Minka's New Dress (Patreon)

"Do you like my new dress? It has three settings... this is level one," Minka says, posing and twisting in front of you.

"Are you wearing a pushup bra underneath?" you ask skeptically. Your normally small chested girlfriend is sporting what looks to be a nice set of C, maybe even D cups.

"Nope, that's the power of this dress... look, here's level two," she says, whisking out her hair and turning to face you. Your draw drops as her chest begins to balloon out. the fabric of the dress follows suit, conforming itself perfectly to her rapidly expanding breasts which quickly grow larger than her head.

"Wow! What the hell?"

Minka grins, "Can you believe it? These are M cups I think... maybe bigger."

You grab and squeeze her breasts and reach inside her top.

"Trust me, that's all me... no padding. Let's try level three."

Your heart is pounding and you are short of breath as Minka's chest doubles, then triples in size yet again.

"I don't even know how big these are," she says swinging her heavy chest back and forth proudly. "T... U... V cup maybe? Do they even make bras this big?"
