Have you tried reading Akatsuki Myuuto's "Isekai Harem Paradise" story? Actually, all Kyuuto story is pure harem, so read them all.So basically, big D means everything, big D is god, big D is life.
I guess he would go on a pilgrimage to spread hisseedsblessing then.
If that isn't the best part of this chapter, I dunno what is.
