This Should Suffice
I decided to wrap up the testing after thoroughly analyzing the effects of having sex with Mom. Of course I wanted more, but I didn’t want to come across as a son desperate to fuck his own mother. Maybe I already looked that way, but it was still better to hold back. Mom was the most precious person in the world to me. I always wanted to be a good son to her.
It’s interesting how the healing effect gradually weakens while sleeping.
The six-hour boost to healing and defense lasted longer when I slept, probably because my body’s rhythms slowed down. I got up, made a few cuts to test it, and confirmed that sleeping extended the healing duration by about fifty percent.
“Mom. Let’s head to the upper section of the forest now!”
Once I had a clear grasp of sex’s benefits, I set off with Mom toward the upper forest, where even larger monkeys appeared.
They look similar to the smaller ones, but they must be a different species.
The boundary zone had no small monkeys at all. Their territories were clearly divided by species.
This spot will do.
The entrance to the upper forest was damp and gloomy, but free of immediate threats. I stopped moving and relaxed.
“Mom. Let’s have sex here before we go in.”
“Okay. Let’s do that.”
We were right at the edge of danger, so sex was necessary for safety. I asked naturally, and Mom accepted without hesitation.
“It’s safe here, so let’s do it lying down comfortably, Mom.”
“All right, son.”
Mom lay down on the soft grass.
“Just in case, I won’t take your panties off.”
“Do as you like.”
Warrior Mode was crucial in dangerous places. I wouldn’t remove Mom’s panties, and I had no intention of taking mine off completely either. I spread her legs, hooked my fingers into the side of her panties, and pulled them aside to expose her pussy.
I want to lick it, but I’ll hold back.
I really wanted to bury my tongue in her and suck, but I couldn’t risk needing my strength later. Instead, I rubbed her clit with my fingers.
“Hnnngh…”
Mom grew sensitive quickly, her golden juices spilling out and wetting the area around her slit. I kept stroking her, then brought my cock over and rubbed it against her entrance.
Schlick. Schlick. Schlick.
“Hah… hah…”
“I’m putting it in.”
“G-go ahead.”
Schlick.
I only pushed in halfway.
“Haaah…”
Mom’s pussy welcomed her son’s cock, squeezing it tightly with heat. As always, being inside her felt incredible.
Schlick. Thump.
“Haaahng!”
Once I was fully buried, a memory surfaced—the time Mom had teased me right after our first kiss on the first floor.
Squelch. Squelch. Squelch.
“Hah… hah… hah…”
I moved my hips gently and asked, “Back on the first floor you praised my kissing… remember?”
“Y-yes… I did… hnn…”
“Then why haven’t you ever rated my sex skills?”
“That’s… hah… hah…”
Thump!
“Aaaah!”
“I want to hear it from you.”
Thump! Thump!
“Hngh… hngh…”
“So tell me. Give me an honest evaluation of how good your son is at sex.”
Thump! Thump! Thump!
“Son… hah… hah… you’re just… too big… hnn… so of course you’re good at it… haaah!”
Thump. Thump. Thump. Thump. Thump.
I started thrusting in earnest.
“Sounds like you’re saying I was born good at sex because you gave birth to me. Is that right?”
“Y-yes… that’s right… hnnngh…”
“I see. Mom?”
“What is it?”
“Say it properly. Tell me your son is good at sex. I want a real compliment.”
“That kind of thing is…”
Thump! Thump! Thump! Thump!
I drove into her harder.
“You told me about the kissing. Come on, say it! I really want to hear it.”
Thump! Thump! Thump! Thump!
I kept pounding her while urging her on.
“Son is good at sex… aaaah… he’s definitely a man who can satisfy a woman… hnn… is that enough now?”
“Yeah! I feel more confident. So look forward to it!”
Thump—!!!
“I-I don’t know… haaahng!”
The praise had been forced out of her, but it still felt good. I was the kind of man who wanted to do well. From now on, I would fuck Mom’s pussy with everything I had.
Thump! Thump! Thump!
I thrust with renewed enthusiasm. During it we kissed and I drank her milk. Now we were fully prepared to enter the upper forest. I sped up to finish.
