An adult clip site is a website with short porn videos. Adult clip sites have videos of a length between GIFs and standard videos (GIFs being shorter in length and standard videos longer).
Adult clip sites often have short video clips of webcam models. These short clips might be highlights taken from the full cam show or they may be the full videos models have uploaded to popular clip sites such as OnlyFans.
Sometimes adult clip sites may use clips taken from webcam shows originally broadcast on Chaturbate, MyFreeCams, Streamate, and other adult cam sites.
