"Tom...omigod!" Jace suddenly exclaimed, pulling up from her laying position and forgetting the fact that she was naked. Tom stood up right after her, looking down at his body, half expecting that it would undergo the same transformation that Jace had just undergone. He unknowingly let out a sight of relief when he looked down and still saw his male body. But quickly he realized that something was happening. A dark tan had appeared on his chest, and was slowly spreading out over his body.
"What the fuck," he exclaimed, "He wasn't supposed to paint me. How did he..." Tom thought back to that day in the studio, and remembered that Guillame had taken a few quick photos of his face. But not the rest of him. It became clear as he saw the tan grow a bit darker that he must have given him elements of Jace's body for reference. Before Tom could think things over though, he felt a sharp pain envelope his whole body. Jace could only sit their and watch as his friend curled up in the fetal position and sunk to the floor, before stretching out as if he were spasming.
She watched as his body seemed to elongate before her very eyes, gaining 7 or 8 inches of height in just a few minutes. The dark tan that had built up on his body continued to darken, because a light chocolate brown color. Jace could see the hair on Tom's head darken and become coarser as well, as his facial features altered slightly, his nose flattening and his eyes becoming more almond shaped as he transformed into a black man. Tom screamed again as bones cracked in his body, making way for the more muscular frame that he was getting. His muscles spasmed, and Tom nearly lost his lunch as every nerve ending on his body felt like it was on fire. His legs especially lengthened and added muscle, as his abs formed into a tightly held, almost washboard style 8-pack. His ass became more rounded, but not just from fat, tight muscle all seemed to grow their too. Hair grew all over his body, coarse black hair covered his chest and under his arms in a fine layer. The whole thing was causing Jace's mind to betray her again, as she unconsciously began fingering herself, the process turning her on.
As the pain slowly subsided, Tom began to breath deeply, groaning in pain, as he could hear his voice deepening to a tenor bass tone. He also felt a new sensation growing in his lower abdomen, and could only grimace as he sensed what was coming next. His darkened skin began to envelope his previously untouched cock, and in response it began to grow much larger and thicker. Bigger and Bigger it grew, till it became more than 13 inches fully erect. His balls became like the size of grapefruits, pumping testosterone in overdrive into his body. His muscles responded, growing even larger till he looked like a black Adonis. Jace, unable to control her own urges, laid back down on the couch and continued her own ministrations, feeling another orgasm coming on. Overcome by his own lust, Tom couldn't fight the feeling he had when he saw this, and proceeded a repeat of their previous episode. Jace felt like she might be split in two for a moment with the size of the tool now violating her, but soon enough the pleasure overcame them both, and another explosion of ecstasy and bodily fluids quickly passed.
As they laid their panting, Tom was the first to say something. "What's happening?" was all he could ask, "Why did you become a woman and I became a black man?"
Jace had no answers, but she knew that something more was happening to them. She started to feel queasy, a feeling that Tom felt as well, as the room seemed to spin around them. The queasiness passed, and when they awoke, they found...
