Art of girls voiding the warranties of vacuum cleaners (掃除機コキ). I included May's sprite too (#5).

In the case of variations, I prioritized versions featuring ejaculation, since I believe that many people appreciate the sakusei aspect of this fetish, and without guro, since I believe it would be a distraction.

Pay attention to the filenames if you want to know the sources. In the case of several of doskoinpo's pictures, I also mentioned the anime that a character is from in the filename.

Fair warning: a number of these pictures are from visual novels or short stories. If you want to fully appreciate them, you should check out the work they're from. (None of them are translated, though.) Links to associated short stories:

In the case of doskoinpo's pictures with overlaid text, you can probably find English-translated versions at either /g/1061637/ba10db3dc5/ (for Sakusei no Kiso; see #35-38 and #159-164) or /g/1225756/2f92d8c958/ .
