Threesome
A consensual sexual encounter involving three participants, often arranged as a couple inviting a third or a temporary dynamic where all three engage together. In romance, this usually carries heavy negotiation and emotional fallout as much as heat.
Why readers love it
Readers are drawn to the taboo thrill of adding another body to a familiar pair, plus the delicious tension of jealousy, possessiveness, and the unexpected ways two lovers handle sharing. It is a fantasy of ultimate trust and depraved spontaneity rolled into one scene.
