There are some guys out there that absolutely have a thing for fur coats and fur in general. The tactile sensation of the soft, warm fur gets them going the same way guys with a pantyhose fetish get a charge out of the nylon fabric and how it feels against their skin. No animals had to die in the making of a pair of pantyhose though. I’ve never had a guy into this fetish tell me fake fur was acceptable as an alternative to them. Maybe if it feels as good it might, no idea. Some are quite into stuffed animals even though they are decades beyond their childhood years. Some poor toys have been abused for decades or replaced with new ones.
Perhaps years ago the older, sexy aunt came for a visit wearing a beautiful mink stole and they were quite enchanted by it and how it felt and it might have made that first ever tingle in their pants. They associated it with the fur ever since. There’s no denying the softness and the sensual feel of fur, and many would enjoy how that feels on their dick. One caller is absolutely obsessed with satin and the cool silkiness of it. Some fabrics just send a guy into a sexual frenzy of lust and they want it in some capacity as they masturbate. It just enhances the entire experience for them.
If they couldn’t find sexual enjoyment without it, then that’s a bit of a crossing a line territory, but for a once in a while kink, if it’s not hurting anyone, why not. It’s their own private business. There’s plenty of thrift store finds of old stoles and wraps and even full coats. They just are not as in fashion today, so second hand ones are easier, and cheaper to come by to indulge their fetish for them.
