Once in the bathroom, Brendan had only a heartbeat to close and lock the door before his reptilian mistress was upon him, starting with slipping her tongue into his mouth.
It was unlike any sensation Brendan had ever felt, and, he realized, unlike any pleasure a human girl could ever hope to offer him. The finger thick dexterous tongue slid across his, around it, under it. The Y-shaped fork of her tongue was sensuous... and sinful.
Brendan mmmphed his enjoyment and gave her tongue a gentle suck, which seemed to drive the serpent wild. Her thick coils closed tight around him from shoulder to toe, and he felt the spot of warmth once more, held maddeningly close to his inflating cock. He sucked again, the snake responded by writhing and rubbing her smooth belly plates across his body, caressing and massaging him with powerful muscle.
Now there was more than fear driving Brendan's arousal, as he felt her hot and heavy breath on his face, tasted her sweet serpentine tongue. He decided to be bold, and with careful advance, he pressed his own tongue against her scaly lips. Vipress stared into her slave's eyes in surprise and gently parted her muzzle to allow him entry.
His tongue entered her mouth, the soft pink flesh of her mouth, and he saw potential. No teeth, just soft pink flesh. His penis grew harder. He decided to explore her large maw and felt, with just the top of his tongue, the two bumps on top of her mouth, closer to her lips. Just an inch behind that was a pink mandible terminating in a fearful dagger sharp tooth. Two venomous fangs, tucked away waiting to kill something. Or somebody, Brendan realized.
He withdrew his tongue, and felt dripping wetness near his penis, soaking his thigh. The snake was oozing her feminine fluids. She looked into his eyes, her face blushing, and she caressed his lips with her own. "That wasss... very brave." She admitted. "You tassste delicccioussss."
Brendan only stared, and then winced as the snake opened her mouth, flashing out her fangs as easily as one might move a finger. But she didn't bite. She was satisfying his curiosity by letting him see the instruments of death she held between her lips. Her mouth closed and she smiled. "You flinccched."
Brendan was about to respond, but the coil closest to his cock suddenly lept to the side, Vipress's cloaca striking his penis with pinpoint precision and swallowing it inside of her with a wet squish. Brendan gasped, his senses assaulted by pleasure, and Vipress shifted her weight, pushing them both to the floor with Brendan lying on top of her.
Her coils loosened, she held his leg with her tailtip, and the snake looked at him pleadingly. "What are you waiting for?!" She said sharply. "Fuck me! Assss hard as you can!"
Brendan gasped, lying on top of her on the bathroom floor, and obeyed like a good slave. For the second time, he was fucking the viper. It was even better the second time, his earlier orgasm letting him hold on for much longer and push much harder. With each ramming thrust, he felt her flesh get tighter and tighter, pulling them both to incredible erotic extremes.
The snake writhed below him, hissing her delight, taking the pounding from her human lover with lustful passion, and felt herself getting close. She threw her head onto the tile floor and let go, surrendering, as climax slammed into her serpentine body.
Brendan groaned, cried out, and let one final slamming thrust deep into her loins as she grabbed and choked his cock with her cloaca, squeezing it, milking it for everything it had, as Brendan once again erupted inside her.
With the orgasm passing, Brendan found Vipress still clenching him, locked in pleasure, and experimentally he gave another hump. She bucked right back against him and mumbled something, lost in rapture and writhing, slithering on her back. Still semi-hard, Brendan drove a few more thrusts home, punishing his mistress with prolonged orgasmic joy, and gasped as she came off a second time, squealing and hissing as she vibrated with climax.
Brendan withdrew his cock, now flaccid and useless, and sat beside her, staring at her still moistened slit. A wicked idea came to mind, and he seated that section of tail over his lap. His finger lept forward into service, and with slick ease he penetrated her still throbbing loins. His finger, unlike his penis, seldom got tired. And though smaller than his cock, he knew where her sweet spot was.
For twenty blissful minutes Brendan stroked off his mistress again and again, pushing her further and further into withering pleasure as he gave her overstimulated multiple orgasms. She would writhe, gasp, flail, and beg for more and more, her passage throbbing and swelling around his finger, soaking with her fluids. Again and again she came, until Brendan was hard once more, and for a third time he entered her. The viper was now limp and exhausted, and barely registered her slave had penetrated her until he was on top, thrusting once more with renewed vigor.
She came three more times in the process, lying back in panting exhaustion as he finished himself in her, flicking her tail slightly as he fell to the side, collapsing, and the two oversexed creatures laid, catching their breath.
Vipress turned her long snout to Brendan and only smiled. "Now..." She began. "I could usssse that sssshower."
"Me too." He panted, drenched in sweat, their joint fluids having formed a puddle beneath them.
The snake was the first to move, lazily and problematically trying to move her aching muscles. She succeeded, falling indignantly into the bottom of the bathtub, and coiled, waiting for her slave.
Brendan took a moment to swab the floor with Rick's towel, laughed, and set it back on the rack.
