Needing a change (perspective tg)

You're in your room relaxing, when you get a call from your ex-girlfriend Brenda. She wants to talk about why your relationship failed. She says that she discovered that she was actually a lesbian, but loved you still. You're surprised, but it makes sense, she became distant towards the end of your relationship. She tells you that she needs to make a change and will do anything it takes to be with you even it that means sacrifices need to be made. You are confused as to what she is talking about especially when she starts talking about magic.

By some unseen force, you are pulled into midair and held suspended there. You feel your body, mainly your back, crunch as you shrink in height to about 5'3. Your black hair begins to lengthen and your face begins to reshape giving you a more feminine look. Your arms and shoulders become a lot more feminine as well. You panic, and as you breath rapidly in and out, you feel breasts beginning to sprout up until they stop at a b cup.Your stomach becomes more toned the fat from your stomach i pushed down to your ass which becomes rounder and more cushioned. Finally, you feel a sharp tug as your genitals are pulled into your body and you have a new set of female genitalia. Your clothes alter as well. Your t-shirt morphs into a long sleeve teal cardigan sweater. A white lacy bra appears and wraps itself around your perky breasts.  Your jeans change to a brown color, move up your legs, and split leaving you in a very short skirt. Your boxers shrink until they are a pair of black and white striped panties which hug your plump butt very nicely. You look at your new body in shock and let out a very girly scream. Suddenly, you hear a door open and your mind alters. You realize that it must be your boyfriend Brandon home from work. You get on all fours on top of your bed. You present your round ass to him an say, "hey babe i missed you." "I missed you," he replies, unzipping his pants as he prepares to take you from behind
