Last Chapter Recap: "D-Doc...?" Natasha gasped, her face flushed bright red in shock.
NOW
"Fufufu~" Ivanna smiled, her voice low and playful. "Just enjoy yourself, Ensign..."
Revealing her perverted side, Ivanna begins caressing Natasha's genitals and nipples in thoroughly sexual act.
"D-Doc..." Natasha murmured, her voice unsteady. "I feel weird..."
"Does it hurt?" Ivanna asked playfully, a teasing glint in her eye.
"No, just..." Natasha said with a faint moan. "You're acting strange..."
Do you dislike it, Natasha?" Ivanna whispered, leaning in close and gently biting her neck.
"No—ahhh~ just... he—" Natasha stammered, her face burning. "Ensign is watching..."
"Fufu~ That's right," Ivanna giggled, her eyes glinting mischievously. "Does it excite you, knowing he's watching?"
"Ahhh~ I... I don't know at this point~" Natasha whispered, her voice trembling with confusion and heat.
Completely unable to gather her thoughts, Natasha easily lets Ivanna loosen the suit, revealing a set of perky breasts, their nipples are already erect from all the teasing.
"Fufufu~ Show him…" Ivanna licked Natasha's neck, her voice laced with mischief. "Show him how lewd girl you are, Natasha~"
"No, I'm… Ahhhh~" Natasha moaned loudly, "It feels good~ ahhhh~"
Her moist eyes meet with my gaze, as Ivanna continues to caress her body. The sight is so erotic, I feel intense urge to mate. However, that could be too much even in her current state, so I restrain myself.
"D-Doc... Hmmm~ something… is…" Natasha gasped for breath.
"Are you coming, Ensign?" Ivanna asked while quickly licking her neck.
"Co…ming? Y… Ahhh~ yes… Hmmm~ almost~" Natasha moaned continuously gasping for air.
"Nooope~" Ivanna said in a strict and smirking tone. "You can't cum without master's permission, Natasha~"
Having said this dangerous thing, Ivanna suddenly stops her movements, leaving Natasha hanging on the brink.
"D-doc... W-why…" Natasha said, stammering.
"Fufufu... orgasm is reserved for good kids, Natasha~" Ivanna said with a mischievous smile. "However, I have some good news..."
"Eh... eh?" Natasha stammered, unsure of what to expect.
"You'll be a good kid soon too~" Ivanna said sweetly, her voice laced with a teasing.
Just as Ivanna finished her sentence, Natasha's body fell unconscious, overwhelmed by all the chemicals and sensations it was subjected to over last few minutes.
"Damn, Ivanna..." Adam said, clearly impressed. "I didn't think you had it in you."
"I hope you enjoyed this little tease, Master~" Ivanna said with a playful glint in her eyes.
"Damn right I did!" Adam said with a grin. "Now I have this raging boner, and we have to carry this girl to the machine!"
"Fufufu, a little patience, Master~" Ivanna said, her voice silky. "This slave will take fuull~ responsibility for your boner later on."
With expression of pure delight, Ivanna helps me carry Natasha to the secret room, just as yesterday.
Secret Room
After placing Natasha onto the machine and adjusting the instruments, Ivanna stepped back. Adam glanced at the readings, then commanded firmly, "Ava, begin Stage Two of the slave maker!"
"Enjoy your reward, Ensign Natasha! Hahahaha!" Adam laughed madly, his voice echoing through the secret room.
"Slave maker machine Stage Two activated," Ava said.
With usual humming, the machine resumes Natasha's brainwashing.
Unlike Ivanna, who had a gorgeously soft body from the start, the muscular physique of a fighter pilot requires more altercations. In the beginning, a special agent is injected to her veins, softening her muscles, while her strength increased threefold.
It would be no good if she lost part of her skills in the process after all. Furthermore, the more muscles she has, the greater pleasure she can receive as a result of enhanced sensitivity.
That's doesn't involve pussy however, which is relentlessly assaulted by piston, forcing stiff walls inside her to soften in order to properly receive my dick.
"I like your bosom, Natasha..." Adam smiled, his eyes gleaming. "But there's no pair of tits that could not be made better by enlarging them."
(A/N: Just to clarify, these are not artificial tits like silicon, but the real, original skin that enlarges due to the serum's effects.)
While her breasts are being filled with milk, the machine has begun branding her with a lust crest, which will make her impossible to escape never ending carnal pleasure.
Plus, of course, a strawberry on top. Assault of ultra-waves on her brain, reprogramming her rationality into something more suitable of my sex slave.
Soon, my average face will become the visage of the most handsome man in her eyes… and her brain will go into overdrive at mere sniff of my odour. My presence will put her immediately in a happy, pleasurable mood.
"Ahh~ Ahhhh~" Natasha moaned in pleasure of the piston.
"Fufufu… fall, Natasha~" Ivanna giggled, "become sow in heat for master, just like me~"
So says Ivanna while devilishly slurping my dick, aroused as I am from her sight.
The night is still young… and I know one better method of recharging my batteries than good sleep… hahahahaha!
