Fresh silk sheets cool against hot skin in cumming with my sister. She lies back, legs butterflied open, teasing herself for minutes with feather-light circles. “cumming with my sister,” she sighs, “please cumming with my sister.” The slow torture builds until she finally shoves four fingers inside, screaming “cumming with my sister!” over and over. Her whole body convulses in the longest, wettest orgasm yet, soaking the sheets with endless “cumming with my sister”.
