The bookshelf

Turning quickly, you head directly for the bookshelf, barely looking it over before grabbing one of the books from its top shelf- specifically a large, leather-bound volume. The shelf collapses when the larger book leaves it, falling into a pile of dust on the ground.

The thick leather volume has no discernible markings on the front- no title, author, or any other distinguishing remarks. When you open the book, it seems like it's not even in English- each page is in a set with the one across from it, one page with two pictures and the other with strange lettering, words that you don't understand. The first few pages are rather mundane- the first depicts a woman twice, the only difference being her hair color. On the second is a pair of men, with one appearing to be slightly taller.

After a few more pages, you turn an additional page and gasp. A woman is drawn, twice, fully naked, with the picture on the left featuring a larger pair of breasts. The next page is similar, except with a naked man, his penis larger on the left. On the next two pages are the same, except reversed, with the "larger" person on the right. Another page displays a woman lactating, and another shows a man ejaculating. Later in the book come even stranger pages- pictures on the left start to feature animal parts, from hooves to frog flippers, cat tails, and even one page with a very detailed drawing of a horsecock. There's even a woman with what looks like squid tentacles extending from her back. On the final page, there's only one image- a large pentagram, with a humanoid form extending out of it.

Each of these pictures seem to correspond to a single sentence, and it's likely that you could attempt to phrase them, though the words look absolutely nothing like English. After a quick look over, however, you decide it's not worthwhile to you- naturally, you recognize it as some sort of magic tome, likely one that changes the body of the user. It'd certainly fetch a hefty price in some of the auction houses, however, so you slide it into your carrying bag before turning back to the room behind you.
