With a slow, deliberate rhythm, my aunt began to press her hips against my throbbing dick. My glans, slick with precum, eased into her waiting, warm womb.
"Yes, just like that. So slow. Feel my glans gently stretching your womb."
A shiver ran through her as my glans slipped further inside. Her pussy juice gushed, a fountain of desire, as her mouth fell open, gasping for air. "Ohhh... Leo... aahhh..."
When my glans was halfway in, I commanded, "Now, stop. Pull your hips away, real slow."
Fearful of displeasing me again, she obeyed, drawing back until my glans was out of her womb. "Mmm... ngghh..." she whimpered softly. Then, I instructed, "Now, slowly, push your hips back in. Take my glans inside, just like before."
I wanted to penetrate her fully; every fiber of my being yearned to plunge deep. But this was her first time, and I wanted her awake, alive for every sensation. I wanted her to remember the precise moment her womb was claimed, the exquisite climax that would ripple through her from within.
I was conditioning her, preparing her body to embrace the full force of my penetration.
"Exactly like that. Remember this feeling, aunt. Go slow. Savor every exquisite moment as your womb stretches, slowly opening for my dick."
Her womb clung to my glans from all directions, a deliciously sticky embrace of her juices and my precum. And I, too, savored the illicit thrill of corrupting my aunt, a married woman in her prime. "Aah... so tight, Leo... nghhh..."
The forbidden nature of our connection sent delicious tingles through my body. My heavy balls, already aching, began to swell with anticipation.
My aunt, still panting like a wild thing, remained on all fours, bearing my weight. Her body trembled uncontrollably, her wet, tight pussy squirming around me, silently begging for a faster rhythm. "Please... faster... aahhh... Leo..."
"No, just like this, enjoy the feeling of your womb opening slowly. You will feel real pleasure as it opens slowly."
She followed my every instruction. After twenty minutes of this tantalizingly slow penetration, her womb began to gape, flickering around my glans. This was the moment I'd been waiting for, my own release held firmly in check.
"Aunt, you're magnificent. Aaaaaaaaaaaaaah, my balls are bursting now. I'm going to cum any moment."
"Yes, Leo, aaaaaaaaaaaah, don't stop... You can cum aaaaaaaaaaaaaah, cum any moment, aaaaaaaaaaaaaah, inside my womb, aaaaaaaaaaaaaaaaaah," she moaned, her voice thick with desire.
I gripped her head, twisting her face towards mine. The raw beauty of a mature, married woman coming beneath me was breathtaking. Her eyes clouded with pleasure, her lips parted in a blissful moan, and her face glistened with desire. That sight alone sent a powerful surge through my balls, my semen rising.
"Now, take my whole glans inside your womb. I will fill it with my semen."
"Yes, Master," she breathed, her eyes locked on mine.
I kissed her twisted face, and she surged backward, taking my entire dick into her womb. Her womb, experiencing such penetration for the very first time, convulsed around my glans. "Oh! Ahhh! So full! Nngghhh!"
A violent tremor shook her as she began to pee and squirt simultaneously. "Aieee! Ah-hah! Oh my god!"
I devoured her lips, our tongues dancing, our saliva mingling, as I unleashed the floodgates.
My semen surged from my balls, pouring directly into her womb for the very first time. The direct inundation made her shake even more, her climax erupting with renewed vigor. Her hips gave way, collapsing onto the bed. "Aaaaaaaaaaaah! Yes! More! More!"
Clutching her close, kissing her deeply, I fell with her. This pushed my dick even deeper, pressing against the upper wall of her womb. My entire dick was buried within her, pushing against that exquisite obstruction, cumming directly into it. The upper wall of her womb felt like a delicious barrier, electrifying my senses. I released my semen harder, forcing it against that upper wall.
To keep her conscious, I began to tug at her nipples, already engorged and red. I pulled my lips from hers.
"Don't faint. Remember this feeling. It's only going to escalate. Just take my semen inside for now. I've held it back for so long; this will be a deep, long ejaculation."
I kissed her again, my dick twitching inside her pussy. My urethral opening, pressed against the top of her womb, continued to release my thick, sticky semen. "Ngghhh... so much... aahhh..."
My aunt, as ordered, clung to consciousness, wetting herself repeatedly, moans escaping her lips as I kissed her. "Ohhh... Leo... never felt this... aahhh..."
When my balls were finally empty, I released her lips. As semen began to leak from her womb, I thickened my glans, blocking its escape. Her womb was completely stretched, protruding visibly from her stomach. The pressure of it against the bed intensified the sensation.
A message flashed in my mind: "Using Sextony, your stats have increased. Scroll for more details."
I decided to check it tomorrow; it was far too late.
"My womb, it's aaaaaaaaaaaaah, completely stretched and filled with your semen, Leo. Aaaaaaaaaaaaaah, you came so much. Aaaaaaaaaaaaaah, it's like you gave me an enema inside my womb. Aaaaaaaaaaaaaah," she gasped, still shaking.
"From now on, follow my lead, and this feeling will keep on escalating. That was just your hips moving. Imagine what will happen when I pound my big dick inside your hole."
At the thought of our future encounters, she tightened her pussy around my still-hard dick. "Ohhh... yes... I want that... nnghh..."
"Hold on, Aunt. It's gotten too late. Your punishment took too long. The sun will be rising soon."
She glanced at the window. It was almost dawn. A look of playful disappointment crossed her face; it seemed our serious fucking had only just begun. "But... I want more..." she pouted softly.
Seeing her expression, I offered, "Want to sleep here tonight, just like this?"
Having conquered my aunt, I felt no fear from anyone in the house. She was its matriarch, and her power in this house was absolute.
"Yes, I would be happy." Like a newlywed wife after her first night, she replied, embarrassed and delighted.
I kissed her again. Gently, I reduced the size of my glans and slowly withdrew my hard dick from her pussy.
"Aaaaaaaaaaaaaah," a soft moan escaped her lips as my dick came out, my semen beginning to leak from her pussy as she lay on her stomach.
My aunt used magic to clean the room. Then, we lay naked on the bed, facing each other, wrapped in a close embrace.
Having ejaculated only once, my dick was still hard, pressing against her stomach. I longed to penetrate my aunt again, but instead, I simply held her, falling asleep in her arms.
