Mark had an extensive collection of 16mm porn movies that he treated like sacred film archives. His projector was straight out of a football coach’s war room — slow motion, stop-action, instant replay, the works. One Saturday night at a small party, once everyone was sufficiently shit-faced, Mark fired it up and played a feature on cunnilingus and fellatio. He kept rewinding the graphic scenes as if he were dissecting the Zapruder film. Rita watched, utterly fascinated, as she’d just discovered a new branch of medicine.
On the walk home, Rita was giddy and buzzing. She bumped my hip and asked, “So why don’t you eat my pussy like that?”
“I rub my face in it!”
“Yeah, but you’re not using your tongue. You’re not attacking the labia or hunting down the clitoris like those guys. I’m not complaining, but we still haven’t had an orgasm from your dick yet.”
“Rita, I’m sorry — I swear I’m getting better...”
She slipped an arm around my waist, stood on tiptoes, and kissed me sweetly. “Honey, I’m not criticizing. I love the orgasms from your fingers and from rubbing one out while we kiss and you maul my tits. But after that movie? I want one from you actually eating my pussy.”
“Fine, I’m in,” I said. “But you’re trimming that wild bush first. I refuse to floss with your cunt hairs. And fair’s fair — I want a blow job exactly like the blonde gave in the movie. I want to finish in your mouth.”
It was past two a.m. when we got home. We both knew Sunday studying was coming, but horniness won. We stripped naked. Rita sat on the toilet like it was spa day while I grabbed a comb and scissors for her emergency landscaping.
