fetish
Macrophilia
A fetish for significant size difference, usually a giant or oversized partner paired with a normal-sized or tiny one, appearing in romance and erotica as giant/giantess fantasy, size kink, or monster-size couplings.
Why readers love it
Readers are drawn to the extreme power imbalance and the frisson of being overwhelmed or dwarfed by a partner, and the visual and sensory contrast gives writers room for awe, tenderness, and helpless arousal all at once.

Worth knowing: In real-world size-play or roleplay, clear limits and safewords matter because the dynamic leans on physical overwhelm and power exchange, and aftercare is worth naming in advance.
