My balls have never gotten sore, I don't know what's wrong with you guys.
Push your dick against the side of your leg with your thumb until you're ready to cum, then pull it out and jerk it to finish on the table. Simple. No ball pain, no exhausting arm movements, no fapping sound.
If you don't care about making a mess, don't pull it out. It's a satisfying orgasm when you haven't jerked at all and just cum from applying pressure; only downside is cum on your leg and pants/underwear.
I masturbate about once a day and only spend about 10 or 15 minutes a day now. I used to spend half the day masturbating sometimes, and I'd ejaculate maybe 3 or 4 times each day. I wish I had no sex drive at all, but my current masturbation habits are not very bothersome.
