an advanced blowjob technique applied to a penis of significant length. where two hands are placed at the base of the penis and rotated in opposite directions (as if working a peppermill) while deepthroating the penis so far invoking a gag reflex (thus creating a similar noise to that of a peppermill).
Cyndi's only option upon seeing James' long hard cock was to peppermill - knowing that's the only way she could please him thoroughly.
