A dark plan

Author's note: Sorry for the inappropriate clothes. It's nigh-impossible to find suitable images with wizard robes.

The next morning, an Auror came to check the prison. When he went across Delphini's cell, he was surprised: She's eating a banana.

"What are you doing?"

"Enjoy my meal, of course. There are not many things to eat here, let alone something delicious."

The Auror felt a bit uneasy. He waved his wand, conjured a chair, and sat down.

"Are you suspecting me? Observe as you want. This is within your right."

Soon after, the Auror couldn't move his gaze away. Delphini has unbuttoned her shirt, revealing her buxom. She licked the banana in such a lustful way, giving him a boner.

After the banana was consumed, Delphini suddenly said: "It's so boring. Hey, do you want to have some fun with me?"

The Auror received a surprise hit: "No, I..."

"Come on, don't try to deny it. I can see your hard thing from here. What's your name?"

Delphini sounded so charming, the Auror felt like he shouldn't refuse her: "M... Matthew."

"Matthew, I haven't gotten laid for months. No one will know. You can easily overpower me. Let the wand out of my reach and you have nothing to worry about."

Her last sentence has convinced him. Without a wand, she's just a helpless girl. Matthew placed the wand on the chair, opened the cell, and walked inside. Meanwhile, Delphini removed her upper clothes: "Let me service you first."

Squatting down, she gave him a faint smile before unzipping his pants and revealing his hard cock. Not too terribly large it was well-shaped and nicely veined. She lifted it and placed her lips over the tip. “Hope you like my blowjob,” she murmured as the shaft entered her mouth.

Delphini let the cock go deep into her throat. She swiped her tongue over each sensitive spot while letting it press into her cheeks from inside. Matthew growled as he enjoyed the tight viselike grip of her tongue. He was lost in the wet and warm sensation, not noticing that Delphini was chanting some spells. Finally, he reached the edge of the climax, but before he went past the line, she pulled the thing out.

"Come on, please save it to the main dish."

Delphini placed a deep kiss on Matthew's lips. She could feel his desire pulsing through his body. All he could think of now was the sensation of rammed his cock into a real pussy, pressed up deep inside her. She wanted it too. "Fuck me," she whispered to Matthew. "Fuck me hard."

Matthew didn't need to be reminded twice. He grabbed her thigh and lifted it high to expose her vulva before he impaled her with a swift move. Then he began to move in a steady rhythm. Delphini could feel herself being jerked forward with every hard thrust. But she couldn’t get enough. Each hard plunge of his cock made her rise just that much higher towards ecstasy. She could feel her pussy tightening and her stomach clenching in preparation for the ultimate explosion. But she couldn't give in to the pleasure now.

She raised her hips a bit and began to apply pressure. Being smacking hard by her pussy, Matthew felt that he couldn't control his legs anymore. They stepped back until fell on the bed. Delphini successfully changed to the cowgirl position. Now she was the one who gained the initiative.

She could feel every inch of his cock rubbing against her inner walls each time she moved. The growing of his cock inside her, lubed with her own juices, almost driving her crazy. But above all came the awareness that her plan was about to succeed. She could feel his balls tightening and knew he was close to coming and filling her hungry pussy.

“I want you to fill me up with your cum,” She moaned, pressed harder so he couldn't stand up or pull out, "Obey your instinct and give me your hot semen."

Matthew completely forgot about everything else, his mind was filled with the thought of breeding his mate. He roared, slammed into her one last time, the thrust made his cock penetrated through her cervix. Delphini felt his cock pulse inside her, releasing the hot jets of his baby-making juice and sending her into her own orgasm. Her inner muscles clenched and squeezed his cock, milking him of every drop of semen and pulling it into her womb where the seed would take hold.

Gasping for breath, she slumped down as Matthew withdrew his softening cock from her. At that time he finally realized what he has done. Delphini smiled and said: "Rest assured. What happened in this cell stays in this cell."

He looked at her one last time before he went to check other places in Azkaban. Being left alone in her cell, Delphini placed her hand on her abdomen and began to chant. When she gave Matthew a blowjob she cast a spell that increased his fecundity, now she cast another one to induce her ovulation. Together, they would make sure she got knocked up.

Soon later she felt a circle appeared around her navel, then it faded quickly. That meant a sperm has met her egg and successfully impregnated her. Delphini smiled: All according to father's plan.
