"So good... going deeper and deeper inside... Hey, am I feeling good too?" Their eyes gleam with intense heat, taking full control of my urethra. Pens, thermometers, metal rods—jammed forcefully into the tip of my cock. The erotic gazes of these dominatrices overpower me, as pleasure that controls life and death surges through my body. The sensation of urethral stimulation steadily swells my cock. I want to be trained by these cute, beautiful, yet slightly cruel girls... In this deep-sea world, I am completely dominated.
