Background
I decided to sleep in my XO “chastity cup” overnight. This is probably the most comfortable cup I have. I got a good night’s rest; about 3:30 AM I awoke to an incredibly strong erection within the cup! And for the next 40 minutes or so, I struggled with a strong yearning to ejaculate! Honestly, if it weren’t for the cup, I probably would have ejaculated. That PONR feeling was so strong and intense that I doubt I could even resist it. As I squirmed-about in bed, my cock was being slightly stimulated within the cup. But not enough to induce an ejaculation. So, once again, the “chastity cup” saved the day!
Discussion
First and foremost, a “chastity cup” prevents masturbation and ejaculation. After all, the cup (as it it used for chastity) is not there to protect the male genitals from injury, it is there for a completely different purpose. And it performs that function well! With a throbbing, aching erection, an ejaculation would be most welcome! But there is an impediment: a solid barrier to stop any touching and any masturbation on my part. The cup is anatomically-shaped so that it cradles my scrotum, perineum and erect cock. It works very well. I am prohibited from masturbating. It is an intense denial of pleasure.
Conclusion
When the erection subsided, I am still in chastity. But being in Day 6 of SR, my T-level is definitely on the rise! I can feel it! I would like to ejaculate! I feel like I want to ejaculate! My cock is aching for a release! Darn chastity cup gets in the way!
