Jon opened his arms wide and moved toward Karyn. "How about a hug? To celebrate being friends 'n' all" said Jon.
A little confused, Karyn accepted the hug. But as they were hugging, Karyn felt Jon reach into the front of her pants and press something against her crotch.
Shoving him back, she placed her hands on her hips.
"What the hell are you doing!?" she yelled.
Jon was trying hard to keep a straight face, he glanced at Karyn's crotch, which now had a clear bulge where he'd placed a penis.
Feeling her pants tighten, she looked down. Seeing the bulge, her jaw dropped, "EW! JON! Why would you do that?"
Jon burst out laughing, "Just a little prank to get back at you for the boobs", he smiled, smugly.
"Okay smart guy, want to play a little game?" smirked Karyn.
"Sure, why not?" replied Jon.

"We take it in turns to change or add something to the other person" she explained. "The loser is whoever wants to stop first."
"Whoa, you're on. There's no way I'm losing this." grinned Jon.
"Okay, take your clothes off, except your underwear, then meet me by the drawer."
