Elena takes learning quite seriously. Every bit as much, she takes pinning a slave's face quite seriously too. For her class, she needs to get her reading done, but a desk chair just isn't good. Instead, she sits on Del's chest, establishing her mastery over him. Elena then slides up sitting her delicious pussy and ass full weight on his face, while pinning his arms with her knees. She is totally indifferent to his need for air as her luscious full weight sits squarely on his face. The semester is just beginning and Elena knows how to put that ass in assignment.
