A thousand mile journey started with the first step. For Claire, she had been taking meaningful steps. From stopping her habit to inflicting harm upon herself to venture into this place, even if I held her hand, her own will fueled her courage.
Her own will claimed my belief. She was more courageous than she knew. For that reason, I wanted her to realize her own strength. She definitely would enter this dungeon.
My thoughts weren't finished yet, and I barely blinked my eyes once. When I opened them, she presented herself before me. With her body bowed as she grabbed my forearms with her own trembling hands, her teary eyes found relief upon seeing me.
"B-brother, I am glad you are fine."
I pulled her into my embrace, our skin warming each other from the coldness of the dungeon. Letting her listen to my heartbeat, her trembling limbs eased. "Sister. It must be hard for you. You can punish me all you want here. What do you want me to do? Tying myself? Raping me? This naughty little brother is yours to use tonight."
Usually she would look at me excitedly, but her eyes still emitted gratefulness and relief, as if dungeons were the most dangerous things in her mind. After seizing my whole body fully, she tapped her forehead on my chest and rubbed it. "I'm just glad you are alright. Let's just go out. We can still make it."
I looked at her grey head and then at the system screen before me.
[Congratulations! You have completed a quest: Fix Clairemont Eldora's Trauma. Reward: 10.000 AP]
10.000 AP was the most I ever acquired. The last time this many points entered my system pocket, I had to host a grand event. Here, only a single quest granted me that. However, was this alright? I believed her trauma still haunted her. As a good little brother, I wanted her to stand in a dungeon with her head raised high.
As if listening to my wish, a pop-up screen appeared before me.
[Challenge Quest: Conquer the dungeon with Clairemont Eldora. Fee: 10.000 AP. Reward after completion: 100.000 AP. Failure punishment: Claire's trauma is getting stronger. Warning: if you agree, the rating of the dungeon will increase from F to D]
The empire laws allowed initiate awakeners to challenge F to E rated dungeons. Beyond that, the dangers were too immense for those below expert-ranked awakeners.
Increasing the rating of the dungeon seemed to be a suicidal move, especially if your guide had been inactive for years. However, those who jumped into a dragon's lair and came back, they pocketed immense wealth. I sought no material fortune; I sought salvation for her. For that, she needed to fix her own problem by actually trying to do it.
I didn't click accept to the challenge yet. First, she needed some appetizers to enhance her courage. Killing monsters seemed like a good idea, and hey, we were in the weakest dungeon ever, Slime Dungeon. What a good chance.
I patted her head and said, "Sister, this brother wants to try hunting monsters. Will you watch me?"
She looked up at me with a wry expression. "N-not a good idea. Dungeons are dangerous places."
"There are only slimes here, though. Please, Sister. Look, my little brother is also excited for some action." I pointed at my still hard rod. In truth, this mighty falcon had never gone flaccid ever since I entered this place. To show my excitement, my fingers wrapped the shaft and massaged it back and forth.
Her grey eyes reflected my hand in action, and she gulped. "O-okay, but we cannot go too deep, okay?"
I released my grip on the shaft and said, "You are the best. Alright. You can watch me from behind."
As I began my adventure, she followed me close behind. Or rather, she glued herself on me like a koala on a tree. Her arms wrapped my body, and her nipples poked my back.
I wondered if she would let me go if we encountered a monster. My mind couldn't guess it, but I allowed her to stick herself on me for now because she needed it to ease her mind. In fact, my mischievous mind pushed a lewd idea. I grabbed her hands and put them on my dick. Almost instinctively, she stroked it with nimble movements. It felt like a party was happening on my groin.
"Hmmn. It's good. Sister, are you feeling better too?"
"Hmmm..."
She didn't answer my question. However, her hands became more dexterous, a sign that she was getting relaxed. I read the cue and let her enjoy massaging my dick while my eyes wandered around the dungeon structure.
Blue crystal embedded the walls, ceilings, and ground. Their soft light allowed us to see well in this enclosed space. If I had no knowledge about the dungeon, I would think they were precious, but Dungeon Crystals, while a useful resource outside, sold at cheap prices due to their abundance.
Aside from Dungeon Crystals to accompany our adventure, the path ahead was honest without any trick, and I doubted natural traps existed in the beginner dungeon in the first place. So, I could enjoy the sightseeing, while my sister-girlfriend jerked me off.
"Brootheerrr, your endurance is simply astonishing. Cum for me, pleaseee~"
"Hahahaha." I felt flattered when she praised my endurance, and I wanted to repay her effort.
I grabbed her hands and turned around. As she looked at me in astonishment, I pinned her against the wall.
"Brother?"
I cupped her lips before whispering, "I want to make my sister feel good too. Turn around."
"W-we... are we going to do it here in the dungeon?" she asked nervously.
"Why not? I can hear your heart beating wildly, and...." I reached her vagina and grabbed it. The dripping liquid coated my fingers, and I smeared it on her clit. "You are flooding down there. It must be hard to endure. This little brother will perform a filial duty. Turn around, my sister."
For a moment, I saw love-shaped marks in her eyes, but I couldn't confirm as she complied with my request obediently.
I licked my hand and lubed my shaft. Then, like a ram, I penetrated her vagina in one go.
Claire stuck out her tongue and screamed, "AHHHHHHHNNNNNN~~"
