It was deep in the night, and I took a shower and wrapped myself with a bath towel before stepping out of the bathroom.

"Tianming, are you tired from studying? Your sister-in-law is pouring you a glass of milk," I gently knocked on the door and said.

Living in the room next to mine is my husband's younger brother, Li Tianming. He moved in with us since he got into a prestigious high school and had to come to the city to study.

Everything is fine, but there's one thing I am too embarrassed to say.

Tianming doesn't regard me with any shyness in the house, and he strolls around all day only in his tight underpants.

Whenever I catch an unintentional glimpse of that thing underneath him, it seems to be even larger than my husband's, which makes me extremely embarrassed.

"Thank you, sister-in-law." Tianming opens his door, predictably, only in his underpants.

Tianming is tall. He lowers his head to look at me, seemingly staring at my bust. Startled, I hastily pull up my bath towel.

"The exam is coming soon, isn't it?" I asked, feeling awkward.

"Mmm, it's tomorrow."

"Rest early," I said, even though I don’t want to look, that thing still forcefully intrudes my sight.

At night, I am lying in bed, tossing and turning, unable to fall asleep. I wondered how big exactly was that thing under Tianming's underpants?

How could I have such thoughts about my brother-in-law!

Though my husband treats me well, his experiences in a certain aspect are limited and cannot fulfill me, not to mention he's frequently away on business trips.

Feeling somewhat agitated, I twist my body. While feeling a sense of shame, I slowly stretch my hand downwards.

During the night, I was in a drowsy slumber, feeling a pair of arms embracing me.

Half dream, half awake, those hands were playing with my chest, making me feel very comfortable.

In the dream, I felt the sensation, actively responding to it.

"Mmm... Darling..."

It seemed that I felt something hot pressing against my behind, and, unconsciously, I rubbed against it.

"Darling..."

Then, those heated hands explored downwards, tugging at the edge of my underwear.

"Ah!"

I suddenly woke up, rolled over and saw the person next to me. To my surprise, it was Li Tianming!

"Tianming! How... How did you come to my room?"

Tianming seemed very weak, resting his head heavily on me.

"Sister-in-law... My head hurts terribly, so I wanted to find some medicine, and I felt uncomfortable, so I laid down here."

I frowned and laid a hand on his forehead.

"Are you running a fever? Let me get you some medicine."

"No need, sister-in-law. I'll be better after lying down for a bit; you should also lie down again."

"Though I feel it's inappropriate, I have no choice but to lay down since he claimed to be ill.

Tianming hugged my waist, and I trembled slightly, a bit nervous.

Tianming is, after all, my brother-in-law, and given our ages, this really isn't suitable!

"Tianming, don't... don't get so close to your sister-in-law..."

"Sister-in-law, are you afraid I'll pass my cold to you?" he asked.

Upon hearing this, I urgently shook my head, "No, no. Why would your sister-in-law think such a thing?"

Tianming is unpredictable, and I'm frightened to offend him.

He buried his head in the crook of my neck, his breath tickling me all over, something hard and hot pressing against my thigh.

This kid, Tianming, he couldn’t possibly be aroused, could he!

Impossible!

I struggled slightly, "Oh... Tianming, you're gripping too tightly. I...I'm out of breath."

"Sister-in-law, I'm so hot..." he still didn't let go.

"So am I..."

"In that case, sister-in-law, why don't you take off your clothes?" He chuckled, his eyes impishly fastened on my chest.

"What...How could I? Tianming, you're a grown man after all, it's... inappropriate."

Before I had finished speaking, his expression changed immediately.

"Sister-in-law, has my staying at your house caused you lots of troubles? You're getting tired of me, aren't you? Fine, I'll move out if I have to."

As he said this, he let out a chuckle, stood up, and prepared to leave.

I felt a pang of anxiety and quickly shook my head, "That's not what I meant, Sister-in-law just slipped off..."

I really didn't understand what was going through this kid's mind, but since he put it that way, I had no choice but to unfasten the straps of my nightdress and shyly shrink into the blanket.

Tianming hurriedly snuggled up beside me, his big hand firmly holding me and pulling me forcefully into his arms, his hard object was just on my crotch.

I shivered at the sensation, immediately feeling a dampness below, it was like countless bugs were crawling, making me itchy.

What a delightful thing it would be if that thing of Tianming's entered my body.

But while I was indulging in fantasies, Tianming was already reaching down with one hand while holding my waist with the other.

"Ah! Tianming...," I couldn't help myself, as I tightened my legs, trapping his hand, and let out a moan.

He must have realized that I was wet.

I wanted to find a crack in the ground and hide.

"Sis... Sister-in-law," Tianming said slowly. "I... I feel a bit uncomfortable."

So did I.

I turned around, and when his thing left my legs, I felt a sense of emptiness.

Pretending as if nothing had happened, I reached out and touched his forehead. "You're not feverish..."

"It's not here. It's down there." Tianming twisted his body and innocently asked, "Sister-in-law, why is down there so uncomfortable, it feels hot, could it be an allergy?"
