Thrusting your shaft into the bung hole of another creature such as a man, woman or a horse. Unlike the vagina, the bung hole does not self lubricate when one is horny and ready for action so many people choose a artificial form of lubrication such as K-Y jelly, butter, soap, olive oil, spit or diarhea. one may also violently shove his man rod into the bung hole without using lube thus creating a better challenge and some blood.
