the oldest woman i've been with is my wife cause i'm old too, haha... so let me share a story from my younger years.
when i was in my late 20s, i met this 46-year-old nymphomaniac. she was divorced with 2 grown kids and living on her own doing quite well. i met her on adultfriendfinder actually. she was local to me and i had wanted to do the whole cougar thing. her body was nowhere near 46 but you could see it in her face. she totally loved getting fucked and had no issues getting very wet well before my dick ever got into her.
looking back now, i was totally being used by her for sex and more sex, haha. not sure how i would have reacted if i figured this out back then but thinking about it now, i'm glad. she was totally open with her sexuality; more open than any woman i've ever fucked. it was refreshing and so much fun. she set a new standard for me since.
older women are much funner in my opinion. you don't have to train them, they know what they want, and not afraid to ask or take what they want.
