Nightmare Moon smirked, her cheek was pressed into her fist. The mare’s eyes looked down upon the night princess.  
“It’s so wonderful to see you again… how long has it been?” Nightmare Moon asked. Princess Luna looked away from Nightmare Moon’s hooves, her gaze settled upon the stone floor.  
“I know you’ve missed me… You’ve longed for the power I gave you…” Nightmare Moon spoke softly, her words were laced with vile honey. “You were always SO accepting of me. Come…” Her hooves hit the floor with a powerful clop. Princess Luna didn’t respond still averting her gaze from what she considered a mistake.  
“I don’t need you. I make a mistake back then and I shall not repeat it again!” Princess Luna at last spoke directly to her ‘captor.’  
“Yet you do not destroy me,” Nightmare Moon replied as she rose from her throne. She raised a dark hand into the air, clenching a fist.  
“I do not need my full might for you to accept me,” She simply said. Her fist began to glow with magic and a similar aura formed around Princess Luna’s bosom.  
“Wha-” Luna stammered before letting out a blissful moan. Something began to fill Luna’s breasts, she began to lose herself in the pleasure. The sensation pulsed warmth from her nipples to her torso. Quickly Nightmare Moon’s magic made Princess Luna’s breasts grow, bigger and bigger! The princess of the night did nothing to stop Nightmare Moon’s influence as her swelling blue breasts lifted her upwards.  
“We’ll be one soon enough…” Nightmare Moon chuckled.
