I had my first real session yesterday and had decent shaking in my lower body but it wasn’t anything special. I just finished my second session today and all i have to say is WOW. Started out with that same shaking but it started at the most intense level i had yesterday about 10 min in today. After 2-3 waves of this I suddenly felt my ass clench down on my progasm and my body went into a complete flex. I began violently and uncontrollably bucking back and forth, my legs shaking up and down side to side. I could barely keep my breath and was in shock. As soon as it subsided I would have 15 seconds to catch my breath and then it would build back up all over again. This happened probably 8-10 times before i literally could not stand it anymore. Absolutely insane.
