PRETTY MAIDS All IN A ROW: High School [Teen] Student Fisted By Her Teacher

Pretty Maids All in a Row, Francis Pollini's novel and Roger Vadim's film, is about Tiger [Rock Hudson], a charming Ocean Front high school Civics teacher, who kept a rotating list of nymphets whom he had sex with in his office. However, once his students became too attached - he killed them.

We've written about the rise of anal sex among teens in fiction and non-fiction. For example, the protagonist in the novel Innocents had anal sex with one of his high school students; however, that may pale in comparison to what Tiger did to one of his students in Pollini's novel. 

In the novel, Tiger picked up "fresh, sweet" smelling Rochelle, a 17-year-old junior (The affair started when she was a sophomore), in his car and drove her to a: "[...] nook completely screened from the road [...]".  Soon after he parked the car he: "[...] glided into her trembling body [...]".

"Now My Tiger-" She gasped and said, trembling more and more. 
"Alright, Lovely-" Tiger said, withdrawing his shaft...
"Now Lovely_" She gasped...
"Wow, Lovely-" He told her, making his hand into a fist and easing it between her divine thighs, and upward, slowly, ever, deeper, seeking her, as she groaned, and moaned, trembling violently-
"Yes, YES LOVELY-" She said- His arm was gliding, penetrating, he was almost up to his elbow, he was drenching wet...

That's correct. The high school Civics teacher fisted his 17-year-old student.
