Nope, actually it's quite flat. The thong gives an illusion to there actually being cheeks. Now, GJJ will post the perfect ass.
I prefer Stark's version. I don't like them too big. The pictures Stark posted are perfectly proportioned to sit on my face and lock everything in just right without smothering me to death.
small asses are not nearly as sexy to me, however ive had tiny ass like the first one stark posted before and it was good, there wasnt anything to slam up against, to grb onto, to shake... but with a really small ass you do get deeper penetration...
I like them a bit bigger, so
