Hey Boden. I was a painting contractor for many years and we had something like what was mentioned already. Ours was called a painter's mitt. It is a mitt with a cloth liner and a 3/4" nap outer fur skin. You had to wear a rubber glove or the paint would get all over your hand as the paint would soak through the cloth liner. You might also try what is called a wienie (spelling?) roller. It's a roller that is only about an 1" thick that slips onto a 1/4" thick roller rod - thus name weiner, or weinie cause that's what it resembles.
I would suggest a 3" long (they have 6" and longer), 1/2" nap lambskin with a short - 6" or so - arm (the short arms are easier to control). The lambskin is important as it holds much more paint and doesn't 'spit' as you're rolling like a polyester or nylon roller skin. But be careful, it can hold a LOT of paint. You have to play with it to get used to its capacity.
After we were done, if we were using oil
based paint, we just threw the roller away as it would cost more in paint thinner to wash it that the roller was worth.
If you go with the mitt, make sure it's lambskin too for the same reasons as above.
