Jeff suddenly felt very itchy, as his skin slowly became smoother and darker, until it took on a grayish black tone.
"Amy, what did you set it to?" he asked his girlfriend, filled with worry.
"Oh, something fun, I assure you." she winked at him, as his knees gave in to his weight with no warning whatsoever, and his entire body felt weaker and weaker.
Jeff's muscle fibers were untangling and reforming as fabric, knitting themselves into new tissue. Understandably, this process drained him of all of his strength, and he dropped to the floor face-down, completely exhausted. Using what little energy he had left, he pushed himself and rolled over so he'd be lying on his back.
Amy was standing over him, looking down at him as he gasped for air with a mischievous smile on her face. She kneeled down and put her hands on his cheeks, making eye contact.
"Don't worry, sweetie, I promise this will be worth it. Just trust me on this one, okay?" she said softly, and gave him a kiss.
Jeff couldn't react. He had noticed that Amy was slowly getting bigger and bigger, and realized it was probably him who was actually changing size. Even more, he felt as if he was becoming hollow, with no traces of inner organs, getting colder every second and becoming more like some sort of deflated cloth pile.
His girlfriend then grabbed his hands and put them together over his chest, and he saw as his fingers began interlocking and melding together on their own, unravelling and reforming both of his hands, no, both of his arms into thin pieces of fabric. It was such a strange thing to see that he completely missed the disappearance of his legs into his torso. But when he finally noticed, something else happened.
Amy was now sitting, looming right over him, and Jeff tried to look at her, perhaps seeking some sort of answer, but the only thing that caught his eyes were his girlfriend's boobs, hanging right on top of him, shapely and perky as ever. The sight took him off guard, causing him to exhale what little air remained in him. However, when he tried to close his mouth, he found out he couldn't anymore. He also realized that it seemingly becoming wider and wider relative to his shrinking size.
As Jeff's entire body became smaller, flatter, and more and more elastic, his mouth retained a bit more consistency, but as it morphed it also began to alter the rest of his face. The size of his maw was so great it probably occupied the most part of his head, and all the other features in it slowly begun to be smoothed out, his eyes last, so the last thing he saw were his girlfriend's breasts, before going completely blind.
Finally, he felt as what remained of his cheekbones slowly developed into the shape of two large cups, and then as quickly as the effects had begun, they came to an end.
Amy picked up the piece of clothing that was now in front of her and held it up before her.
"Heeyyy, how are you feeling, Jeff?" she asked, as she carefully pulled on his now sports bra-shaped boyfriend, testing his elasticity.
Jeff, utterly confused, tried responding, but in this new form he was completely incapable of speech.
"Oh, right! It's not like you have lungs or anything now. Well, guess what? I turned you into a sports bra!" she giggled with excitement.
Upon hearing this, he tried squirming a little, to no avail, but suddenly he became aware that, while not exactly seeing, he was somehow perceiving his immediate surroundings. He could perceive Amy holding him, as she stood before him, and he could not only get her words, but also get a good "look" at her very attractive body. For a moment, Jeff smiled at himself smugly, proud of having such a hot girlfriend. But then, he realized what "being a sports bra" actually meant.
