Fleur loved how absolutely wet Tracey was. It was a definite turn on. The way that Tracey was looking at her innocently was one as well. IN fact, it reminded her of another cute blonde...
Lavender. She knew she shouldn't be doing this, she had Lavender. Bout as much as she knew she could, her human side couldn't regain control and her Veela still lead her body to do wicked things to the blonde student on her lap.
Taking the hand that wasn't inside Tracey, FLeur moved it to the girl's waist. "Move your 'ips like zhis..." she whispered huskily as she guided Tracey's hips to roll just so as she pushed her fingers in and out of her for the greatest effect.
Fleur was now completely lost to her Veela, who, in it's mind, was fucking Lavender since that was who it smelled.
