How Long Can I Hold Out When My Stepsister and Stepmother Seduce Me Every Day?

Chapter 1: The Daily Life That Starts to Collapse

My name is Lin Yu, twenty-two years old. I just graduated from university and am staying home to prepare for graduate school entrance exams.

Dad remarried two years ago. My stepmother, Su Qing, is thirty-eight. She takes excellent care of her body—large breasts, slim waist, skin so fair it looks like it could be pinched and water would come out. My stepsister, Su Nian, is one year older than me. She just returned from overseas, has an open personality, and loves wearing revealing clothes.

At first I could still keep my distance.

Until this month.

Su Qing always walks into the kitchen in the morning wearing only a loose silk robe with nothing underneath. When she bends over to get the milk, the neckline gapes open and those heavy, full breasts almost spill out, the areolas faintly visible. She deliberately leans her body against me, softly bumping my arm with her pliable chest, then says in that soft, slightly hoarse voice:

“Yu-yu, want Mommy to warm some milk for you? You’ve gotten so thin lately…”

Su Nian is even worse.

She likes wearing ultra-short home shorts paired with a tight little tank top, the two points on her chest clearly sticking out. Every time she passes my room she deliberately pushes the door open, leans against the frame, puts both hands behind her head and stretches, fully displaying a pair of breasts just as exaggerated as her mother’s.

“Little brother~ Big sister’s shoulders are so sore, help me massage them, okay?”

One time she sat straight down on my lap, her butt gently grinding, warm breath brushing against my ear:

“Why are you hard? Does little brother have dirty thoughts about big sister?”

I tried my hardest to endure.

But every day, every hour, every moment, they kept wearing down my reason in all sorts of ways.

Chapter 2: The Accident in the Bathroom

What truly pushed me to the edge was one night in the bathroom.

I finished showering and realized I had forgotten to bring a change of clothes. Su Qing was standing in the hallway. When she saw me wearing only a towel, her eyes lit up for a moment.

“Mommy will get it for you.”

She walked into my room but took a long time to come out. When she did, she had already loosened the belt of her robe. She was completely naked underneath—snow-white skin and deep cleavage fully on display. She handed me the clothes, but her fingers “accidentally” brushed the towel at my waist.

The towel fell.

I froze. She didn’t look away immediately either.

That already half-erect thing was completely exposed to my stepmother’s eyes. Su Qing stared for two seconds, then slowly licked her lips and spoke in a voice low as a murmur:

“…It’s even bigger than I imagined.”

She didn’t help pick up the towel. Instead she used the tip of her foot to kick it aside, took a step forward, and gently pressed those soft, heavy breasts against my chest.

“Yu-yu, want Mommy to help you… take care of it?”

At that moment Su Nian also appeared.

She leaned against the wall, arms crossed, a smile at the corner of her mouth: “Mommy’s so sly, trying to keep him all to herself?”

The two women sandwiched me from left and right. Su Qing’s hand was already wrapped around me, stroking slowly up and down; Su Nian pressed against me from behind, her breasts against my back, one hand reaching around to pinch my nipples.

“Little brother has been holding it in for a long time, right?” Su Nian breathed into my ear. “Tonight let the two of us help you together, okay?”

I gritted my teeth and said, “No… this is incest…”

Su Qing only gently kissed my Adam’s apple: “But you’re this hard. Your body is much more honest than your mouth.”

Chapter 3: The First Time I Lost Ground

That night I ultimately didn’t completely give in. I only let them use their hands and breasts to make me cum once.

Semen sprayed across Su Qing’s huge breasts. She actually smiled, scraped some up with her finger, licked it off, then looked at me and said:

“Tomorrow we continue.”

From that day on, the scale completely went out of control.

In the morning Su Qing would slip into the covers while I was still asleep, take me into her warm mouth until I was fully hard, then leave as if nothing had happened, leaving behind only the words “Breakfast is ready.”

Su Nian preferred to straddle my lap while I was studying, wearing only a loose T-shirt with nothing underneath. She would deliberately grind her wet entrance against me through my pants while whispering in my ear:

“If little brother just nods, big sister will let you inside right now…”

I refused every day.

But the sound of my refusals grew quieter and quieter, while my body’s reactions grew stronger and stronger.

One time I truly almost couldn’t hold back. I grabbed Su Nian’s waist and tried to push her down, but she suddenly stopped, smiled, and pinched my cheek:

“Not yet. Hold on a little longer, little brother. When you really can’t take it anymore, then the three of us can play properly.”

Chapter 4: The Night of Collapse

Finally, on a Friday night, I broke.

That day Su Qing and Su Nian somehow went into sync.

Su Qing first pushed me down onto the sofa, straddled me herself, and rubbed her soaked entrance back and forth against the head of my cock without ever letting me inside. While grinding she untied her robe, and those huge breasts slapped directly against my face.

“Want to go in?” she asked.

I nodded hoarsely.

She shook her head: “Not yet. Let Nian join first.”

Su Nian hugged me from behind, both hands reaching around to rub my chest while pressing her breasts against my back. She whispered in my ear:

“Little brother, we already agreed today… if you dare cum outside, you’ll be punished by sleeping on the floor tonight.”

The two of them worked together. Su Qing finally sank down slowly, taking me all the way to the root. Her hole was hot and tight, the inner walls instantly clamping down. Su Nian moved around to the front, offered a nipple to my mouth, and ordered me to suck.

I completely stopped thinking.

That night they took turns riding me, had me take them from behind, sandwiched my cock between their breasts until I came, and later simply let me cum inside. When Su Qing was creampied she let out a long, satisfied moan. Su Nian laughed and said “Big sister’s turn,” then sat down and continued.

By the end I had almost nothing left to shoot, yet the two of them still weren’t satisfied and kept extracting more from me in every possible way.

When dawn came I lay on the messy sheets, covered in sweat and various marks. Su Qing and Su Nian leaned against me on either side, fingers still lazily tracing over my abs.

Su Qing whispered in my ear:

“Now… how much longer can you hold out?”

I could no longer speak.

I could only close my eyes and feel their hands moving downward once again.

It turned out that from the very beginning, I had never truly been holding out.

I had only been pretending I could still endure.
