Umi's hand shot up as she smiled, her tail slithering with anticipation. "I'd like to try a bit, Ms. Tail!"
Ms. Tail frowned a bit, seeing that now she had to postpone her meal. "Ok then, Umi. Let's see how you do."
Hydra's heads scowled a bit, regretting not being quick enough to volunteer. Umi got and and slowly slithered to the front of the room, licking her lips as she approached the wide-eyed Yoko. Yoko knew how strong naga's were, but Umi wasn't just strong, but merciless. She cringed a bit, knowing she was going to be swallowed by the smiling naga.
Umi stood in front of Yoko, and her tail quickly wrapped around Yoko's body, squeezing tightly. Since this was going to happen no matter what, Yoko simply gulped as she was raised into the air, looking down at Umi's eager face.
Ms. Tail wiped a bit of drool off of her face as she imagined what would have happened had she gotten to Yoko first, then she turned to her students. "Umi will now demonstrate how to down prey and subdue them. Take note of her technique."
Umi grinned even wider. "Thank you for the meal." After that she opened her mouth wide, her tail holding Yoko so her head was turned to her mouth. She slowly lowered the human towards her open maw.
Yoko sweated but kept calm. It was natural to be inside someone during this class, ever since she was enrolled, she had been used for all demonstrations rather than the mannequins in the back of the room. Ms. Tail reasoned that is was to give the students "A life-like experience," while really she knew that it was so that the teacher or any student could gobble her up.
As Yoko's face neared Umi's mouth, Umi's tongue lashed out and started licking her. Yoko closed her eyes and turned her head a bit as the naga tasted her. Soon her head was in her mouth, Umi's tongue licking her neck and chin. Yoko looked down the familier back of Umi's throat, which was as dark as a black hole. She moved further inside, and feels the tail around her unravel as her shoulders enter the mouth. Yoko sighed a bit. She kept telling herself it would be over soon, as it usually is. Her arms enter , and she feels herself slowly going down the throat. She feels Umi's tongue slightly rub against her chest, and hears Umi moan a bit.
Soon her arms and hands are unraveled and inside the mouth. Yoko continues to fall into the throat, her head pressing against the fleshy walls. Umi was dragging this meal out, like usual. As her waist enters the mouth, she feels the tongue glide against her crotch strongly. Yoko blushes, knowing Umi loved to tease her like that, making her enjoy it less. She sighed in relief as she feels her waist pass, moving to the legs. Her head finally reaches the stomach. She nods as she knows it is almost over. Umi's tongue glides around her legs as she slurps them up slowly, and with a final gulp, Yoko's entire body is forced into the stomach. Umi rubs her belly, satisfied with her meal.
Ms. Tail nodded. "Very good, Umi. That was fantastic."
Umi takes a small bow and rubs some more. Yoko sits in the stomach, waiting to be let out like normal.
Then......
