Megan's new assets

Megan felt the shock, but didn't drop either item.
"What happened?" asked Nick
"It shocked me. Maybe that means it's doing something?" replied Megan. After a moment, her bra started to feel a little tight, then more tight, then a lot tight.
"I can see the difference from here, how're you feeling Megan?"
"A bit constricted."
"Let me help." Nick put his hand up Megan's shirt and undid the bra strap with one had.
"Freedom!" yelled Megan. After a few minutes, she felt the changes stop.
"How do you feel?" asked Nick.
"Like me, but with more neck soreness. Geez these things are huge. Excuse me while I go put this new bra on, cause I need it."
"Can't you do it here?" pleaded Nick.
"...Sure. You are lucky I love you," said Megan as she took off her shirt and old bra. She shook her breasts for a moment for her boyfriend.

She then got the new bra on, but took a little more time than usual.
"That was wonderful, "said Nick
"Now it's my turn for you. Hold the medallion and I'm going to throw something you have to use."
Nick stood holding the medallion, wondering what Megan was going to toss at him. Maybe a bra for revenge? Or maybe that ring they found at the carnival?
