Lines We Dare Not Cross
"Alright, let's do that, son." Mom accepted my suggestion to combine kissing, caressing, eating her out, and mutual masturbation. On paper, it was the most practical arrangement, so she really had no choice but to agree.
"Then I'll start right away."
"...Yeah. Let's do it."
After announcing my intent, I grabbed her shoulders and laid her down on the soft grass. Then I pulled my cock out of my panties and brought it to her mouth.
"Mom. Suck it now."
Mom didn't answer. She simply lifted her head from where she lay and took her son's cock into her mouth. While she sucked me, I shifted my body until we were in a 69 position. From there, I grabbed the waistband of her panties and tugged them aside. Her alluring pussy, which never failed to captivate me, came into view. I pressed my fingers against it and rubbed lightly. Mom twitched, and the suction on my cock grew stronger.
I was thrilled by her reaction. This is it. This is what I wanted!
Having my cock sucked while I touched and licked her pussy drove me wild with excitement. I savored the thrill coursing through my shaft and stimulated her more roughly. Mom sucked my cock while her son ate her out. Our actions grew feverish, almost competitive.
"Mom, I'm about to cum."
When I warned her, she sucked harder. The intense stimulation from her mouth forced me to climax faster than I wanted. Spurt, spurt, spurt, spurt. Thick ropes of semen erupted, all of it shooting straight into Mom's mouth.
"Hah... hah... hah... hah."
The mutual oral session ended. Mom lay on the grass, catching her breath. Even after that powerful orgasm, I still wasn't satisfied. I pressed my still-hard cock toward her and said, "Mom, this doesn't seem as efficient as I thought."
Sixty-nining made it difficult to kiss or drink her milk. I had known this would happen, but I pretended otherwise and reported the result.
"You're right. Should we go back to how we were doing it before, even if it's slower?"
"No. There's another way."
"There is? What is it?"
"It's hard to explain with words, so I'll just show you."
"...Okay."
After saying I'd show her, I spread Mom's legs and positioned myself between them. Then I brought my rock-hard cock right up to her pussy. Mom's eyes widened in shock as her son's shaft approached her most intimate place.
"S-Son! W-What are you doing right now?"
Startled, Mom reached down and grabbed my cock to stop me. Still unable to push forward, I answered, "I'm not putting it in. Just watch calmly, Mom."
"You're not putting it in, right?"
"Of course not. Did you really think I would? Don't overreact and move your hand."
I kept my tone casual as I asked her to let go. Mom seemed swept up by my confidence and released me. With my erection hovering just in front of her pussy, I said, "As long as I don't put it in, it's fine. I'm right, aren't I?"
"Y-Yeah... as long as you don't put it in..."
By this point, we had already sucked each other's genitals inside the Tower. Aside from actual penetration, we'd done everything. Mom knew that too, so she agreed that not inserting it was acceptable.
"Mom, I swear I won't put it in. Trust your son, okay?"
"...Alright."
I emphasized that she should trust me, and Mom, carried along by the situation, consented. Hearing her answer, I brought my cock to her pussy. Finally, my glans touched her soft folds. Zap.
"Hnnngh!"
Mom gasped, her eyes flying wide open. I felt an unbelievable jolt of pleasure but forced myself to hold back. If I hadn't just cum earlier, I probably would've blown my load right there.
This was the first time my cock had ever touched Mom's pussy. If I hadn't climaxed moments ago, I might have finished instantly. The sensation was that intense.
"Nothing's happening, so relax, Mom."
I was just as excited and tense, but I reassured her while gently moving my hips. Slide. Slide.
"Haaaah..."
My shaft rubbed along the parted lips of her pussy. This feels incredible. It's a crazy kind of joy I can't even put into words!
Rubbing my cock against Mom's pussy brought overwhelming pleasure. Rub. Rub. Rub. I kept grinding against her.
"Hah... hah... Son, d-don't make a mistake... haaah..."
"I'm focused, so don't worry, Mom."
"I'll trust you, son... haaah..."
"Yeah, Mom."
Though I was incredibly aroused and wanted to focus solely on rubbing, I had to keep Mom calm, so I put on a bright expression first. Rub. Rub. Rub. I continued stimulating her pussy.
