"I know!" Karyn said jerking the Role Exchanger from Jon's hands. "I can finally fix my breast problem."
"But wait..." Jon started.
Karyn took the gun, selected both of their chests and fired.
Soon Jon's shirt was very tight against two large round mounds, while karyns top slowly deflated.
"what I was going to say before you fired." Jon said "was it will NOT work that way, the size would swap but not the roles, their properties will remain the same."
Jon put his hand up to his strangely firm and muscular feeling but feminine looking breasts which needed no support. Karyn lifted her shirt and found two small slightly hairy male pecs which felt strangely heavy and bounced and jiggled with every move like breasts would.
