勇者籠絡プロジェクト ~心を蕩かす魔女のキス~ (Google Translated to: Brave Cage Project - A Witches Kiss that Fulfills Your Heart ~)
https://www.dlsite.com/maniax/announce/=/product_id/RJ245694.html
Audios of a witch kissing you, the hero. With a drain/control/etc kisses. In many places with surround sound audio.
If it's anything like their other works, it will feature CGs for you to enjoy to for many of the chapters.
As of right now, patiently waiting because I swear that says it should be out right now of this post! (Plus having to wait for it to show up on the Eng. version)
There's a demo audio to listen to but the actual product usually has a bunch of long ass audio tracks, generally with and without audio tracks and choice of .wav or .mp3
