A device used in hentai games and anime to avoid showing a man's penis, thus circumventing Japan's censorship laws. Usually the penis is shown as transparent cylinder or as a beam of light.
This chained-up underage anime schoolgirl who may have been my sister was sucking my invisicock so hard I had to activate my tentacles before my orgasmeter was maximized. I'm sure glad real life doesn't resemble hentai games at all in any way.
