You've been seeing Alex for awhile behind your girlfriends back, but she's gotten extra territorial lately. She really gets off on being a homewrecker. Today she wants you to repeat a mantra as a sort of initiation. Making you all hers. She's going to make you do as you are told, from humiliating your gf to impregnating Alex. Your dick belongs to her now. Take it out and repeat after her, do as you are told.
