Since that crazy Friday night when I took Shen Yufei’s virginity, my life felt as if it had been injected with a powerful stimulant.

The once-boring routine of a salaried worker had turned into an exciting countdown game filled with anticipation.

Every day at my desk, I no longer thought about reports and PPTs. Instead, my mind was occupied by the two very different yet equally seductive bodies living next door.

My "Neighbor Mutual Assistance Program" had officially become normalized. The rules were simple and perfect: Wednesdays belonged to Lin Xinrou — the mature, plump mother; Fridays belonged to Shen Yufei — the youthful, firm daughter.

"Brother, I’ve paid this week’s ’tickets’ on time. You have to get me the new DLC for *God of War*."

This was a voice message Shen Shuai sent me on Wednesday afternoon.

The kid’s tone had become increasingly sophisticated, as if we weren’t discussing the rape of his mother and sister, but some ordinary internet café deal.

I tapped on the keyboard, a smile forming at the corner of my mouth, and replied: "Don’t worry, the game was bought long ago. As long as you add enough ’milk’ tonight, it’ll be on your table early tomorrow morning. Remember, Aunt Lin seems a bit more alert lately because of her physical ’discomfort.’ Give her the right dose — not too much, not too little."

"Leave it to me. Don’t you trust my work? I guarantee she’ll sleep so deeply that thunder won’t wake her!"

Putting down the phone, I took a deep breath. Tonight was Lin Xinrou’s night.

At one o’clock in the morning, I opened the Lin family’s door with the spare key, moving with practiced ease. The living room was quiet, with only the faint hum of the refrigerator running. I walked straight to the master bedroom and turned the doorknob.

The room was filled with the unique fragrance of a mature woman, mixed with a faint scent of high-end skincare products.

Lin Xinrou lay on her side on the large double bed, wearing a silk slip nightdress.

The fabric of the nightdress was so thin and pitiful that it could barely contain her proud F-cup breasts.

With her steady breathing, the two masses of snow-white, soft flesh threatened to spill out from the neckline. The deep cleavage looked like a black hole capable of devouring a man’s soul.

"Sister Xinrou, I’m here again," I walked to the bedside and looked down at her mature body, murmuring softly. "I got a little tired of the usual positions last week. Let’s try something new tonight."

I stripped off my clothes, leaving only my underwear, then climbed onto the bed. The unconscious Lin Xinrou was like a docile lamb, completely at my mercy.

I grabbed her shoulders, turned her over, and positioned her face down on the bed. Then I gripped her plump waist and hips with both hands and lifted her up forcefully.

"Mm..." Lin Xinrou let out an unconscious muffled groan. Her soft body slid down slightly.

"Good girl, kneel properly and stick your ass up," I said, pressing my knees against her inner thighs and forcing her legs apart into a standard doggy-style position.

This posture was pure visual ecstasy.

From behind, her wide, plump ass cheeks looked like two ripe peaches, raised high.

Due to gravity, her massive F-cup breasts hung down heavily, pressing against the sheets and squeezing into an astonishing shape.

And the secret garden that was normally hidden between her legs was now fully exposed before my eyes.

In the dense black forest, her pink slit — no longer as tightly closed as before thanks to previous sessions — was slightly parted, exuding a seductive hormonal scent.

"Truly a body made to be fucked from behind," I admired. I pulled off my underwear, letting my iron-hard cock spring out.

I didn’t bother with much foreplay. This body already had a strong memory of my shape and taste.

I simply teased her slit with my fingers a few times, and crystal-clear love juice immediately oozed out, moistening the surrounding soft flesh.

"Sister Xinrou, your body is much more honest than your mouth. Look how wet you already are before I even enter," I smirked, aiming my thick glans at her dripping entrance.

I gripped the soft flesh around her waist with both hands and thrust my hips forward sharply.

*Puff—*

Accompanied by a teeth-grinding wet sound, my entire cock drove straight in, burying itself to the hilt in one thrust.

"Ah!" Lin Xinrou’s body suddenly stiffened. A soft, tone-shifted moan escaped her throat.

Even in deep unconsciousness, the intense stimulation of being instantly filled caused her body to react instinctively.

Her vaginal walls contracted rapidly, wrapping around my cock like warm, wet dough.

"Yes... that’s the feeling! This plump, juicy pussy is incredible!" I growled and began thrusting wildly.

*Pap! Pap! Pap!*

My lower abdomen slammed fiercely against her plump ass cheeks, producing loud, crisp slapping sounds.

With every impact, her two massive ass cheeks rippled violently like jelly, sending out circles of lewd flesh waves.

From this angle, I could also clearly see her enormous breasts hanging down, rubbing and shaking frantically against the sheets in time with my thrusts.

"Sister Xinrou, does it feel good? My cock is much better than your useless ex-husband’s, right?" I taunted her while pounding frantically, verbally humiliating this usually dignified single mother. "Look at your ass — the waves are flying everywhere! Your womb is desperately sucking on my glans!"

Lin Xinrou couldn’t answer. She could only shake weakly on the bed in rhythm with my movements, broken moans spilling from her mouth: "Mmm... Ah... Don’t... It’s so deep..."

Her vagina felt like a bottomless quagmire — warm, wet, and amazingly elastic.

Every pull dragged out large amounts of mucus; every thrust forced the layers of beautiful flesh apart.

"So fucking good... Sister Xinrou, I’m going to cum! I’ll fill you up!"

After nearly half an hour of continuous, intense thrusting, I felt a powerful current rush from the base of my spine to my brain.

I gripped her hip bones tightly, pressed my cock hard against her cervix, and erupted.

Hot semen shot into the depths of her mature womb like a high-pressure hose.

Lin Xinrou’s body convulsed violently. Her vaginal walls contracted frantically, as if greedily milking every last drop from me.

I lay on her back, panting for a while, before slowly pulling out my cock.

A large amount of white turbidity mixed with transparent love juice slowly flowed down her thighs, staining a large lewd patch on the sheets.

"This is just the appetizer, Sister Xinrou," I wiped the sweat from my forehead, turned her over, and laid her flat on the bed.

"Next, let’s try a more ’active’ position."

I lay down beside her, lifted her by the waist, and positioned her so she straddled my hips.

Although she was unconscious and her body was limp like mud, I supported her so she could barely maintain the riding position.

I held my cock, aimed it at her slightly gaping, cum-leaking hole, gripped her waist with both hands, and pulled her down hard.

*Schlick—*

My cock sank fully inside her again. This position allowed extremely deep penetration. I could even feel my glans pushing open her cervical entrance.

"Hngh!" Lin Xinrou’s brows furrowed in pain, her head hanging weakly against my chest.

"Don’t sleep. Move for me," I smiled. I gripped her armpits and began manually moving her body up and down.

*Puff... Puff... Puff...*

In this passive cowgirl position, the most spectacular sight was her massive F-cup breasts.

As I lifted her body, the two heavy, soft mounds bounced and jiggled wildly in the air. Her areolas glowed seductively under the light, like two big white rabbits trying to break free.

"So big... I could play with these tits for the rest of my life and never get tired," I groaned. While enjoying the tight, wet grip around my cock, I reached up and kneaded her enormous breasts roughly, squeezing them into all kinds of lewd shapes.

The sense of conquest — treating this mature, beautiful woman like a living sex doll — made me completely lose myself.

Two days later, on Friday, the target switched once again.
