Pleasant surprise (Part 1)

Timothy had been leaning over the balcony in his apartment when it started. It first felt like his clothes were shifting all around him, but then he realized that it was his entire body! He first felt his jeans slowly slide up his legs, shifting from a loose pair of pants to tight shorts. As they went up, the skin revealed became smooth. His arms as well, both became thinner, but his butt actually popped out a little -- his chest as well! Hair started tickling the sides of his face and then his shoulders. His t-shirt turned pink. Timothy could only marvel at the changes, giving his new bottom a quick feel. A sudden tingle in his crotch -- unlike the rest of the transformation this part was a little painful -- and he knew that he had fully become a woman.
