Double Handing 

1. When your penis is so big you have to jack off with both hands.

2. When you jack off with both hands to simulate the feeling of a vagina.

Two-Handing 

The act of grabbing a woman's head with two hands to pull her mouth over your penis as you cum to force her to swallow your semen.

She said she wasn't into swallowing, but when I was ready I interlocked my fingers and gave her a two-handing she won't soon forget.
