This story is about Issei and his quest to be a high level devil and become the harem king. That's what this story is about. It's not about vali. He is merely a rival to push Issei to greater heights in power. Not only that all people have dirty thoughts like that. Just many are better at hiding the thoughts. lol So unless the author wants to do a side story on a individual character, that won't happen. Plus there's nothing wrong with showing affection to someone you love. Just it gets more amplified in Issei case because he's a devil. Plus the female characters don't mind it at all and in many cases encouraged said actions by Issei. Hell if they didn't want the Issei to do what he does, they could easily put a stop to it.
