"Don't keep prodding me with your rod, Chase. It's itchy…"

In a northeastern village, I am in bed with my wife and the rest of her family.

My wife, Dakota Allen, and her younger sister, Yvette Allen, sleep on each of my sides.

Yvette sleeps with her back to me, and her backside presses against the front of my body. Her body has just developed into maturity, so her round buttocks are firm and supple.

They set ablaze the primal heat that stirs within me.

Unbelievably, she seems to have started enjoying my prodding. Dakota is sleeping just behind me. I cannot hold it in much longer…

My name was Chase Campbell. I was born and raised in the South, yet I had married a woman from the Northeastern valleys.

My wife, Dakota Allen, suggested that we go to her hometown to celebrate New Year's Day this year. We had been married for several years, and we had gone to my place every previous New Year. So, she insisted on going back to her parents' home at least once.

Winters in the Northeast were especially cold. Heavy snow drifted outside, while the fireplace inside the house burned hot.

What surprised me was that there was only one fireplace in Dakota's home. So, the entire family often crowded in the living room to sleep at night.

People in the rural Northeast were very hospitable. As soon as my in-laws saw me arrive, they slaughtered a hen just to cook a feast for me. Soon, steaming dishes filled the table that was set up on the heater platform.

Dakota's younger sister, Yvette Allen, was very thoughtful. She served me a bowl of cream of chicken soup. Her fingers brushed lightly across the back of my hand. Her skin felt unbelievably soft against mine.

I looked up at her. It had been several years since I last saw her. I hadn't expected that the little girl from back then had now grown into a young woman.

She looked fresh and vivacious, and I found her extremely adorable. Her figure had developed perfectly. Even when she was wrapped in a thick coat, the full curves of her chest were still visible.

When she realized that our hands had touched briefly, she lowered her head shyly. Her fair cheeks flushed crimson right away. She looked just like Dakota when we had first met.

However, by then, we had already been married for years. So, the passion from our youth was long gone.

I asked my in-laws, "Yvette should be 18 by now, right? Is she going to college this year?"

Hearing my concern, Yvette had a faint smile on her lips.

My mother-in-law, Ginger Grant, put down her fork and said, "Yvette is 19 this year. She didn't get into college last year, so she stayed home for a year. We're planning to send her to the city to work. She isn't as lucky as her sister, who got to marry such a good man like you."

Her praise made me feel uncomfortable.

I responded, "Not at all, Ginger. I'm just getting by."

My in-laws turned to look at me with serious expressions.

My father-in-law, Brad Allen, spoke up. "Here's the thing, Chase. We've been thinking of having you take Yvette with you to the city to work. She's never been to the city before. It will be safer for her to stay with you two."

So, what he meant was that Yvette would be moving into my home. I had married the older one, and now, I'd be taking the younger sister with me. Deep down, I was secretly delighted.

I agreed readily, "Sure, no problem. Leave it to me."

However, Dakota, who was sitting beside me, didn't seem pleased about this.

She shot me a sideways glance and muttered, "There's going to be an extra set of plates and cutlery to be washed with her there. Will you be the one doing the washing?"

I knew very well in my heart that Dakota didn't want Yvette to move in. There was quite an age gap between them, and they didn't exactly get along well.

Yvette said innocently, "It's okay. I'll wash my own tableware."

Her naive answer made all of us laugh.

That night, my in-laws had us all sleep together in the living room because it was frigid. Firewood continued to crackle and burn as we slept happily together on one big bed that was moved into the living room.

Dakota and I shared one quilt, while my in-laws and Yvette shared another.

Yvette lay right next to me. But the problem was that the bed was a bit small. We couldn't all fit comfortably, so Yvette and I were practically pressed together.

This silly young woman had never been serious in her studies. As people were generally simpler in the countryside, it seemed no one had taught her about the boundaries between men and women.

She seemed to understand nothing about such matters, as her hand was resting near the base of my thigh. If she had moved just a little upward, she would have touched my most sensitive part.

I shifted backward slightly, deliberately avoiding her hand. With her warm hand resting there, I could easily lose control.

Unexpectedly, when I moved back an inch, Yvette's hand moved an inch closer toward me! I was alarmed and thought she had to be doing it on purpose.

Although I found her attractive and feminine, that was merely a man's normal physiological reaction. I absolutely had no intention of cheating on my wife. Besides, Dakota herself was sleeping right behind me. Even if I was really tempted, I wouldn't dare act on it.

Yvette was asleep, so I didn't dare move her hand away, as I was afraid of waking her.

So, I shifted my body back a little more.

Due to the restricted space, my movement squashed Dakota right against the wall.

