F4U is probably my favourite Hentai artist as yet discovered, more than anything because of the shameless atmosphere and primal animalistic intensity in his/her stories. People give in to their primitive lusts and lose themselves in relatable, believable and interesting ways. It's as much a delve into human psychology, sexuality and sexual behaviour as it is fap material, and it works brilliantly on both counts. I'm honestly glad Fakku let's me financially support such things.
