Finger Jack 

When a man bends over and masterbates fastly while someone else fingers him with 2 fingers from behind and rubs his testicles.

Sarah: "I'm so embarrassed! I walked in on my parents doing the finger jack."

Mark: "That really sucks.."

Finger jack from the back

The act of finger penetration to either the vagina or anus, while from behind. This can be accomplished standing, sitting, bent-over, or preferably while she's asleep with her back to you.

While my girl is blowing me in my lap, I like to finger jack from the back to pass the time. Then I cram my fingers up both of her nostrils so that she can smell her dirty ass all day long.

Fingerjack 

Jack ones finger into the vagina or anus of a female counterpart. Hopefully while she is drunk or passed out.

I took home a nasty skank from Casey's Bar last night, and proceeded to fingerjack the drunk bitch while she slept in the passenger seat.
