Rachel was still fingering herself when her Adam's Apple finished growing and the remains of her breasts formed manly pecs. Her feet grew from a women's size 8 to a men's size 12, losing their female softness. Her hair had shortened into a normal males haircut, and her face had already become a male version of itself, complete with stubble and the beginnings of a mustache. Rachel had grown several inches taller, almost making the 6 foot mark. She was now completely male, except for one small detail.
Dawn had watched the entire transformation in awe. Rachel was her best friend, and she had never thought that she would ever be turned on by her, but now...she couldn't help herself! Rachel had become a hunk, mostly, and Dawn couldn't contain her lust. She quickly undressed and got down on her knees. Rachel still had a pussy, but other than that, she was completely male. Dawn knew, based on everything else that had happened to Rachel, that the transformation WOULD finish, so she pulled Rachel's hand away from her pussy and placed her face between Rachel's hairy legs. She licked Rachel's clit, which seemed the swell outward in response, and then began sucking on it. She tickled it with her tongue, and it continued to grow. Dawn could feel Rachel's labia push outward against her chin, and realized that her transformation was almost finished. Rachel's clit continued growing, becoming mushroom-like at the tip. It grew bigger and bigger, until finally, a hole opened up at the tip. At that moment, Rachel's brand new balls dropped into position, and she orgasmed, filling Dawns mouth with cum. She quickly swallowed it, enjoying the warm salty liquid, and then looked up and into Rachel's eyes.
"Don't stop...It feels too good..."
"I've got a better idea." Dawn said as she crawled on top of Rachel, placing her newly formed throbbing penis into her pussy. Dawn could feel it throbbing inside of her as she started to rock back and forth, thrusting Rachel's penis in and out of her pussy. Rachel raised up her arms and started massaging Dawn's breasts, and she began moaning aloud. They both closed their eyes as the pleasure began to grow in intensity. As Dawn thrusted, the pleasure clouded both of their minds. Dawn didn't notice that Rachel's dick still seemed to be growing, and Rachel didn't notice that Dawn's breasts shrank as she rubbed them...
