Someone teach this artist how to draw balls..

uniballs? are y'all serious? balls usually tighten up like that when the person approaches orgasm, it's part of the mechanism of ejaculation.
of course there are people with 1 testicle (born with 1 or lost one after injury or cancer), but that's different as it's permanent unless they opt for a silicone or saline testicular implant. but that's not the context here.
Nice Snow White moment
