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.
