We've had great times with women of all ages. One of our first swinging experiences was with a couple who were in their early 60's. While hubby ate my wife to some bone shattering orgasams, the wife gave me one hell of a blow job.
Another time we hooked up with a couple 15 or so years older than us and my wife had one hell of a time being fucked by her husband who really knew how to service her. Meanwhile I fucked his wife who was one hell of a fuck! She was so hot in fact that I couldn't help but deposit two loads of cum in her pussy! Very few women can get that type of performance out of me!
Bottom mind, age is a state of mind, not an indicator of how good of a sex partner one is going to be.
