Originally from a LiveJournal called Retro-Futurism, sourced on tumblr to Am I as much being seen? via spacebitches.

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

The source information in the tumblr stream leads back to this “Retro-Futurism” Russian-language LiveJournal, which is I think relevant to your interests:

(See, e.g., Sigourney Weaver in space helmet and panties, or this Sputnik stripper)

The specific source post for your image is here:

The comments on that post source the image to Carlos Valenzuela (*Valzonline) on DeviantArt, where the image is titled “Cosmic Thrills”:

Valenzuela seems to do a lot of fictitious retro movie posters and pulp magazine covers:

Bacchus is actively taking image research commissions, and if you have adult imagery you’re curious to learn more about, I encourage you to visit Bacchus’s introductory post for his image-searching service, where you can find details about how to commission him.