Mom's properly turned on too. A man's cock was busy teasing her sex. Her mouth hung open, her eyes glazed and unfocused. The sight of her was incredibly erotic and sexy.
I'm already about to cum. The stimulation from her pussy was intense. I felt the urge to ejaculate far sooner than usual.
"Mom, grab my cock with your hand."
"Okay. I will, son."
Mom reached down with both hands and gently wrapped her fingers around my shaft. The moment she held me, I started moving my hips again. Rub. Rub. Rub. It almost felt like I was slipping inside. I thrust more vigorously.
"Cum now, Mom."
"Cum. Go ahead and cum, son."
Spurt, spurt, spurt, spurt, spurt. I came again, this time spraying my load all over Mom's stomach.
"Even on your second time, you came so much."
Mom stared at the semen coating her belly with a mix of admiration and something else. Mom must be frustrated, right? After finishing, I carefully studied her expression. Just as I expected, she looked satisfied yet faintly disappointed. It might have been my imagination, but that was what I saw.
"Mom, I think this method is good. We can still kiss, drink your milk, and stimulate your pussy enough that I can lick up your juices right away. It's the best. Don't you agree?"
Rubbing my cock against her pussy took care of masturbation, while kissing and drinking milk remained possible. Whenever her arousal leaked out, I could simply dip my head and lick it up to regain strength. Theoretically, it was the ideal solution. Mom didn't voice any disagreement.
"Let's keep doing it this way. I think it's the best option."
I pushed for this method. Mom always accepted my opinions inside the Tower without refusal.

"Found it! There's a safe zone over there, Mom!"
"You're right. Thank goodness."
Without relying on the village, Mom and I had wandered busily through the forest, mapping it out. Carefully avoiding the monkey packs, we finally discovered the second safe zone. Unlike the first, there were no monkeys here.
"We'll be able to sleep comfortably tonight."
"Yeah."
The previous night, Mom and I had hidden in the underbrush and slept in silence. It had been uncomfortable and tense; we hadn't rested properly, and fatigue had built up. Today we'd finally get to sleep safely and comfortably. This place was similar to the previous safe zone. Water flowed down one wall, and fruit grew in abundance. I stripped off my robe and panties and took a shower right there. Mom didn't find it strange that I was completely naked.
"You sweated a lot too, Mom. Go ahead and wash up. You'll feel so much better afterward."
Once I finished, I urged Mom to wash as well.
"...Yeah. I-I will."
Mom removed her clothes and began washing. I watched her, still naked myself. Naturally, my cock grew hard. Cute.
Mom knew I was staring at her with an erection. Even so, she didn't turn around, though her face flushed. I found her shy awareness of her son endearing.
Hugging her from behind while she washes would probably be too much, huh?
I wanted to approach her, kiss her, and rub my cock against her pussy, but I doubted she'd appreciate that. As much as I wanted to, I held back. Just watching is already more than enough! Don't get greedy.
I patiently observed every step of her shower. When she finished, Mom finally turned around. Seeing that I was still naked, she spoke up.
"Son, aren't you going to put your clothes back on?"
"What's the big deal? It's just us. It feels nice and cool. You should stay naked too and come over here. It's healthier that way."
We had no towels to dry ourselves. The temperature here was comfortable enough to stay naked, so it was better to remain bare until we dried naturally. Thanks to my confident attitude, Mom eventually came over without putting her clothes back on. We sat side by side, both completely naked.
"Son."
Mom's voice dropped, as if she had something important to say.
"Yeah?"
"Once we pay off your father's debt this time, let's stop climbing the Tower."
"Why are you saying that?"
"Why? We agreed to that when we first left the first floor."
"But we still ended up coming back to the Tower."
"That's true, but... I don't think we should keep climbing."
"Can you tell me why? This place is full of opportunities, after all. I want to hear your reasons properly."
I asked in a challenging tone. It was because I didn't dislike climbing the Tower with Mom.
"It's dangerous. That's the biggest reason. And... what we're doing... this isn't... right. You know that too, don't you?"
