Similar to that of a regular handjob, the differnce being that the person giving the handjob uses a slide hammer motion. Starting slow at the tip and then stroking down with extreme force until being stopped by pubic bone. This takes place repeatedly until the person receiving either passes out from pain or a bloody ejactulate occurs. Hopefully both. Slavic in orgin.
You guys hear about Kurt? He spent all day in the ER cause his Slavic girlfriend gave him a wopper of a Slide Hammer Hand Job. He won't be riding his bike for a while.
