She makes it perfectly clear

A look of hard lust came into her eyes. She stared unwaveringly at David and walked very steadily towards him. “I’ve been here months, maybe even years, I don't even know anymore. All that time without another human being who I could talk to, touch, kiss….”

David swallowed at began to back away from her. “Look, I can guess it’s been rough for you…”

Her lips parted and she began to breathe heavily, “Rough? You don’t have a clue. I’m a human being. A woman. I have wants and desires. I have needs.” She backed David up against a wall. She pushed he body up against his and ran her fingers up and down his torso. “Please…” she whispered, “Prove to me that you’re here. Show me that I haven’t gone crazy.”

David looked down at her mud-streaked face. He took it into his hands and kissed her lips. He said softly, “See? I’m real.” He let his own desire take over and picked her up in his arms. He carried her to gigantic master bathroom. They kissed each other with fierce passion and tore at each other’s clothes.

They stepped inside the shower, each still half dressed. She fumbled at the faucets, never letting her lips fall from his. Hot water poured over their bodies as they ripped what clothes they still had left off.

David kissed her neck and shoulders and quickly moved down her body to her breasts. She moaned loudly as her licked and nibbled at her nipples. Her fingernails dug into his back and soon found there way down to his buttocks. She kneaded and squeezed his flesh almost painfully.

He pushed her back against the tiled wall of the shower and lifted her legs into his arms. She kissed him hard and bit at his lips as he pushed himself into her. She screamed in pleasure as David’s hot stiff rod began to thrust in and out of her.

With the hot water pouring over them and a pile of wet clothes at the bottom of the shower, they let their lusts overtake them. They weren’t making love. They weren’t even having sex. They were fucking. They were fucking each other hard and fast, both of them trying to prove to themselves that they were here, that all this was real.

They eventually ended up on the bottom of the tub. Their clothes had partially stopped the water from draining. David kneeled between her legs, thrusting and withdrawing over and over again as water splash and squirted everywhere. Finally David could take no more he pushed himself deep inside her and he came hard. She gasped as his hot juices shot out inside her. He lay on top of her for a moment after he had finished. They were both gasping for air and exhausted from their furious efforts.
