Her husband figs her. Ass and pussy. Not with the same fig and not both all the time. Usually part of a spank or caning. Not all the time but often enough. She doesn't like it...in a good way.
Another way to endure pain and discomfort all the way to orgasm is to wrap your cock with the leaves of stinging nettles. The leaves, or rather the oil from the leaves, cause an itchy and burning rash on the cock that goes away within 12 hours. The cock can be so agitated that the owner might even cum from it, hands free.
I can assure you that you can get a similar feeling to figging when sounding by using some tingle lube on the sound. If you just want to enjoy the feeling of sounding without any stinging sensation thats even better. I sometimes use a tingle lube on my sound as it goes into my penis. Feels epic. I have never tried figging though, I had to google that one.
My wife and I also enjoy a little ball play. She likes to lightly spank and squeeze my balls. It's such a turn on.
If you haven’t tried this I truly suggest giving it a go. I really like using a tight silicone cock ring around the whole package and have her blow/jerk me with intermittent light slaps to my penis and balls. Sometimes light teeth dragging.
I love it when my wife is rough with my balls. She knows just how hard to squeeze or slap them to get me super hard. Then she'll slap my hard cock as well. Sometimes she'll grab them when we're out on public and whisper in my ear "remember I own these." We've tried some light ball busting and I enjoy the submissive part of that.
My wife has started to squeeze my balls, she alternates how hard and occasionally adds some pulling. She tells me if I want to cum I have go jerk myself off, so I do She squeezes harder and softer over and over and can make me cum just from that. The hard is to the point of pain but she then stops
