"It'sss not sssstopping...." Vipress hissed. She closed her eyes in bliss and Brendan could feel the warm excited breath from her serpentine nostrils against his face. He looked down and saw the snake's length wrapped around his waist three times, her body as thick as his arm, as realized how huge and powerful she was.
His fear at having the giant still growing snake coiled around him was fading as again she pulsed with another growth spurt. Brendan watched her long elegant face fly backwards in aroused delight as she got even bigger around him, his hands holding her tight against his chest as she swelled and lengthened. He was vaguely aware of a strange warmth near the side of his waist, emanating from the otherwise cool and scaly female.
Now it was Brendan's turn to blush as he realized what was happening to her. Each growth spurt was turning her on harder and harder. He was holding and being held by a giant horny snake woman. His fear faded entirely and now he was curious.
"Mistress?" He whispered, and smiled as her dazed face nuzzled against his before she pulled back to stare at him. "Yesss?" She hissed softly, her breath hot and heavy.
Brendan chanced caressing his hand across her back and watched her expression soften with pleasure. "I can tell you're aroused." He said simply.
The serpent blushed harder on her face scales and nodded sheepishly. "Thissss issss...." She paused, looking for the right words. "You have no idea, human. It feelsss... incredible."
"You're getting so big and strong. No person will ever cross you now." Brendan offered.
"Yesss..." Vipress smiled, realizing. "Yesss! You're right, sssslave. No persssson."
Her coils tightened around his waist and she put her head on his shoulder, eyes closed, practically gasping. The warmth against his side had come to a boiling point, and Brendan could feel wetness accompanying the heat. "Ahhh..." Vipress gasped, and winced. Her body tensed tightly around him, and vibrated.
Another final pulse came fast and hard. Again she grew, letting out a sinful hiss of lust next to his ear. The snake was now twice as thick as a human arm and incredibly long and sinewy. All that length was nothing but hard flexible muscle. Her head was now much larger and longer than Brendan's own hand, if there was anything to compare it by.
She held herself against him, flicking her tongue out rapidly and catching her breath. "It'sss.... sssstopped." She raised her head off his shoulder and peered down at herself, seeing her sheer size with wide delighted eyes. "That wasss.... amazing."
"Do you want me to... help you?" Brendan asked slyly. He had come to a monumental decision in his half pot baked mind. The snake was hot, the growing and her reaction had wound up turning him on, and he was starting to enjoy being dominated by her.
Vipress raised her head around to face Brendan, embraced him in her smooth leathery coils, and her expression lost all hints of the "cruel mistress" facade she had been playing since the basement. She smiled warmly, reassuringly, and for the right effect she rubbed the section of her coil on his waist that contained her warm and wet cloaca. "Yesssssss." She hissed, and punctuated by flicking her tongue slowly and affectionately against Brendan's lips. "Pleassssse me, sssslave."
Brendan needed very little encouragement. With his one hand still on her back, her gently stroked the soft gloss of her scales, tracing the contours of her smooth serpentine body against his chest. With his other hand, he stroked across her face and the top of her head, her eyes closing halfway in enjoyment. He traced his hands around her back and brought them down around his waist, stroking and fondling her coils.
She looked down towards the lowest coil on his body and her grin widened. Brendan looked down and his hand slipped between his shirt her underside. He quickly found the damp hot point and watched - delighted - as Vipress melted around him, her long scaly face blushing harder.
His palm touched the warmth, rubbed around it, and he could make out the warm opening, prominant and excited, and something deep between them.
The snake stared at him and he stared back, her eyes much more gentle and loving. "Go ahead." She said with a sweetness in her voice.
Barely believing he was doing this, not caring how fucked up it all was, Brendan took his index finger and gently probed it into the snake's soft netheregions. He felt around, getting his bearings, and was surprised by how familiar it was. Except for the odd passage that seemed to open into two holes inside of her.
The snake began laughing slightly and squirmed.
"What?" Brendan asked quickly, suddenly self-conscious.
"Y-You're tickling my anussss." She giggled.
Brendan withdrew his finger slightly and went for the other hole, blinking, blushing. "S-Sorry."
She giggled a little more and then seemed to melt against him as his finger found the mark. A slippery tunnel of tight muscular flesh. He pushed forward, and found an odd little bump just inside the passage. That could only be her snakey clit.
"Yesss. That'sss it." Vipress hissed, and once again she put her head on his shoulder, coiling around him tightly.
Slowly, awkwardly, Brendan began tracing the tiny nub's outline, and was rewarded with it swelling under his finger. Vipress growled slightly, and he felt her tense. "Yessss..." She hissed. "Yessss!"
Brendan built up a consistent rhythm and began circling and rubbing around her clit. Direct stimulation was too much for her, and it was clear from physical response she loved what he was doing. By now, Brendan was hopelessly turned on, and they could both feel his erection pressed against her meaty coils.
A few more strokes on her most sensitive parts and Brendan's finger was suddenly swallowed up by hungry pulsating flesh. Vipress let out a rasping hiss and threw her head back, cumming hard. They both fell back onto the bed and the snake coiled herself around Brendan's body, writhing against him and rubbing a section of her tail on top of his groin as she orgasmed from his touch.
Withdrawing his dripping finger, Brendan found white creamy fluid all over his hand. The snake raised up slightly, staring down at her human slave, and her face took on a demonic grin.
"Time to reward my ssssslave for such devoted ssssservice." Brendan layed helpless pinned under her size and strength, coiled in her scales, and gulped.
