Well, Alley obviously isnt comfortable with the full scale Penthouse type explicit poses. I have always been willing to give her a pass on that, since she is better than most softcore models at keeping her fans honest with what she is comfortable with. She only does the sexier open legged poses some of the time, so theoretically fans shouldnt get bored with it. The good news is that recently she seems to being doing those types of posing more often than she has done them in the past.
But I have to admit that after 10 years it is slightly disappointing that her boundaries havent expanded.
