rule 34.66

If it exists, there is a m/m story about it on a fanfiction site.

Diabetic 210-pound teenager named Bree: "I don't get it, how can we write a m/m on this touching story about how two lesbian women overcome their emotional shortcomings to embrace true love?"

Fifty-year-old woman who's never had sex: "We do a crossover with Harry Potter where they get accepted into Hogwarts and drink a gender-shifting potion that turns them into guys, and then we have Malfoy and Snape drill them in the ass while they jerk each other off."

Bree: "Of course! And after that we can add in the magical bondage chapter! How could I ever have doubted rule 34.66?"
