I always ask her three questions before sex.

Who are you?

How old are you?

Yes or no?

For a while, the answers were fun but simple. I’m a nineteen-year-old student in your college English class and I’m going to seduce you no matter what. Possibly she was my twenty-two-year-old intern and this time she wanted to struggle. And on and on we went, finding fun scenarios that made our nights full and tender.

And then, one night, I crawled into bed to find her naked under the covers. There was one candle flickering on the bedside table and the room was quiet.

“Who are you?” I whispered as I wrapped my arms around her naked body.

“Don’t be silly,” she said, rolling to her back and pushing me away. “I’m your little sister.”

I sat up and looked at her as if seeing her for the first time. She was nervous and adorable as she covered her breasts with her arms.

“How old are you?” I whispered.

“You know how old I am, stupid. I just turned fifteen.”

“And why is my baby sister in my bed? Are you looking for something?” I asked, the final question hopefully clear.

“No,” she said, shaking her head back and forth. “Now leave me alone or I’ll tell dad.”

Two seconds later I pinned her arms above her head as I climbed over her. She struggled beneath me as I forced her thighs apart with one knee.

“You won’t tell anyone,” I growled, holding her wrists with one hand as the other slid down over her naked body. “How would you explain that you’re the one naked in my bed?”

“Please,” she moaned, closing her eyes each time I squeezed or pinched her. “Just leave me alone.”

“I don’t think so, Sis. After all this time, I think I want something else. After all, it’s not every day I have a pretty little girl in my bed.”

“What are you going to do?” she asked, looking up at me. Both of us were still as we looked down to see me hard against her soft smooth skin. My cock twitched up and down as we watched, and then I kissed her mouth until it hurt.

“I’m going to fuck you,” I said, reaching between her legs.

“Please don’t!” she moaned.

And then I was inside her, fucking her harder and harder as our little dream world filled both of our minds. I slapped her and pushed her down, fucking her faster as she struggled beneath me, all the while pleading with me to leave her alone.

And then, after long thrusts, hard bites, and her cunt clenching around me, she said the words that she knew would work just right.

“Please,” she begged again. “Whatever you do, just don’t come inside me.”

I was done before the words had left her mouth, and I pinned her down once more as I buried myself in her, feeling my release.

“Fuck sis!” I yelled, holding her down as I came and I came, filling her pussy as she clenched around me and took me in. When I collapsed onto her sweaty body, she wrapped her arms around me and kissed my lips. Tenderly this time.

“God, I love you,” she whispered, her voice on the edge of a giggle.

“Fuck that was good,” I said, rolling next to her and parting her thighs again with one hand.

I took a deep breath, smiled, and then opened her wet cunt with strong fingers.

“Now it’s your turn, sis.”
