I only saw one of these posted when I searched Disgaea in this thread, so I figured it might be worth mentioning the others that I'm aware of.
In Disgaea 3, the Dragon unit has an attack called "Inside Tour" that's a full tour. It knocks an opponent in the air with it's head, suctions them up with a visual bulge in it's throat, then turns around, strains for a bit, and poops them back out with a pink poop effect on them.

It pulls a target in it's mouth, chews on them for a bit, then spits them back out from the mouth on it's back. The other one is "Hyper Suction". It sucks up 5 targets and some debris and then shoots them out from it's back mouth in a giant tornado-like air stream.

Zeroken jumps in the air and launches himself back down at the opponent while trying to do a flying kick. He misses his target and accidentally goes into the mouth of Ursalia's Prinny. She starts hitting her Prinny on the head and it eventually spits him back out at the opponent.

The snake will fly down and latch on to several opponents, chewing them up as they kick and struggle. The opponents will slowly pulled in while they kick, and eventually be swallowed whole. Afterwards, a bulge will go up the snakes body and into the cockatrice, who then spits out eggs that have the opponents inside of them.
Honestly, I think this is one of the best vore scenes I've seen in a long time. I'll try to record it tonight after work and post it on my youtube for anyone interested in seeing it.

Here's the video to the Disgaea 4 vore involving several characters.
And some of the moves you can also combo with any kind of ally skills that are close range to the target so they'll be eaten as well (but won't be damaged by it). For instance; you can take a close range attack like Mao's "Blast Finger" (basically his hand starts glowing, he leaps at his target, grabs them by the head, and then point blank detonates from his hand) and combo it with the Dragon's "Inside Tour" - so Mao will grab is opponent, but before he does the explosion part, the animation will switch over to the Dragon's move and then he'll be able to finish the rest of his animation after the Dragon's animations ends.
