I'm a guy in my mid-60s and wife just 18 months younger. November has been a good month so far - 5 PIV sessions so far not to mention masturbating throughout the month.
Couple of weeks ago I decided I needed a morning "session". A little foreplay, a little oral from her, and she wanted me inside. I squirted a teaspoon of lube from the dispenser which I keep on the nightstand and applied it to both her and me. And the, we began. Slow and first, somewhat loving, and then something came over me and I went to Pound Town. 30 full minutes of just pounding away. She kept spreading her legs, holding herself apart, and groaning happily so I'm quite sure she was enjoying it as well.
When she finally had enough, she reached under her leg and starting teasing and tickling my balls. When my nuts start to contract and she teases/tickles, I'm pretty much lost. I exploded inside her and collapsed. So, a 30-minute pounding is an epic session for me.
Normally, I'm a 15-20 minute guy. However, my wife controls my orgasms. She's able to squeeze her pussy and tighten on me (which, BTW feels AMAZING!) even at her "mature" age. As I stated, when she's had enough, she'll reach down and tickle/tease my nuts - that puts me over the edge EVERY SINGLE TIME.
