“I love you,” she whispered.
I kissed her tenderly. “I love you too.”
She rocked her hips gently, taking some of her weight on her legs to give herself the needed flexibility. She didn’t move fast, and that was fine. The slow grind was perfect. I wanted it to last. I wanted the desire I had for her to burn steady for as long as I could stand it.
“I bought condoms,” I said. “I don’t want to stop right now, but maybe…”
Kylie laughed, clear and happy. “We don’t need those, silly.”
“We don’t?”
“No. I’m all tied down there. Baby-proof.”
“You are? Since when?”
“Did I not mention that?”
“No.”
“Oh. Oops. I wondered why you pulled out last time.”
I shook my head, then nuzzled and kissed her breasts to relieve some exasperation. “Here I was thinking we needed to be safer…”
“Yeah, no, I was on top of that. I mean, I know it was silly worrying about babies. I never really expected… you know, something like this. But just in case…”
I traced my fingers up her back. She maintained a steady rhythm, back and forth. Just enough to keep me on edge. “You’d never make it as a mom, huh?”
“Hell no I wouldn’t. It’s bad enough dealing with regular people. Can you imagine a little tiny person who’s, like, always there? Nevermind the bit where they come out of my vagina. Ick.”
I laughed and kissed Kylie again. “You’re so… you, sometimes.”
“Should I take that as a compliment?”
“Yeah. Yeah you should.”
Kylie shifted again to get her knees into a better position, but didn’t increase the speed or power of her slow, constant grind on my lap. I held her while alternating between staring into her eyes, and looking over her shoulder at the magnificent view out the window. It should have been just a tad scary to be fucking my sister while in theory we could be observed, but the height of her loft meant that it wasn’t really much of a worry.
“Are you gonna stay over again?” she asked, disrupting my idle train of thought.
“I thought I might.” I smiled as she kissed my cheek. “But you know I can’t stay here all the time.”
Kylie sighed. “I know. I hate thinking about it like that right now, but you’re right. I couldn’t handle having someone else here all the time. Even you.”
“We’ll work something out, yeah? Maybe on the weekends or something?”
“Yeah. Something like that.”
She still didn’t look quite convinced, so I did the only logical thing I could think of to reassure and cheer up my big sister; I picked her up and carried her off to bed, my cock still nestled snugly in her pussy the whole way.
I let my desire and need take over. I fucked Kylie hard on her bed while she grabbed and me and mewled happily.
I came inside her, free from the responsibility of being more cautious. She gasped at feeling cum spurt into her pussy, then grinned wickedly and rolled on top of me to keep riding.
My cock softened and got sensitive after my orgasm, but Kylie brought it back to life and wouldn’t let me have a break until I got off again. She’d reached a couple orgasms of her own by then, so she was content to let me rest after my second time.
