I found a somewhat similar gif here:

Really good subreddit in general, by the way. I recommend it.
I wonder if this, uh, "skill" is hard to acquire? I don't remember seeing it very much in porn so I assume it's somewhat rare.
When my wife cums - vaginally or anally - its exactly like she's trying to push my dick out of her body. HARD. She'll bend me in half most of the time, and yeah it hurts.
The best part is how she's a total sadist, and hurting me gets her off. Getting off huts me. And it gets her off some more. It's a feedback loop, and she can go on like this for a long time. I've never known her to understand the meaning of "enough orgasms." She tried ecstasy *once* and it basically resulted in her cumming continuously for several hours. She immediately realised that it was a rabbit hole down which she should never go.
So, yeah. That's sex with my wife.
