Sonic began to moan lightly in his sleep as his body continued to tingle, and started to change. His ass began to expand, becoming round and tight, and his chest ballooned out into two plump GG-size breasts. Sonic began to moan louder and louder, still completely unaware of his transformation. His figure became more slender, his hips got wider, his nose shrunk, his eyelashes grew out, as did his quills, which drooped down to his shoulders. His fur tone changed from a dark cobalt to a much lighter shade of blue, and finally, his penis shrunk and was replaced with a vagina. By now, Sonic was screaming in ecstasy, rubbing his, or rather, her, dainty hands over her newfound feminine body, and as the process completed, Sonic shuddered and orgasmed, spilling cum out her pussy and consequentially jolting herself awake.
Sonic blinked groggily, and sat up from the couch, much too sleepy to notice the wetness in her crotch, or her incredible new body. She slowly walked to the bathroom, and that's when she noticed that she felt heavier than usual. She looked down at herself, and the shock of what she saw woke her up immediately. "I TURNED INTO A GIRL!" she screamed, before realizing in horror that even her voice had become much higher than before. She ran to the closest mirror and examined herself, praying that this whole ordeal had just been one very strange dream, but to no avail.
Then, a deviant thought entered her mind. What if..., she thought, her cheeks blushing bright red. What if, I played with myself... Sonic shuddered at the thought, and yet at the same time, she started fondling her left breast with her hand. She let out a low moan, remembering that with size comes sensitivity. She worked her right hand down to her vagina, which was already wet with her feminine juices, swallowed hard, and fingered herself. She started to moan even louder, and beads of sweat began to roll down her hot, naked body, which just turned Sonic on more. Oh..ungh, this is amazing...Ah... Sonic managed to say, as she masturbated faster and faster, losing herself in the moment. In fact, she was so into her own pleasure, that she didn't even notice the bathroom door slowly creak open...
Who was it who opened the door?
