There's a classic video of Demi Scott (aka Mercedes) doing naked JOI back when JOI was a fresh idea brought on by the help of Wank It Now. The erotic thing about this video is Demi's encouragement to blow your load while she's naked, boobs swinging.
Sofia Venko proves she really is a PAWG with her honey haze stare and perfectly big boobs she displays on Met Art. There is something about babes that read which just turns me on, probably the erotica part.
