Enjoy the privacy of Serena's room, then take a shower.

"Aaahh!! ...Uunnnggh!! .....Hiiihhhh!! .....s-shit, oh shit!"

It's coming again, my third orgasm in a row!

I bend over myself with my drooling mouth wide open while I keep drilling Serena's pussy with my right hand and obsessively stroking her right breast with my left.

The heat is coming back! I'm melting all over while my vagina closes around my fingers, almost like it doesn't want to let them go! I'm feeling the climax! Right there! Oh god, I'm cumming!

"MMNNNNNNnnnnnnnnnhhhhhhhh!!!!" I bite my lips to contain my whail of ecstacy. My knees are bent, toes clenching and I'm even twisting my engorged nipple, provoking me a sting of pain that gets immediately drowned within the waves of orgasmic pleasure.

I am... in paradise. There is no other way to put it.

After the orgasm fades away, I allow myself to fall back over the blanket, which by now is drenched in sweat, drool and love juices. However, I'm way too happy to care about the mess. Instead, I keep looking at the ceiling with an expression full of bliss and contentment.
So this my life now, huh?

I silently pat both Serena's massive breasts with the love and care as if I was petting a pair of sleeping puppies. And as I keep rubbing them, I slowly turn to my side, allowing the heavy orbs to fall and lie over each other, almost like piling up two gigantic water balloons.

After all the action I've enjoyed in this new body of mine, I've grown more and more comfortable with it. However, I can feel that my brain has barely started the process of actually getting used to this very unfamiliar physique. I can't blame it though. I've been a stocky fat guy for three decades and a thin voluptuous woman for less than a day. It's only logical that it will take some time before I stop spacing out every time I look down to see these massive female tits attached to my chest.

Not that I mind it though. The less accustomed I am to something, the more enjoyment I can get from it.

After a long self-indulgent pause, I stretch my limbs while purring like a cat, then slowly get up.

"Hey. You can look now." I say to the teddy bear facing the wall, which I proceed to put into the same position it was when I got here. "Sorry, Teddy, but I'd rather have you turned away than turned on."

I laugh at my stupid joke while I stand up and proceed to do a few more stretches in front of the mirror. Not because I need them, but because I like to enjoy my new flexibility... and also because twisting this body in such ways while being fully naked and covered in juices is way too hot to resist.

"Hmmm?" I stop for a moment realizing something, then I immediately raise my arm and place place my nose over the armpit. "...sniff... sniff... hoohh..."

Oh well, it seems that even the prettiest girls can't help but smell a little stale whenever they sweat too much and for too long.

"Looks like it's about time we take a shower, right Sera?" I say after licking my lips, deciding that 'Sera' sounds good enough to use as a diminutive for 'Serena'.

I still take a few more whiffs at my armpits and even at my feet, telling myself that it should be good idea to learn about the scents of my new body.
...However, I might be enjoying this stuff a bit too much for it to be only about research purposes.

After I'm done playing around, I grab a big towel and carefully step out of the room, intending to make sure that I'm not seen. I have a gut feeling that stumbling into Serena's annoying housemate while being totally naked is not a good idea right now.

"No one there..." I mutter while looking to the left. Then I blow a lock of dark brown hair away from my face and look to the right. "...and no one there."

With a playful smile, I take a few steps forward and reach to grab the knob of the bathroom's door.
But before I do, the door opens all by itself and I find myself facing the cute blonde girl who lives with Serena, who was apparently just using the bathroom. She freezes in place, opening her blue eyes wide while staring me down, and down... and down.

"Uh... hi." I say with unease, just as surprised as she is. Then I awkwardly press the towel over my wide bossom. "Are you... done?"

Blondie's eyes twitch for a moment, looking at all this plump flesh poking over the towel.

"W-What are you...?" She hesitates, apparently taken aback by her own stuttering. "What are you doing, walking around naked?!"

Her voice sounds rather high pitched. If I didn't know better, I'd say that she looks flustered?

"I just wanted to take a shower." I answer with an apologetic smile.

"Oh yeah? Then take your clothes off inside the bathroom instead of swinging your ridiculous udders around the house like a troglodite. If you wanna show off, then go to the pool or whatever! But not in my house, copy that?!"

"S-Sure..." I say after a moment, surprised by the girl's aggresive behaviour.

"Hmph!" She scowls at me for a moment, and then jolts forward, walking back to the living room in long quick strides.

Wait... is she blushing?

"Hmmm..." I furrow my eyebrows while staring at her back.
I could've sworn that she was blushing just now. Or was it just my imagination?

Well, whatever.

I close the door behind me and immediately open the shower tap. Then, after the water is finally getting hot, I step under the jet and allow the pleasant warmth to envelop the totality of my new feminine skin, allowing me to appreciate the difference in sensitivity between my original body and Serena's on an entirely new scale.

"..gasp..." I close my eyes while breathing slowly through my mouth, gleefully surprised at the unexpected bliss I'm getting from simply taking a hot shower.
The shift in sensitivity between my old loose skin in opposition to Serena's smooth and well cared for skin was something I didn't account for. Or not to such a degree. I'm melting... all over. The cascades of warm water are forming little streams peacefully flowing over the relief of Serena's curvaceous body, sliding around and between her bulky breasts, following the crevice of her lower back and entering the plump valley between her soft buttocks. There are drops of water dripping from the girl's sensitive nipples and the added weight of my now soaked hair over my right shoulder.

And I'm feeling every single thing. It's like I'm melting... all over.
It's so hard to believe that a person can feel this good from just an ordinary shower. This is so... so...

"...unfair....." Those two syllabes are all I manage to utter with my head becoming as foggy as the bathtub itself.

I can hardly stay still... My body is starting to sway a little...

......

..........

"WOAahh!!" I suddenly yell when I almost fall forward, which would've ended with my head hitting the glass door.

What was that?!

I chuckle in realization.
Don't tell me I was dozing off while standing under the shower. Holy crap, that could've ended up bad.

"I'm such an idiot." I say while still laughing.

I wisely decide to do what I came here for. So, after making sure the magic pendant is right where I left it (near the sink), I grab the shower gel and begin the pleasant process of washing my borrowed body.
