This happens when you try the lonely fountain and miss your mouth, accidentally cumming in your eye. So you run to the sink to wash it out, while still cumming with your dick swinging from side to side like a sprinkler, all the while moaning with pain.
Now I know why girls get so pissed when you cum in their eye. It hurts like hell. I was giving myself a lonely fountain, came in my eye instead, then sprained my toe running to the bathroom to wash it out, pulling a moaning sprinkler all the way there.
