Sonic has two homes, his main home where he and his Concubines live in and a summer home.
His Concubines really like the summer home but Sonic isn't to keen because of the pool, but when his Concubines want to visit their, they have their many ways of getting what they want, and Sonic has little to no reasons to not give them what they want~
(This is one of my favorite pieces, this has been up on my patreon since last year finally posting it since I'm bursting with concubine au.)
