Google only gave me 'mothers daughters and son' but that didnt come up in e-hentai.

If you were looking on e-hentai, it would not have shown up since it has shota material. Here's the link, none the less:
https://exhentai.org/g/806595/ebf08fcfb4/ - [Hatomame] Uchi no Oyako to Otokonoko! Oneesan-tachi no Seiyoku Shori ni Tsukawareru Boku | Mothers, Daughters, and a Boy!
Also, for reference, the artist is Ago.
