Peter leaned forward and kissed her.
The kiss was slow at first...warm, tender, almost reverent.
Their lips moved together gently, exploring this brand-new sensation for her.
Cortana sighed softly into his mouth, her hands sliding up to rest on his chest. But the longer it lasted, the more the fire caught.
Her fingers curled into his shirt as the kiss deepened, growing hotter, wetter, more desperate.
A low, needy moan escaped her when Peter's tongue slipped past her lips to taste her properly.
He took his time savoring her.
Every slow stroke of his tongue drew another shiver from her body. His hands roamed down her back, caressing the smooth, flawless skin of her new form before settling firmly on her bare ass.
He squeezed the soft, supple flesh, pulling her closer until her breasts pressed against his chest.
When they finally broke apart for air, both of them were breathing harder.
"I've waited so long for this…" Cortana whispered, voice already trembling with need.
"Me too," Peter murmured against her lips. He kissed her again, deeper this time, while his hands kneaded her ass more possessively, spreading her cheeks and letting his fingers tease along the sensitive skin between them.
Cortana gasped and rocked her hips against him instinctively. "Peter… touch me more. I want to feel everything."
He lifted her effortlessly, her legs wrapping around his waist as he carried her to the chair. Sitting down, he settled her on his lap so she was straddling him.
The kiss never fully stopped....it turned into a series of heated, open-mouthed kisses, broken only by gasps and soft moans. His hands never left her ass, squeezing, caressing, occasionally delivering light, teasing slaps that made her jolt and whimper.
Each little smack drew a sweeter sound from her. Cortana's breathing grew ragged.
"More…" she breathed between kisses. "I like that…"
Peter pulled back slightly, one hand still gripping her hip while the other rubbed slow circles on the cheek he had just spanked.
"You like being spanked, baby?" he asked, voice low and teasing as he gave her another firmer smack. The sound echoed softly in the lab.
"Ah~!" Cortana's eyes fluttered. "Yes… I do.... It feels so good…"
He smiled darkly and spanked her again, a little harder, watching the way her body jolted and her thighs clenched around him.
"That's my good girl," he praised, voice dropping into that deeper register she seemed to love. "You've been waiting so patiently for Daddy, haven't you?"
Cortana's breath hitched sharply at the word. A visible shiver ran through her, and she bit her lip, nodding eagerly.
"Yes, Daddy…" she whispered, the word sounding almost sinful coming from her lips. She rolled her hips, grinding her wet pussy against the growing bulge in his pants.
"I've been such a good girl waiting for you. Please… spank me more."
Peter groaned softly and delivered a series of firm, rhythmic spanks, alternating cheeks while his other hand held her waist steady.
Each impact made her ass jiggle beautifully and pulled desperate little moans from her throat.
"Such a perfect little ass," he murmured, rubbing the warmed skin soothingly before spanking her again.
"Made for Daddy's hands to hold, knead, spank... You're getting so wet already just from this, aren't you?"
Cortana whimpered, nodding frantically as she kept grinding against him. "Yes, Daddy… I'm so wet for you. Spanking me makes me ache. Please… I want more. I want you to punish me if I'm bad~"
Her voice had taken on that sweet, needy, slightly mischievous tone....the perfect mix of innocent and filthy that made his cock throb.
Peter gripped her blue hair gently and pulled her head back so he could look into her eyes while his other hand continued spanking her in slow, deliberate strokes.
"Tell Daddy what you want, baby girl," he commanded softly, voice thick with lust.
"Use your words."
Cortana's cheeks flushed darker blue, her eyes glassy with arousal as another firm smack landed on her ass.
"I want Daddy to keep spanking me… and then use me," she moaned, voice breaking beautifully. "I want to be your good little girl… but I also want you to make me take everything you give me…"
Peter smiled at her eager, needy response and brought his hand down again in a sharp, satisfying smack that made her gasp loudly.
"That's right," he murmured, voice low and rough with arousal. "You're Daddy's perfect little girl now. This body was made for me… but I still need to see the real you."
Cortana whimpered as he continued spanking her in a steady rhythm, each slap landing harder than the last. Her ass was growing warm and pink beneath the blue skin, and every impact made fresh slickness drip down her thighs.
"Yes, Daddy~" she moaned, pushing her ass back shamelessly for more. "I'll be whatever you want… I'll change for you. Just keep spanking me, please— Ahh!"
He gave her several more firm spanks, alternating sides while his other hand stroked her spine soothingly. The contrast between the stinging pain and gentle touch was driving her wild.
After one particularly hard smack that made her cry out, Peter suddenly stopped. He gripped her hips tightly and lifted her off his lap, turning her around and pressing her front down against the cool work table. Her breasts flattened against the surface as he pinned her wrists above her head with one strong hand.
Cortana let out a long, erotic moan at the new position, instinctively arching her back and presenting her reddened ass to him.
Peter leaned over her, pressing his hard bulge against her soaked pussy from behind. He rubbed slowly, teasingly, coating himself in her wetness while his lips brushed her ear.
"Even if I wanted to fuck you right now," he whispered hotly, "I won't."
Cortana groaned in frustration, trying to push back against him. "Why? Daddy, please…"
"Because you're not the woman I fell in love with." He kept rubbing his thick cock between her ass cheeks, sliding it torturously against her dripping folds and tight little hole. "Think about your old appearance. Let the X-Gene do the work. You have sixty seconds."
Cortana's eyes widened, a mix of desperation and arousal flooding her new nervous system. The constant teasing pressure of his cock made it almost impossible to concentrate.
"Peter… I can't focus when you're doing that— Ah~!"
"Sixty seconds, baby girl," he said firmly, still slowly grinding against her. "If you don't manage it, you get nothing."
She closed her eyes tightly, biting her lip as she tried to concentrate. Every slow drag of his cock against her pussy made her whimper and shudder. The pleasurable torture was overwhelming.
"Five seconds…" Peter warned, rubbing a little faster.
"What?! No! Daddy, please— I can't— Just fuck me!" she begged, voice cracking with need. But when she saw his serious expression, she squeezed her eyes shut again and focused harder.
"Four… three… two… one—"
"I did it!" Cortana cried out in triumph.
Peter watched with dark satisfaction as her body responded. The last traces of her previous pale skin shifted completely into that deep, beautiful blue. Her hair followed, turning the same striking shade. The transformation was flawless....exactly the Cortana he had fallen for, now in physical form.
"Perfect," he growled in her ear, rewarding her with a much harder thrust of his cock between her thighs. "Such a good girl for Daddy. You deserve a big reward for that effort."
Cortana shuddered hard, moaning loudly as he rubbed faster against her.
"Yes! Ahh~ Faster, Daddy— rub faster, please— Ah! Yes, that's it~!"
He spanked her again, hard enough to make her jolt forward on the table.
"You like when Daddy gets rough with you, don't you?" he asked, voice thick.
"I love it!" she gasped. "Spank me harder, Daddy! I've been such a needy little girl waiting for this cock…"
Peter obliged, delivering several sharp, stinging spanks while continuing to slide his cock against her dripping pussy and ass. Every slap made her moan louder and push back desperately.
"Tell Daddy how much you want it," he commanded, pulling her hair just enough to make her arch beautifully.
"I want your cock so bad, Daddy~" Cortana moaned, voice dripping with lust. "I want you to destroy this pussy… Please use your little girl. I'll be so good for you… I'll take everything Daddy gives me."
