"You're crazy!"
"Why? You tellin me' YOU never wanted a tail?" Grinning, he pulls himself upright, flexing and swishing his newgrown appendage. "Come off it. There ain't a guy here who hasn't thought about it at one time or another... wondered what it be like to put one through his pants..." Still grinning, he looks back at his butt. "Well I tell you, dude - it's totally freakin' HOT!"
To your amazement you notice he's now displaying another large bulge - this time up front!
"Yeah, I can see," you mutter through gritted teeth. It's so damn hard keeping your own tail from growing.
"Sexy to feel, an' sexy to watch..." he grins, walking in a circle around you. You want to turn with him as he moves, but you daren't move a muscle. "I guess that's why they don't show anyone sproutin' a tail in movies and such. It's too hot for audiences to handle."
"Maybe it's just too tricky to film," you counter.
"What, with special effects these days? If a guy can grow a muzzle in werewolf films, he can certainly grow a tail. Naw, they can do it - they just daren't show it. It's too much of a turn-on... The censors would have a canary!"
For a moment he's silent. The air is warm and still. But you know what he's doing - you can sense it without seeing it... This stocky young guy is staring at your butt!
