Can u get something that keeps your mouth on a cock? Some type of restraint?

I've made a tie with rope before that did the job.😊

Do you mean a cock-shaped gag, or a harness that keeps a mouth at a cock? Pretty sure both exist.

Bungee cord so there is just enough movement for a few inches, but not enough to get past the tip

Yes there are a couple different options such as ring gags. Or tying them down so they can't move their head away from like, a dildo stuck to the wall.

Tape?

Depending on what you're going for there are also penis gags.

A ring gag to start for sure. Then it would depend on the situation. If youre on a chair and have your sub infront of you facing the seat, you can attach your subs arms to the legs of the chair. The back legs. That will keep their head low enough to not entierly be able to get away. From experiance this has also worked cuffing a sub to the arms of the chair. That did provide more room than cuffing behind the chair's back or the back legs. 

Leash and a ring gag works as well with a little more effort on the doms end.

They also have cock shaped gags in various sizes as well.

There is a spider gag, gag that can be inflated, cock shape gags

Simple enough to use a large belt and have it go around the waist and behind the head of the giver.
