There was a splashing sound and the constant gurgling from the overflow gutter.
A dim blue light illuminated the moist and steamy room.
The Doctor emerged from the water, heading for the edge of the pool and hurrying to reach the ladder quickly enough.
But he only reached the second rung before Jack surfaced;

"We're not finished yet," he spat between heavy gasps, thereby grabbing the kicking and screaming Time Lord and pulling him under water again.

The Doctor's world was turned upside down, flashing lights flickering in front of his eyes caused him to squint; the sudden inrush of noise ended abruptly and was followed by muffled silence. The Doctor opened his eyes in his light blue surrounding, hearing the TARDIS' soothing humming even underwater.
And the first thing he saw was Jack's crotch.

The Doctor tried to back away but Jack's hands were already buried in his hair, pulling the Doctor's face towards his throbbing member.
The Doctor opened his mouth slowly, trying not to swallow as he sucked on Jack's boner, feeling every strike on his soft palate.
The Doctor offered no resistance, nor did he try to free himself from Jack's grip, not even after dark dots started to dance before his eyes and the world around him became a darkening swirl.
Finally Jack pulled him to the surface.

"I don't want to drown you, a good shag would be enough, thank you very much," sighed Jack with a snappy undertone.
His words were lost on the Doctor, who tried to steady himself as he struggled for air.

"Oh, come on now," Jack dashed forward and grabbed the staggering Time Lord, embracing him affectionately. The Doctor rested in his arms and smiled mildly, nibbling on Jack's ear whenever he came within his reach.

"I love you, Jack," he whispered softly and tried to kiss him.

"That's the hypoxia talking, isn't it?" said Jack as he tried to drag the Doctor to the pool's edge.
The Doctor giggled, with a light-headedness that was somewhat beguiling.
Jack stared at the Doctor for a moment, obviously lost in thought.
Eventually the fifty-first-century-human-being-instincts kicked in, affirming that you can always make the best of it, adding 'what you don't know won't hurt you'.
And Jack hoped that it was true; because he wasn't going to go easy on the Doctor this time.

Jack embraced the Doctor, kissing his chest and neck as he moved lightly in the water; the Doctor offered no resistance and simply let himself get pushed and shoved through the pool.
Jack felt his blood rushing down into his pelvic area when he stared the Doctor's beloved body, the skinny and yet delicate structures, his beautiful complexion, his soft and tender lips...

Jack slammed the Doctor into the side of the pool in one quick move before forcing himself upon him. He nailed the Doctor to the tilled wall by grabbing his arms; he moved between the Doctor's legs, locking his legs into position by pushing his knees against the Doctor's thighs.
The Doctor stared at him with a look of mild confusion before putting on his dizzy smile again.
And somehow this was even more of a turn on for Jack.

Jack couldn't restrain himself any longer; in one quick move he pressed the dazed Time Lord against the wall and pushed into him, forcibly entering the Doctor's tense and vulnerable cavity.

The Doctor remained unmoved, Jack's harsh and sudden entering didn't as much shock as astound him. Barely in his right mind the Doctor's mouth dropped open; neither a word nor a sound escaping from his lips as he was still unable to speak.
And by his gleaming eyes Jack could tell that it was the inrushing lust that deprived him off his senses.
Every sensation was stimulating; every look of the Doctor reflected pure arousal.

And again, two words that tipped Jack over the top.

"Please, Jack."

Jack could barely hold back as he buried himself in the Time Lord, more intensely, more violent, just thrusting in and out, faster, always moving faster and faster; he picked up the pace to give the Doctor a good screw only to slow down again as he felt his muscles vibrating with the built up tension.

It must have been weeks if not months since he'd touched the Doctor.
And a couple of hours were usually sufficient for a human being from the fifty-first century for feeling sex-starved.

"Please, Jack...please..."

Jack pounced on the Doctor, smashing both of their by now entwined bodies against the tilled wall, penetrating him deeply, feeling the Doctor's twitching and throbbing insides, the hot movement, the unrestrainable urges, hearing the Doctor's constant pleas while he moved faster and faster, harsher and harsher, still pushing shamelessly into his sore entrance...
Hearing the Doctor moaning, whispering such sweet words...
...experiencing the fragile and skinny body beneath him, twitching uncontrollably with unprecedented uproar of pure prurience...
...feeling his own cock pulsating and swelling inside of the Doctor... stretching him... wearing him out...

And Jack stopped.
He felt the Doctor shivering beneath him and clutching at his warm body as his hot cum shot into his intestines.
The Doctor's sore cavity gaped uncontrollably as Jack removed his still swollen prick, the recent proof of love gushing out and mixing with the water.

And for the first time the Doctor looked him in the eye for real. His mouth was still open, though it was probably consternation which had overtaken bafflement.

Jack, quick reacting as always, hurled the Doctor out of the pool and onto the warm blue little tiles, which covered the floor with their beautiful pattern, and massaged life back into the Doctor's still twitching todger.
Then he caressed it with his lips.
He pressed the Doctor flat down on the tiles, kneeling above him and stimulated the soft skin between the Doctor's legs with practised preciseness.

The Doctor winced as he felt that he couldn't hold back any longer.
Jack seemed unimpressed, his constant movement slowly receding.
Eventually he swallowed.

The Doctor stroked Jack's hair before burying his fingers deeper into it; he pulled Jack up, meeting him face to face.
Jack searched his gaze.
Feeling the arising urge to say something romantic he whispered:
"From this moment...from this moment you will never be alone..."

The Doctor smiled, shaking his head slightly while he kept caressing Jack's cheeks.
He couldn't bite back a chuckle.

"Shame on you Jack."

And he sealed Jack's lips with a kiss.

Author's Note:
That's it! Thanks to all of you for sticking with the story!

What else can I say? It took me more than a year to finish this! (though I never thought I'd last that long)

The last chapter was a smutty one because I wanted to make the circle complete.
Feel free to leave a comment or even a complaint and let me know if you'd be interest in reading more Jack/Doctor stories like this one.
And once again, thanks for reading.
