Firstly, notice the size, spacing, and delicate areolae of our heroine's breasts. To any connoisseur of the visual arts, it is clearly a visual allusion meant to invoke Titian's Venus Rising from the Sea.
One must also pay attention to the fact the hero's sturdy stallion is a completely different color from the rest of his body. This is a clear visual metaphor for his sexual uncertainty since he is virginal at this point and laying with our experienced heroine.
Of course, I would remiss if I failed to mention the exquisite soundtrack. The smooth jazz piano that plays throughout is clearly reminiscent of Thelonious Monk. It does not take a particularly keen ear to notice the clear similarity the composer wished to establish.
The voice acting gives us some truly inspired performances from the incredible actors at Media Blasters. Short of the Royal Shakespeare Company, I can't think of another acting troupe so ripe with talent.
The plot is unequivocally masterful. Sex Friend is the most tasteful artistic representation of eros I've witnessed since Tristan und Isolde.
At certain moments, I had to turn away from my computer screen! Surely this was too divine for such a base being as myself to witness! I can't believe that such miserable wretches as Masaaki Yuasa continue to make anime when works like Sex Friend exist! We are unworthy! We are unworthy!
