Submissiveness

"Good… then I will start on top, okay?" Penelope licked her lips as she gained hold of Tanya and reversed her position so that her face was now facing Tanya's most precious place.

"Penny… who said you would be on top…? Shouldn't I be there? I am clearly the dominant one." 

"Pffft!" Penelope did not believe a word Tanya had just spoken. 

Penelope had become troublesome for Tanya. While Tanya would usually be seductive in nature and make almost every move an enticing show for the eyes and ears, now she had to restrain herself and act much more reserved than she usually would.

In the face of someone that was clearly more dominant than her, Tanya wanted to fight, but knew she would not succeed. Her heart felt weakness against Penelope; a different weakness to Yuri. She wouldn't be able to bring herself to fight back too hard against Penelope.
