Christina's training - An essay for the Master

After liberally applying lubricant to his index finger, the Master crouched behind the young woman, completely out of her line of sight. Christina could not see the Master, but the Master had an unhindered view of her elastic fleshy globes floating in the air and wrinkled, wet from arousal labia lustfully exposed to him. The master enjoyed the erotic view of the feminine and flawless beauty of his slave.
For the girl, time flowed slowly, minutes seemed to pass. Christina waited, but nothing happened, a feeling of uncertainty and fear washed over her. The young woman did not have to wait long, she felt Michael's hands stroking her ass. "Now relax Christina, it's going to be cold and weird." He placed his fingers on both sides of her anus, pulling hard on the skin. The Master's hand slipped between Christina's cheeks, feeling the tiny bud. His finger in cold jelly touched her shriveled little anus. Cristina's body twitched in response. "Hush, little one, the Master will take care of you. I will put a good finger on your tight little ass. Honey, I want you to relax your buttocks. I can't feel your anus if you squeeze it))" Master ordered.
Although this procedure was a common ritual for a girl, it was not an easy task, Christina tried to relax her sphincter, but feeling the pressure of a cold finger on herself, he instinctively strained, disobeying Christina.
The master began to slowly and gently massage, rub the girl's anus, which was slimy from the gel, with rotational and crushing movements of the index finger, feeling the smallest details and unevenness of her intimate elastic tubercle, sending a shiver of tingling excitement through Christina's tightly bound figure "Oh! Yes, what a sweet little thing it is," - the Master continued, gently massaging the receptive tubercle of passion. Christina froze in tension, the girl could not deny that the skillful finger of the master mysteriously aroused her sexual feeling. Cristina squeezed her tight hips together and involuntarily moaned into her big ball gag.
"I know honey... You like it... But don't be so impatient..)))" It was true and humiliating, Christina couldn't do anything with her arousal! The master kindled a flame in Christina and kept her on a thin line. The girl was under complete control and in the complete power of her loving Master, and could not influence what was happening to her in any way.
