You found the perfect costume, a lumberjack. It had the typical red checkered work shirt, a pair of dirty faded blue levi jeans, a ripped split at the back, thick black suspenders, a dark grey beenie, and huge size 14 brown work boots. The costume even had padded muscles, a big round stuffed beer belly, and even a fake ginger beard. It also came with brown leather work gloves, and a large axe.
You grabbed the costume and raced back to the shit covered changing room, a small river of crap oozing from it. You went inside and stripped off, before eagerly pulling on the costume. It felt too big at first, but then you began to transform. You grew taller, to a towering 6"3, as the costumes padding became your own big beefy body, with huge shoulders, powerful and brawny arms, meaty chest, thick thighs and ass, and of course, your big round beer gut. You looked in th mirror, your face now that of someone in their early 40s, your bushy copper red beard, as well as your thick hairy forearms.
You grinned at your big daddy lumberjack body, before feeling your big belly rumble. Leaning against the mirror, you let out a loud wet fart, followed by a huge load of shirt, your asshole squeezing it out the back of your jeans, making it slop down your legs and the back of your jeans. You grinned at the smell of your first lumberjack shit, ripe from a diet of red meat and coffee, and above all, warm steaming scat. You put a boot up on the bench next to you, resting your axe on your shoulder. You then placed your other hand up to your ass, and with another grunt, pushed out another slimey, warm, potato sized turd. You then gave it a good old sniff, before biting into it, the turd slopping down into your beard.
"Mmmm... that's good"
You took a few more bites before smearing the rest down your shirt.
You then felt your stomach gurgle again. Leaning on your axe in front of you, you squatted down and pushed, grunting as you did. An avalanche of goopy lumpy shit poured out from underneath you, piling up. You gave a relived sigh, before hearing a noise outside.
"Omy what the fuck.... argh...no!"
It was a young man, about 20, horrified at the smell.
