Netore no Yu 2 ~ I made my guests hold my wife at a hot spring inn ~ Yume Ayakawa - Ayakawa Dream

Meng, a young and beautiful wife, is taken to a hot spring inn by her husband. At the inn, they discover it's a shared hotel where other male guests are present. The husband seems to have planned this, and Meng is initially hesitant but eventually participates in a gangbang with the other men, while her husband watches or joins in. The central kink of this scene is the wife being shared among multiple men, which appears to be a form of cuckolding or gangbang scenario.
