As an older gentleman, I appreciate women and their bodies. I believe taking ones time pleasing them gets better as you age for some reason. Older/younger sex is a definite turn-on and for a woman to tease a man in public is healthy; it keeps each other young at heart so why not do it.
Being a very visual person, hearing and seeing a woman orgasm while masturbating is incredible. Pleasuring a woman whether it's through oral, spanking or whatever it might be is definitely open to experimentation.
Even though it's taboo to a lot of people, family experiences carries a certain amount of excitement to say the least. It hasn't happened to me but it's quite a turn-on and I definitely enjoy reading about it.
