This girl continues to grow on me, and probably a bunch of other people as well.
She is sensual, naughty and provocative, and totally soft, squishy and curvy in all the right places - specially those boobs, hips and amazing ass, heh heh! I love your her bikini bottoms often cut into her hips, showing how soft and juicy she is in that area. Much nicer than some of the stick insects you see around!
Love the opening sequence with the white babydoll in Sabra 2012.01.26, followed by that striped bikini with the TINY denim hotpants - such a tease in those! I also love how she often wears heels (still sadly under-used in J-gravure IMHO) such as the opening sequence of Sabra 2012.02.02 - though I'd like it if she got some heels classier than the transparent mules she often wears. Oh well, can't have everything! Just having Ayaka on my screen at all is really enough!

Edit: I was so fixated on Ayaka's body that I forgot to mention her face. She is so cute and pretty! And her yaeba tooth just adds to that, so cute! (BTW, you heard about Japanese girls getting yaeba teeth created when they don't have them - wow! - story
here)
