As he watched his girlfriend Emma wiggle her tight little behind at him, Tim couldn't help but feel an overwhelming sense of excitement. The mere sight of her amazing ass in those tight jeans was enough to make him breathless. He knew he couldn't wait any longer; he had to have her.
Slowly approaching from behind, Tim slid his hands around Emma's waist and gently massaged her soft skin. His cock throbbed with anticipation as he nuzzled his face against her neck, inhaling her sweet scent. Emma let out a contented sigh, her body melting into his as she leaned back against him.
"You're killing me, Tim," she murmured softly, her voice shaky with desire. "I hope you know what you're doing."
By now, Tim was beyond reason. All he could think about was burying his cock deep inside Emma's tight ass. Without another word, he slipped his hands under her shirt and bra, his fingers tracing the outline of her perfect breasts before finding their way to her wet, eager slit.
Emma let out a soft moan as Tim's fingers teased her clit, his cock throbbing harder than ever behind him. Inch by inch, he pressed himself against her slit, feeling her hot juices soak into his boxers. Unable to resist any longer, he slowly slipped his cock inside her, filling her up with each thrust.
"Oh God, Tim," she gasped, arching her back as he entered her completely. "That feels so good."
Tim lost himself in the sensation of being buried deep inside Emma's tight ass. He grasped both of her cheeks in his hands, squeezing them gently as he began to thrust into her with a steady rhythm. It wasn't long before he felt the familiar pressure building up inside her - he knew she was ready to take his cum.
With one final, powerful thrust, Tim let loose, filling Emma's ass with his hot, sticky semen. She groaned loudly, her body shaking as wave after wave of pleasure washed over her. For a moment, they remained connected, panting heavily as they basked in the afterglow of their passionate encounter.
"I can't believe we just did that," Emma said, her voice still shaking with emotion. "But it was amazing."
Tim pulled out of her slowly, his cock slipping out of her ass with a wet, satisfying sound. He stepped back to admire her perfectly-filled asshole, glistening with his cum and her juices. He had never seen anything quite so beautiful.
"I love you, Emma," he said simply, his voice thick with emotion. "You're perfect."
Emma reached back and touched his cheek softly. "I love you too, Tim," she replied, her voice barely above a whisper. "And thank you."
They shared a tender kiss, their mouths still taste bud of each other's cum. As they pulled apart, Tim could feel his cock starting to stir again, already anxious for their next encounter. It was clear to him that he had found the perfect natural scat girl to share his deepest desires with.
"When can we do this again?" he asked playfully, grinning from ear to ear.
Emma blushed, biting her bottom lip nervously. "I don't know, Tim," she replied hesitantly. "I've never done anything like this before. It's... it's a lot to take in."
Tim stepped forward, cupping her face gently in his hands. "Don't worry, baby," he assured her. "We'll take our time. But know this: you're mine now. And I'm going to fuck your asshole until you can't even walk straight."
Emma giggled shyly, feeling a shiver of excitement run down her spine. She couldn't wait to see what their next adventure would hold.
