There's a story at Twisting the Hellmouth called 'Five times Dawn and Sam had hot, dirty sex (and one time they didn't)'. Apparently it's a 'Supernatural' crossover but I have zero interest in 'Supernatural' and so I haven't read it. However to me 'Sam' automatically means one of several far more famous fictional characters and therefore, on seeing the title, I jumped to some rather different conclusions. This is the first of a series of 6 drabbles based on my erroneous assumptions. 100 words, rating R or maybe NC-17.
Five times Dawn and Sam had hot, dirty, sex... and one time they didn't.

Dawn sank down from her knees and then rolled over onto her back. She reached up her arms and pulled her lover down to lie beside her. His head rested on her breasts, in the perfect position for some post-coital licking and nibbling of nipples, and his toes brushed against her knees.
“That was pretty damn good, Sam,” she said, once she had regained her breath sufficiently for coherent speech, “but why do you always have to finish off with anal?”
Sam blushed. “Sorry, Mistress Dawn,” he said. “I got used to it while I was with Master Frodo.”
