Dr Derriere's assistant Stephanie buzzed the intercom. 'Who would you like to see next? There's:
Chastity - an 18-year-old, white, blonde Catholic girl, five foot six with athletic features, B-cup. Her figure is wasted on a religious girl. She is worried about sex before marriage, unprotected sex, and displeasing God.
Vina - an 18-year-old Thai girl, petite, five foot one, with small breasts. She is dissatisfied with her sex life yet she is in control of it at all times: her boyfriend always asks her consent, and lets her choose when they fuck, and how. She can't understand it.
Arwen - a glasses wearing, geeky, ebony 18-year-old straight-A student. Five foot seven, larger than average breasts. She's a good girl who has never failed at anything, except ass fucking. She needs to train her ass for her boyfriend but doesn't know where to start.
Riley - an 18-year-old self-professed slut. She's had half the soccer team, and her stepdad. The perfect white, blonde, cheerleader body, C-cup breasts and tight, firm stomach and legs, five foot five. Very flexible. She can't stop sticking things in her ass. What's wrong with her?
Tiffany - a petite, four foot ten, 18-year-old gymnast who wants to improve her core muscle strength in order to improve and get into the Olympic team. She's tried everything her coach has suggested, but keeps getting knocked back. She's looking for a miracle.
