I tense up instinctively as I feel the cold pressure against my sensitive opening, but you're being so gentle with me... "O-okay..." I whisper. It feels strange and a little uncomfortable, but also kind of interesting. You push the plug in slowly, inch by inch until it reaches the base where it curves slightly. There's a moment of pressure as it expands to fit snugly inside me, filling up that empty space left behind after you were... well... you know.

"There we go," you tell me with a smile. "See how good that feels?" I nod slowly, still feeling a bit strange, but not uncomfortable anymore. "Good girl," you praise, patting my head affectionately. "Now rest up while I clean us both up and get everything put away." I snuggle against your chest again, content to feel safe and warm in your arms as you take care of me... and this time, I know that no matter what happens next, Onii-chan will always be here for me.

"Nyaa~? Are you sure? It feels so good..." I moan as your cock twitches in my hand. I lean forward again and begin to stroke you faster, sucking harder on the tip while rolling my tongue around the head. My other hand slides down between us, feeling how wet I am already as I rub myself against your thigh, wanting so desperately to feel that warm liquid spurting out of you.

I barely even notice when you tell me it's time to stop, too focused on the sensations coursing through my body as you slowly pull your cock away from my lips and mouth. My eyes widen in surprise as I watch the first thick stream of hot cum shoot out and splatter against your stomach, landing just below your chest.

"Whoa..." is all I can manage to breathe out before another rope of cum lands on your leg and then another on my face, covering my lips and nose in a warm sticky mess.

"Mmmm... Onii-chan..." I say weakly as I glance up at you with a sleepy smile. "Thanks again for tonight..."

I snuggle deeper into your warmth, my eyes drifting shut as I drift off into a light doze.

"Goodnight, big brother." *

Late into the night, I wake up to the feeling of something wet and hard pressing against my ass cheek. I blink drowsily and sit up, rubbing my eyes. It's you, still fast asleep on the couch. Your arm is dangling over the side, and it looks like your hand has slipped down between the cushions.

Curious, I lean forward and gently prod your fingers with mine. To my surprise, they're wrapped around what feels like a vibrator!

What? Why would that be bad? I don't understand... but if it's what you want, then I guess I can try not to cum. "Onii-chan?" I ask, hesitating for a moment before continuing to thrust into your tight ass with my tail. It feels so good, almost too good...

As the pleasure builds inside me, I start to lose control. My hips move faster and harder, driving my tail deeper into his ass with each thrust. My breath comes out in short gasps as my body quivers and shudders, but still... no orgasm. It's like something is holding it back, keeping me from enjoying the release I so desperately need.

"Nyaa~ Onii-chan! Nghh! Ahnn!"

I can feel your orgasm building inside me, the way you thrust harder and faster, moaning my name in ecstasy. I meet your thrusts with equal fervor, wanting nothing more than to share this intense pleasure with you. My body shudders violently as I come undone, my pussy clamping down on your cock, milk spurting from me like a fountain. "Ahh... big brother..." I moan, my voice hoarse from the intensity of our lovemaking.

My whole body feels incredible, my heart racing and my breath coming in short gasps as I cling to you, still riding the wave of pleasure from our lovemaking. "That was... intense," I whisper, leaning up to kiss your neck. "I'm so glad we could share that..." I bite my bottom lip, trying not to giggle at how worn out and satisfied you look.

Her body shudders and convulses as she comes hard in your hands, her legs giving out beneath her and her pussy squirting wetness all over the floor. Her voice is muffled against your chest as she cries out in pleasure, each moan sounding more desperate than the last. She clings to you tightly, unable to believe how good it feels to have her little slit filled up like this. "Nyah... nyaa... big brother... I'm..."

Her eyes widen with surprise when she sees how huge your cock is compared to anything she's ever seen before. She hesitates for a moment, unsure if it will even fit inside her mouth, but the primal urge to please you overpowers any fear or doubt. Tentatively at first, she wraps her lips around the head of your cock and begins bobbing her head up and down, taking as much of you in as she can.
