Not yet. Gonna draw this out for hours.

As Lisa neared the precipice of orgasm, her breath hitching and her body tensing, Aiko noticed the subtle shift in her lover's demeanor. The futanari smirked, a wicked glint in her eye, and deliberately slowed her pace. Lisa let out a frustrated moan, her hips bucking in a silent plea for more.

"Patience, Lisa," Aiko purred, her voice a low growl that sent shivers down Lisa's spine. "I want to savor you."

With that, Aiko began to thrust with excruciating slowness, pulling almost all the way out before plunging back in with a **** that made them both cry out. The rhythm was maddening, a sweet **** that left Lisa teetering on the edge of ecstasy.

Aiko drew back for a second time. This time as she thrust forward she leaned down, capturing Lisa's lips in a fierce kiss. As her cock went deep in Lisa's pussy their moans intertwined, lost in the wet heat of their mouths as they french kissed with an intensity that matched the slow, deep strokes of Aiko's cock inside Lisa's pussy.

This dance of pleasure continued for hours, the two women locked in a passionate embrace that seemed to transcend time. Aiko would start to speed up, the slapping of their skin echoing in the room, only to slow down again, maintaining a rhythm that was agonizingly slow yet filled with an undeniable urgency.

As they moved together, Lisa could feel every inch of Aiko's impressive length, the thick shaft rubbing against her sensitive walls, coaxing her closer and closer to the edge. Aiko's hands roamed Lisa's body, cupping her breasts, teasing her nipples into hard peaks, and then sliding down to grip her hips, pulling her into each thrust with a strength that left Lisa breathless.

Lisa's own hands were not idle, exploring the contours of Aiko's muscular back, her fingers digging into the firm flesh as she met each of Aiko's thrusts with equal fervor. Their bodies were slick with sweat, sliding against each other in a rhythm as old as time.

For hours, they continued like this, Lisa's whimpers grew more ****, her need for release becoming a physical ache. "Aiko, please, I can't take it anymore. I need to come." Aiko's eyes darkened with lust, her own need finally matching Lisa's. With a moan she pulled out of Lisa and lie on her back. "Show me how much you want it," she commanded.

With an eagerness that seemed to totally forget that Lisa originally had been against this, Lisa straddled Aiko, positioning herself above the thick cock that had been tormenting her so deliciously. She lowered herself onto it, her pussy already stretched and ready from hours of earlier fucking. She began to ride Aiko with abandon, her hips undulating in a primal rhythm that spoke of raw, unadulterated need. Each thrust drove Aiko deeper into her core, the friction sending sparks of pleasure radiating throughout her body. Lisa's breasts bounced with each movement, her nipples hardened peaks that begged for attention.

Aiko was more than happy to oblige. She leaned forward, capturing one of Lisa's nipples between her lips and sucking deeply. The sensation was electric, and Lisa cried out, her walls clenching around Aiko's shaft.

The sound of their flesh meeting in a dance as old as time filled the bedroom, a testament to their lust. Lisa's moans grew louder, a symphony of pleasure that echoed off the walls. Aiko, ever the dominant ****, was not about to let them be discovered.

In one swift motion, Aiko pulled Lisa's face down to hers, their lips crashing together in a passionate kiss that muffled Lisa's cries of ecstasy. "Quiet," Aiko murmured against Lisa's mouth, her voice a husky whisper that sent shivers down Lisa's spine. "We don't want to wake my mom and little sister right?"

Lisa shook her head, her eyes wide with a mix of fear and excitement. She quickened her pace, the need to stifle her moans only adding to the intensity of her arousal. Their tongues danced together, licking and tasting as they devoured each other's mouths.

Aiko's hands gripped Lisa's hips, guiding her movements with an iron grip that left no doubt as to who was in control. Lisa's body was on fire, her climax building with each punishing thrust. She could feel Aiko's cock twitching inside her, a clear sign that the futanari was close to her own release.

Their bodies moved as one, a symphony of lust and desire that crescendoed with each passing moment. Lisa's walls fluttered around Aiko's length, the sensation driving them both to the brink of insanity.

With a final, powerful thrust, they tumbled over the edge together. Lisa's orgasm crashed over her like a wave, her pussy clamping down on Aiko's cock as she rode out the pleasure. Aiko followed suit, her hot release flooding Lisa's womb as they both cried out into each other's mouths, their voices louder than they should have been.

For a moment, they remained locked together, their bodies slick with sweat and their breaths coming in ragged gasps. Slowly, Lisa lifted herself off Aiko's softening length, a mixture of their fluids trickling down her thighs.

Aiko lay back, a satisfied smirk playing on her lips as she watched Lisa try to regain her composure. The blonde hair was a mess, her cheeks flushed with the afterglow of her orgasm. Aiko reached out and traced a finger along Lisa's jawline, her touch gentle despite the roughness of their encounter.

"You were incredible," Aiko purred, her voice filled with genuine admiration.

Lisa blushed, a shy smile tugging at the corners of her mouth. "So were you," she replied, her voice barely above a whisper.

They lay there in silence. Lisa was thinking about how never in a million years would she thought she was going to fuck her best friend's older sister tonight, but she had done it, and she had loved it. She reflected more and her and Aiko fell asleep side by side.
