I hesitated once we got to Kylie’s bed, but she fell back and dragged me right along with her.
“Your sheets,” I said with some vestige of responsible thought.
“Fuck ’em. I’ll get new ones.”
Then she was kissing me again. My worries about the disaster zone we’d make of her bed fled from my mind as I hungrily kissed her back.
I held Kylie, rubbed against her, and ran my hands everywhere. My hips thrust of their own accord, trailing slick precum over her panties. Her underwear was so wet from our mutual arousals that I had some trouble actually getting them off her.
We fought her panties together to slide them down her legs. She finally kicked them off, then lay back with a nervous but excited smile.
There was no question anymore, not by either of us. We’d denied ourselves for too long. I kept thrusting, and without panties in the way, my cock quickly found its way.
Kylie whimpered softly as her pussy lips were parted and the head of my cock just barely pushed inside her. She pulled at me, her fingernails digging into my butt as she physically urged me to keep going.
Her pussy opened up for me as I went deeper and deeper. She was as warm and wet as I’d imagined, and small flexes of her inner muscles rhythmically tightened her around me.
I had to move in sync with her, following her body’s cues, but nothing was stopping me from getting fully inside. I growled in animalistic victory as I bottomed out in my big sister’s sweet little pussy.
I froze with my cock fully buried in Kylie. I thought she was crying into my shoulder. There were indeed a few tears streaking her cheek, but they had nothing to do with sadness, fear, or pain. She caught my expression and smiled back at me with misty but still vibrant eyes. She kissed me softly, tenderly, and with a simple reassurance of love and joy.
We moved together, our hips beginning a slow dance back and forth. She whimpered again, but it transitioned into more of a pleasurable moan. Her pussy tightened around me at irregular intervals, eliciting very similar sounds from my throat.
I fucked Kylie harder, surrendering to my lust and need for her. One of her hands went to the back of my head, stroking my hair as she nuzzled and kissed my neck. The harder I thrust into her, the louder and deeper her moaning became.
“So good,” I whispered.
“Mmhm.” She kissed my cheek, trailing up to my earlobe that she gently nipped at. “Sooo good,” she concurred at much the same volume.
We writhed around, always moving, always grabbing and touching and kissing. Kylie rolled me over and got on top for a while. I loved the fire she displayed riding me so energetically, and way her breasts moved when they weren’t pressed to my chest.
I played with Kylie’s tits with one hand while rubbing the other up and down her lower back. She growled deep and low, then rolled back over.
“More,” she urged. “More.”
She was sweaty and flushed, as I suspected I was as well. Our breathing was ragged and only allowed for shorter kisses before air breaks were needed.
I was going to cum very soon. I’d lasted longer than I expected already. Everything about my sister made me want to explode, to fill her up with my cum. Every single touch, every sound, even just the way she looked at me with those perfect, glistening eyes.
