My girlfriend takes total control of sex

My girlfriend is a real mistress in bed. She takes complete control of every move, every touch. She knows what she wants and takes it by force. She knows how to use her hands, mouth and body in a way that just makes me lose my head. She knows how to drive me to the edge and make me beg for mercy. Her passion and thirst for pleasure is boundless and I just sink into this whirlwind of passion, letting her take whatever she wants. I feel defenseless and happy in her arms, because I know that she knows how to satisfy me better than anyone else.
