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