"Then, sister… what if I drink it? Will it satisfy my hunger?"
My sister's eyes stretched wide at my audacious suggestion, as though she couldn't believe the words she had just heard.
I moved a step closer, bringing my head toward her left, untouched nipple, close enough to see the delicate, raised goosebumps that lined the pale skin of her areola.
I felt my sister's breathing accelerate, as though she could feel a charged, electric tingling sensation spreading through her body.
My sister hesitated, struggling to speak. "I... I don't know, Brother. No one in the village has ever tried anything like that, so it is completely unknown if it can satisfy a man."
My sister's voice was trembling and husky, and I could swear her breathing quickened into shallow pants as she spoke.
Was she already aroused and anticipating?
"Then, sister, let me be the first one to prove the truth," I declared.
"Besides," I paused, then said in a deep, calm voice, letting the intensity show, "I'm incredibly, desperately hungry."
My sister bit down hard on her lower lip, her eyes wide with internal conflict, then placed the baby gently beside her.
"Alright, Brother. Come and taste it," she whispered. "If it isn't nice, you have my word, it's alright to spit it out."
I grinned wickedly at her consent.
"Of course, sister, your brother will just have a little taste."
I noticed my sister looking at me with confusion, and I quickly wiped the smirk from my face before she could question my abnormal behavior.
Then, reaching forward, I bent low toward her fair, exquisitely tender, pink nipple and gently brought my lips to meet her skin.
The moment my lips made contact with her nipple, it was as though my sister had been struck by a powerful electrical current.
Her whole body trembled violently as she let out a sharp, involuntary gasp that deepened into a soft moan.
'Why am I feeling this strange sensation? I was just feeding the baby and felt nothing... then why?'
My sister's thoughts were a whirlwind of confusion as she watched my tongue trace slow, wet, spiral movements around her taut nipple before my mouth wrapped fully and expertly around it.
I sucked slowly and deliberately, and a warm, thick, incredibly sweet liquid flooded my mouth…
The warm fluid was incredibly sweet and tasted like a mix of honey and sweet milk. I sucked harder, pulling the nipple deeper into my mouth. The warm sensation instantly traveled to my stomach. It was refreshing, and I could feel my hunger melting away as the thick liquid filled me.
sister let out a loud gasp and gripped the rough wooden bed behind her. Her fingers tightened, digging into the wood. Her body began to quiver as she tried to suppress a moan from escaping her throat. Her face was flushed crimson, and her breathing was coming out in short, shallow gasps.
I pulled back slightly, my mouth still moist with the warm fluid. I lifted my head and stared into her eyes. Her eyes were half-lidded, filled with a mix of surprise, confusion, and raw arousal. The deep crimson blush on her cheeks had spread to her chest and neck.
"sister, are you alright?" I asked, feigning concern and innocence.
Her voice was shaky and breathy. "I... I don't know, Brother. I just felt... a strange tingling sensation, and I... I don't know what it is."
I grinned internally. It seemed that this world's inhabitants were unaware of the powerful sexual stimulation that breastfeeding could provide to a woman, especially one who was already aroused. I could clearly see the lust hidden beneath her confusion.
"Don't worry, sister. Maybe you're just hungry too," I said, before lowering my head once more.
This time, I was rougher with my movements. I didn't stop to ask any questions. I latched my mouth onto her taut, pink nipple and sucked hard, trying to pull the liquid out quickly. The sweet fluid rushed into my mouth, and I gulped it down.
sister's grip on the bed tightened further. She let out a high-pitched moan this time, unable to suppress it. Her eyes rolled back for a moment, and her head slammed back onto the rough wood.
"Ohh!" she cried out, her voice a mixture of pleasure and pain.
I continued to suck, my tongue swirling around the nipple, exploring the soft texture of her full, tender breast. I could feel her heart beating rapidly beneath her chest, the pulse quickening with every hungry suck.
After what felt like an eternity, I finally released her nipple. It was slick and wet with my saliva. The faint scent of her warm body and the sweet milk filled my nostrils.
I pulled back and glanced at the system message again.

I felt a slight jolt of energy course through my body. I had expected the rewards, but the bonus skill was an unexpected surprise.
I looked at sister, and a new layer of glowing text appeared above her head:
[Target: sister (Sister)]
[Arousal Level: 95%]

I blinked, taking in the information. The sheer shock of her 95% arousal level left me momentarily speechless.
sister slowly regained her composure, her chest heaving as she fought to steady her breathing. She looked at me, her gaze tender and intense.
"Brother, did it satisfy you?" she whispered, her voice still hoarse from the moans she had suppressed.
I nodded, swallowing the last of the sweet fluid. "Yes, sister, it was incredibly delicious. It satisfied my hunger completely."
Her face softened into a relief-filled smile. "I'm glad, Brother. You must have been truly hungry to taste something like that."
I gave her a knowing look. "I was. But I might get hungry again soon."
