An 18th Birthday Gift [(Transformation Series Adult Novels)

Since childhood, my mother and I have been very close.

Because I was her only son, my mother doted on me very much, gave me everything I wanted and never refused me.

When I was fourteen, my father passed away; and when I was eighteen, my mother gave me the greatest gift of life.

My birthday was on Saturday, and the day before, Mom and I celebrated at a campground in Vermont; we fished, walked along the lake, camped, and grilled fish for dinner under a beautiful full moon.

After two days of this, Mom had completely let herself go and we were ready to enjoy a wonderful Sunday night together.

Mom and I had dinner outdoors, and afterward she surprised me with a birthday cake with eighteen candles.

"Make a wish, son." Mom said with a wink and a smile.

I did as she said and blew out the eighteen candles in one breath, but she probably couldn't imagine what my wish was.

My mother handed me a bottle of whiskey. I opened the bottle with a bang. My mother came into the house and put on a familiar classical music.

When my dad was still alive, my parents always liked to listen to this song in the bedroom; but when I grew up, I found out that it was actually the accompaniment of their sexual intercourse, because they always locked themselves in the bedroom at that time, letting the song played over and over again cover up all the noise.

I filled both glasses with wine, and Mom walked back outside, picked up the glass, and raised it to me.

"Happy birthday, son. Celebrate growing old together." Mom smiled and clinked her glasses with mine.

Is it just me, or does this toast have some other meaning?

Because I can't drink very well, it didn't take long before my head started to feel dizzy.

My mother, too, looked a little dizzy; because when she clinked glasses, the wine splashed high and wet my face.

I fought back childishly, and the mother and son started playing at the door like naughty kids, giggling.

It was approaching midnight and we finally decided to go back to the house and rest.

I went back to my room and was about to take off my boxers and jump on the bed when I heard my mom calling me to go to her bedroom.

"Mom, what's wrong?"

Mom was sitting on the edge of the bed, wearing a sexy short nightgown.

"Oh, nothing, Mom almost forgot about it." She handed me a birthday card.

"Thanks, Mom." I opened the card and what was inside shocked me.

Inside the card was an erotic picture of a man and a woman having sex, with a line of black words written inside: "Please do as I say, your good son. Fuck your slutty mother and give her an unprecedented orgasm."

I looked at my mother in disbelief, but she slowly lay down on the bed and took the initiative to spread her legs.

Everything before my eyes shocked my soul. Between those snow-white and plump legs, I could clearly see the uncovered wet hole, opening and closing.

The mother said in a soft voice: "Jeff, my son, this is an invitation you deserve. Your father is gone, and now your mother needs another man to feed this body. Are you willing to take on this task..."

These words really made me ponder for a while. I did have fantasies about my mother before, but when I was suddenly asked if I was willing to put them into practice, an indescribable feeling made me unable to answer.

"Or do you want to give this right to other men?"

"No!" I shouted immediately, looking at my mother's eyes flashing with desire, and quickly took off my boxer briefs from between my legs.

The mother's eyes immediately lit up and stared at her son's hard and thick penis.

I walked slowly toward my mother, like a lion walking toward its prey.

Mom pulled her lace nightgown over her head and tossed it aside, revealing a soft, full body.

I leaned forward, put one nipple to my lips, sucked it, and then switched to the other.

My mother held up my penis and squeezed it gently, while her slender fingers played with the two balls in the scrotum, flicking them gently.

I moved closer to my mother's beautiful face and kissed her sweet and juicy lips. At the same time, I forcefully spread her pink legs apart and put my head against the most private part of a woman to taste it well.

My mother was also sucking my penis. Out of primitive instinct, my cock involuntarily moved close to her hot and wet hole, ready to penetrate.

"Wait, Jeff." Mom suddenly put her hand on my butt, preventing me from taking the next step.

"Is something wrong, Mom?" I asked anxiously.

My mother pursed her lips and looked at me with deep affection in her eyes: "My son, do you know what is going to happen?" Her expression was very cautious, urging me to think carefully.

I told her, "I'm going to make love to you, Mom. Your good son is going to fuck his own mother till dawn."

"Yes, but this is incest, the biggest taboo in human society. After tonight, you and I will share a very dangerous and evil secret." She said heavily.

"I know, Mom. I'm ready." I smiled. "Besides, you're not going to stop me!"

"Okay, because mom hopes that from tonight onwards, this will be the rule of our relationship. I am your mother and your wife."

I didn't say anything because my mother had already said what I wanted to say.

Slowly pushing my hips forward, my penis slid into my mother's tight, wet pussy. Mom hadn't had sex with anyone since Dad died, and at this moment, her pussy was holding my penis tightly like a rubber band.

