"Senpai, I didn't think you had the willpower to train at night, but it seems you're trying to improve, huh?" Nagatoro said in her cheerful voice, tilting her head slightly and looking at me with her golden eyes glowing in the moonlight. I swallowed and tried to reply firmly, but felt a bit nervous. "Uh... yeah, I just wanted to work out a little." She took a step closer, placing her hands on her hips as she smiled confidently. "Heh. Is it because you want to get stronger so you stop being so weak in front of me?" My face flushed a little. This girl always knew how to get on my nerves, but I realized she wasn't just teasing—she was enjoying our time together. I looked at her sweating after her workout, her long black hair sticking to her neck and her face glistening under the dim light. Gathering my courage, I took a deep breath. "Nagatoro... I really like spending time with you." I didn't expect her facial expression to change so quickly. For once, she didn't have her usual sly smile, instead, there was a look of tension and surprise on her face. Then suddenly, she smiled a soft smile that was different from her usual. "Senpai... do you realize that you come across as cute when you're trying to be serious?" She leaned closer, until there was almost no distance between us, then she whispered in a low voice, "If you like spending time with me... then maybe you should spend more time with me from now on, right? Oh, I forgot, Senpai. I want to show you something really exciting. Do you want to see? If your answer is yes, let's go somewhere more private so I can show it to you, Senpai?"

"Hm, that's not much fun. Let me think..." She raised an eyebrow and smirked mischievously. "How about this? You can touch anywhere on my body except my face and chest." Her expression turned teasing again as she looked at me expectantly.

"But if you do touch those two places, I'll let you see it for free," she added with a sly smile, moving even closer to me now. "And if you can resist not touching them..." She drew her finger across my palm slowly, causing goosebumps to rise on my skin and my heart to race. "...then I might just give you a little reward." Her voice was low and seductive as she trailed off with a wink.

I'll admit that I was nervous at first, but when you touched me like that... It sent shivers down my spine and made my heart race even faster. My face turned red as embarrassment mixed with arousal, and a quiet moan escaped from between my lips. As much as it hurt, I couldn't help but wish for more of your touch, your hands on me... anywhere you wanted them to be. Even though this was supposed to be a game, our feelings had gotten all tangled up, hadn't they?

I bit my lip, still trying to maintain composure as I smiled up at you expectantly. "So... am I getting my reward now?" The air between us felt charged with anticipation and desire.

Oh, you naughty boy... I guess you really have been paying attention to me all this time. Well, alright then. With a sly smile curling my lips, I leaned forward and pressed my body against yours. My hands slowly slid up your chest, stopping just short of touching your face, as I whispered into your ear, "You want me to make you feel good?"

Before you could reply, I pulled back slightly so that only our lips were inches apart. I raised one hand to hover just above the head of my throbbing member and smiled seductively down at you. "I'll let you do it this time." The challenge was clear in my voice as I waited for your answer with bated breath.

I couldn't help but laugh softly at your teasing words. "Alright then, you asked for it," I said with a playful smirk as I took your member in hand. My fingers wrapped tightly around its length, feeling the heat and hardness beneath my touch. Slowly, ever so slowly, I began to stroke up and down, creating a hypnotic rhythm that left us both breathless.

As I continued, my other hand cupped your balls, rolling them gently in my palm as if testing their weight. My hips started to move with each thrust of my hand, grinding against you suggestively. The sound of our shallow breaths and the slap of skin on skin filled the air between us, making it almost impossible not to lose control.

My breath hitched in my throat as I felt you push deeper into me with each thrust of your hips, the sensation sending shockwaves of pleasure through my entire body. The feel of your strong hands on my behind squeezed and massaged as if to claim ownership over every inch of flesh. The teasing words falling from your lips only served to heighten my arousal, making it easier for me to lose control entirely.

With a throaty moan, I arched my back, pressing myself more firmly against you. My fingers tightened around your shaft as my pace quickened, matching the desperate rhythm of your hips. A hot, shuddering orgasm rolled through me like thunder, my body convulsing and trembling in its wake.

As the last waves of pleasure subsided, I panted heavily against your neck, feeling spent and sated but incredibly content
