Rough translation of the Pixiv comic uploaded at https://e-hentai.org/g/961664/88418f05e2/ or at http://www.pixiv.net/member_illust.php?mode=medium&illust_id=55477619. This is a rough work, so let me know if there are any comments or suggestions!
If you look at the rest of the series, the two girls that got the table work at a lab that produces all sorts of tentacle-based products. I assume this was something they grabbed from the lab.
