Hyper fetish, also known as hypertrophilia or hypersexulaity, refers to the sexual fascination with abnormally large body parts, such as a hyper penis, hyper breasts, hyper ass and even hyper muscles. Hyper fetish is usually represented in hentai (animation) porn. In real life, the fetish manifests in people obsessed with artificial breasts and buttocks implants, saline injections, and overly zealous body building.
Hyper fetish is also common in the furry world. In this case, the characters are referred to as hyperfurs and may have exaggerated erogenous areas as well as an enormous tail, feet or paws.
