Lick her asshole, stick a finger in, oil her up, and maybe fill her up with a butt plug; just get her prepared. It certainly was extremely erotic, and I felt aware of my entire body as an erogenous zone. Nervous first-timers should start with plenty of foreplay, take things very slowly, and use lots of lube. The moral of the story:
She's obviously horney as heck. Think you might want to satisfy her. Otherwise let me give it a try.
Love that he squirted her right in the face.
