Body Duplicate: The girl next door

...my next door neighbor, Mrs. Higgins." As the words escaped Jon's mouth he could feel himself begin to change. He began to shrink, falling to an even 5 feet as his body lost muscle tone and began to shift into Natalie Higgins's voluptuous figure. His member began to shrink inwards as his chest and butt began to swell, the former stopping at a large dd cup. His hair began to grow longer and turn a light blonde, stopping at the small of his, now her, back. All of the hair all over body fell out as she felt her face began to shift, eyebrows thinning as her lips began to puff out. Jon looked to the mirror to see his neighbor Natalie starring back. As he watched his room began to spin and fade, coming back into focus a moment later in his neighbor's bedroom (now his as well).
As he watched his clothes began to change, his jeans slipping off of him as his boxers began to shrink and turn black, forming the bottom of a thong bikini as his shirt followed suit, quickly turning into a top that hardly covered his ample cleavage. Looking out the window into the back yard he could see Natalie sunbathing in their fence, wearing the same bikini Jon now found himself in. Looking over his new body one more time he decided to join Natalie, suddenly having the urge to get a nice, deep tan.
