I love how naughty and dirty it feels to be exploring someone's tight little hole with my tongue and fingers. And when it comes to sex, there's nothing quite like pounding someone's tight ass until they're screaming in ecstasy.
In anal hentai, the female character is often shown to be enjoying the experience, sometimes even reaching orgasm as a result of the anal stimulation. This can be a contrast to traditional hentai, which often focuses on the male character's pleasure.
While anal hentai can be found in both manga and anime, it is more commonly found in manga. This is likely due to the fact that manga is less censored than anime, and thus can feature more explicit scenes.
