Rudy couldn't help but chuckle at Rias' seductive phrase, his desire for her intensifying with each passing moment. As their lips collided in a passionate kiss, his hand moved with purpose, his fingertips brushing against her sensitive bud. Rias moaned into his mouth, her hips instinctively grinding against his touch, fueling their shared pleasure. Their kisses grew more fervent, lips hungrily exploring one another, as Rudy's touch became more rhythmic, rubbing Rias' clit with a tantalizing pressure. Her moans grew louder, her body arching against his hand, begging for more.

Rias could feel the waves of pleasure building within her, her body yearning for release. But just as the intensity reached its peak, she abruptly pulled away from Rudy's touch, a mischievous glimmer in her eyes.

"Not yet," she whispered with a captivating smirk, her voice thick with desire. "I want to prolong this delicious torture. I don't want to cum again like this."

"Hmm? This is the first time where a girl 'stopped' me from making her cum. Usually they beg me to continue and I stop purposely to tease them a little," Rudy said with a surprised look on his face.

With a sultry voice that dripped with need, Rias pleaded, "Rudy, I can't wait any longer. Plug your throbbing dick inside my wet and trembling pussy and make me cum."

Rudy positioned himself between Rias' parted legs, his gaze locked with hers, filled with a mix of love and carnal desire. Slowly, he traced the outline of her swollen lips of her pussy with the tip of his cock, teasing her with each tantalizing touch.

Feeling Rias quivering with anticipation, Rudy's hand moved with purpose. With a whisper of an incantation, his fingers delicately caressed her clit, casting a spell that would ensure her pleasure and remove any pain that awaited her.

A soft moan escaped Rias' lips as waves of warmth and pleasure pulsed through her body, enveloping her in a haze of ecstasy.

"Hey~" She let out a soft moan. "I told you I want to cum with your dick~"

"I know. I am just dulling your pain receptors so you wouldn't feel any pain when I penetrate your tight pussy."

As Rias felt the warmth of Rudy's spell being cast, she instinctively stopped him. She gently pushed his hand away, shaking her head with a captivating smirk playing on her lips.

"Wait…" she whispered in a voice laced with a fiery craving. "I want to feel every sensation, every throb of pain and pleasure as I become a woman."

Rudy's eyes widened with a mixture of surprise and concern, but a flicker of understanding sparked in his gaze.

"It's funny how mom stopped me from doing that too…"

'These girls can go to crazy length for love, alright.'

With a deep breath, Rudy positioned his dick at the entrance of Rias' wet and trembling pussy. Slowly, he slid the tip of his throbbing cock inside her, savoring the tightness that enveloped him.

Rias gasped, her eyes widening with a mixture of pleasure and anticipation.

As Rudy continued his slow and steady thrusts, Rias could feel a mixture of pleasure and slight discomfort. Her expression flickered between a soft wince and a passionate longing. Her body gradually adapted to the sensation, the pain giving way to an exquisite blend of pleasure and fulfillment.

Rudy's eyes remained focused on Rias, his love and concern radiating from his gaze. He could sense her vulnerability, her willingness to embrace both the pleasure and the pain in their intimate connection.

Rudy's thrusts quickened, his need for Rias escalating with every passionate movement. Their bodies moved together in a synchrony of desire and pleasure, creating an intoxicating rhythm that filled the room, a sensual symphony only they could compose.

Rias gasped with each penetration, her senses heightened by the mix of pleasure and the thrill of exploring new sensations. The slight discomfort had faded, giving way to an overwhelming surge of desire.

As Rudy filled her completely, her virgin pussy stretched and yielded, embracing the pleasure that coursed through her.

Rudy's breath hitched in his chest as he felt his big, throbbing length clasped between the tight walls of Rias' virgin pussy. The sensation was unlike anything he had ever experienced, a perfect fusion of pleasure and intensity that sent electric currents of desire surging through his veins.

Of course, he had opened the seal of many girls and it wasn't as though he felt different with Rias. But Rias was a vampire and her body was naturally more developed than the human girls.

Penetrating Rias for the first time reminded Rudy of the time he fucked Jane. However, Rudy and Jane had done a lot of foreplay before jumping into the main action.

Whereas, Rias didn't let Rudy focus on the foreplay and her pussy wasn't as wet as Jane's was when she lost her V card.

As Rias felt her pussy being filled by Rudy's rock-hard dick, her moans escaped from her mouth.

"So… this is how it feels… to be plugged in by a dick. I feel full… My stomach feels full. Is it that the main reason the girls have a puss is that the boys can plug their dicks in?"

"Sex is primarily for reproduction. But yes." Rudy shrugged his shoulders.

Rudy's thrusts quickened, his hips meeting Rias' body with a rhythm that mirrored their shared desire. With each passionate movement, he deepened the connection between them, their bodies moving in perfect harmony. As their lips remained locked in a fierce kiss, their tongues danced together in a passionate embrace, fueling the intensity of their lovemaking.

The room was filled with the sounds of their breathless moans, mingling with the sound of their bodies rubbing together. The air crackled with electricity as their pleasure grew, reaching new heights with every thrust. Rudy could feel the heat building within him, his body pulsating with an uncontrollable need to please Rias and bring her to the pinnacle of orgasm.

Rudy was truly surprised that Rias was able to hold off her orgasm for so long, but looking at her face, he realized that she was close.

Thus, he decided to make Rias' first orgasm with his dick, memorable.
