Sister-in-law who doesn't wear underwear (family incest adult novel)

My sister-in-law's husband died shortly after she got married, so she has been living in my house for a long time. Due to work, she is often away from home during the day. Once I came back from a business trip and instead of going to work, I stayed at home and surfed the Internet. I thought no one was at home, so I browsed adult websites.

"Great! You are watching pornographic websites!" Suddenly my sister-in-law rushed in. It turned out that she was taking a nap and got up to go to the bathroom.

"You...I..." I was speechless for a moment. I saw my sister-in-law wearing a flesh-colored silk suspender nightgown and no bra. Her two nipples were clearly visible. My little brother, who had been eager for a long time, suddenly became erect. "I didn't..."

"You still say no? Look at yourself...are you ugly?" She actually pointed at my little brother.

I had long been coveting her beauty and hot body. I pulled her into my arms and said, "Little girl, don't be shy. Let me show you how I can teach you a lesson!" Touching her silk suspender nightgown aroused my desire even more. My hard little brother pressed against her plump, round buttocks, and one arm pressed tightly against her large and elastic breasts.

"Why am I not shy?" She struggled symbolically in my arms. I couldn't tell whether her butt was struggling to get away from my little brother or pushing hard.

"Look at you, you're not even wearing any underwear... Are you trying to seduce me, your brother-in-law?"

"Nonsense! Why am I not wearing anything?" I knew she was not wearing a bra, but a thong. However, I deliberately stroked her plump, round buttocks and said, "What are you wearing? Why can't I feel it?" I breathed into her ear like a kiss, which made my sister-in-law very confused. I pushed her down on the bed and said, "Let me see if you are wearing anything."

When I lifted her pajamas, I saw a pair of sexy T-shaped panties, which made my eyes pop out. A thin white, transparent pair of panties was tightly stuck in the snow-white crotch, forming a beautiful scene. The narrow cloth could not cover the entire vulva. The left labia was slightly exposed, and the pubic hair on both sides could not be covered, declaring the owner's sexiness. My sister-in-law was lying on the bed with her buttocks high. The extremely provocative underwear made me unable to control myself. I lay on my sister-in-law's back, pressing my hard brother against the plump vulva wrapped in the underwear, one hand kneading the velvety smooth and soft skin, and the other hand holding her towering breasts from below. She screamed and rubbed her vagina on my brother's brother, "No...no...brother-in-law..." Her delicate voice prompted me to rub and caress even harder.

I placed my palms under her breasts, with my ten fingers cupping the tips of her nipples. The index and middle fingers of my left and right hands just pinched her nipples which were gradually becoming hard. Sometimes press it down, sometimes grab and pull it up, sometimes shake it left to right, and sometimes knead it like dough.

Finally, he pinched her nipples between his fingers and rubbed them gently. My sister-in-law's face became redder and redder, and her body was no longer twisting so violently, but she was just jumping up and down because of my stimulation. She no longer cried out, but instead let out soft moans and her body softened.

"Brother-in-law...I...feel itchy...I can't stand it..." As I rubbed her, her whole body went limp.

"Where does it itch...my sister-in-law?" I moved my hand to her lower body and wanted to take off her lace panties. "No!"

She protested softly. She stretched out a hand to protect her plump and fat vagina, and suddenly grabbed my huge erect cock, "It's so big and hard!" She actually squeezed my mace. I took the opportunity to hold her white and tender small hand to prevent her from separating from my brother. She stroked it obediently, making my mace even swell, as if it was about to burst.

I pulled her skirt up to her waist, revealing her snow-white and tender legs, and carefully aimed the tip of the mace at her soft garden.

"No!" She shook her head.

Slowly but firmly, I pushed the mace upwards.

"Well, you...you..." Although she was weak all over, she was still trying her best to dodge upwards.

My huge glans pushed open her thin labia lips through her thin lace panties and began to scrape her juicy vaginal walls, gradually going deeper. She was completely powerless and lost the ability to dodge. The stimulation of being filled with the cock made her numb and tremble. Her whole body was trembling, even the inside of her vagina was trembling. Gradually taking control of her internal organs.

"Hehe, look, my underwear is wet."

"No." She panted and her lower body trembled as I rubbed her. I reached out and took her clitoris between my fingers and began to rub it.

"Ah! Don't..." The intense stimulation made her whole body tremble. "Brother-in-law, please don't do that... ah! Ah... I can't stand it... ah... ah!"

My sister-in-law was trembling all over, twisting her body uncontrollably, and her vaginal fluid was flowing out. She burst into sobs and collapsed on the bed, not daring to move. I turned her over, "No...don't...ah...don't..." Her voice became weaker and weaker, but I kissed her lips. She closed her lips tightly in resistance, but I kept trying to push them open with my tongue. As my fingers twisted, her vaginal fluid began to flow out, and her lips relaxed, so I slipped my tongue into her mouth.

“Hmm… Hmm… Hmm… Sizzle… Sizzle… Hmm…”

She gave up resisting and let my tongue stir in her mouth, even sucking on my tongue involuntarily. I kissed her wildly, rubbing her breasts with one hand and fiddling with her little sister with the other. I kept kissing her until she started to twist her legs, twisting her legs back and forth, and clamping my hand tightly together, as if preventing my hand from going deeper, but also as if urging me to go in, and her vaginal fluid kept flowing out, wetting her pubic hair. She pressed the front end of her pubic bone and clitoris against my lower abdomen and rubbed it hard, and the pubic symphysis continued to twist in a small range with high intensity. Although the amplitude was not large, the pleasure obtained was very strong. My sister-in-law had given up resistance and began to enjoy it.

"Ah~~~ Brother-in-law~~~ Ah~~~ Brother-in-law~~~ Ah~~~" The sister-in-law relaxed and spread her legs, motioning me to take off the strip.

Since then, my sister-in-law has started not wearing underwear or wearing crotchless underwear or crotchless pantyhose, even if my husband
