Carmen pressed a few buttons on her special baton in a sequence and each woman felt a sharp, sudden heat and tingling sensation in their breasts.

"No! Not again!" whimpered the Wasp.

"What is-" cried Invisible Woman

"Uhhhhn!" moaned Power Girl as she suddenly fell forward onto her knees.

Each superheroine suddenly had their tits explode outwards, doubling in size within seconds. The already busty ones like Wonder Woman and Power Girl now looked absurd and obscene with tits bigger than watermelons, barely able to even stand up without their powers. Girls with smaller chests like Wasp, Cassandra Cain and Squirrel Girl gasped as their boobs shot up to DD-cups with big plug-like nipples. All the others moaned and gasped as their newly huge boobs rubbed up against the bathroom tile and the bodies of the women around them. Not only was their size increased, their sensitivity was magnified as well! Each nipple felt like a clit, as a moaning Fire and Ice found out the hard way when their tits smashed into one another's.

Wobbling slightly and off-balance for the first time in her life, Cassandra Cain tried to close the distance between herself and the guards but she was too late.

"Oh, almost forgot - you get double, Batbitch!"

The surge of weight on her chest hit just as Cassandra was about to leap at Bonnie and steal her baton, causing the Asian girl to slip and have her now gigantic tits pancake beneath her on the wet tile floor with twin meaty slaps that sounded like gunshots in the tiny shower room.

"UHHHHNNN!" groaned Cassie as her giant nips and huge titties registered the impact, making her see stars. On her petite Asian frame, the two giant jutting globes beneath her made it look like she'd landed on a pair of tan beanbags.

"Let's see you try to fight again with boobs bigger than your head, slut." sneered Carmen.

All the nearby supervillainesses cheered and hooted at the state of the superheroines.

"All right, settle down! Shower time's over!" Bonnie added after snickering herself. "You can all check out your girls later. Time for . . ."
