I'm not getting enough exercise, so I asked a popular trainer to give me one-on-one instruction. I thought the teacher would be a muscular guy, but it turned out to be a tall, busty beauty with an amazing figure! My dick heats up with her enthusiastic instruction with her G-cup big tits pressed against me! "Don't move!" she says as she straddles my dick and pounds me into a full-automatic piledriver! She squeezes out the cum while tasting it over and over again! I didn't have to move my hips, and I was replenished with hot semen protein deep in my vagina many times!
