The Omnistore System

Chapter 390: Nipple Tactics (R-18)

Key nodded, not fully understanding what he meant, but still eager to comply. She began to move her hips slightly, but Kevin's firm grip stopped her movement. Confused, she looked up at him with a questioning expression. With a smirk, he said, "Your pussy walls, not your hips."

"How?" she asked, feeling a bit frustrated as her desire for another orgasm grew stronger. Kevin, still smirking, reached down and pinched her nipples, causing her to gasp and moan, her body instinctively responding as her vaginal walls tightened around him.

"Like this," he said with a grin, his eyes glinting with mischief.

Key looked at him with a mix of anger and frustration. Her body was flushed, her skin glistening with a sheen of sweat. Her breasts, firm and supple, heaved with her heavy breathing, the nipples hard and sensitive under his touch. She could feel her arousal building, her need for release growing more intense by the second.

"Why? I can do it with my hand," she said, her voice tinged with impatience. She blushed deeply, the pink hue spreading across her cheeks and down her neck. "Or my mouth..." she added, her voice softer, more hesitant.

"If you want to use your mouth, you can do that next time. For now, just use your pussy's insides to do the deed. Unless you want to stop?" Kevin said with an evil smirk.

"You're so mean and evil," Key said in a frustrated, childish tone. She truly meant it. She had met Riya many times and knew Kevin's sister was easy to manipulate because of her kindness. Both she and Natalie had assumed Kevin would be the same, but their guess was wrong as she faced Kevin's wicked smile.

Kevin just smirked at her words. Key didn't care anymore if he was mean or stubborn; the only thing on her mind now was the soft penis inside her. He had tasked her with making it hard using only her vaginal walls and had even shown her how.

Seeing that he wasn't budging from his decision, she, with a frustrated expression, reached to squeeze her breasts as Kevin held her from behind in the spooning position.

Kevin's smirk deepened as he watched Key's determination take over. She squeezed her breasts, her fingers pinching and kneading the soft flesh, causing subtle movements in her body. These movements sent ripples through her vaginal walls, which clenched around Kevin's penis, squeezing and massaging it.

Her breaths quickened, and Kevin could feel the gradual effect of her efforts. His penis started to respond, growing harder within her. Key's frustration began to transform into concentration as she focused on using her breasts to create the right rhythm. Each squeeze of her breasts caused her vaginal walls to tighten and release, bringing him closer to full arousal.

As she continued, her own arousal built up, making her efforts more intense. Kevin could feel her walls contracting more frequently, the pressure increasing around his shaft. Key's cheeks flushed, a mix of determination and desire in her eyes. She bit her lip, trying to maintain her composure, but the pleasure was becoming overwhelming.

Kevin, feeling her efforts paying off, leaned in to whisper in her ear, "That's it, Key. Keep going. You're doing great."

He kissed her sweaty cheeks and lips, causing her already breathless state to intensify. Trembling, she reached down, grasping her own nipples. The skin around them reddened as she squeezed, pulled, and rubbed them. With a final, strong squeeze of both nipples, her vagina spasmed, releasing her orgasm.

In Kevin's embrace, her body convulsed. She felt embarrassed for climaxing while touching herself despite his penis being inside her vagina. It made her feel as though she had become a pervert. Sensing Kevin looking down at her as she orgasmed only heightened the intensity further.

As she continued to play with her buds, Key could feel Kevin's penis responding inside her, swelling and filling her once again. It was exactly what she had intended from the start-to arouse him further, to feel him grow inside her, and to revel in the raw, primal connection between them.

Despite the intense and somewhat shameful pleasure of bringing herself to orgasm while he was still inside her, she persisted. Her determination mingled with a desperate hunger for make his penis hard. With each deliberate squeeze and release of her vaginal muscles, she aimed to replicate the rhythmic pleasure of a blowjob.

Her actions were a mix of desperation and arousal, a primal urge driving her to seek more sensation. With each pinch and pull, she elicited soft moans that escaped her lips, her eyes tightly shut in blissful surrender. The reddened peaks of her nipples stood out against her fair skin, hardened and begging for attention.

As her hard work finally bore fruit, Kevin whispered in a low tone into her ears, "Congratulations, you made it hard..."

Key let out a sigh of relief upon hearing this, her body growing limp as she exhaled deeply. She had been controlling her breath before to avoid another orgasm, but now that she had succeeded in making his penis hard, she could finally reap the rewards of her efforts. "I did it," she whispered to herself, a satisfied smile spreading across her face. Now, she anticipated more orgasms from his hard penis.

However, all her exertion had left her body weak, and she felt uncertain whether she could withstand Kevin's thrusts now, having already orgasmed four times. But a determined smile played on her lips. 'I don't care,' she said to herself, looking at Kevin with a wide smile. "Now, fill me up again..."

Kevin heard her and smirked, adjusting their position. He made her lie on her stomach and then positioned himself on top of her, his penis still inside her. He moved swiftly, but Key wasn't surprised; she maintained her smile, burying her face into a pillow and clutching it tightly. He also slid one pillow under her hips to keep them up and then, leaning forward, he pulled her head back by grabbing her to look at him and ordered. "Keep your ass up."
