shitty carwash

A shitty carwash is when you cum on a someone's face, then use your dick as a windshield wiper. Alternatively, you can use your hand in a back and forth action. You can also add carwash sound effects as you see fit.

I gave her such a shitty carwash last night, she couldn't see for 10 minutes.

OMG. I think he gave me a shitty carwash. He came on my face then kept rubbing his hand across my face making this awful squeaking noise.
