Follow the trail and get some answers

 Lara grabbed her holsters, equipped with two fully-loaded desert eagles, wrapped them around her naked hips, then headed out into the darkness of her front yard. 

Ahead of her she could see the glistening wet footprints leading off into her hedge maze. "Following an invisible man through a dark labyrinth is not what I expected to be doing tonight," she muttered to herself as she passed through the green archway.
She was only slightly comforted by the fact that she knew this maze like the back of her hand, even at night. She headed left and skirted the side of the wall, keeping in the shadows.
As she moved, the only sound audible was the rustling of the wind through the leaves of the hedge maze. She paused at a four-way junction and crouched, inspecting the ground.
The wind picked up and she shivered, her naked and still wet chest heaving as she felt her nipples harden. She inched forwards, keeping her eyes on the disappearing trail of her assailant’s footprints, which headed straight forward, towards the center courtyard of the maze. Upon reaching the pool in the center courtyard, the footprints stopped.
Lara remained totally still in the shadows, eying every inch of the courtyard with scrutiny, trying to find some hint of the invisible attacker. Even in the cold night air she began to sweat, nervous that she had no clue where this invisible man was.
He could be right next to her and she would have no clue. As if in response to her thoughts she heard a rustle to her right. She felt two warm hands grip her head and **** her to her knees. As she reached for her guns her head was suddenly released, but her hands were bound instead. She looked around wildly as she felt a rough cord tied around her wrists, which were now **** behind her. She sees nothing. All of a sudden she was released.
She stood up quickly, with her arms bound tightly behind her back forcing her large breasts forward into the night air. She began to step slowly backwards, towards the exit to the courtyard when she felt a sharp kick to the back of her legs, forcing her to her knees again. The invisible attacker grabbed her hair and pulled her head forward. She let out a shriek of pain which was suddenly stifled by eight inches of warm erect cock.
Her eyes bulged and she sputtered and choked as four more inches were **** into her mouth and down her throat. She could feel the hands **** her head back and forth across the slick member, using her oesophagus as a fuck-hole. Her saliva coated the entire invisible cock and it began to slide in and out more easily.
Soon the rocking motion became gentler and Lara began to relax. It had been a long, long time since she had deep throated anyone and the taste of the pre-cum as it trickled down the back of her throat made her lust for more.
She began to moan in the pit of her stomach sliding her head of her own will, faster and faster, wrapping her pink tongue tight around the base of the shaft and then keeping it tight as she stroked up it to the head. Her nose was mashed repeatedly into invisible pubic hair and she thought about how funny she must look: sitting here entirely naked with her mouth in this O shape, jerking back and forth, moaning like a cat in heat. God she wanted to taste that cum. She moaned deeply for it around the cock. Suddenly she felt the engorged member jerk back before erupting, shooting warm semen down the back of her throat.
It filled her mouth and she practically screamed in orgasm as it coated her huge breasts, making them sticky and white. Then she stopped in surprise - She could see the white semen erupting from thin air! Lara stood up suddenly and spit her mouthful of semen into the air in front of her. Quickly the outline of the invisible man's head came into view, revealed by his own semen. Now that she could see some sign of the man, she kicked outwards, towards his invisible chest. She heard a thump and a crackle as an imprint of a body was made in the soft grass. The body didn't move, she must've knocked him out. She began to struggle against her bonds and as she got loose she saw the form of the man begin to fade in. He was entirely naked, about 6"1' and handsomely built, save for the large black bruise that was forming where she had kicked him, but his head was still invisible.
As the man opened his eyes he was met with the sight of a gun barrel and the smiling visage of a stunningly naked Lara Croft covered in his semen. Lara grinned through the cum and said "Well, let's reverse the roles, shall we?"
