NTR: My Apartment Complex

The scorching-hot and thick semen continued to spurt out, filling every corner of the tight uterine cavity, yet Erin’s hip-riding rhythm showed no signs of stopping. Caught in the vortex of ultimate pleasure, the stimulation from the warm fluid combined with the massive phallus still buried deep inside pushed the teacher’s entire nervous system to the brink of explosion.

Erin’s entire slender body suddenly stiffened. Her eyes opened wide and stared blankly into space, her pupils glazed over with ecstasy, while her chest arched backward to the absolute limit of its curve. She parted her mouth wide, unable to utter a single complete word, only managing broken, agonizingly prolonged moans in vain:

"Aghh... aaaaa... I can’t take any more...!"

At that very moment, her tender vulva contracted with an unprecedentedly violent force, squeezing the veiny fibers of the phallus with a breath-taking grip. From the depths of her body, a large volume of milky-white sexual fluid began erupting in torrents, blending with the earlier semen to form a lewd mixture that overflowed from the cleft and streamed down her thighs.

Her body trembled violently as if struck by lightning, her chest heaving heavily before she collapsed completely against my muscular chest, panting in broken breaths in a state of utter exhaustion and paralysis.

The fierce climax that had just passed left a brief silence in the passion-drenched classroom. I cradled the teacher’s trembling, limp body of exhaustion in my arms, the corners of my lips curling into a smug and provocative smile. Looking at her face, still lingering with a dazed expression, I leisurely offered a suggestion:

"Come on, the battle isn’t over yet. Try rocking your hips gently from side to side."

Erin stared blankly for a beat, completely failing to grasp my intent. Yet, with her consciousness not yet fully recovered from the orgasm, the teacher still instinctively followed my instructions, slowly moving her round buttocks from side to side.

However, after barely a single gentle rock, Erin’s entire body froze, her eyes widening in sheer horror and disbelief. Inside the slimy, semen-filled vaginal cavity, she distinctly felt that the familiar, rigid tactile shape had neither softened nor sagged in the slightest.

The massive phallus inside still stood proud, bulging with interwoven blue veins and maintaining a terrifyingly perfect erection.

The teacher’s face turned pale, shock written plainly across every facial feature as she stammered out through choked, astonished sobs:

"No way... clearly... clearly you already ejaculated... why is your dick still standing this rigidly...?"

Facing the teacher’s extreme panic, I threw my head back and laughed loudly with casual arrogance, my tone carrying absolute triumph:

"Haha, surprised, teacher? This student’s endurance and stamina far surpass anything you can imagine. Now get ready for the next round."

Hearing my confident and ruthless declaration of a second round, Erin’s already pale face grew even more panicked. The teacher hurriedly shook her head back and forth, her tear-filled eyes gazing at me with a pitiful, pleading look as she spoke in a voice hoarse from fatigue:

"Please... spare me... I’m so exhausted, my body can’t take anymore..."

Yet those feeble pleas did not sway my intentions in the least. Instead of replying, I swung my hand down and delivered a sharp, resounding slap against her heaving, voluptuous, round buttocks. A bright red mark instantly stained her smooth white skin, the crisp impact echoing through the cramped space.

I smirked cunningly, lowering my voice to a dominant, husky pitch:

"Spare you? Keep dreaming. This ass was born for me to enjoy."

With that, I used my hand to push her exhausted body to tilt sideways onto the bed. Quicker than lightning, I shifted my position, pressing my entire large, scorching body from behind directly against the teacher’s trembling, high-arching, plump rear.

Knowing full well she had been cornered and completely stripped of any chance to escape, Erin let her arms drop in despair. She slowly turned her head back, looking at me with a helpless, resigned gaze before obediently and automatically planting her hands against the mattress, raising her hips high to surrender herself to the lewd doggy-style posture.

Seeing my prey cooperating voluntarily, my excitement surged even more strongly. I raised my hand and repeatedly patted her bouncing buttocks, feeling the marvelous elasticity beneath my palm and chuckling with amusement at the teacher’s humiliating yet alluring submissive stance.

Gazing at the alluring and helpless doggy-style posture of the female teacher before me, I curled the corners of my lips into a cunning smile, my eyes dropping down to her cleft still dripping with semen and pulsing with a rhythmic beat. I teased with malicious amusement:

"Your pussy must be exhausted after all that, so let’s give it a little rest."