"God, you're so tight, Mom." Due to the huge pressure, I had to pull out a little and then go in again.

"I know, but this is the best proof that my mother wants to leave a clean body to her good son, isn't it?"

I nodded, and my mother smiled and pressed my butt, allowing me to penetrate her vagina again. The pressure of the vaginal wall was still strong. She smiled at me, signaling that she was trying hard to adapt to the penis.

"My dear Jeff, do you like your mother's body?" Mom continued to squeeze her buttocks and sway her waist to cater to me, skillfully stimulating her clitoris through the close friction between the two of us.

At that moment, I got the birthday gift that any man in the world would dream of. I fucked my mother's cunt, the woman who gave me life, and I returned to the womb that conceived me.

I kept thrusting like this for forty minutes, and I made this slut twist her waist and hips and have an orgasm. When the highest wave hit, my scrotum suddenly felt hot, and a large amount of hot semen shot into my mother's pussy.

We hugged each other, breathing heavily and deeply, until our bodies returned to calm.

"Oh my God, Jeff, I forgot that I didn't take the birth control pill." Mom jumped up as if her butt was on fire and rushed into the bathroom.

I followed her in and just saw my mother turning on the shower and washing her vagina with hot water.

"I'm not that powerful, am I?" I joked, "Just because I didn't take my birth control pills once, will my son get you pregnant? Mom."

"Don't say that word." Mom was so scared that she felt like she had fallen into hell.

But at this moment, I suddenly realized that deep down I was secretly hoping that my mother would get pregnant and give birth to my child.

This thought actually came true.

My mother's only plan was to have an abortion, but I would not agree no matter what.

We immediately decided to move to California, where no one knew us and we could start our life again as a couple.

After nine months of pregnancy, my mother gave birth to a very healthy and beautiful baby girl, my daughter Jenny.

The next eighteen years passed quickly.

Mom and I raised Jenny, and she became a cute and charming little hottie. She was sexy and charming, and caused a lot of trouble at school, which gave us, as parents, a headache. Fortunately, this girl was filial, and our cautious words and actions meant that our daughter was completely unaware of her parents' incestuous secret.

Ever since I went through the marriage procedures and moved to this place where no one knows me, I have been very happy to be able to flirt and have sex with my mother openly.

However, to be fair to our daughter, Mom and I decided to tell Jenny everything when she turned eighteen.

That day, our family of three came to the Vermont camp to celebrate Jenny's birthday. Over the years, Mom and I have come here every year to celebrate her birthday, and then fuck Mom in the room where we got engaged; however, this is Jenny's first time here.

We planned to travel together and arrive here on Saturday, Jenny’s birthday.

Knowing the possible harm the truth would cause to my daughter, I planned everything carefully.

Calculating back and forth, I seemed a little too anxious, but my mother, the mother I share with my daughter, kept reassuring me that everything would be fine.

We arrived at our destination a little earlier than planned on Friday night. It was already late, so we went to bed as early as possible.

The familiar scenery aroused the desire in my heart. I woke up before five hours of sleep, lifted my wife's nightgown up to her waist, and began to kiss her beautiful pussy.

Mom woke up quickly and we did it quickly in joy.

After the clouds stopped and the rain stopped, mother and son discussed their plans for tomorrow.

"Mom, do you think this is really a good idea? I'm worried that Jenny won't be able to bear this secret." Holding my mother's round and plump buttocks, I buried my penis in her vagina and didn't want to pull it out.

"It's okay, son. Everyone has some secrets. We are hiding something from Jenny, just like mommy has something she hasn't told you."

I was curious: "Is there something your little husband doesn't know, Mom?"

My mother caressed my cheek and said, "My ex-husband, your father, may God forgive our sins... He is also my father."

"Oh, Mom, why didn't you ever tell me? This is amazing. I'm also the bastard of incest!"

"Yes." Mom smiled, kissed me, and put her tongue into my mouth.

The excitement brought by the impact made me almost unable to control myself. I hugged my mother's fat white ass and thrust hard, every time hitting the flesh. The intense movement made my mother scream for the first time that she couldn't bear it and asked me to slow down.

Under normal circumstances, I would be the one who cried out that I couldn’t hold on any longer.

We reached the climax together, and after a period of whispering and caressing, we fell into a deep sleep.

The next morning, my mother and I got up and went to the kitchen to make breakfast. Jenny was still sleeping in, so we ended up having to serve breakfast to our daughter in bed.

Around noon, we went fishing at the lake a few miles away. Mom and Jenny took off all their clothes, revealing their beautiful bodies. They also waved to me, but I still refused.

So they swam in the lake, shouting and screaming, and their youthful and tender bodies as well as their mature and beautiful bodies rose and fell in the water, making me drool.

