That's pretty easy. It's not really a fan servicey show at all. Yeah Nagi has gigantic fucking honkers, but the show never goes out of it's way to turn that into active appeal. She's always dressed in a modest button up + jeans and any time camera angles focusing on her body are used, it's because she's doing something that necessitates that angle to show the viewer what she's doing. You never see opportunistic choices made, like having her get wet transparent clothes in the river episode, or the camera focusing on her ass/tits when she's standing around doing nothing. At the very most you could say that choosing to give her a fertility sex goddess body in the first place is fan-service, which can be argued against since it's hard to call something fan-service purely for the crime of existing. Overall, I wouldn't worry about my mom walking in on me watching this show.
