The ol' Sword in the Stone

Whilst recieving a handjob, the girl grabs the cock skin really hard and yanks upwards forcefully every few seconds, like is the guy trying to pull the sword from the stone in Excalibur.

oh nancy gave me the ol' sword in the stone last night.
I kept moaning in agony but she thought it was pleasure
so she kept pullinh harder and harder
now my cock looks like a slinky
