Sein climbed onto Andrey’s lap, her hips beginning a slow, deliberate grind against him. The thin fabric of her black lace panties was already soaked, and with each roll of her hips, the slick heat of her pussy pressed against his hard, throbbing cock. A low, breathy moan escaped her lips as the friction sent sparks of pleasure through her body.

"Nnh... you’re so hard..." she murmured, her voice husky with desire. "I can feel you twitching against me..."

Andrey’s hands gripped her hips, his fingers digging into her soft flesh as he guided her movements. The sensation of her wet panties sliding against his cock was maddening, the fabric clinging to her folds with every teasing motion. He could feel the heat of her, the dampness seeping through the lace, coating his length with her arousal.

"Sein... you’re soaking through your panties," he groaned, his voice rough. "You’re this wet just from rubbing against me?"

Sein’s cheeks flushed, but she didn’t stop. Her hips moved faster, grinding harder against him. "Shut up... it’s your fault... making me feel this way... ahh—!"

Lisa, still pressed against Andrey’s side, leaned in and began kissing his neck. Her lips were soft and warm, trailing slow, lingering kisses along his skin. Her tongue darted out, tracing the line of his jaw before she gently sucked on a sensitive spot just below his ear.

Andrey groaned, his head tilting to give her better access. "Lisa... your lips feel so good..."

Lisa smiled against his skin, her hand sliding up his chest to rest over his heart. "I want to make you feel good too, Andrey..."

Sein’s grinding grew more intense, her hips rolling in circles as she pressed herself harder against him. Her breath came in short, desperate gasps, her eyes half-lidded with pleasure. She leaned forward, capturing Andrey’s lips in a deep, hungry kiss.

The kiss was hot and demanding, Sein’s tongue pushing past his lips, exploring his mouth with a fierce, almost possessive passion. Andrey responded in kind, his tongue meeting hers, their kiss growing messier and more desperate.

Lisa continued kissing his neck, her hand sliding down to join Sein’s on his cock. Together, they stroked him in rhythm with Sein’s grinding, their movements coordinated and eager.

The combination of Sein’s slick grind, Lisa’s soft lips on his neck, and the dual sensation of their hands on his cock was overwhelming. Andrey broke the kiss, his breathing ragged, his head falling back against the couch.

"Fuck... you two are going to make me cum just from this..." he groaned.

Sein’s eyes gleamed with triumph, a satisfied smile curling her lips as she looked down at him, her grinding taking on a faster, more urgent rhythm. She wanted to feel his pleasure, to know she was driving him to the edge.

"That’s the plan," she said, her voice low and teasing. "We’re not stopping until you’ve given us everything."

Andrey’s breathing was ragged, his hands gripping Sein’s hips as she continued her teasing grind. The friction was maddening, her soaked panties sliding against his aching cock with every roll of her hips. He could feel the heat of her, the dampness seeping through the thin lace, and the need to be inside her was becoming unbearable.

"Sein... I want to be inside you," he said, his voice low and rough with desire. "I need to feel you..."

Sein’s eyes gleamed with a mixture of triumph and arousal. She slowed her grinding, a teasing smile curling her lips. "Oh? You want to be inside me?"

"Yeah...i want to feel you, Sein..." Andrey’s voice was strained, his control slipping with every passing second. "Let me feel you..."

Sein’s breath caught at his words. Her cheeks flushed deeper, a clear sign of her excitement. She hadn’t expected him to beg so earnestly, and the raw need in his voice sent a surge of heat straight to her core.

"...Good. I like hearing you beg," she said, her voice a little unsteady despite her teasing. "Now you’ll get what you want."

She shifted her hips, hooking her fingers under the waistband of her panties and pulling them to the side, exposing her slick, glistening folds. She reached down and guided his cock to her entrance, the head pressing against her wet heat.

Both of them gasped as the tip of his cock made contact with her slick, heated folds, a jolt of electric pleasure shooting through them. Sein’s eyes fluttered closed for a moment as she savored the sensation.

Then, slowly, she began to lower herself.

"Ahh..." she moaned softly, her body trembling as the thick head of his cock pushed past her entrance. "It’s... so big..."

Andrey groaned, his hands gripping her hips as he felt her tight walls envelop him. The sensation was incredible—her pussy was so warm and snug, stretching to accommodate him.

"You’re so tight... Sein..." he breathed, his voice strained with pleasure.

Sein’s breath hitched, a low, sensual moan spilling from her lips as she continued to sink down onto him, taking him deeper inch by inch. She could feel every vein, every ridge of his cock as it filled her, stretching her in the most delicious way. Her inner walls quivered, fluttering around his length as she adjusted to his size, the sensation so intense it made her thighs tremble.

"Nnh... you’re so deep inside me," she whimpered, her head falling back as she finally took him all the way, her hips flush against his.

Andrey groaned, his hands sliding up to grip her waist, his fingers digging into her soft flesh as he struggled to maintain control. "Sein... you feel so good..."

Lisa, still pressed against his side, let out a soft, encouraging moan. She continued kissing his neck, her lips warm and tender, while her hand stroked his chest, feeling the rapid beat of his heart beneath her palm.

Sein’s breath was already coming in short, uneven gasps, her body adjusting to the fullness of him inside her. She began to move, slowly at first, her hips rolling in a sensual rhythm that made her gasp with every motion. The feeling of his thick length sliding in and out of her was almost too much to bear.

"Ahh... you’re so deep..." she whimpered, her voice trembling with pleasure. "I can feel you... in the most private part of me..."

Andrey groaned, his hands moving to her thighs as he guided her movements. "You’re incredible, Sein..."

Sein’s movements grew faster, more urgent. Her moans grew louder, filling the room as she rode him with increasing desperation. The competition, the pleasure, the feeling of being so completely filled, was driving her wild.

"Don’t stop... don’t stop..." she gasped, her eyes half-lidded with pleasure. "I’m so close..."

Lisa pressed herself closer to Andrey’s side, her lips brushing against his ear as she whispered, "Cum for her, Andrey... let her feel all of it..."

Andrey groaned, his hips bucking up to meet Sein’s movements. "I’m going to cum..."

Sein’s eyes widened with excitement and need. "Yes... fill me up... I want to feel it all—!"

With a deep, guttural groan, Andrey thrust up one last time and came hard. Thick ropes of hot cum erupted deep inside her, flooding her womb. Sein cried out as she felt the warmth spreading through her, her pussy clenching tightly around him as she reached her own climax.

"Hyaaahn!! I’m cumming—!!"

Her body convulsed in his lap, waves of intense pleasure coursing through her as she rode out her orgasm. Andrey held her close, his breathing heavy as he emptied himself inside her.

When the waves of pleasure finally subsided, Sein collapsed against his chest, her body trembling with aftershocks. Lisa gently stroked her back, a soft smile on her face.

"That was... incredible..." Sein breathed, her voice hoarse and satisfied.

Andrey kissed the top of her head, his hands still resting on her hips. "You were amazing."

Sein let out a soft, contented hum, her body still pressed against him. She could feel his cock still twitching inside her, and the thought of more made her shiver with anticipation.

The System’s voice chimed in, its tone playful and teasing.

System: Oho~ That was a lovely performance!
