Lara does

The surprised guard was no match for Lara, who struck him in the face with a mean right jab, followed up by knee in the gut, and a quick strike over the neck, the last blow rendering the poor bastard ****.

Not wasting a second, Lara was on him, stripping him of all the gear she could have use of.

Since she had lost her shotgun to the riverbed, she decided that the guard's M-4 carbine would do nicely, then she grabbed his set of keys as well; she could use them to get the gate open so that she could retrieve her backpack, and finally she grabbed his com-radio, it could very well be quite useful to bypass other guards with.

It was only now, that Lara was done with searching the guard, that she noticed a certain sensation of arousal that the fight had caused on her. Her cunt itched rather intensely, and Lara had subconsciously begun to fondle her twat with her left hand while her mind had been pre-occupied with the com-radio. "Strange," Lara thought as she felt her fingers explore her own crotch, "I know I've always been an adrenaline-junkie, but never like this! It must have something to do with the stone. Well, I guess I'll have to tie this sod up and get a hold of my kit before I do something about it."

Lara looked around once again in the boat-house, which wasn't all that easy, considering that her flashlight was keeping her gun company in the water, but she managed to feel and look around enough to realize that there was no rope to be found.

One did not become a tomb raider without possessing a certain resourcefulness however, and Lara quickly came up with a satisfying solution, having found a sturdy pair of scissors. She would strip the guard of his clothing, then cut it up and use the shreds to tie him up and gag him. Said and done, she removed the guard's shirt, revealing a muscular torso, and unbuckled the belt to his pants, pulled the buttons up and began to pull them off.

Lara's already wet cunt rapidly moistened as she saw the bulge formed by the guard's cock as it strained against the boxers he was wearing. Licking her lips, Lara decided that the guard should be naked as well if she was, and as soon as his pants and boots were off, the guard was liberated of his underpants.
Nearly drooling as her eyes fixated on the sight of the guard's limp but still huge cock, Lara managed to break the spell and told herself that work comes first, and that massive penis would still be there when she had the guard gagged and bound.
In the background, she thought she heard an engine, but she did not waste more attention to that, but began instead to shred the guard's clothes.

That took her a few minutes, but the guard seemed to still be knocked out, and nobody seemed to missing him, and there was nothing but static on the com-radio. Eventually, the guard was bound and gagged in a proper manor, and Lara was heading for the door, to retrieve her backpack before someone found it and raised the alarm.

Using the guard's key to coax out her own from the other side of the lock, Lara got the door open, listened carefully for any sounds, grabbed the handle of the carbine tighter, and then swung the door open slowly.

There was no one in sight, so Lara quickly grabbed her kit and closed the door gently behind her. Finally, she could pay the fire that was raging in her groin the proper attention! Her clit was already protruding out between the thick, meaty lips of her labia, her neatly shaven cunt growing wetter still as she got down on her knees next to the **** guard. Her right hand closed around his thick penis, holding it in a firm grip, squeezing it lightly while moving back and forth over it, slowly pumping it into hardness. She could hear a muffled moan from the guard as her attentions to his cock brought him slowly back to consciousness.
Her left hand, meanwhile, had found its way to her own genitals, and was busy caressing her throbbing clit.

When she had established that the penis in front of her had been enlarged in full, Lara bent forwards, lifted the cock upwards with her right hand, revealing the guard’s pair of heavy, cum-filled testicles. At first, she licked the sack with great care, arching her tongue to fully coat them with her saliva, then she sealed her lush, full lips around the left testicle, sucking it with great **** while her tongue kept fondling the testicle. The guard, a fellow by the name of Javier, could not believe what was happening. The same gringo bitch that had knocked him out was now busy sucking on his balls!

Having regained his senses, while Lara moved on to his left testicle, Javier tried to stretch the strips of cloth that kept him in bondage, but to no avail, the knots were too strong and Lara had doubled the layers of cloth from fear that it would be to easy to get loose otherwise.

Feeling satisfied with her work on Javier’s nutsack, Lara moved on to the cock itself, her tongue making contact with the cock-meat just above Javier’s balls, her lips pressing against the broad phallus as she slowly worked her way upwards, her tongue never ceasing to lick the cock.

Javier lost all will to break loose when Lara's lips reached his head, he looked down to see how her tongue swirled in circles around, her right hand pumping his penis slowly and he could see that her left hand was buried in her own crotch. What a slut!

Lara stopped licking, opened her mouth wide, and engulfed the throbbing penis, her mind set on swallowing it all. It wasn’t easy, she nearly gagged halfway to the hilt, but managed to breathe through her nose, pressing on slowly but determinedly. She let out a muffled cry of joy when she felt her nose being tickled by his curly pubic hair, a sure sign that she had reached her goal. It felt as though it was years ago since she had last enjoyed the taste of cock! Lara now began to bob her head up and down the considerable length of Javier’s penis, working up an awesome rate, while her right hand fondled his aching balls.

Javier could not stand up for long against such an onslaught, and within a few minutes, his moaning reached a peak as his cock tensed up, before releasing a torrent of cum down Lara’s throat. Having swallowed the first jet of cum, Lara quickly released the cock from her mouth, just in time for the second wave hit her in the face, pearly white semen splashing onto her tanned skin. The sensation of cum covering her face and gushing down her throat was all that Lara needed to push her over the top, and she came as well, panting heavily while her cunt flooded, pressing her face against Javier’s thick cock, smearing in the last of his cum to her skin.

While the orgasm subsided, Lara noticed that the engine-sound had grown louder.
