The sounds on this animation are "crushed" enough to really give this coitus a nice, retro feel that compliments the sprite work. You can practically see the health bars and experience gain.
As an unintended consequence, the consistency of most of the details does make the classic record scratch sound effect sound out of place.
Still, the artwork and animation do give off pleasant, old-time vibes that you don't see captured like this in NSFW animations. I appreciate the detail put into it.
