Kind of funny but the watersports are a bit much. Is there anything stopping him from sending his house back to Earth? Well he would lose his tsukumogami then.
Another perverted isekai, huh? Damn author, please at least make some justification for them to do the pervy stuff just like the one in Shinju no Nectar, that pissing scene here add nothing to the story.
But at least from the spoiler comments in here I heard they did the pervy stuff to renovate the house in the future, that's ridiculous enough to keep me interested to this silly manga, followed!