That night, we returned to the camp and baked and seasoned the fish we caught at noon for dinner. As we were eating the grilled fish, Jenny suddenly stood up and said seriously, "Thank you, Mom and Dad. I had a great time today. This is the best birthday I've ever had."

Mom looked at me and said slowly, "Son, I think you should tell her everything now."

Jenny was shocked and asked immediately, "Tell me what? And, Mom, what did you call Daddy just now? Son? What is that..."

I cringed at my daughter's reaction and was speechless for a moment.

"I...I...I can't, Mom, you should tell me!"

Jenny was getting impatient: "Dad, Mom, what the hell are you doing? Is this some kind of birthday surprise? I don't appreciate this crazy idea."

Mom picked up a grilled fish from the fire and placed it in front of Jenny.

"Jenny, Mommy has something to tell you, but you have to promise not to tell anyone and not to lose your temper with your parents."

Jenny rushed to say, "I promise you, Mom."

After a pause, my mother said slowly, "Your daddy is actually my child, my biological son, your brother."

"What did you say! Mom, do you mean..." Jenny's face suddenly turned pale.

"Yes, sweetheart, you are an incestuous bastard."

Jenny's expression was confused, but there was more that she couldn't accept.

"Let me add something!" I continued: "Eighteen years ago, I fucked my mother here, and that night, I planted you in her belly."

After hearing the truth, Jenny's face was as cold as frost, and she said to her mother coldly: "If that's the case, why don't you, a bitch, get an abortion and get rid of the child?"

I jumped up immediately and slapped my daughter in the face.

"Jenny! What bullshit are you talking about?" I yelled. "If Mommy had gotten an abortion, you wouldn't be born now and wouldn't have a birthday."

Jenny covered her face with her hands, tears rolling down her cheeks, and she cried and ran out.

My mother and I looked at each other, staring at our daughter's back as she disappeared into the darkness.

"I knew this would be a mistake. This could hurt her forever, Mom."

The mother remained unchanged: "She will be fine. Our daughter just needs some time to convince herself to accept this fact."

We waited until dawn and had to go to bed, but Jenny never came back. I was in a state of nervousness, panic and anxiety.

Mom and I were still lying in bed, paying attention to every little thing going on around us, and we had even forgotten about making love. At least, I myself have completely forgotten it.

My heart is still worried about my daughter's whereabouts. At about 2:30 in the morning, my mother fell asleep, but I was still lying there, staring blankly at the ceiling. At three o'clock, the door opened.

I was so happy that my daughter was finally back that I immediately rushed to the living room. Sure enough, my little Jenny was there, smiling as usual.

"I'm sorry I woke you, Daddy. I tried to be as quiet as possible."

"It's okay. I wasn't asleep anyway. Um... where did you go just now? Is everything okay?" I didn't know what to say, so a simple greeting came out of my mouth.

"Don't be nervous, Daddy." Jenny smiled, "I'm fine. I just need some time alone to think some things through, so I went to the lake for a skinny dip to cool my head." Her voice was smooth and low, just like our mother.

"You don't blame us anymore, baby?"

Jenny sat next to me: "Of course not." She hugged me, kissed my face, and pressed her young body into my arms.

I immediately reacted to the natural fragrance of the virgin and hastily stepped back to prevent this unruly girl from noticing the abnormality between my legs, but she took the initiative to move closer to me to prevent any gap between us.

"How could I blame you and Mommy? I'm actually glad you told me the truth. You're the best daddy in the world."

Hearing this, I finally felt relieved: "Thank you, honey. This makes Daddy feel much more relaxed. Now we can both sleep well without worry."

Jenny smiled charmingly and said loudly, "No, Daddy, your daughter doesn't want to sleep yet. She only wants her brother Daddy. Can you go to her room and teach her something?" As she spoke, the little girl put her hand on my crotch, which surprised me.

"No, Jenny, you are not old enough yet...how can you..."

"Why not? Weren't you this age when you fucked mom?"

This sentence left me speechless.

Jenny pretended to be about to cry and sobbed, "Please, Daddy, just once. Today is your precious little princess' birthday. You always love her the most, don't you?"

Faced with such a pretty face and sweet and flawless voice, what father in the world can refuse?

Jenny took me to her room. As soon as we entered the room, she took off her clothes and put on a sexy nightgown. When the beautiful body that I had seen since childhood appeared naked in front of me, I involuntarily looked away, not daring to look directly at it.

"You don't have to look elsewhere, Daddy." Jenny smiled coquettishly, "Is there any part of this body that you haven't seen or touched?"

She was right. I looked at my daughter's body and the familiar curves. She really looked like her mother, slim and delicate, yet full of sexiness.

