Having sex with my girlfriend's sister next to her (family incest adult novel)

My acquaintance with my girlfriend started when she asked me for help. In the days that followed, I found that she was hardworking, kind, and pretty, and that she was the type of woman who loved life. We are in love.

One time, I went to her place and suddenly found a girl taller than my girlfriend and with fair skin sitting quietly on her bed. She was a little nervous about my arrival. I casually called my girlfriend's name: "A Ling"

"My sister is not here. She went to the market to buy vegetables." She stood up and talked to me.

"Oh, hey...please sit down!" I looked at her and leaned casually on the bed.

"You - you are her sister?" I asked in disbelief. The fragrance from her body made me speechless.

"Yes, I'm here to play for a few days." Seeing me staring at her, her face suddenly turned red, and she asked me at a loss: "Are you my sister's boyfriend?"

"Yeah! We're good friends, I guess! Nothing much, I just came here to play." I couldn't help but move a little closer to her.

She has thick eyebrows and big eyes, and her medium-length hair is draped over her shoulders, exuding a charming fragrance. Her breasts are raised high, and they are faintly bouncing, as if she wants to break free from the constraints of the black lace bra and be completely liberated.

"Why are you always looking at me?" She lowered her head as she spoke. Her lips were plump and rosy, and a lively and clever tongue kept rolling inside her white teeth, making people want to use their mouths to control its sliding.

"…"

"Do you know how to play games? I'll teach you."

I thought she would like it even if she had never played it before, so I turned on the computer and waved to her to come over.

"Okay... okay... okay."

She danced over to me and sat down next to me, like a little swallow.

I stood behind her and explained to her aimlessly, but my eyes were looking down from her shoulders. The low-cut, thin pink top could no longer fully control her naughty breasts. Now looking from above, they were almost completely visible, with clear cleavage and hazy areola. Only the nipples the size of small green beans seemed a little inconsistent with the towering breasts. I subconsciously lowered my head, and the lingering body fragrance made me put my hand on her smooth hand: "Let me teach you!"

"Hee...hee...this is really fun."

She called happily, looking up at me from time to time and giving me a happy smile. Her clear and bright eyes smiled so sweetly and innocently.

"How old are you?" I asked softly in her ear. He placed his other hand on her shoulder.

I felt her body tremble, and her entire face and ears turned red.

"I'm 18 now..." She shyly pushed away my hand on her shoulder and turned back to smile at me...

"Your sister is here. How are you going to rest tonight?" I put my arm around Ling's waist and stared at the little sister sitting at the head of the bed.

The little girl looked up at me, and when she saw me looking at her, she lowered her head embarrassedly.

"My sister is still young, she can sleep with us." My girlfriend pushed me away and went to tidy up the clutter on the bed.

"A 1.5-meter bed is going to make you feel crowded, but a couple sleeping on a 1-meter bed needs to leave an extra half of the bed."

"Ha...ha..." I clapped my hands and laughed. Ling knew there was something wrong with my words, so she quickly covered my mouth with her hand to stop me from laughing, and kept hitting me with her other hand.

"Okay... okay, you make the arrangements and I'll listen to you," I was so excited that I almost fainted. I couldn't contain my joy and kissed Ling on the ear.

"Come on, my sister is here."

I glanced at my sister, she was laughing with her hand covering her mouth, I winked at her and said, "Why are you laughing? You will have trouble tonight." I said to myself...

Ling was lying beside me, and my little sister was lying beside Ling. Time passed by minute by minute, but I tossed and turned and couldn't fall asleep. The sound of the clock on the table became clearer and clearer. It was obvious that my girlfriend lying in my arms was sleeping soundly.

I pulled my hand out and let my girlfriend lie under my arm. Naturally, my fingers touched her soft hair. I fiddled with it a few times. She moved slightly and adjusted her sleeping position. This slight movement allowed my hand to touch her cheek.

"Is she still not asleep?"... I began to feel my heartbeat quickening. The clear, thumping... thumping sound mixed with excitement and nervousness made my hands tremble.

I boldly stroked her cheek, and could feel her rapid breathing, her plump lips trembling slightly, she swallowed gently, and her hot lips began to crack, I knew she was not asleep yet...

In the dim light of the desk lamp, I saw that she had her eyes closed, her long eyelashes flickering gently, and there were tiny beads of faintly glowing sweat on her small nose. Her sexy lips opened and closed under the touch of my fingers, and a faint blush appeared on her tender, hot face.

Through the thin, white suspender pajamas, I can vaguely see her pair of mysterious small nipples. The clear cleavage is like a canyon between two peaks, deep and deep...

Her flat belly rose and fell irregularly, and I could imagine her heart rate speeding up and her blood boiling.

She had been burned by an unknown fire, her hair, which still retained her fragrance, was scattered on the bed, and her curled up legs were tightly crossed together, as if she was fighting against some force, or as if she was intoxicated by the moisture of a rain after a long drought.

Because of her tall figure, the short and ill-fitting pajamas, and the fact that she kept twisting her body while lying on the bed, her entire buttocks were almost exposed. Looking inside along the inner thighs, one could already see her black lace panties. The materials used in the panties had been calculated again and again by unscrupulous businessmen, and the poor panties were almost unable to fulfil their due responsibilities. The plump inner thighs were sexy and charming, out of reach and yet close at hand.

At first glance, it looks like a long mountain range with undulating peaks and valleys, or like a Viennese statue that is full of vitality and changes.

I didn't want her to pretend to sleep to accept my touch, so I pinched her tender little face hard, and she moaned: "Hmm"...

She opened her almond-shaped eyes and glared at me, then twisted my arm hard with her hand. Although it hurt, I was very excited because her twist was telling me that she was not asleep and accepted my caress...
