Cuckquean
A cuckquean is the female counterpart to a cuckold: a woman who is aroused by watching or knowing her partner is intimate with someone else.

A cuckquean is the female counterpart to the cuckold. She is a woman who finds arousal in watching, or simply knowing, that her partner is enjoying intimacy with someone else — often with the same blend of trust and erotic surrender.
The dynamic is far less talked about than its male equivalent, but the principles are identical: it is consensual, negotiated, and shaped to the couple's tastes. Some keep it to fantasy and talk; others involve a third partner within clearly agreed boundaries.
As always, honesty and enthusiastic consent come first. For couples who enjoy it, the cuckquean dynamic can be an expression of deep trust — and any element of playful power is simply negotiated openly.
