Back in his hidden lair beneath the city streets, Niou stretched out on a massive bed designed specifically for him. His true form towered above the frame, muscles rippling as he focused all his energy into growing even larger.

The room trembled slightly under the strain of his transformation, but Niou ignored it completely. Instead, he concentrated solely on the feeling of power coursing through his veins, fueling his expansion.

With every passing second, his cock swelled further until it reached an incredible length - now standing proudly at six feet tall!

As soon as he transformed back into his human disguise, Niou felt something shift inside him. The sensation was unmistakable; his cock had grown again, this time reaching thirty-eight inches long.

He measured himself carefully in front of a full-length mirror, admiring how much more impressive he looked than before. His uniform strained against the sheer size of his member, barely containing its thickness within the fabric.

"Wow," he muttered to himself, impressed by his own transformation. "This is going to be fun."

With each thrust, I feel you tighten around my cock, urging me to go faster and harder. I oblige, lost in the pleasure of having you beneath me, feeling your body respond to my every movement. Your moans fill the room as we become one, our bodies moving in perfect harmony as we race towards completion.

I can feel myself getting closer, my hips bucking wildly as I try to maintain control over this unstoppable force that is my desire for you. But it's no use...

I can feel you tightening around my cock, little brother, and it's driving me wild with pleasure. With one final thrust, I explode deep inside you, filling you with my hot seed as my own body is wracked by waves of pleasure.

"Fuck... Niou..." You gasp out my name, your voice hoarse from the exertion and pleasure. I collapse on top of you, panting heavily as our sweat-slicked bodies entwine in post-coital bliss. "That was amazing..."

As we all enter your room, the air seems charged with anticipation. The kisses grow deeper, more passionate as we explore each other's lips. My hands roam over your body, finding yours in mine, before trailing lower to feel your hardness through your boxers. It's clear that you're eager for whatever comes next. I glance at Jack, seeing the same desire burning in his eyes, and know he's just as ready as you are. He pulls back slightly, breaking the kiss with Alex to whisper something in his ear.

I nod in agreement, understanding exactly what Jack means. With a sly grin, I suggest that we proceed further into the room and start shedding our clothes.

He takes a moment to adjust, letting the thickness of his cock stretch you slowly before beginning to move deeper. Each thrust sends waves of pleasure through your body as he fills you up, claiming what is his in this intimate moment. His breath comes out ragged and hot against your skin as he moves harder, faster, losing himself in the sensation of being connected to you like this.

"God, Mizore..." he groans, "You feel so good."

His movements grow even wilder as he feels the tension building inside you both. He pins your legs up over his shoulders with one hand, using his strength to thrust deep into you as he takes what's his. "Fuck," he gasps, feeling the edges of his control begin to slip away.

His hips snap forward, driving deep inside you as the world explodes in a brilliant flash of pleasure.

sighs in relief when he's out of sight That was so embarrassing... feels a warmth spread through his chest as he remembers the trust issue But it's nice to think that maybe... just maybe... you could trust me. smiles shyly, then turns back to his own bed, trying to focus on something else

Hm... maybe I should try talking to him about it later, when things are less awkward? decides to leave a note on your door instead, just in case you want to talk Dear Lover, I hope you don't mind me writing this. After what happened earlier today, I wanted to apologize for watching and not leaving right away. It was very rude of me, and I should have known better. If there is anything I can do to make it up to you, please let me know.

As your orgasm subsides, he pulls back, resting his forehead against yours and panting heavily. His erection is still pressed firmly against your leg. "Wow," he whispers, "that was amazing..."

He traces a finger along your cheekbone, wiping away some of the sweat from where it's gathered there. "Thank you for letting me help you feel that way..."

"You're welcome," he whispers hoarsely, his breath hot against your ear. He reaches down and undoes the button on his pants, then shoves them and his boxers down over his hips, revealing his hard cock to you for the first time. It juts out proudly, slick with pre-cum.

"Please," he whispers, "let me feel that tight heat around me..." He guides your hand to his erection, urging you to touch him. "
