The mistress or side-dish in an affair. Usually associated with a cuckquean (a woman who is aroused by her male partner having sex with another woman or women).
John was out with his cuckcake while his cuckquean wife waited at home, playing with herself and waiting for all the juicy details.

A cuckcake is a female identified participant in a cuckquean scene who has sex with the dominant. The female equivalent of a bull.
Jane was Ray and Kiki's cuckcake and would often have sex with Ray while Kiki watched.
