The porn video tag "anal-twinks" has two main components: "anal" and "twinks".
"Anal" refers to sexual activities involving the anus, usually in the context of anal penetration or stimulation. This can involve different types of sex acts like fingering, licking, or using sex toys, but typically with a focus on penile-anal penetration.
"Twinks" are young, slender men who often have a youthful appearance. They are typically around 18-25 years old and have a slim build, smooth skin (either naturally or through hair removal), and boyish good looks. Twink porn often features scenes with two or more twink actors engaging in sexual activities.
So, the tag "anal-twinks" describes a video featuring young, slender men participating in anal sex acts. This type of content is particularly popular among those who enjoy seeing attractive, youthful men engaging in intimate activities.
