living condom

A situation in which a live creature is used as a "sentient condom", "cock sleeve", etc. The creature in question does not necessarily have to perform the implied function of a condom (e.g. contraception) but only has to serve as a covering for the penis in question. Instances where sex does occur may be anal_vore or unbirthing.

This can also refer to the inanimate object condom being given anthropomorphic qualities to make it "alive".
