That was all I needed. I pushed my finger all the way into her little anus, and slowly began to fingerfuck her ass.
Here she was, across my lap, her buns red from a spanking, her fingers buried in her pussy while I fucked her little hole with my finger. She was bucking and making sounds I had never heard before. It was just amazing.
My cock was close to bursting from her grinding, and I suddenly pulled my finger from her widening little hole. She groaned and turned her head towards me. She seemed almost frantic, as I moved her hand from her pussy and lifted her up so she was standing in front of me. I put my hands on her hips, guiding her so she straddled my legs. She looked down at my cock, which now was able to stick straight up in the air, reddened from the friction from her stomach. Then she looked at me, and a small smile appeared across her face as she scooted forward, and in one downward movement, impaled herself on my cock.
We both let out a loud groan, as her little red bottom contacted my legs. “Oh my God!” she gasped again, as she wrapped her arms around my neck and buried her head in my chest.
Still holding her hips, I lifted her up and brought her down again and again, burying my cock deep into her center. She cried out. I felt the waves of her orgasm, as her body shuddered, and her wetness trickled onto my legs. I exploded with a release that was overwhelming. My come mixing with her fluids. ‘La petite morte’…the little death.
I woke the next morning, naked in bed, spooning my naked sister. My left arm was wrapped around her, and she held my hand against her left breast as she slept. I could feel the steady rhythm of her breathing. I felt bathed in a complete sense of calm and contentment. I dared not move, for I did not want to end this perfect moment.
Then I thought of what we had shared the night before. The magnitude of our coupling was beginning to sink in. There was no turning back, and I was at peace with this.
Then, I felt my cock awakening. It had been safely nestled along Linda’s beautiful backside, laying peacefully between her ass cheeks, still a bit red from the night before. It began to grow. A beautiful woman, totally naked, a breast in hand, my cock just inches away from her womanhood, was a dangerous mix. The more I focused on my cock, telling it to stay still, the more it grew. I had no control.
Then Linda squeezed my hand that rested on her breast. “Mmmm…I think someone is getting awake,” she said. Then she slightly pushed back against my expanding cock.
“Sorry, my love. I just cannot control it,” I whispered. “Did we cross a line last night?”
“No, we blew right by any line, if there was a line,” Linda said, as she began to slightly wiggle her hips. “We both got naked, you spanked my ass as I rubbed my little pussy, then you put your finger in my bumhole, and finally we fucked. Yep, I think that was a line,” she giggled.
I gently kissed her neck. “You know I love you, don’t you?”
She moved my hand from her breast and kissed my palm. “I love you, big brother. I have always loved you.”
