The Doctor managed to slip his hands out of the ropes that held them behind his back. Ruby Sunday had been tied up, wriggling to try and free herself, for what felt like an eternity. She breathed a sigh of relief. Her strange companion was free and would surely untie her next.

The Doctor approached Ruby, his long brown coat billowing behind him as he walked. His eyes were fixed on her body, the tight skirt barely covering her ass, her tights and boots completing the sexy ensemble.

"Doctor," Ruby protested, "are you going to untie me or not?"

The Doctor didn't answer. Instead, he reached out and touched Ruby's cheek, his fingers tracing the curve of her face. Ruby felt a shiver run down her spine as he did so, her breath hitching in her throat. He crouched down next to her, with a grin. "Maybe in a minute, honey" he whispered.

The Doctor's hand moved down to Ruby's chest, his fingers brushing against the swell of her breasts. Ruby's nipples hardened under the red jumper she was wearing, and she moaned softly as The Doctor continued to touch her.

"Doctor, please," Ruby begged, her voice trembling.

The Doctor ignored her pleas, his hand moving down to Ruby's skirt. He slipped his fingers under the fabric, his touch sending waves of pleasure through Ruby's body.

Ruby's pussy was already wet, her juices soaking her tights. She could feel herself getting tenser, and she moaned louder as The Doctor continued to touch her.

The Doctor's fingers moved to Ruby's tights, pulling them down slowly. Ruby's pussy was now exposed, and The Doctor's fingers moved to her lips, parting them gently.

The Doctor's found Ruby's clit, rubbing it gently. Ruby moaned louder, her hips bucking against The Doctor's hand. She could feel herself getting closer to orgasm, her pussy clenching in anticipation.

The Doctor's other hand moved to Ruby's breasts, his fingers pinching her nipples through her jumper. Ruby moaned even louder, her orgasm building inside her.

The Doctor's fingers moved faster, rubbing Ruby's clit harder. Ruby's hips bucked wildly, her orgasm exploding through her body. She screamed, her pussy clenching around The Doctor's fingers.

The Doctor pulled his fingers out of Ruby's pussy, bringing them to his mouth. "Not bad, babes." He licked them clean, his eyes fixed on Ruby's face.

Ruby's eyes were half-closed, her body still trembling from her orgasm. She looked up at The Doctor, her breath still coming in ragged gasps.

"Doctor," she whispered, "please fuck me."

The Doctor smiled, his eyes gleaming with desire. He stripped off his coat and bright orange shirt. He unzipped his pants, his hard cock springing free.

Ruby's eyes widened as she saw The Doctor's cock. It was long and thick, and she licked her lips in anticipation.

The Doctor untied the ropes binding her at last, easing them away from her like he was negotiating with them. Once she was free, he rolled her jacket off her shoulders, kissing her neck. Then he tugged her jumper up and over her head, revealing her heaving breasts struggling to escape her bra.

The Doctor gently pushed her shoulders down to the floor, and positioned himself between Ruby's legs. He rubbed the head of his cock against her pussy, teasing her. "Come on," Ruby whined. Her hips bucked against The Doctor's cock. She wanted him inside her, badly.

The Doctor finally pushed himself inside Ruby, his cock sliding deep into her pussy. Ruby moaned loudly, her pussy clenching around him.

The Doctor started to fuck the gorgeous little blonde, his hips moving in a slow, steady rhythm. Ruby moaned with every thrust, her pussy getting wetter and wetter. Her Mancunian accent got thicker and thicker as she grew more frenzied.

The Doctor's thrusts became faster and harder, his cock pounding into Ruby's pussy. Ruby screamed, her orgasm building inside her again.

The Doctor's cock twitched inside Ruby's pussy, and he groaned. Ruby moaned, her orgasm exploding through her body.

The Doctor collapsed on top of Ruby, his cock still inside her. Ruby wrapped her arms around him, her body still trembling from her orgasm. The Doctor looked down at Ruby, a satisfied smile on his face. "I hope you enjoyed that," he said, his voice gentle and sweet.

Ruby smiled. "That was amazing," she said, her voice trembling.

The Doctor pulled out of Ruby, his cum dripping out of her pussy. He got up, pulling up his pants. "You think that was amazing? I've barely started."

He yanked her to her feet, suddenly full of energy again, tossing her her clothes. She watched as The Doctor put on his coat, her heart still racing. "Come on Rubes," he grinned, "we've got a baby to save!"

Ruby lay back for a moment, her body still trembling from her orgasm. She closed her eyes, a satisfied smile on her face. The Doctor had fucked her, and she had loved every minute of it. Then she pulled her clothes back on and charged after him into adventure.
