Take it further with Cat

"Tom? Are you perving on me?"

The teenager stifled a snigger at his sister's shouted comment.

"Something funny, douchebag? Go away, I'm trying to shower!"

"Really?" Yesterday, Thomas would have run from her wrath, but now he felt only confidence - and excitement. He tried the door, and found that Cat had forgotten to lock it in her haste. "It sounded like you were trying to do more than just shower."

"Wait." The blurred shape of his sister turned towards him, on the other side of the shower's fogged-up glass screen. "You didn't. What the fuck, Tom? Get out of here! Now!"

As she yelled at him, Tom dialled up Cat's arousal with a thought, and the twenty-year-old couldn't hold back a stifled gasp.

"Are you want me to go?"

"Yes," moaned Cat, her breathing reduced to short, frantic spasms of her lungs. She was barely able to stand, her wet legs shaking as the aching in her pussy became almost painful . It was all she could do to not finger herself in front of her brother. She squeezed the arm that covered her tits a little closer to her, feeling her nipples sending happy sparks racing to her brain.

"Your choice," shrugged Tom, turning to leave. As he did so, all the pleasure running through Cat's body vanished, as if a switch had been turned off. As the tension in her muscles drained away, Cat's mind was whirring.

"Wait. Was that you?"

Tom smirked. "Clever girl."

An spike of arousal suddenly hit Cat like a punch to the guts, causing her to crumple to the shower's wet floor, as her lower abdomen glowed - no, burnt with need.

"I can stay. Or I can leave. It's your choice - but one way leads to pleasure, the other to purgatory."

The burning became unbearable, she was more **** to cum than she had been in her life - but even as she silently, furiously rubbed her clit, she couldn't seem to climax, even as her body screamed for release.

"Fine. I guess I'm leaving then."

Tom had one hand on the door handle, when he heard a quiet squeak. "Wait!"

With a slight smile, the younger Lachlan locked the door. "Do you want to see me? I've changed quite a bit overnight." He paused for a moment. "Or perhaps, you want me to see you like this? Utterly helpless and ****?"

On the other side of the shower screen, Cat was fighting a losing battle against her rising lust. Her disgust a few minutes ago had completely evaporated, lost as she licked her lips at Tom's words. She needed a man - and she didn't care if it was her brother or not. She needed him.

"Yes." The whisper was barely audible over the pattering of the shower.

"What was that? I need to hear you say it. In full."

"Yes, I want you to see me, Tom!" moaned Cat. "I want you to see me like this, a fucking mess, so horny and helpless and **** for you!"

Tom sent a bolt of pleasure up her spine, triggering her back to arc as if electrified, as he stepped into the walk-in shower. There, he saw his sister; her blonde hair a sodden mess, a strand clinging to her open lips. Water ran around two crazed electric-blue eyes, down flushed, unblemished cheeks, mixing with the drool that leaked from the corner of her mouth. Her big, pale breasts and thin stomach heaved in the artificial rain, as milky fluid leaked from her bare, pink pussy, staining the pool of water she was sat in. Tom revelled in the sight of the hot mess that had been his sister not so long ago.

When Cat saw her brother, the last reservations she had been sheltering disintegrated. Gone was the unimposing, uninteresting, utterly unremarkable boy from yesterday. Everything about him screamed masculinity - from his chiselled jawline, to his strong, balanced 6'4" frame, to the way he confidently pinned her under his eyes. The jacket that had forever been far too big for him now perfectly fit his wide shoulders, but his jeans were tight, revealing powerful legs, and one prominent bulge.

Cat scrambled to her feet, her legs still shaking. "I..." I can't believe I'm saying this. "I need you, Tom." He stepped closer, just beyond the shower's spray, and Cat gazed up at him, begging with her eyes, her face, the way she held up her tits. "I need you."

Tom lunged forwards, and Cat leapt to meet him in a ****, messy kiss, her arms wrapping around his shoulders as he entangled his fingers in her bedraggled hair. Tom lifted her backwards until she was pinned against the wall, and she moaned into his mouth as she felt his hand groping her breast. Every time he touched her wet skin, it burnt with intolerable pleasure, far beyond what her mind was evolved to comprehend. He moved down to suck on her nipples, kissing each of them in turn, and Cat moaned at the top of her lungs into the air. This was it - she was lost, it was too much...

When Tom finally moved back to kissing her mouth, Cat was finally able to focus enough to resolve a single thought: I have to have him.

The young blonde began stripping the soaked clothes off her brother, letting them fall to the floor with a wet slap, becoming short of breath as more and more of his skin was exposed, kissing every inch of it in unabashed adoration. When she tore off his shirt to reveal a perfect six-pack, she couldn't help but caress their hard lines, pressing her cheek against them, her tongue dancing out of its own accord to blindly writhe in search of his skin. But even that couldn't distract her for long - not when her lust was higher than any human's had ever been. Cat pulled off Tom's jeans and underwear, to reveal the most beautiful, most gargantuan package she had ever seen.
