When a guy pulls out his penis and grabs gently with both hands (index finger and thumb) his
foreskin.
He pulls up the
foreskin (toward the sky) and stretches it slightly, so his
foreskin has the form and attributes of a shot glass.
A second person fills up the foreskin shot glass with hard liquor!
Now “a” person goes on their knees and receives a cockiy.
A shot directly into the mouth out of a foreskin shot glass.
