Layla was my introduction to hysterical lit -- as well as quite a few other kinks -- when I first joined the site, so it's particularly nice to spend some time with this. Her delivery is expressive and coherent, keeping it together enough for us to get into the (quite risqué and explicit) story as well, but you're in no doubt the intensity is building all of the way through.
It's a lovely example of the genre: the framing focuses all of the attention on reactions, there's a book recommendation, and in common with a lot of her other vids she cums like a bottle of fizzy pop being gently but persistently shaken. If you already like this sort of thing or are in the slightest bit curious, check it out. :)
