...Sadly, it's just your typical wish-fulfillment threesome Touhou lemon fanfic, except the girls are "bodied yukkuri". You know, to keep it different. I ain't giving you the blow-by-blow account; it's just paragraphs of raunchy sex, sex, and more sex.
It's an awesome way to start the new year, I admit. Oniisan anon is a genius.
