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