When my wife Barbie S. would pick up CSU students to fuck on a Saturday night at Washington's Fort Collins CO, if she could get them to come home with her, I got to watch and hear her cajole and encourage them to cum in her pussy. She always bare backed and got them to cum two or three times so I had a well fucked, cum filled pussy to eat and fuck later.
I had a neighbour that was like 25 years older than me that used to jerk me off and then just as I was about to cum she would sit on my cock and beg me to fill her womb, we never really fucked but she always took my load in her pussy. Not sure what she really got from it, she was married but had no kids maybe she was infertile. I was 16 at the time. It went on for like 2 years almost every week until I went to uni. I loved it lol
