I think the reason of misunderstanding is cause of this line in the description *he gets excited at the prospect of his almost 30-year-old self doing it with a high schooler* cause that sounds really weird.
But actually what he said in the manga is for him to have a great sex life even in highschool
But after all it's a dream so like yeah
damn that was such a tease I really thought we would be having a tentacle chapter *sighs*
