Alexcis was a willing slave, eager to please his Mistress Lilith Nocturna in any way he could. Today, she had an unusual request for him - to inflate his mouth as much as possible. He knew this was for her pleasure, and he was more than happy to oblige.
As he entered her chambers, he saw her sitting on a plush throne, wearing a regal black gown that hugged her body in all the right places. Her long, raven hair cascaded down her back like a waterfall, and her eyes gleamed with anticipation. In her hand, she held a strange device - a large, bulbous syringe connected to a long, flexible hose.
"Kneel before me, my slave," she commanded, her voice like velvet over steel. Alexcis did as he was told, kneeling at her feet as he waited for her next instruction.
"Open wide," she commanded, and he parted his lips obediently. She guided the tip of the syringe to the back of his throat, and he felt a strange sensation as the cold metal made contact with his warm flesh. There was a slight sting as she pressed the plunger, but it was quickly replaced by a rush of warmth spreading through his body.
"Swallow," she ordered, and he did, feeling the bulb of the syringe slip past his Adam's apple and into his esophagus. She withdrew the syringe slowly, still keeping a hold on his chin as she massaged his throat gently. He felt his stomach churn with anticipation, knowing that she would soon fill him up again.
And so it continued, over and over again. Each time she filled him up, she would watch with hungry eyes as he struggled to contain the massive bulge in his cheek. She would sometimes tap her foot impatiently, as if urging him to take more, and other times she would run her fingers lightly over the bulging mass of flesh, causing him to shiver with delight.
Finally, after what felt like hours, she was satisfied. "You have pleased me well, my slave," she said, her voice ringing with approval. She placed the syringe on a nearby table, and as she did so, Alexcis felt a wave of relief wash over him. His cheeks and throat were sore from all the inflating and deflating, but he knew that the pain was part of the pleasure.
"Thank you, Mistress," he murmured, bowing his head in submission. He looked up at her, his eyes full of love and devotion. She was his everything, and he would do anything for her.
