Training and Venting
For the first time in her life, Teresa was being toyed with by someone of the opposite sex like this. If it were in the past, she would have felt immense disgust. But under the influence of the sub-star's shackles, that repulsion was suppressed.
"Stop... Please... Give me a break."
Her voice was incredibly weak. However, what terrified Teresa even more was that, perhaps due to her suppressed feelings of disgust, her body began to experience waves of pleasure instead.
On the surface, Sterl seemed to be enjoying himself, yet his eyes were cold. He certainly took action against Teresa with the intention of venting his desire.
But venting his desires was only a small part of Sterl's motivation.
Seeing the look in Teresa's eyes when she tried to stand, Sterl knew that even though she was loyal to him under the control of the sub-star, her heart was still rebellious.
