The act of oral sex given to a man while the woman uses both her hands at the same time to grip the shaft and simultaneously stroke and twist as she sucks.

A man of adequate penis length and a woman of excellent skill is needed to pull off the dually.
The wife was too tired to fuck last night but she gave me a wicked dually.

I brought home flowers for the old lady and got a dually in return.

Woke up this morning and caught a dually before work.
