Noun: the additional male participant to a male/female couple during a MMF threesome and a variation of the traditional cuckold MFM threesome. In this variation, the female, cuckquean, enjoys the humiliation of watching her male partner, the queanbull, have sexual contact with another man and does not participate in the interaction. The cucktart is the male counterpart to the cuckcake, the additional female, who has sex with the queanbull, while the cuckquean watches.
That cuckquean, Eve, really enjoys watching her queanbull husband, Adam, fuck that little cucktart, Steve.
