DASS-726 - I repeatedly ejaculated during a fully automated pile-driving session with a sweaty fitness trainer, without moving my waist even once, a very rare occurrence.

Due to my lack of exercise, I requested one-on-one training from a popular trainer. I expected a muscular instructor, but was surprised to find a tall, beautiful, and busty woman! My penis became aroused by her passionate instruction with her K-cup breasts pressed close. "Don't move!" she said as she mounted my penis and performed a fully automated pile-driving motion! Deep penetration and multiple ejaculations, 14 times! I didn't move my waist, and repeatedly swallowed hot semen protein deep inside her vagina as a supplement!!
