Jennifer’s warm nether lips wrapped around my cockhead. Already, I had to resist the urge to shove myself all the way in. I made myself lie back, let my sister slowly gorge her hungry pussy on my dick.
The head was all the way in. Jennifer’s face cinched with wonder and discomfort. Down to my shaft. About halfway. My sister’s mouth and eyes wide open. A little gasp and groan. Almost to the bottom. Our pubic hair tangling. Now both of us completely connected.
Jennifer stilled. She put her hands on my stomach. Eyes tightly shut.
“You OK?” I asked.
“Just. Getting used,” she said.
“You feel amazing,” I said, “So warm and tight.”
Jennifer’s eyes popped open. “I’m not on birth control,” she said.
I waited for the ‘s-word’ to tell me if this was real. She didn’t say it. The worry in her eyes looked real enough though.
“I can go get condoms,” I said, “The Rite Aid is 24-hours.”
“No, I want to feel this,” Jennifer said, “Feel you.”
“I’ll pull out,” I said.
“You’d better,” Jennifer said. I still wasn’t sure if she was playing around. Oh God, how had we gotten ourselves in this situation again?
I wasn’t able to think about it any longer though, because my sister started to roll her hips on my dick. I put my hands on her thighs, but I let her control the motion. Her mouth hung open. She started to breathe heavily.
“You’re fucking your own sibling,” I told her, “Bareback with your brother.”
“I know, so good,” Jennifer said.
“It’s incest,” I said, dragging out the word, “It’s wrong.”
Jennifer only moved faster. She dipped her hand into her crotch and rubbed her clit.
“You gave your virginity to your brother,” I said, “What kind of girl does that?”
“Yours,” Jennifer answered, “Your girl.”
“That’s right,” I said, “You’re mine now. Forever. I own you.”
“Please,” Jennifer said. She was full on thrusting now. Bouncing up and down on my dick. Tits flying everywhere. Grunting and mewling like an animal. Like a girl gone out of control.
I grabbed my sister’s ass — those cute, rounded buns — and began pumping into her. Our rhythms matched like we’d been lovers our whole lives.
Jennifer’s eyes popped wide. She sucked in her breath. Her whole body went taut and I watched, rapturous, as my sister orgasmed on my cock. I looked down to see. Sure enough, her toes were trembling.
My sister fell forward, gasping for breath.
“Holy fuck,” she said, “I mean… holy fucking fuck.”
“Good?” I asked.
“Amazing,” she said, then kissed me hard on the mouth. “You didn’t…”
“I told you I’d pull out,” I said.
“Right,” Jennifer said, “I guess I didn’t edge you enough.”
“Just enjoy it,” I said.
Jennifer began to sit up, then collapsed forward again. Her whole body limp. I wrapped my arms around her and rolled over. Somehow, we stayed connected.
“Are you going to fuck me now, brother?”
“I’ve been fucking you this whole time,” I said.
“That was different,” Jennifer said.
I shrugged my shoulders. I didn’t really get it, but I wasn’t about to argue with the woman whose cunt was wrapped around my cock.
I drew back and then slid into my sister. Kept my hands on her ass as I pumped. My rhythm got faster. Our flesh slapped together. I pummeled her into the bed.
“See,” Jennifer said, gasping out each word, “This. Is. Fucking. Me.”
I responded by going at her even harder. My balls bounced off her bottom. Our bodies both soaked in sweat. The bed cried out in pain with every thrust. My sister groaned and gasped.
I wanted it to last forever. I could feel the end racing forward. I hadn’t had intercourse in years. I hadn’t had release in weeks. My sister had teased me the whole drive home. Whatever was coming, it was going to be massive.
“Getting close,” I warned my sister.
She grabbed my head, stared into my eyes. “Cum in me,” she said. Whined. “Please.”
“Are you sure?” I asked. Waiting for that one magic word. She never said it.
“I need it so bad,” Jennifer said, “I want it inside.”
“But you’re…”
“Fill your sister. Stuff her up.”
I really wasn’t sure what my sister wanted. But I didn’t stop fucking her. If anything, my speed only increased.
“Put your baby in my belly. Knock me up,” Jennifer said, “It’s OK. I want it. Want you. Show the world what a slut your sister is.”
“Jennifer,” I said. It was my last warning.
“Cum in ME!” My sister cried.
I buried my dick as deep as I could. A moment later, an absolute geyser of sperm burst out of me. Pump after pump of precious fluid in a stream that was more like a tidal wave. An unending font of fertility that filled my sister so fast I could already feel the warmth of it dripping back out of her.
Jennifer’s eyes went wider than I’d ever seen, then rolled back in her head. Her legs wrapped around mine. Then my orgasm overtook me, and I couldn’t see anything. Only revel in the bliss as it blasted through me.
