Finish the job before leaving.

John wanted to do one thing before leaving, he did enjoy the sex with Seraphina that he just had. But he felt like she needed a punishment, she did treat him very badly. He figured that since she did trust that Mike never really had " a small dick" that everything about it must be one big mistake, he wanted her to match Mike, just for now at least. With a snap Seraphinas tits turned into tiny A-cups, leaving her almost as flat.
