Porn Game: Succubus Heaven v2024-10-11 by Chaos Gate

It was a time when lewd demons began to emerge from among people.
The battle between the lewd demons and the demons',
demons has become increasingly fierce since a noxious gas eruption occurred in the center of the continent.
The "sanctuary," a relic from before the disaster, maintained a precarious balance,
but it was clear to all that the peace was fleeting.

In the midst of this, an anomaly in the sanctuary was confirmed at a ruin on the continent's frontier.
Three people were assigned to deal with the situation: the witch Eleonora, her follower Sera,
and another witch Dorothy.
There was no time to wait for further support.
The three of them had to go into the dungeon where the miasma was,
spreading to get the stopped sanctuary back in operation as soon as possible.​
