Actually I was searching about the tentacles scene and found out it is in LN Volume 8 Life 2. Though, the anime upped the ecchiness quite alot like there wasnt any sucking the nipples part but they added it.

About the foot massage, I also searched but I can't find it. Are you sure it is in the novel and it wasn't anime exclusive?
