Every trope, kink, fetish, and dynamic explained in plain language — plus real books to read for each one.
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.
A fetish in which the object of desire is a machine, most often a vehicle like a car, motorcycle, or aircraft, and usually written as a romance between a human and a sentient or magically awakened machine. In the stories, the machine has a presence, a voice, or a will of its own, and the intimacy is physical, mechanical, or psychic rather than strictly human.
Microphilia is a fetish in which a character is sexually aroused by bodies or body parts on a miniature scale, or by the fantasy of being shrunk down to that scale themselves. In romance and erotica it usually appears in fantasy or sci-fi settings, where size difference becomes the source of tension and heat.
Mirror play is a visual kink where partners use mirrors during sex to watch themselves or each other, turning the act into a shared spectacle of arousal and self-awareness. It often involves positioning mirrors to catch specific angles, deepening the sense of exposure and intimacy.
Muscle Worship is a fetish in which one partner reveres, touches, kisses, or verbally praises the other's physique, focusing intensely on specific muscle groups like biceps, abs, chest, or thighs.
