The Professional Standard.

From his vantage point, sitting there savouring the delightful yeasty flavours of his can with his tongue and his eyes upon the sight of his beloved girl in the arms of a rather attractive and curvy Latina futa girl, he could feel the beginning stages of his own warmth descending down to his own loins. For her ministrations, Isadora was, of course, more than aware of his presence, and to that end, effected a more slow, tempting and seductive rhythm as her lips and tongue intertwined with Martine's.

*Sip*

Another drop of that delightful Lager found itself down his throat as he began to cup and rub his stiff cock, still enmeshed within his clothing. The two girls meanwhile had, in their passion, discarded their upper garments, Martine simply dropped hers to the floor, revealing a modest but attractive B cup breasts, for her efforts and experience however, Isadora had slowly and sensually removed hers, giving her far more enhanced upper decking a delightfully teasing wiggle for their observer.

Now as they once more moved into resuming their passionate kissing, both girls began to explore each others upper body with their hands, their mutual upper nakedness transferring body heat just as surely as their own tongues explored each other. He marveled at the sight of their breasts colliding like two gladiators fighting for supremacy, his own girls dwarfed by Isadora's and yet...such added to the dominant and yet stimulating atmosphere of the room. Isadora, with her knowledge of all things seductive and carnal, cut a brilliant figure not only stood now embracing Martine, a delightful colour contrast of her coffee with Martine's milk, but also in the slow and deliberate effect she was putting across, titillating the client who hired her and building up anticipation in both him and Martine. She was not going to hurry unnecessarily.

Isadora reached down to grasp and cup the cute derriere of Martine's, whilst it might not have been gargantuan like hers, it had, she had to remark, it's own character and curvaceous shape, a delight to the eye and more to the point, in her hands. She momentarily released her mouth from Martine's who was breathing heavily with barely concealed lust at this point, remarking briefly with her eyes the figure of Darren sitting near, on the beginnings of his second can by now, she flashed a cheeky wink as she rotated Martine with her back to him, and reaching down, slowly slid Martine's pants off, revealing his girl's bottom previously concealed and now hungrily chewing a thong between its cheeks.

To further stimulate their voyeur, she stood with her own back to him, next to Martine, only instead of simply dropping, she bent forward at the waist, bringing her ample rear to fill out the back of her pants to the **** and then slowly wiggling from side to side, gently lowered her own pants, revealing her own enormous derriere also ensnared by a thong, a picture not gone unnoticed by Darren, like two scoops of both Vanilla and Chocolate ice-cream next to each other. His own response was simple...

*Unzip*

Once more embracing and kissing each other, now Isadora led herself and Martine to the bed...

*Fwumpf*

They landed atop the covers, muffling their descent, hands still explored each other, the heat of their shared bodies interrupted only by Martine's obviously breathy longing, anticipation...

Oh good lord I want her...I want her while my boyfriend watches....so turned on right now!

Looking over momentarily at Darren she could see him alternate between soft strokes of his cock and his beer, utterly transfixed by the sight of her and Isadora. Without warning Isadora flipped her onto her back, moving in between her legs, she slowly removed Martine's underwear, slightly damp by her seductive ministrations, she cast them aside and bending from the waist, so that her ass was deliberately in the air, showing off her round and jiggly bottom encased with but her skimpy thong, she brought her lips down to Martine's eager wet slit, and began to lick her, moving in a figure of 8 across her engorged and aroused labia, steadying herself on one elbow and using the other free hand to gently rub Martine's clit, the sensations caused her to breathe even more heavily...and soon enough faint moans could be heard.

"I....ahhh....that....that's...."

"It's okay Chica, let me do what I'm good at...."

Waves upon waves of decadent pleasure cascaded across her form from the waist upwards and radiating down to her toes, the nerves stimulated to maximum effect as a result of Isadora's experienced and tender caresses with both hand and tongue. The sound of licking and wetness could be heard and Darren by now was near apoplectic in the increasing temp of his own self stimulation.

But even that feeling was soon surpassed as, bringing that free arm behind herself, her ass still up in the air facing him, Isadora slowly retrieved a condom tucked into the waistband of her thong, and slowly brought it down and freed it one leg at a time, not missing her tasting of Martine, like a fine wine, and then throwing them to the floor, Darren saw once again that brown coffee coloured Latina cock, only this time he watched as from a semi-flaccid state it soon began to engorge, swelling, almost pulsating with blood in order to perform that biological imperative all of us have, with deftness she opened the condom packet, a nice clear colour condom emerged into her hand, and with skill, skill that had been practiced many a time, with but one hand she rolled it down the length of her long and girthy shaft.

Then bringing herself up a little she planted kisses first up Martine's navel, up to her breasts and kissing them in turn, until finally kissing her neck, she took her free hand and guided her now condom clad cock, and after an initial tease of rubbing her cock up and down Martine's Labia once more, she sheathed herself fully into her wet and welcoming depths.