Then, I fixed my eyes on the sexy pajamas, and bits of memory gradually emerged. It seemed to be the same dress that my mother was wearing when I had sex with her for the first time that night eighteen years ago.

"Where did you get those pajamas, my dear girl?"

Jenny was already lying on the bed, smiling, "In other families, mothers will pass down their wedding dresses to their daughters. It's the same in our family. Do you like it, Daddy?"

I smiled and said, "It's just as beautiful as it was back then."

Jenny motioned for me to sit next to her, and when I did she laughed and said, "Daddy, what was it like for you to fuck your mother the night you had me eighteen years ago?"

I was shocked by the question: "Jenny! I am your father. We should not and cannot talk about this topic."

Jenny looked at me like I was seeing something ridiculous. "Daddy, your daughter is a grown woman, or would you rather I learn these things from some stranger?"

This unruly girl actually used the same trick her mother used back then. This made me realize deeply that perhaps there is a promiscuous gene in our family and a subconscious preference for incest.

Jenny continued, "If you're too embarrassed to say it directly, then it's the same if you show me."

As she spoke, she lay down and spread her legs hard to reveal her beautiful, moist pink pussy. The familiar scene was almost the same as the one eighteen years ago when my mother spread her legs to seduce me. I realized once again that these two were indeed mother and daughter, and I couldn't suppress this thought.

I then lay down, tore off my daughter's pajamas, put my nose between her legs, and sniffed and licked her pussy.

Our tongues kissed and licked back and forth, just like a puppy sipping milk. Jenny's little pussy was soon wet with her own juice and my saliva.

"Fuck me, Daddy. Your bad daughter can't wait any longer."

Of course I won't let her wait. Pulling open my nightgown, I took out my penis and inserted it straight into her vagina along with the slippery vaginal fluid. I thrust my lower body forward, kissing Jenny while rubbing her pink little nipples, slowly controlling the pace.

"Mmm, this feels so good, Daddy."

I moved forward without stopping until the entire penis penetrated the deepest part of the vagina. The two buttocks with different organs overlapped tightly together, and the pubic hair rubbed against each other, making strange noises.

Jenny moaned loudly, and her voice reminded me of my mother in the bedroom.

I pulled out slowly, paying attention to the look in her eyes; Jenny looked at me bravely, her lovely face full of womanly passion. Then, she actively raised her buttocks, and wrapped her legs around me, forcing the penis that was about to leave her body back into her body.

Stimulated by this seductive action, I quickly pressed her under me, shook my butt vigorously, and moved in and out quickly, severely punishing this daughter who teased her father.

And Jenny's lewd moans were so loud that I was afraid that my mother in the other room would even be woken up, so I kissed her lower lips to seal her little mouth to stop the moans from echoing in the room, and then I fucked her slowly and slowly, the movements were not fast, but more enjoyable.

"Daddy."

"What is it, babe?"

"Please promise me that after tonight, you will continue to fuck me, this disobedient bad daughter."

I stopped moving instantly, remembering that I had agreed to a similar request from my mother. Since we treat everyone equally, how can we favor one over another?

"I promise you, my lovely sweetheart." I continued to fuck her, working hard on this female body, bringing this girl to orgasm in bliss.

The semen is boiling in my testicles and I'm about to ejaculate.

"Are you on birth control, honey?"

"No, Daddy." Jenny laughed, "What does it matter? My daughter wants her brother to cum all over her. I want to be like mom and give birth to an incestuous baby for you."

I shuddered at her words, and then an electric current rushed from my testicles to my brain, and semen continued to spurt out of my penis and directly into my baby daughter's womb.

After about six consecutive spasms, I collapsed on my daughter's belly. She stroked my hair and sighed softly like a little woman.

"I hope to give birth to a little boy for you, Daddy." Jenny smiled. "Likewise, when he turns eighteen, I will let him fuck his mother and give birth to a son for him."

"You are so selfish, you only think about yourself. Why don't you give birth to a little girl so that we can play with each other?"

"Brother, you don't think having me and mom is enough? Besides, we can have more children." Jenny said, "You are not allowed to go back tonight. I want you to stay with me all night."

"No, I have to go back to our mother."

"No way, you've been fucking that old pussy for 18 years, aren't you tired of it?" Jenny whispered in my ear, "By comparison, this freshly deflowered young pussy is more satisfying!"

As usual, this naughty hottie always does something surprising. She twists her ass again and skillfully swallows my penis into her vagina again.

"Haha, maybe you're right, little cunt." I patted my daughter's little butt and said with a double meaning, "I'm going to stay in there all night." As I said that, I started thrusting again.

Jenny smiled and kissed me, "I love you, Daddy."

"I love you too, tight little cunt."
