ensured to suck every drop out of me, she smiled at me and climbed back on top of me, snuggling into me. She let out a content sigh and closed her eyes. “Night Robin, love you,” She murmured.

“I… Love you too Alice,” I replied, stroking her hair as I slipped into a restful slumber.
