I get so excited to see others load their pants with long poop so when I can have that kind of a bowel movement I get hard fast.
I do too! They were more common for me when I was younger, but occasionally I get them and really, really enjoy them. I once had a load so big I waddled like a two year-old. I was so hard, I came in my pants without touching myself.
Like everyone else said, a very firm turd. Mine are usually just slightly too soft and they end up just blobbing up.
The tightness and resistance in your undies is also a tradeoff. Not enough resistance and the turd will just plop out, too much resistance and a turd that should tent will squish a blob up. For me it’s best to wear underwear that are one size too small. The tenting looks HOT in compression shorts and lycra.
