|1.||Russian Meat Grinder|
Same as the Russian dentist but the girl has braces..
When receiving a blowjob, you cum in the girls mouth. She doesn't spit or swallow, but she proceeds to use your dick to brush her teeth with your newly deposited cum. But she has braces.
You: Dude my girl was gonna do the Russian dentist but she just got braces on. Ouch!
Friend: Yeah thats what we call the Russian Meat Grinder
