Dave took the medallion from Luke, plucking it from the bag with a smile. As Luke opened up his mouth to protest David silenced him with another quick kiss. "My turn. Trust me. We can have all sorts of weird fun with this." Luke just sighed and stretched out on the bed to watch.
Placing the medallion over his head, Dave only grimaced slightly at the cool metal against his chest. With a flourish he grabbed one of Luke's hats off a hook on the wall.
"Wait!" Luke said, hand out, but it was already landing on Dave's head.
"That's not my hat.." Luke said with a wince as Dave stared at him. "It's Lyle's. Mom must have thought it was mine and put it in here."
Instead of looking upset, Dave smiled. Friends with Luke for years, he knew Lyle well enough, Luke's older brother was a complete jock. And as he felt his body start to stretch out, he felt a twinge of excitement. He had always had a little bit of a thing for Lyle since he figured out he was bi.
Luke could only stare on as his friend suddenly shot up five inches, his lean body suddenly packing on some solid muscle. Naked as Dave was, Lyle got a show of everything, from the swelling of his chest to the tightening of his abs, even watching closely as his arms and legs thickened and gained more definition. Luke found himself getting hard at the sight. Dave was getting aroused as well, even as his cock shifted around, losing some of its girth but growing longer. It was almost twin to Luke's original dick, almost, Lyle had a heftier set of balls.
Dave's skin tone began to lighten to Lyle's paler complexion, before tanning slightly. Though tan lines showed in places revealing his naturally paler skin. The hair on his head and body both turned blond, some shaggy locks slipping free of the hat as his hair grew a couple inches longer on top, the sides still shaved down, sideburns growing in down in front of his ears. More hair grew in on his legs and arms, as a light dusting sprouted on his chest and in a line between his six pack. The changes finished with his facial features, Dave's face slowly morphing into Lyle's boy next door good looks that got him all the girls, finishing as his eyes swirled from brown to green.
Dave reached down and hefted his cock in his hand, looking to Luke with a smile. "Like what you see?" He teased, noticing Luke sporting his own arousal.
"Dude, that's my brother." Luke said as he sat up, trying to shield himself a little.
"Considering you're me.. well, normal me. No, I'm not your brother." He took off the medallion and set it on top of Luke's dresser so as not to activate it again, pulling his hat off and dropping it on top, then stepped in closer. Dave looked down at Luke in his old body with a cocky grin, he was so much bigger now. He was sure he had this fantasy before from the other side, and knew just what to do. Leaning over, he kissed Luke a bit forcefully, then broke it by shoving him back on the bed. "I hope you're ready for round two."
