Lightning came across the window from time to time and lit up Kate's face.
Tristan looked directly into her eyes and observed the tiny changes in her expression.
His slender fingers were playing a solo inside her body. A song without sound but with a unique melody was manifested through her breathing.
It was sometimes slower, sometimes faster, sometimes lighter, and sometimes heavier.
As the beats became longer and higher, there was moaning about accompanying it. Something changed subtly inside her body. It became smooth as his fingers went in and out, and it also soothed his irritated heart.
Being separated from each other for so long, their bodies were each attracted by the scent of the other. With slight touches, the flames lit up fiercely.
Kate honestly responded to his motion. The tips of her nerves caught the stimulation and responded to it. A surge overwhelmed Tristan's consciousness and pushed other thoughts out of his mind.
