Perhaps cum comes from scum, since for some people, drying cum smells like fish or seawater? And since scumbag refers to a type of cloth strainer, perhaps cum referred to the smell of ejaculate in unwashed clothes, aka cumstains.
Love to be crossdressed in your sexy clothes and join the fun
It's just great that girls like this exist. It makes the world a better happier place. Well done. Nice chubby bodies. The girl at the back should have posed more than dance. Showing off that chubby butt.
