When the mood you're in doesn't match the circumstances to appease it.
When you're in the mood to take out your frustrations on a willing woman. But not just any woman. Not all women can handle that kind of treatment. This sort of thing requires a special kind of woman.
The kind of woman that can handle a truly merciless and remorseless throat fucking. That will lay with her head hanging over the edge and just take it. The kind of woman that isn't just able to handle the treatment, but enjoys it even.
This wouldn't be a gentle event. It would be rough, forceful, and violent even. Repeatedly forcing the cock down her throat, not minding the gagging and choking. Even enjoying it. Starving her of the ability to breath as you use her throat as a fleshlight. Pushing all the way down regardless of how she struggles. Then at the last moment pulling out so she can swallow a huge gasp of air then have her mouth filled again.
Using this woman's mouth for your own enjoyment and pleasure and release in any way you see fit. Make her gag and choke, smother her and make her show off her tongue skills, hold your had around her neck as you bottom out in her throat so you can feel it bulging. Then to finish up you fill her mouth, holding her all the way down and making her swallow everything she can.
This is the kind of mood I find myself in. Unfortunately I'm also in a situation where there is not woman around that can appease it.
The struggle is real.
