Overgrip - Zamius, Mazjojo
I think it's hot! The boys got fuck real hard inside out, every orifices was filled and thoroughly violated by a gigantic pervy octopus. *jumping with glee*

... finally a tentacles sex manga that almost has all the required sexual tentacles actions I ever wished for in this genre.

I am glad I found this and gets to add it here on GR for all my friends!
