エルフのかわい子ちゃんPatootieはあなたのヘッドフォンを返しません - 男性のためのエロティックなオーディオ

It's been 6 months since You (The Listener) died and got reincarnated to another world. You were given extremely overpowered magic powers and you got to bring your old Walkman to your new world. Since then, you befriended a High Elf Princess (The Speaker) and entrusted her with your Isekai secret. As of late, she's been taking your Walkman without your permission and, while you're glad she likes your tunes, it's really starting to piss you off. Hopefully she'll be reasonable and give it back and no sexual shenanigans happens. Just kidding, that's exactly what happens.
