I have seen lots of pornstars who have done B/G who are obviously not into it, the look in Karina's eyes when she gets the guy's dick out is the total opposite, it is like she is saying- yes at last.
It is hard to tell how good a performer she will be without a bj or penetration but for what it is it is very good, she looks like she wants to give him a bj, but I guess Score are hoping she will resign with them in January & then do more gradually.
If she is not interested in B/G then why do anything on film at all? Why not just stay like Merilyn or Aria & carry on doing solo.
My hope is she will leave Score & do stuff for DDF, Brazzers, BangBros etc.
