Adam looked to pleased to be suspicious, though he had no need to be. "I'm glad we can be friends" He said, mentally listing off everything he wanted. "How about we settle for something different for now. I want to be big. Really big. I want lots of muscles and a really big dick, and..." belatedly getting self-conscious, he let the sentance die.
"I know what you mean, Adam. Typical male." Circe didn't sound angry, though. Maybe amused. "Times have changed, but some things don't. Of course, you want it to be as if you've always been that size, and so on. Alright. You will have your respect." She didn't make any special gestures or mutter any incantations that Adam know of, but he felt a very tingly sensation in his stomach...
His whole body quickly inflated; he got taller, and taller. Stopping around 6ft 3, Adam's muscles quickly followed. He looked on in wonder as his massive feet became hidden thanks to his heaving pecs. His shoulders grew enough to make his already massive arms stick out further, though this was offset by the fact that he had to stand with his legs apart due to his 34" quads and the raging 14" cock which felt like it was going to explode in any moment.
It goes without saying that he got hairier as well - the stuff grew on his face, his chest and most places spare his back, thick and dark like his hair.

"Hey, wake up already!"
Adam grunted at the sound of his sister's voice. "Yeah..." He grunted, his deep new voice taking him by suprise. Then he remembered what had just happened, and he sat up abruptly. Circe, sat at the end of his bed, was knitting a small jumper which would fit a five year old.
"You're awake, I see. Do you remember anything?"
"Last night..." Muttered Adam. "I hope you didn't get embaressed..."
Circe gave a very unmythical shrug. "I've seen lots of men get off on themselves. Hercules was pretty bad for it. Of course, you're about his size now actually."
"Oh." Adam replied, a huge hand cupping one of his pecs. Circe must have cleaned the room, because he'd spent the night getting off at his own reflection. Now the room actually smelled clean.
"Adam, I know it's a Saturday but it's nearly lunchtime already!" Rebecca squealed. "Come on downstairs! But make sure you're actually dressed!"
Adam grunted and roled out of bed, landing with a very decided thud. Going over to his wardrobe, he pulled out a wifebeater which looked made for someone 50lbs lighter than him, and some boxers which he would have worn before Circe made him look so great. Tugging both items of clothing on with some trouble, Adam realised he wasn't hungry. He just wanted sex, and lots of it.
"Adam, you could at least go and eat something." circe said, more like a babysitter than anything. "You can appreciate yourself later."
"This isn't enough. You can make me bigger, right? Right?" Adam asked, turned to Circe and not caring that his cock had tugged right out of his boxers and was leaking on his vest. "I know you can."
"I can..." Circe said with a smile.
