Recommendations of stories with casual lewdity/sex

Bit of a specific request, but I’m looking for stories that have elements of casual nudity as well as sexual activity and dialogue; e.g., two characters fucking while having a conversation about work, or 69ing in a semi-public area with others either passing by, watching with casual interest, or getting up to their own NSFW activities. Not to say that the characters aren’t into the sex or nudity, but that it’s so normalized that it’s not that big of a deal, if that makes sense.

Bonus points if it’s incest and/or group sex themed.