With that, I reached both arms around her waist, using my fingers to grip both sides of Erin’s full buttocks and pulling them wide apart with force. This sudden movement parted her round rear completely, exposing her moist vulva in full view, and right behind it, her tiny, pink anal opening tightly clenched in fear.

Catching sight of the new target, Erin widened her eyes in panic, her entire body jerking violently. She frantically shook her head, reaching out as if to push my hand away while speaking in a panicked, pleading voice:

"Wait... no... that’s the back door... please don’t put your dick in there... agh..."

That warning and feeble resistance could not stop my actions in the least. Without a shred of hesitation, I pressed the large, fluid-dripping glans of the phallus right against the rear entrance, then decisively pressed forward with strength, pushing my hips ahead.

Rustle... squish...

The massive, heavily veined phallus slowly squeezed past the violently contracting sphincter muscles, brutally invading the tight anal cavity. The breathless sensation of tightness, fullness, and restriction instantly enveloped the shaft, making both of us shudder with arousal. The sudden pain combined with the overwhelming sensation of being filled by an oversized object in an unexplored territory made Erin let out a miserable scream, her hands gripping the bedsheets until they turned bruised, her lips pressed tightly together to stifle her shattered moans:

"Aghh... um...!"

I continued applying force, driving straight forward in a single motion until the phallus plunged all the way to the hilt deep inside the back door. That total invasion made Erin’s spine arch like a bow, her reddish-pink tongue lolling out from being unable to bear the pleasure and extreme stretching, her mouth emitting choked, broken moans:

"Aghm... so deep... so tight... no way... that spot... that spot hurts so much..."

Feeling the internal sphincter muscles tightly squeezing every fiber of the phallus, I threw my head back, panting, and began slowly rocking my hips from side to side to savor this wonderful sensation. Leaning down, I pressed close to the teacher’s ear and spoke in a husky, satisfied tone:

"Your back door is really tight, teacher... hugging me this close."

Tortured to the point of panic by the brutal invasion and oversized phallus, Erin’s body trembled violently across the mattress. The teacher bit her lip hard enough to draw blood, her tear-filled eyes turning back to glare at me over her slender shoulder as she spoke in a hoarse voice, filled with resentment and helplessness:

"You... you really are a wicked student... you monster..."

Hearing that feeble and sullen reproach, I let out a low chuckle. Reaching my hands forward to grip her slender, snow-white waist to stabilize her posture, I gently reassured her with a cunning expression:

"Don’t worry so much, teacher. You’ll get used to it slowly... be a good girl, I’ll ride very gently and leisurely so you can slowly enjoy this feeling."

Receiving that provocative reassurance from me, Erin’s body trembled faintly in the helpless doggy-style position. I didn’t rush to thrust rapidly right away, instead keeping my promise by slowly withdrawing the phallus almost to the glans before leisurely pushing it deep back inside.

Each movement unfolded with extreme slowness and leisure, yet precisely because of that, the vicious friction between the veiny surface of the phallus and the delicate mucosal lining became all the more stark. The breathless sensation of tightness and fullness enveloped the rectal cavity. Bending down, I distinctly felt each wave of sphincter muscles inside the teacher’s back door contracting violently, hugging every fiber of the shaft with a warm, crazy suction force.

Even though the pace had been reined in, because this private zone had never been explored before, the sharp pain intertwined with strange pleasure still left Erin unable to suppress herself. Closing her eyes tightly, her hands clawing the bedsheets, she lowered her head and emitted choked, broken moans:

"Ughmm... gently... it hurts so much... it’s too tight there... pull some of it out..."

Hearing that soft plea, my amusement and self-satisfaction surged even higher. I curved my lips into a teasing smirk, pressing close to her ear and casually dropping a provocative remark:

"You know, teacher, technically I’m the one who has exclusively claimed the very first time for both holes on your body. Doesn’t that feel quite honorable?"

Hearing that utterly shameless and deeply joking declaration, Erin’s face instantly flushed bright red with anger and embarrassment. The bottled-up grievance made her whip her head around, glaring at me with daggers in her eyes as she scolded resentfully:

"You... you really are shameless without a shred of decency! You’ve already robbed me of my purity and yet you still dare to open your mouth and say such mocking things...!"
