After another failed attempt at trying to steal the Master Emerald, Rouge was gliding across Angel Island as fast as she could, with Sonic, Tails, and Knuckles right behind her. She needed to find a hiding spot, and fast! She skimmed the ground for a good place to hide, until she saw a cave that led underneath the surface of Angel Island. Without the others seeing her, she swooped into the cave, where she hid while the others tried to figure out where she went. As soon as they gave up and left, Rouge started to crawl slowly out of the cave, but then a bright red glow coming from deeper within the cave caught her eye. For some reason, she felt as though she needed to go see what it was, hoping that it was some sort of priceless jewel.
But instead, she came across some sort of red rock. It did glow bright red, but looking at it closely, as she picked it up, it was just a round, lumpy piece of stone. Normally, she would have chucked something like this in the garbage and go home, but something about this stone made her feel all warm and tingly inside, somehow wanting to pleasure herself. That feeling became stronger, as she looked around herself, and noticed that she is now about 10 feet tall.
Rouge was surprised by this, yet also really enjoyed it. The feeling inside her grew to the point where Rouge was starting to feel horny, as she felt her hand slowly run down her sexy body, and grab her own ass. She got to the point where she wanted to start pleasuring herself, but she thought whether or not here would be a good place to do it.
Does she go somewhere else, maybe somewhere more private, to pleasure herself, or does she start doing it right there in the cave? Or maybe she wanted someone else to pleasure her, like Shadow, or Knuckles.
