Christina's training - An essay for the Master

The master continued to massage the anus of the strictly constrained motionless and tense Christina. The young woman leaned forward, positioning her flawless, firm ass in a more comfortable position for the Master to access. Christina is focused on relaxing her anus, but this is not an easy task for a girl. "Honey, I see you are already getting pleasure)))" - Christina heard the satisfied voice of her beloved Master! It was humiliating, but it was true. Overcoming resistance, pressing and massaging Christina's anus in a circular motion, the Master felt a gap in the defense of the girl's trained tense muscle bundle. A tiny mouth popped out, the Master immediately felt the slack and took the opportunity to press harder and more precisely with his finger. The Master's finger slid in effortlessly, assisted by the slippery cool jelly. Christina's hot anus pulled tight around the Master's knuckles, enveloping and exactly repeating their shape. A sigh of relief escaped from under the ball that filled the girl's mouth, the whole struggle was over, a shiver of pleasure ran through her strictly constrained body, when Christina felt a pleasant and exciting sensation of smooth sliding in her anus, feeling how the Master's fingers explored her protruding anal ring, a neat wrinkled pink ring, snugly hidden in the crevice of her crotch, just like Braille, Christina's anus explored the Master's finger, reading every relief-point tactile change of shape on it.
"Well done))) Good girl)))" - Christina heard pleasant words of praise from the Master. The sheer erotic novelty ignited Christina's latent masochistic tendencies. Strictly chained Christina was now alone in all the mercy of the Master, the girl found this as the best way to be true to his praises and compliments.
