You run into the bedroom.

"Erin, please don't!" Samantha cries then you hear another slap and then a body falls on the floor, followed by weeping.

"Did you fuck guys while we were still together, you fucking bitch?" Erin yells.

"No..."

"You fucking liar!"

"No!" Samantha screams.

You cannot take it anymore and stand idly by while your new roommate and lover gets assaulted by her ex-girlfriend. You throw aside the shower curtain and rush into the bedroom, startling the buxom blonde that is straddling Samantha's belly. You grab Erin's raised hand and pull her off of Samantha.

"Who the fuck are you?" Erin screams after you pin her facedown on the bed.

"Craig," you reply calmly, glancing over to see if Samantha is okay. The redhead nods and smiles weakly at you.

"Get off me, motherfucker!" the blonde curses, struggling to free herself from your hold.

"Calm down," you say in a gentle voice despite wanting to smack Erin for abusing Samantha.

"Fuck you!" Erin shouts. "You're the one who fucked her, you fucking bastard!"
