Steel laughed and tossed her head to guide her hair away from the tender flesh under the attention of her teeth. Hips and breasts ground harder and harder against each other with every buck and attempt to toss the gray woman from the pinned student. Fingers dug and locked into the dirt to stabilize the creature as she bent in to bite and whisper again to Susan.

"Of course... it's fun... Mnnnhggaaah! Oh Gods! Harder! Sh- show me how much fun you're having!"

Two flickering tongues continued to graze and tap at the woman's writhing flesh, and the mechanical serpent connecting the two wet cunts clicked loudly and began trembling and vibrating of its own accord. A hungry moan erupted from Miss Steel's lips before she clamped her mouth over the curve where neck met shoulder and scratched softly at Susan's skin with sharp teeth.

Susan twisted her head to the side as the creature leaned in again, trying to avoid it as much as possible. "I'm not... having f... fun, you bitch. Ahh! Get off meeeeEEEE!" As she ended her protest, the snake inside them started vibrating, and she was reduced to moans of combined pleasure and anger.

The gray woman laughed darkly and bent close to kiss almost tenderly at Susan's cheek. "You sound like... you're having... nngghh... fun." Teeth delicately nipped at the trapped girl's neck as hips crashed hard together to drive the vibrating serpent deep into both of them. "You move... like it... too." Miss Steel panted and moaned loudly as she ground herself tighter into her prey, tasting her mingling lust and anger, and working her own pleasure higher.

Susan tried to squirm out from under the monster, but its grip was too strong for her. "Nnnnn... No. Stop... aaaaAAAAAAGGHH!" Her cry became one of pain as Miss Steel forced the snake deeper into her.

Pain! It was a whiff of that perfect drug in the gray woman's mind. She hissed and arched her back with the intoxication of it and worked her hips harder and harder against Susan's.

"Scream, whore!" Words seeped like steam from her half-clenched teeth, and the forked tongue flicked out against the girl's soft neck once more. "Scream and beg!"

"Not going to... aah... beg. Won't give you... uhn... the satis... faction... AAAAAAAAH!" She cried out and her back arched as the creature thrust into her hard.

Despite her protests, she could feel her cunt growing moist from the monster's actions.

"Mnnnnngghffine! Fine then!" the gray woman hissed as she dug her hips harder and tighter against Susan's. "Just... ah... scream."

Fingernails, sharp as fangs, dug softly into the student's shoulders from hands clamped down on her, pinning her against the cool, soft grass.

Susan's cries became a mixture of pain and pleasure as the creature forced the snake as far into her as it could go. The mixture of sensations overwhelmed her to the point that she could no longer respond to the thing's taunts.

The gray woman moaned and slammed her hips harder and harder against Susan's to shove the mechanical, solid serpent between their two cunts. Juices mingled on the smooth metal scales as Miss Steel worked herself higher and higher in bliss against her prey.

Susan began moaning faster as the monster ground against her. Despite her resistance, the creature had almost driven her to orgasm.
