My name is Sato Takahasi, and my mother, Shiori Takahashi, and I have been living together in a house outside of the village of Miyogi, Japan for all of my life. The spring I turned 19, I found a magic plant called the oppahana. The village elder explained that I could dry it and serve it in tea to myself and one other person to made radical sexual changes to the body! I've always been in love with my mother, so of course I served the tea to both her and me. It's now early fall, and we've been fucking endlessly since out last session. If any of the changes get out of hand, I can pray to the shrine god of our village, the one who gifted the oppahana to one man every generation, and reverse anything that grew too much!
We had big, BIG plans for the fall. First, I need to explain a few things. I didn't want to have to sneak into town to pray to our shrine god again, so I asked the village elder if he had a shrine to her at his home. "I've always been just a short walk away from the shrine," he said, "so I've never had to make one in my own home. If you do, though, and show it proper respect with offerings, it should work." The people in town always offered food when they went to pray to the shrine, a duty I had neglected since I found the oppahana. And I had been needing to pray a lot at the shrine the past few months!
It seems that whenever my mom returns home, if I'm still out in the garden or in town on an errand, my mother will always brew a pot of oppahana tea and drink the whole thing for herself! Usually, as soon as she comes home, we spend the rest of the day fucking; I guess she just can't wait on those days I'm absent! I always come back inside to find her, usually in the kitchen, masturbating without even stopping once I return, moaning my name, her breasts grown to ridiculous proportions. She destroyed the wall to my room once in one of these absentee sessions! I didn't mind the changes to her at all, but I had to go back into town late at night and pray to the shrine god each time this happened, which was becoming a drag.
So I came up with an idea, while I was repairing all of the damage we caused the house (the stains would be there forever, though). We had an amazing harvest from our garden this summer, enough to last us into the next spring; I bet our cum from our last big session helped it all grow. But we didn't need it at all! My mom and I sustained ourselves solely on each other's cum. I don't know how it works, but every drop of our cum is like some amazing revitalizing elixir for the other. All we need to do to not go hungry is make each other cum! So, we would be able to sell all of our produce in town during the big fall festival, for a really cheap price. We can then use all the leftover money to build a shrine for our home!
My idea for the shrine at home was this: a big room on a huge stone tile, just a bit smaller than our whole house, still on our land, but just a bit further away from the village than our home was. Carefully polished wooden walls, sealed tight between each plank and the floor. A tight door, and at the opposite end of the room, the shrine itself. The roof would be slanted, and on small stilts from the tops of the walls, so that cum would be able to escape from the top.
I woke up the morning of the harvest festival to an amazing sight. My mom was already awake, and was shoving her face down my cock, practicing her deep-throating. I always woke up with my cock hard, and usually orgasmed at least once while I was asleep, from the wild sex dreams I was always having. My mom was usually asleep still when I woke up, so I just poked her with my cock until she was ready to take care of my erection. Other times, though, especially if my dreams were really crazy, I would just start fucking my mom while she was still sleeping! That was a sure way to make her wake with a start, but she never minded.
I began to cum, and my mom tried to shove herself as far down my cock as she could, about to where my pubes would be. We both trimmed our pubes, now; it was a much cleaner experience. She started to gag, brought herself back up, and I shot the rest of my cum all over her face. My cock was the length of my forearm, still pretty skinny, and I came enough to halfway fill the pot I used to keep in my room and cum into and empty every month. My mom looked like she had drank two cups of oppahana; her breasts were just a perfect fit for my hand, but they overflowed hers, and her ass was nice and soft, great to grab while we fucked. Her hair was usually in a complicated bun behind her head, since it hung down to the floor when she stood, and I asked her not to cut it. Long hair is the best! Her face was perfect, her skin was smooth and usually glistened with sweat or cum, and her big brown eyes were mesmerizing.
We started fucking, as we did every morning. My cock was always a tight fit for her, and tears usually gathered in her eyes from the mix of intense pleasure and pain. She loved every minute of it though, and was always using her dirty mouth to encourage me. "Oh, fuck, Sato, you're HUGE, so big, so tight, FUCK, I can't take this, oh my god, fuckfuckfuck, I'm gonna cum!" The first time she came every morning, I would pull out and drink her girlcum directly, and today was no different.
I usually needed to cum twice to make my cock soft, sometimes three or even four times. In the mornings, even if my cock got soft after sex, it would quickly harden as I watch my mom stumble over to the closet to use the bathroom and get changed, out of breath, with our mixed juices running down her legs. Then, before she could get dressed, I would fuck her again. She had agreed to help me whenever I get hard when we first started our activities together, and she still kept that promise. After that session, I would go to my room and get dressed, while she recovered.
This morning, though, after my cock softened the first time, my mom sat in front of me, legs crossed, cum spreading across the floor between her legs. She reached out her hand and began to rub my penis. "Come on, get hard again! I'm really excited for today, if we build the shrine, we'll have our own fuckhouse! Just think about you and me, filling the room with our cum, until it overflows and the yard is covered in cum!" She moved her other hand to her snatch and started fingering herself, and I needed nerves of steel for this, but my cock stayed soft.
