I love the so-called 'mature' genre in JAV. In most cases, the mature performers are more enthusiastic, and energetic (just my opinion).
Who are your favourite JAV performers? Instead of focusing on just looks, let's also look at performance (very important).
From a performance stand-point it's AYANE ASAKURA. She's loud, and intensely orgasmic. When she sucks cock, she inhales it, and savours it.
She's shapely, but not over-weight, and has an ass that was made for grabbin' and smackin'
!
When it comes to sheer beauty, I go with MAKI HOJO. Actually, she doesn't look like she belongs in the 'mature' category. She's as beautiful as (if not more so) than many of the younger JAV stars. I especially like her rich, husky voice, and her black hair.
There are others I like, but Maki Hojo, and Ayane Asakura are my top two.