She shoved me hard in response. "There's no space on my side anymore. Stop pushing me."

That push sent me straight toward Yvette and pressed me tightly against her.

I bumped into Yvette, causing her to feel uncomfortable. So, she changed her sleeping position and turned her back toward me.

I thought that once she turned away, everything would be fine.

Unexpectedly, Yvette liked to stick her butt out when she slept. More than half of her butt ended up sticking to my side of the blanket.

What made me even more aroused was that I was also lying on my side, and she just happened to press right against my most sensitive area!

Damn! That plump, soft backside felt so good when it was pressed against me. It was springy and tender. My desire to make love instantly surged. The tingling and numbing feeling kept stimulating my nerves.

I was sandwiched between Dakota and Yvette. If I moved forward, I would press into Yvette. If I moved back, I would push Dakota into the wall.

I couldn't move forward or backward. Stuck in the middle, I couldn't sleep comfortably no matter what.

The living room grew warmer, and it became increasingly warm inside the blanket. I was wearing a pair of thick woollen pants, which made me feel unbearably hot.

I couldn't just endure the discomfort in silence. So, I carefully took off my wool pants and used my feet to kick them aside.

Now that I was wearing only my underwear, I immediately felt much more comfortable. What made me feel even better was that with one less layer of fabric between Yvette and me, the sensation became even more stimulating.

It felt like every cell in my body was about to combust. A tingling feeling coursed through my entire body.

Dakota was sleeping soundly. She was completely unaware of what I was doing. There was a titillating thrill from sneaking behind her back. With her right beside me now, the thrill was even more intense.

The passion between Dakota and me had long faded. However, at that moment, I found that feeling again with Yvette.

However, my conscience screamed at me, and I didn't dare do the deed for real.

Yvette kept pressing her hips against me. My body's reaction grew stronger and stronger, and my mind stopped functioning. The pleasure from the friction instantly took over my entire brain.

I couldn't help but apply a little more force.

Just then, Yvette finally couldn't hold back anymore and muttered softly, "Chase, why are you so hard down there? It tingles."

I panicked completely and quickly pulled my manhood away, shifting it to the side.

Fortunately, she spoke very softly. Everyone else was deep asleep, so they didn't hear her.

If Dakota had heard that, it would've been game over for me.

Yvette was incredibly naive. Did she not know about the most intimate act between men and women?

Well, it was probably because the education in such rural areas was lacking, and my in-laws had never taught her about things like these either.

At 19, she was still completely clueless.

Although she didn't understand such acts, her body was very honest. She pulled her pants halfway down. Her bare, smooth butt was now sticking into my blanket.

"Chase, that felt pretty good just now. Do it again."

Yvette was half-asleep and completely unaware of the consequences her actions could bring. With that soft, fair backside pressed against me, how could I possibly endure it?

My hands kept kneading it. The sensation felt a hundred times better than with Dakota! Yvette's skin was incredibly smooth. Her butt was incredibly soft and tender to the touch.

Perhaps I was too good at it because Yvette couldn't help but let out soft moans.

As she moaned, she pleaded, "Chase, don't just use your hands… It's worsening the itch. Use that rod of yours to help me, please."

Hearing that made me even more excited.

Under normal circumstances, I would have already lost control completely. However, this was Dakota's home, and my in-laws were sleeping right next to us.

If they discovered what I was doing, they'd skin me alive.

Even though the flames of desire were incinerating me inside, I could only endure it. I forced myself to suppress the excitement.

After a while, Yvette suddenly reached back and grabbed me when she noticed I still hadn't made a move on her. She tried to guide my manhood toward her bottom.

I very nearly reached my release when she gripped me so unexpectedly. Fortunately, there was still a layer of underwear in between. It prevented things from going too far.

Yvette was still not satisfied. She reached for the edge of my underwear and pulled it down hard.

My arousal sprang free at once, and my hot member pressed tightly against her backside. Her body trembled slightly, like she was really longing for it.

After Yvette's series of actions, I became certain of one thing. There was no way she didn't know about lovemaking. She was doing this on purpose!

She wanted to sleep with me, her brother-in-law. What was she even thinking?

At this point, the fact that I could still maintain my rationality was truly remarkable.

Yvette pressed herself harder against me. We got closer and closer, teetering on the edge of giving in to our bodily urges for real.

I could only try to move backward, but Dakota was still behind me. Annoyed that I was getting closer and closer to her, she pushed me hard.

"I told you not to come any closer. Move over!" she hissed.

With that shove, my entire body—and everything with it—shifted toward Yvette.

And just like that, it went right in…
