Later in the story it focuses on actual plot though and becomes fun.
Even from the start there's some good plot points, and sometimes it tricks you and pretends to be a wholesome (it's not!) survival adventure, but then also the guy is carnal with a house and the author is obsessed with cute girls peeing so that either counts as comedy or cringe depending on your perspective. It's not the right kind of horny if you're just looking for smut though, it's more like a story with occasional horny breaks most readers couldn't overlook. It's amusing if you do skip over the horny scenes though.
