Aisuru Tsuma no Netorase Hōkoku: Gyaru Tsuma Ria no Baai

Aisuru Tsuma no Netorase Hōkoku: Gyaru Tsuma Ria no Baai is a Japanese erotic visual novel themed around netorase (consensual cuckolding).

The player is Masato Shirakami, a man who has been happily married to his wife Ria, a former gal (gyaru)-type girl, since shortly after they met during their college days. Despite the fact that they are happily married, Masato has begun to wonder whether there is another man out there who could satisfy his wife more, causing him to develop a cuckold fetish. When he tells his wife about his feelings, she agrees to cheat on him with his permission if that is what he really wants — a point after which there is no turning back.
