In my experience, women in their 40s and early 50s have an absolutely insatiable appetite for sex. The term cougar is an absolute truth and I can tell you first hand that women of that age can really get it.
I am in my early 30s and I used to work with a woman named Tuesday. She is about 15 years older than me. Tuesday is about 5’2”, curvy body, fake tits (not huge, but you can tell they are fake) blonde hair and glasses. When I met her she had just gotten divorced, and it was very bitter to say the least. We worked together at a real estate company. She would walk by my desk and make conversation and flirt with me a bit. She used to wear these sexy black skirts and tops that showed just enough cleavage for me to notice.
