When I left the bathroom Greg was gone, and the book was sitting where I left it. I felt a thrill of relief — in my hurry to get changed, I hadn't even considered that Greg might run off with it. I grabbed the book, flipped it open, and willed it to show me the page where I'd left off. Time to turn things back to normal. As the book went through the usual routine of scrawling the words out across its pages, I frowned. The paper was already dry. Surely it hadn't been long enough for that, even in the summer heat...?
Below me, the page finished writing itself, and I noticed something was odd. Where the text was usually written in a slightly faded black ink, most of the words on this page now showed up in an odd shade of gray. Looking closer, I could swear the ink was almost shimmering. I leaned forward, and frowned. I was right — most of the ink on the page was glazed over with a shifting, glimmering coat of white, making the words below look like silver. An even closer look and the white accents started to seem familiar.
"What the fuck did he do..." I muttered, staring at the cum-laced ink which now made up over half the words on the page.
I turned and grabbed the nearest pen. Maybe it was fine. Maybe the book was just...I dunno, hungry or something. Can book get hungry? I shuddered, remembering how I'd tasted the same cum only minutes before.
Carefully, I reached down and tried to cross out one of the words on the page. For a moment, everything seemed normal. I held my breath, waiting for the words I'd crossed out to fade away like usual, but, instead, it was my own ink that disappeared.
Fuck. The changes were permanent.
