He's a Big Girl Now (Patreon)

 Kokonotsu Shikada woke up one morning to find his vision terribly blurred.  He stumbled his hand across his dresser, despite feeling like somebody put two massive balloons on his chest.  His hand felt a pair of glasses, which he put on immediately.  In the dark, he had difficulty seeing his feet, which were hanging off the edge of the bed, because of two massive mounds on his chest.  Kokonotsu lurched out of his bed and spun around to the mirror, feeling his shorts biting into his skin as the flesh of his thighs and hips bulging into the only clothing he was wearing.  He couldn't believe what he saw in the mirror!  It was  Hajime Owari, his co-worker from the  Shikada Dagashi Shop!  Except, he was she.  He could only wonder if the real Hajime had woken up to similar situation.
