My story is rather boring. Nothing really profound happened, but here, read if you wish.
When I was a little girl, I had this amazingly soft blanket. It was so soft, so furry, so wonderful and warm to hold, and I loved it.
On winter nights, when it was coldest, I would warm the blanket with a hair dryer, and then wrap it around my small body, with enough in front of me to pull close to my body and hug it.
I imagined that the soft blanket was a big bear, or a fox, or even a dog or cat hugging me and humping me with warm, tender love.
I would rub the soft fur over my soft nipples until they became hard and tender, and rub the blanket against my holes as well, letting the tickles build more and more, until I'd start giggling and feeling very aroused. I remember uncontrollably smiling from the nice feelings.
This is a bit weird, but when the feelings got most intense, my nipples would puff out and I'd start shivering and trembling, and then I'd make little "yiff" and "nyaa" noises. I'd always end up peeing myself. I usually learned to pee first, in a toilet, but no matter what, the feelings always made me completely lose control of my bladder, so I'd end up making at least a little dribble mess on myself.
I'd pee myself and get the blanket wet, but as you can guess, that only made me feel dirty and blush as I went harder. At that point I'd just spend a few minutes having shuddering orgasms, until I became exhausted and fell asleep.
Boring story, but those thoughts of snuggling my furry blanket as an animal companion stuck with me and continue to feel comforting, plus I like the idea of applying animal traits to humans.
Hugging a fursuit is the greatest thing ever.
