A little bit of background for those who asked. I struggled a bit with this so may tweak it later. As before please be wanted that this has non con/reluctance.

Things hadn't always been like this. Bree was born three years after Alex and had adored and hero worshipped him from the start. Once he'd got over the disappointment that she wasn't a boy little Alex had initially tolerated, then fiercely loved her. They'd always been close. He'd always been protective. But all in the normal way. Then their parents passed unexpectedly in a car accident and everything changed.
She'd been 18 and he 21 when it happened. Alex was recently graduated and just months into his new job. They'd both been devastated but he'd stepped up, moving her into his apartment and ignoring the well meaning but unappreciated offers of uncles and aunts to take Bree in instead.
The first few months, year really, they'd both floated in a state of grief and trying to adjust to the new way of things. They hadn't lived together for the three years Alex had moved away to college and in a way they were getting to know their adult siblings for the first time.
Bree took a year off from school but eventually went back to complete and graduate from her final year then begin the daunting task of college applications. Still everything remained relatively normal between them.
The first hint of trouble occurred on a sunny Saturday afternoon in the summer before Bree began college. She'd come back exhausted from a morning swim and collapsed on the sofa in her bikini and an oversized white shirt she wore over it.
Some sense of awareness caused her to open her eyes perhaps hours later. She started to unexpectedly find her brother standing silently by the sofa looking down at her.
His normally fastidiously tidy dark hair was in disarray and his brown eyes were bleary and unfocused.
She placed a hand over her rapidly beating heart and said "oh you scared me Alex!"
"Shut up" he replied tersely.
"What's wro-"
"I. Said. Shut up." He was gritting his teeth at this point and seemed to be staring at the hand on her chest with a singular focus.
Alex had never spoken to her like this before and Bree was confused and more than a little hurt by his behaviour. But she was scared too and remained silent.
He continued to stare at her hand while breathing heavily, until after a while he seemed to come to himself and drag a palm over his face while shutting his eyes.
Bree had the sensation of having barely skirted away from some danger. With her relief came the awareness she could smell alcohol over the overbearing chlorine that clung to her clothes.
"Have you been drinking?! It's 2 in the afternoon Alex! What the hell?" Oh how she'd wish later that she'd stayed silent.
"Which part of shut up don't you fucking understand?"
Bree was completely and utterly stunned now "I-"
"I work all day, everyday, to make sure we're fed and clothed and you can spend your days lounging around on my sofa barely dressed. I think I've more than earned the right to drink whenever I fucking feel like it" all this was delivered with a snarl and flashing eyes.
"I'm sorry i didn't realise things had been hard! You should have said I would have helped!" Bree shouted.
This was met with a derisive snort.
Bree was getting angry now. "I would have! So don't go getting angry at me for something I couldn't change" she snarled back.
Alex looked thoughtful at that and a little calmer. Bree relaxed back on the sofa with a sigh.
