Title: Nothing Happened Author: @thistlecatfics Ships: Alphard/Sirius, Sirius/James Rating: M Wordcount: 8k Significant warnings or tags: Underage, grooming, noncon (not explicit), substance abuse, homophobia, misogyny, self-harm Summary: 

Alphard takes an interest in his nephew. 

Title: A Proper Education Author: @yieldmaiden Ship: Alphard Black/ Sirius Black Rating: E Wordcount: 11k Significant warnings or tags: Uncle/Nephew Incest, Explicit Sexual Content Summary: 

Alphard hates that it has to be him who teaches Sirius about physical love, but Orion has made it entirely clear that if he refuses, someone else will take the part, and most of the Blacks would forget the “love” part over the “physical” and leave his favourite nephew inevitably scarred.

Title: Inside Dogs Author: @zoemillinwrites Ship: Sirius/Regulus Rating: E Wordcount: 16k Significant warnings or tags: Muggle AU, Suicide Attempt, Self-Harm Summary: 

There in the great outdoors, the gathering Appalachian dark, Sirius invents a new game they’ve not yet played. The rules are clean-cut. Regulus catches on quickly because he’s smart and because he trusts implicitly that Sirius knows best.

“It’s called Grim Reaper.” Sirius barks out a laugh, beckoning Reg in close. “Grim for short.”

Regulus hmms and rubs at his bare feet.

“You run,” Sirius lifts his two long, teenage, knobby fingers and flicks them back and forth like a set of miniature pumping legs. “If I catch you, you have to kill yourself.”

“For real?” Reg deadpans.

Sirius is so idiotically endeared by the sarcasm that he ducks his face to disguise his grin. “No, you stupid idiot. Not really. Just pretend.”

“Oh.” A dutiful pause. “Okay.”

A starcest hunting AU.

Title: (Not) Forever Author: @emmalouisefanfiction Ship: Andromeda/Narcissa/Bellatrix Rating: Explicit Wordcount: 2k Significant warnings or tags: Underage Summary: 

She loved her sisters more than anything. She’d been taught to value her family over everything else. Their blood. Their purity. And the best way the Black sisters could show it was to embrace it. To embrace each other. No matter how forbidden. How mad. Or how temporary.

Title: Her Gaze, Unbroken Artist: @digthewriter Ship: Nymphadora Tonks/Bellatrix Black Rating: G Medium: Digital Art / Mixed Media. Photoshop.  Summary:
