Those vibrations of her orgasm were all it took to send me beyond the point of no return.
My left hand moved of its own accord up her chest, then down her arm and along her ribs until I had one cheek of her ass in my grip, squeezing and sampling her soft and pliable buttock while I pulled her closer to me. I’d given my sister something that I’d never considered before, a mind-shattering orgasm.
