*Knock* *Knock* *Knock*

"Oh no, Amy hide!" Sonic spoke hurriedly. Someone was at the door, and if he didn't answer soon, they might suspect something. Amy's head quickly darted left and right, before she finally rushed into a closet.
"Sonic?" he soon recognized the voice as Dulcy. What could she possibly want? And did it have to be right now?!
"Just a sec Dulcy." he said. Now with Amy hid, all Sonic had to do was calm himself, and act casual. At least all the tension had caused his boner to go down, so that was a step in the right direction. After taking some deep breaths, he made his way for the door.

Sonic was not going to enjoy lieing to a friend, especially someone as nice and honest as Dulcy, but no one else could find out. Even if he did let her in on the secret, that would only put her in danger of getting caught, and Sonic was not about to let Dulcy get in trouble just because he was horny. Maybe if she knew about what really happens in Knothole when the sun goes down, then it might be possible.

"Hey Dulcy what's up?" Sonic spoke very quickly and just briefly looked up at his friend before turning around to make sure the door closed all the way.
"Actually I needed to talk to you about something, sorry I had to drag you out here." she said.
"Oh that's okay, if you want I can try and get a bigger door bu-....." Sonic lost his train of thought once he turned around. Dulcy's giant shadow should have clued him in, but even it could not convey the massiveness of what Sonic now saw.

His jaw stayed firmly planted on the ground.
Dulcy had always been the biggest of the Freedom Fighters, and it wasn't just because she was a dragon, but Sonic had not expected this. From her legs up, Dulcy had gotten much more, curvy. Fatty hips, even bigger trunk like legs and arms, and an even more massive belly were all now part of Dulcy's already fat form.
What reallt caught Sonic off guard, was Dulcy's now substantial bust.
Substantial nothing, two firm, scaley double D's now made up her chest.

"My, my, my Sonic, I can see why the girls love you." as Dulcy giggled, Sonic quickly realized what Dulcy meant. Seems that oggling her blubbery form had brought him to a full mast. He quickly brought his hands down to try and hide his embarassing wood, but once he did, Dulcy 'encouraged' him not to.

"Oh Sonic, don't be ashamed. I am very flattered, and I was hoping you would have this kind of reaction. If it's not too early for you..." Dulcy's stopped and turned her back to Sonic. She shook and wiggled her collosal caboose for the hedgehog. Sonic tried to to look away, but couldn't. Just the sight of that buttocks was really getting him back in the mood. Each cheeks bounced and smacked loudly against each other, and each impact made them jiggle.

By this time, Amy Rose had come out of hiding. She couldn't stand waiting any longer. Any time she had to hide, all she could think about was somebody figuring Sonic out and taking him away from her. She quietly cracked the closet door open, and so no one. With nobody in sight, Amy quietly crept up to the window, just for a quick peek at who might be interrogating her boyfriend right now. What she saw though, was more shocking than scary.

"Oh my god....what is he doing?!" Amy thought. At first, what had caught her offguard was how much bigger Dulcy's already huge butt was. Just seeing each blubber ball of fat behind the dragon somehow get bigger was just stunning. However, Amy's mood soon went from shocked to angry when she saw that not only was Sonic staring at her, but was fully erect as well. Even if she and Sonic had had included others in their sexual games before, Sonic was hers alone. Not to mention that a display like this out in the open could blow there cover!
However, when Amy turned her attention back to Dulcy's ass, she found her rage being strangely quelled. At this point, Dulcy turned around and began shaking her boobies and belly for Sonic. Amy not only listened in to what they were saying now, but also grasped one of her breasts.

Dulcy didn't say a word, she just smiled as she silently seduced Sonic. She shook her jiggling jugs for him, loving the drool trickling down the hedgehog's mouth. Slowly he moved forward, and brought his hands to her body. Dulcy really smiled once his hands found her large belly, the source of corpulent, bouncy body.
Unfortunately for her, Sonic finally asked that question.

"Dulcy, how....how did you get so...big?" she immediately froze up once he asked that. In the midst of seducing the sexy hero, she had forgotten the reason why she came to Sonic's in the first place. She cursed her conscieunce as juices dripped dow her legs.
Sonic didn't notice, until Dulcy removed his hands from her belly.

"Well actually, that's what I came to talk to you about. I wanted you to hear it from me first." Dulcy litely tapped her tummy. As Sonic looked at her with waiting eyes, she decided to tell him the truth. She said "All this fat, it used to be Sally.".

"WHAT?!!!!" Sonic responded.

"WHAT?!!" Amy did the same.

Everyone froze once they all realized that after hearing that news, Amy had impulsively opened the door. Dulcy was stunned at first, but soon her perverse grin returned.
