Unprotected sex

"What started it?" I asked.

"You're a hunk!" she laughed. "But seriously, I don't think any one thing started my feelings for you, they just happened, like everyone else who falls in love with someone they meet. I remember one time, you brought home a girl, and you two were fucking in your room while mom and dad weren't home yet. I got so fucking jealous..."

"Wait, a few years ago? When you started acting out and getting in trouble?" I asked.

"Yeah," she said.

"You were jealous that I was with a girl?" I asked.

"Not that you were with a girl, but the fact that the girl wasn't me..." she said. "After that, I started having sex because I wanted to bring home a guy so you'd have to hear me having a good time... never happened." She replied.

"Wow," I muttered.

"Yeah..." she said. "Lately, I've thought about it even more, and I decided to test you... to see how you'd react to the concept of me..."

"So your phone‒" I said.

"Was just fine," she laughed. "I wanted to see how you'd react to seeing me naked, and that seemed like an easy way to do it... I took those pics literally minutes before coming to your door." She added.

"Look, Vicky, I meant what I said about incest... I don't really have a problem with two related people hooking up, as long as both are consenting adults," I said.

"So... how do you feel about you and me?" she asked.

I sighed, knowing I didn't have an answer for her, but I looked into her eyes and smiled at her, tenderly.

"Let's find out," I said.

"You mean, you're willing to give us a try?" she asked.

I simply nodded, but it was as if I'd given her the world, by her reaction. Her eyes lit up, she smiled at me, and our lips pressed together in a passionate embrace.

After our conversation, we went back down the living room to watch some TV, and to talk about our situation. There was talk about sex, more than anything else, something she obviously wanted pretty badly.

"I just think it would be really special," she said. "I don't really feel like we'd need to worry about it."

"Yeah, but if we fuck, I'd have to pull out or something," I said, "it just wouldn't be a good idea to start fucking without a plan, you know? Unless we got some condoms, then‒"

"Fuck that!" she scoffed, "I can't stand the way condoms feel... too fake, not personal enough." She said.

"What about the pill?" I asked.

"They make me sick..." she said, wrinkling her nose.

"Okay, then pulling out it is," I said.

"I guess," she replied with a disappointed tone. She started playing with my hair at the back of my neck, as we stared into each other's eyes.

"So, like, you wouldn't mind having sex with your younger step-sis?" she teased me.

"You make a strong case in favor of doing so," I laughed a bit.

"How about right now?" she smiled.

"What if the neighbors see us?" I said.

"What are they gonna do, call the cops?" she laughed.

"Yeah, probably. Or at least tell mom or dad.

"I doubt it. For one, they'd have to explain why they were peeping into the house in the first place, and that's a crime" she said.

She untied her bikini top and tossed it aside, once again giving me full view of her tits. But she didn't stop there, she slid her shorts off as well, and climbed on top of my lap, facing me in a straddling position. We started making out, and I found myself playing with her tits as she rubbed my hard dick over my shorts, with her pussy.

After a few minutes of this, she'd made a wet spot on my shorts, and finally opted to pull my dick out. At this point, I didn't stop her, I was too horny to care what was about to happen, and I disregarded any thoughts I had of not fucking her, fully.

She lowered herself onto me, my d*ck slid in her pussy with me and started riding me.

I couldn't believe how wet she was, nor how tightly her pu**y wrapped around my d*ck, it was as if the two were made to do this, as if we were always destined to fuck each other, that no other combination would be as satisfying to us, as we were to each other. I found myself already nearing a climax. I'd never been so turned on in my life, and it was hard to fight my body's reaction.

"I know... fuck, I'm so turned on right now!" she moaned. Her motions sped up, which didn't help me settle the reaction at all.

"Slow down, you're about to make me cum!" I whispered. She ignored me and started riding faster.

I could feel her pussy wall contract around my dick, which sent me over the edge. I couldn't pull out with her on top of me, and in a mix of panic and pleasure, I shot a huge load inside her while she moaned and convulsed from her own orgasm.
