I woke up incredibly horny this morning, and decided to do my morning ritual naked. Part of this involved hanging upside with gravity boots. As I was hanging from the bar, I slowly started to stroke my cock. The sensation of all the blood rushing to my head and my dick was amazing. After only a few minutes...I started to feel dizzy and I quickened the pace. I came all over my chest and face and just layed dangling upside down until I could muster up the strength to pull myself back up.
It was an amazing orgasm...give it a try if you ever get a chance.
