Well, I sort of had chances to watch some porns recently.
from the old honkie martial arts movie styles, japanese old movie
with a storyline styles to 70s-90 american ones.
Then there is those anime ones.
The older ones serves up real brea-sts.
The newer american ones, somehow, just simply revolved around big
tas tas, a platform like high heels, and very clean actions.
the anime one, was kinda interesting....from ninjas with sexcraft
to monsters and mythical objects... My mind was totally warp after
30 minutes of them.
Maybe ask Bear, whether does he did a study on them during his
'convalense'?
