Gals read and enact sex requests from readers via letters. For example, Samantha Sterlyng is requested to do an anal. So, with the help of Tyler, she does an anal. Simple as that. We should wish that all girls were that easy.
This is the way of the entire tape. Six scenes range from romantic couples to girl/girl to revenge on boyfriends who cheat. A feeling of elegance prevails which, often combined with anal, is a feat unto itself.
