Kaz moaned into my mouth as she mounted me, breathless and soft; her body felt perfect against mine, thighs against my hips as her plush perfect butt settled against me. She leaned forwards, her breasts pressing into my chest, warm and pillowy, as her kisses became less and less distinct from her moans and swears.
'
So fucking good... you feel so good... God, how are you still so hard...
'
We had taken a break after the first round in bed, after which Kaz had fallen asleep against me. A couple of hours passed, and while I had tried to sleep, I simply couldn't. My mind was racing. I'd taken the time to explore what
changes
had been made to me when Kaz had - without intention - shot me with the Peredi with the setting on 'Lover', and it was clear that there was more to it than I had originally thought.
For one thing, obviously, I was... larger. My cock still had the same proportions it had always had, with a slight widening in the middle and a bit of a curve to it. I was uncut, and the foreskin stretched over the head in the same way it always had. It was all simply... bigger. Sized-up. And, if I had to be honest, I liked it - and Kaz seemed to enjoy it, too.
But there were other changes. Something else that seemed to have been sized-up were my testicles; they were heavier in my hand, and I could tell they had been increased in some way. Perhaps not by the same metric as my penis, but enough to be noticable. It also occured to me that they had maybe been altered due to the fact I had also seemed to have had my refractory period
considerably
shortened. Maybe the balls were heavier to just keep up with demand?
Beyond the strictly sexual, however, there were other changes. My chest and arms felt a little more toned, and I could tell immediately that my skin was completely clear - I'd always had a slight issue of acne across my chest and forearms, but it had completely cleared up. There was also a change to my smell; we'd been fucking now, on and off, for multiple hours, and I didn't stink. In fact, while there was
something
of a musk, Kaz seemed eager to breathe it in, having on a few occasions commented on how 'manly' I smelled. Whatever that meant, I wasn't sure, but I wasn't going to argue. There was also the last
physical
change I had noticed so far, which was my tongue. I hadn't even really noticed this during our kisses - which made me wonder if Kaz had realised either - but when I stuck my tongue out it was now able to stretch a good inch below my chin. I'd realised it almost by mistake, yawning, but the revelation was one I filed away for later use.
Kaz had also theorised that I had started to give off pheromones that were making her unable to resist me - an idea I wasn't sure how to feel about. Sure, she was a girl I had crushed on for years, and she'd told me that she'd always fancied me too, so it wasn't like we were acting
against
our previous impulses, but the idea that we had only done what we'd done because of the changes made to me was... uncomfortable.
Of course, having Kaz orgasm over and over again as we fucked made it hard to convince myself she wasn't enjoying things.
'
Fuck me, Will
,' she moaned into my neck, pulling me out of my thoughts and back to the
incredible
reality before me.
I wrapped my arms around her, and rolled; without falling out of her, I got Kaz on her back, the mess of pillows and bedding around us shifting as I kissed her, and sank myself
fully
into her stretched sex.
She moaned, a wordless beg for me to fuck her, to use her, to make her cum again, but insteas I simply stayed there, holstered within her, one hand on her neck and another on her breast. Her hands were in my hair, as she began to beg.
'
Pleasepleasepleasepleaseplease
-'
'Kaz,' I whispered. 'Do you think I'm still...
myself
?'
Her eyes opened, and she softened. 'Yourself?'
I faltered. 'I've changed, and... I'm worried that I'm affecting you. Making you do things-'
She shut me up with a kiss, pulling my face towards hers. When she let go, she was laughing a little, through the breathlessness. 'You are... adorable, Will. We're doing this because we both want to.'
'But, like you said - pheromones, or something. What if this isn't what you
actually
want?'
'I've wanted to fuck you for a
while
,' she said, moving her hips a little, up and down, sawing me in and out of her just a little. She sighed, enjoying it. 'And... you have lived up to and smashed
all
expectations. In the morning, I'll leave and wait until whatever pheromones you've maybe put in me have faded, and we can talk over the phone. See if I still want the best sex of my life then.' She said that last bit like she'd already made her mind up, but I actually liked that idea.
'Okay,' I said, kissing her again. 'You are... incredible, by the way.'
She grinned. 'I know - now, make me cum, or I'm going to have to edge you.' I felt my heart lurch at that, and I think my cock
physically
flexed inside her. Her eyebrow popped up. 'Wait - would... would you like that?'
I faltered a bit. 'I- I don't know. I know
what
it is, but I've never... Do you like that?'
She blushed a little, and I saw how adorable she was when she felt a little sheepish. 'Honestly? Yeah... I like how it makes me feel wanted, you know? Don't get me wrong, it's not what I
always
want, but...'
'Do you want to?' I asked. '...now?'
Kaz bit her lip, a small smile on her face. 'Make me cum one more time - and then yeah, I can do that for you. If you want.'
I kissed her again. 'O-okay. Yeah, I think I would, yeah.'
She looked like she could burst, a glee in her eyes I hadn't really seen before. 'Just to say, Will - I... thank you.'
I faltered, even as she began to rock her hips again, moaning beneath me. She felt so amazing, and I'd already been brought to climax with her a few times; the idea of her teasing me was... enticing.
''Thank you'?' I asked.
She nodded. 'You are
amazing
- and I know we're literally just getting started, but... whatever that thing did to you - the Peredi - I want to explore
all
of it with you.'
'Really?' I asked.
She grinned. 'Fuck yes - are you joking?!'
'Well,' I smiled, leaning in. 'There's something I haven't shown you yet.'
She narrowed her eyes. 'Oh?'
In response, I opened my mouth, and let my long tongue roll out, stretching it as far down my chin as I could. I watched Kaz's eyes dilate a little as her mouth fell open.
'New plan,' she said, voice cracking a little. 'On your back -
right
now.'

'
Please - please - please-'
I didn't have it in me to say much of anything else, and even then my words were muttered from beneath the slick wetness of Kaz's sweet sex. I writhed, but the moment I moved too far, she lowered her backside back onto my face, punishing me.
'One more, and then we'll see,' she moaned as I obeyed, sliding my tongue into her. It should have ached - I should have been
begging
