“You’re amazing,” I told her. “I’m so lucky to have you as my big sister.”
“Damn straight,” Darcy said. Now there was the older sibling I knew and loved.
I took my sister in my arms and we held each other tight, the warmth of our naked bodies pulsing against each other. I caught the hint of my sister’s arousal and it called to me. I pushed her back on our parents’ bed and kissed my way up her legs. Her thighs were already sticky with her juices.
“Ethan,” Darcy put her hands on my head, but I pushed forward despite her protestations.
“You first,” I told her.
Darcy didn’t say anything, so I took it to mean she accepted my argument. I lapped at my sister’s slit and she moaned. She tasted slightly different somehow. Just as good, but a little stronger maybe? I noticed her lubrication wasn’t as I remembered either – it was clearer than I remembered and slightly thicker.
Darcy ran her hands through my hair and kept suckling at her sex. I tongued deep inside her cunt and felt her body tighten to my delight. Then I found her clit with my finger and my sister shook like she’d been shocked.
“Oh wow,” Darcy said. She sat up and this time pushed at my head more forcefully.
“Did I do something wrong?” I asked.
Darcy kissed me, tasting herself on my lips. “No, you’re perfect,” she said, “I just want to make you feel good, too.
Darcy pushed me back by the shoulders. She climbed on top of me. I waited for her to spin around so we could get each other off, orally. Instead, my sister kissed my lips again. I felt her shift her hips, so that my cock was pressed against her sex.
“Darcy,” I said.
“It’s OK,” Darcy said. “Just… just rubbing.”
She made her point by grinding down on my cock. We both groaned in pleasure. I arched my butt upwards to increase the contact. Darcy’s eyes rolled back as another small orgasm coursed through her.
My sister put her hands on either side of my arms and rolled her pussy back and forth over my cock. It felt amazing, the heat and lubrication of her sex dripped down my dick. I didn’t think I could cum just from pressing down. Now I wasn’t sure how I wouldn’t cum from it. But I didn’t want to get off. Not yet. I knew my sister had already orgasmed once, but I could feel she had more to give. I wanted to last as long as I could for her.
Darcy sat up for a moment and flipped my cock, so it was pointing upwards. Then she sat back down on it and draaaaaaggged her snatch against it. It didn’t feel as good for me, but it seemed to do wonders for my sister. Her breath caught in her throat. She smiled down at me, little flutters of illicit pleasure popping off like flashbulbs behind her eyes.
I rested my hands on Darcy’s ass and squeezed at her cheeks as she rolled back and forth. The third time she did it, I felt my dick pop up between her legs, and, for a moment, it kissed at her cunt. But Darcy lifted and guided my dick back into place.
It happened again. Darcy held me there longer. Teasing me. I could feel the wet heat of her opening start to crown around my cockhead. Then she bounced back up and it was gone.
The third time. The third time my cock ended up right at her entrance. Darcy tried to move but I held her hips in place.
“Ethan you said you wanted to wait,” Darcy said.
“You feel really good,” I said.
“Ethan you said you weren’t ready,” Darcy said.
“I know, I just…”
Darcy started to move back. For the first time in my life, I felt the warm tightness of a vagina wrap around my dick. My sister’s pussy. I gripped Darcy’s hips and held her there.
“Condom,” I croaked out.
“I don’t want to feel a rubber,” Darcy said, “I want to feel you,”
“Are you safe?”
“I trust you,” Darcy said.
That was the second time she’d said that, in answer to that question. It wasn’t the first time I wondered what she really meant by it.
“It means I trust you to do what’s right,” Darcy said, “When the time comes.”
She moved back. It felt like being slipped into an impossibly tight, incredibly slick, unimaginably warm place. It was indescribable. Imagine spending your whole life incomplete, only not knowing it. Then my sister slipped my cock into her cunt and I realized what my life had been missing.
“Whoa boy, go slow,” Darcy said. I hadn’t realized I’d started thrusting into my sister as hard as I could. “It’s been a while since I’ve done this, I’ve never had a cock as thick as my brother’s inside me, and I want you to last. OK?”
I nodded. I made myself put my arms behind my head and let my big sister set the pace. My dick inched inside of her, feeling better and better.
“Oh God that’s GOOD,” Darcy said. “See I told you. Something about brother and sister makes it so much better.”
I couldn’t speak from experience, only having been with one woman, but I could confirm that nothing in the world had ever felt like this to me. Compared to being in my sister – my cock sliding inside as deep as it could go – heaven would be a dim, dull place.
Finally, I felt myself bottom out. I looked down at where we were connected. My dark pubes sprouting up over her bare lips. My cock, angry and purple, sheathed in her pink snatch. We were two separate beings become one. Siblings, connected in the one way we weren’t allowed.
Darcy gave me a nervous smile. “OK?”
“Amazing,” I said.
“Let me set the pace,” Darcy said. She lifted slightly off my cock, then settled down. As she did, her whole body stiffened, and her eyes rolled back in her head. My sister’s chest and face flushed. “Oh fffffffFUCK!” she screamed.
My sister slid back and forth. Her snatch spasmed around my dick. “Oh fuck. Oh fuck. Oh fuck,” she said. Her fingers clenched white on my arms. “Oh wow oh wow oh wow.”
I realized I was going to have to completely recalibrate my Darcy Orgasm Scale. What I’d previously labeled as a DOS 10? That was more like a 4. 5, at best. And we weren’t even really fucking yet.
Darcy leaned forward, her hair a silky curtain surrounding us. She kissed my lips. Nuzzled my nose. My sister came again, and I started to wonder if I should dial 9-1-1 now or wait till she was done.
“You OK?” I asked.
“Holy fuck,” Darcy said. “I mean, holy FUCK. You know?”
