“Ugghhhh shit, it’s so fucking big!” she cried, placing her hands on my abdomen for balance as another inch slipped inside.
“Don’t force it, sweetie, just let your pussy adjust to the size first,” mom advised.
What I was witnessing was so surreal. Mom was kneeling next to Sherri, her left hand cupping my sister’s tit, while her right hand was kneading my balls. Electrical currents flowed through me as I watched the determined look on my sister’s face as she tried to take all of my cock up her cunt. Fascinated I watched her pussy slide up and down my slick shaft, her inner labia sinking in then clutching my shaft on the upward stroke. I knew that if I kept watching I’d shot off like a roman candle. I had to distract my mind if I wanted to prolong the inevitable. Reaching out I slid my hand along mom’s flank then over the round cheek of her ass that I was able to reach.
