Moira Weir would approve. Original post here, although if you go there you will be greeted with a stern message that the image “has been removed for violating one or more of Tumblr’s Community Guidelines,” which is evidence that the pornocalypse is coming for Tumblr, a large part of the reason why these images are moving over here in the first place.

Bonus Image Provenance: I commissioned Bacchus at ErosBlog to research this image further, and he has come up with the following additional details.

This image has “Pinky” for a visible artist’s signature in the lower left. A bit of searching turned up this small gallery of Pinky artwork on ImageFap:

Pinky has a profile on Hentai Foundry with a total of nine artworks shared there:

Your image is titled simply “Tentacles”:

A slightly larger version (532×800, probably just resized upward given the lower resolution at Hentai Foundry) can be found here:

This search was an extra-easy one because I thought I recognized the artwork as the style of Azpiri, whose work used to appear in Penthouse Comix and Heavy Metal in the early 1990s. Sure enough, it’s from “Book 3” of a series called Bethlehem Steele, which can be found (along with links to much other Azpiri art) in this high-quality web gallery:

It’s unclear to me whether the Bethlehem Steele “books” were ever printed anywhere but in Penthouse Comix. A commenter at Bondage Blog says no:

Wikipedia’s article on Azpiri seems to support that:

Here’s a page with very-nicely-constructed galleries of many Azpiri titles, but unlike the Heavy Metal titles (which have official-looking covers) the “title pages” of the Bethlehem Steele stories appear to have been constructed (complete with headlines in the otherwise-implausible Comic Sans font) by the prolific and notorious comic scanner “Regdul”:

It’s possible I’m wrong, but I think fan scans like these (or back issues of Penthouse Comix) would be the only place to obtain printed copies of the work.

Here’s another link with a bit of information about the artist:

Your particular image was also featured on what looks like a promotional card for a line of Penthouse comix trading cards (and presumably, also appeared as such a trading card):

The caption there says: “SWEET TORTURE: Caught touching herself by the all-seeing eye of the Majestrix’s computer Info-Link, Beth is instantly held for punishment by the unfeeling machine. Her mind and body open before the rough intrusion of the cyber probes…”
