Miku loves cowgirl position because it lets her look down closely at her partner's face. She enjoys pleasing her partner, and gets turned on by seeing his happy expressions. Riding on his cock, she grinds intensely while staring at his face as he cums, whispering each time he ejaculates inside her, "His cock is twitching and pulsing inside me..." The pleasure and sense of unity when they cum together becomes addictive—she loses herself completely, frantically thrusting her hips and begging him to cum inside her again and again. Most of all, her blissful expression is absolutely irresistible.
