Much like the action of a sucker punch (where you unexpectedly punch someone in the gut), to sucker dick a person is to either penetrate and/or slap them with your dick whilst they least expect it.
1. Man, I totally sucker dick-ed Jane last night, she was not expecting it at all!

2. "Hey, so is sucker dicking like rape?"

" Nah, it's more like when you're cuddling in bed with your girlfriend and you put in while she doesn't

expect it. It's also when she's crouching or on her knees and you smack her with your dick."

"Oh. Sweet."

3. "And on his tombstone it shall be written, 'Here lies _________: Caring Father, Loving Husband, Sucker Dick Champion".

Can also be used as noun referring to someone's mouth and at the same time suggesting they suck dick with it. Used primarily to describe someone's mouth who talks too much, is too loud, or says something you don't like (relates more to speech than anything else). I've never heard it used in reference to eating.
I wish that loud bitch over there would shut her dick sucker already.

John: Eat shit and die asshole
Joe: Shut your dick sucker and throw down

Get away from me with that dick sucker -- said as a nappy ho tries to kiss you.

Biff: Eat shit and die asshole
