Here is a roundup of a few fanfics I've posted to Ao3 that are relevant to your interests. Thanks muchly to lar_laughs, frea_o and shenshen77 for their beta work on the various fics.

Parenthood is Hard
Rating: R
Warnings: Swearing, Graphic violence (adult on adult), Brief torture scene (adult on adult)
Word Count: 3,800
Summary: A kidfic I started an eon ago in response to the kidfic Friday.  While Natasha is at work, Clint is forced to defend his child and his home.

A thump from outside his house was the first thing that told Clint something was wrong. He woke abruptly in the chair he had fallen asleep in, the book he had been reading to his daughter still in his hand.

Strength is Weakness and Weakness is Strength
Rating: PG-13
Warnings: Swearing, Minor Violence, Hostage and captor interaction
Word Count: 1,700
Summary: A Supernatural crossover, which someone at this bar prompted (unfortunately I've forgotten who it was, so let me know). Clint and Dean bond while being kidnapped.

“Think they’re coming soon?” Dean asked. “I’m starting to lose circulation in my legs. And if my baby gets hurt while I’m gone, I’m gonna kill Sam.” Clint frowned. He hadn’t thought the Winchesters had romantic companions that lasted for any length of time. Clearly he had been misinformed.

Unnecessary Defense (because we love you)
Rating: PG
Warnings: Swearing (nothing like warnings for making you realize how limited your vocab is!), Minor Minor Violence
Word Count: 2,000
Summary: Five times someone defended Natasha when she didn't need it, and the one time she did. For cybermathwitch, who ran the Secret Santa so well.

“Some have criticized the Black Widow and her role on the Avengers team. She’s a spy, not a superhero. And let’s be honest, fellas, while she looks good in a skintight suit, she doesn’t do much damage with those tiny guns of hers, does she?”