I’m about to come.
Climax was close. I didn’t warn her.
Spurt spurt spurt spurt spurt!
My cum poured out in thick ropes, and Mom’s womb accepted her son’s seed.
Just like I expected, she didn’t say anything.
I knew when her fertile period was because she had told me. She had already informed me, and after so many times of finishing inside, she didn’t comment on it anymore.
“Son, you’re very healthy.”
“Why say that?”
“Why else! Because there’s just so much semen.”
Mom wiped away the cum flowing from her pussy several times. Even I could tell there was a lot.
**
We returned to the upper forest. The heavy air and lack of sunlight made the place feel eerie. Mom and I moved forward cautiously.
Over there.
The scent of monkeys reached my nose. I pointed with my finger to show Mom, then hid behind a tree. Two large monkeys appeared exactly where I had indicated. I immediately crouched in front of Mom. She spread her legs to help, knowing what I was about to do.
Slurp. Slurp.
“Hnn…”
Mom covered her own mouth with her hand. While she did that, I sucked on her pussy and absorbed her juices. Once I had gained strength, I gave Mom a thumbs-up, picked up the wooden spear I had prepared earlier, and approached the monkeys.
Now!
When the distance closed enough, I rushed forward and threw the wooden spear.
Shhhk—
Thud!
My aim was flawless. The spear pierced straight through one monkey’s heart, killing it instantly.
Even big ones can’t do anything if a spear hits them in the heart.
I had worried it might not die, but that had been unnecessary. Relieved, I grabbed another spear.
“Ook! Ook! Ook ook!”
The remaining monkey spotted me and charged with bloodshot eyes. I quickly threw the second spear.
Shhhk—
The large monkey twisted its body and dodged. Figured it would do that. I had already thrown anticipating a dodge. So I swung my axe at the charging monkey instead.
Whoosh—
My axe followed its predicted movement. The monkey leaped into the air, presenting its head.
Thud!
The axe buried itself in the monkey’s skull. The fight was over.
Let’s keep going.
I had killed two in an instant. I tossed the corpses into thick undergrowth where they wouldn’t be found and moved deeper.
I won’t fight monkeys I can see anymore.
Small ones were one thing, but the big ones required real power. I planned to kill them for certain without overextending.
**
Time passed quietly under tension. Night fell before we knew it.
It’s going to be a frightening night.
Mom and I had killed three more monkeys, but we hadn’t found a safe zone by the time darkness arrived. We found a good hiding spot, crawled inside, and lay on the ground. At night we had to stay especially quiet. We whispered to each other in the smallest voices.
“Son. What do you think of this place?”
If we could just find a safe zone, things would get easier. We could lure and kill the monkeys like before. But something felt wrong.
“I think there might not be any safe zones in the upper forest.”
“Why do you think that?”
“The Tower’s difficulty keeps rising. Safe zones that make things convenient for us won’t keep appearing forever. I suspect this is where they stop.”
“Then what… what do we do now?”
Mom’s voice was full of worry. I spread my arms and pulled her into a hug.
“You’ve got me. We’ll just kill them one by one, so don’t worry about anything.”
“I can’t even begin to say how grateful I am to have such a reliable son.”
Mom pressed herself deeper into my embrace.
Ah—this feels good.
Mom trusted and relied on her son. It felt nice that this woman, my only family, seemed to see me as the head of our household.
I will protect Mom with my own hands!
I didn’t want to entrust her safety to anyone else. I swore I would protect her through my own effort and will.
I steeled my resolve, and naturally ended up on top of her. Mom was now pinned beneath me. I looked down at her and leaned in for a kiss.
Slurp. Slurp.
This wasn’t a kiss for immunity. It was just because I wanted to. After kissing her to my heart’s content, I said, “I did that because I wanted to do it with you.”
“…”
Mom stared at me with heated eyes but didn’t say anything. I pushed her bra up, freed her breasts, and took one into my mouth without hesitation.
“Haaah… haaang…”
After sucking on her breasts thoroughly, I spoke again. “I sucked on them because I wanted to, Mom.”
I told her twice. Not for adaptation or power—just because I wanted to.