"Sorry, mom, but today's the festival. We can't just sit here and fuck all day! We'll have plenty of time for that when we build the shrine." I stood up, leaving my mom on the floor, pouting and still masturbating. I got dressed, and went into the living room, where I had brought all the harvest. I finished packing it all up into sacks, and started moving them to the cart we had outside. I had to listen to my mother cum again, and resist the urge to pop a boner and run in there to fuck her. Once I had moved all of the food onto the cart, it was mid-morning; the festival began right at the middle of the day. I had time to go back inside and mess around a bit with my mom. The thought of seeing my mom, still lying on the floor pleasuring herself, made me nearly rip my pants with my erection!
But before I could go inside, I tested the cart, to see if I could lift it and push it into town. No, it was too heavy! I could barely lift the stilts off the ground, and I couldn't even push it hard enough to move it! I dropped it, slumped, and went back inside. My mother was halfway into her kimono, but had stopped dressing for a bit to masturbate again. The inside was gonna be stained and smelly with cum for a long time. She looked up and saw my defeated face. "Aw, what's wrong h-ahh!" she must've flicked something sensitive, since she interrupted herself to moan a bit. "ahem, what's wrong, honey?"
"The cart, it's too heavy for me to push! We could go get a cart horse from town, maybe, but whoever brought it over here would smell all the sex." It's true; as soon as you entered our property, now, you could begin to smell the reek of sweat, sperm, and passionate fucking. "I guess I'll just bring the food by going back and forth a few times."
"No wait, I've got an idea!" she pulled off her kimono and ran over to my room, leaving a few spots of her cum to mark the way. She took the oppahana out of my closet. "This makes you stronger, right? All you need to do is drink enough to be able to push the cart!"
"And what will I do with my cock, display it to everyone in town?"
"No, silly, just let me take care of it, and when it's soft, we'll both leave! You can stuff it in your pants, and you'll be behind the cart the whole day, anyway. Nobody will see it, so long as you don't get hard!" It could work. It would be risky, but as long as I kept my mind focused on the sales, I thought I could do it.
"Alright, I'll brew a pot. I'll drink a cup and then cum, and if I can push the cart then, I'll stop."
"Oh, I finally get to watch my baby grow!" She gave me a big hug, slid my pants down, and sat on my cock with her arms around my neck, giving me kisses on the face. It was a rare moment for me to shoot out precum with my cock this small, but this was one of those times.
I brewed the tea, took a cup and drank. My mom jerked me off, and watched as I came all over her and my cock began to grow. It now reached from about my elbow to the start of my fingers. "Wow, my baby boy is growing into a big man!" She licked off the rest of the cum that dripped out of my cockhead, and I drank a second cup and came a second time before I went to see if I could push the cart. Lifting it was almost easy, now, and I could push it forward a bit, but not too far before I became exhausted.
I came back inside. "I need some more of your juice, mom, I'm really tired."
"Sure thing, babe." She sat on the floor and opened her legs, and I began to eat her pussy, slupring up all the cum that came out. I really wanted to stay there and keep going until she came, but I needed to get to the market. I drank a third cup, and my mom tried to give me a blowjob, but she could only fit my cock head in her mouth. She contented herself with licking up and down the shaft, sometimes squeezing it between her huge tits. I came again; now my cock was approaching the upper half of my chest. "Wow," my mom said, gazing at my huge dick. "It's so big, I can't fit it in my mouth anymore!" She began to masturbate, and I went outside to test my strength.
Now I could push the cart! I would need to take a few breaks, but it wouldn't take long, now, to get the cart into town. I came back inside, and said, "Mom! I can push the cart now! Let's get my cock soft, then we can go into town and begin to sell!" When I came back to the kitchen, my mom was still playing with her pussy, and had one of her breasts in her hand, squeezing her nipple tightly and twisting it. The cup I had drank from was next to her, too. She was just about to cum when I guessed that she had drank some of the oppahana tea! I stood there and jerked off, watching her cum.
Her breasts surged forward, stretching and growing firm, her hand still on her nipple. She got so big she almost couldn't reach it anymore! There was a big pool of cum on the ground in front of her that continued to spread. I was able to see her grow a bit taller, and since she was still in the position she had been in when I was eating her out, I saw her grow a bit higher, too, as her ass became a bit more prominent. While she was still in the throes of her orgasm, I began to cum, shooting all over her face and tits.
As I was cumming, I asked her, "Did you drink two cups of the tea?"
She came down from her orgasm high, and gave me a deliciously sexy look. "Yes, I had two. I couldn't help it, watching you grow was too much for me! I've got a kimono I made to fit me for this size, so I'll wear it." She started to eat the cum I was covering her with. When I finished my orgasm, and she finished her eating, she stood up and grabbed my dick. Her tits were just under twice the size of her head, now, and amazingly firm as always. "Let's see what we can do about this big, throbbing, cock, hmm?"
