He smiled as he heard her words, seeing her eyes, seeing the pure lust in them. He rubbed her g-spot a little more before his fingers went fast with movement, staying buried in her but flicking back and forth, pushing against her walls, making a v-shape that alternated which wall he pressed with every movement. He could feel her juices flowing between his fingers, felt them squish when his fingers passed by each other. He turned his hand, his fingers pressing against her other walls now, before he started doing long, deep thrusts with his fingers.
His free hand went to her shoulder, just below the neck, as he thrusted his fingers. He gently pressed down, trying to have her move to have her shoulders on the bed, her fine ass positioned upwards. When she did, he would be thrusting deeper into her without even changing how his hand was moving, just by the way she would be angling her hips.
