Sein’s aggression intensified. She pressed her body flush against his, her hands sliding under his shirt, pushing it up roughly. Her mouth found his neck, licking a hot, desperate trail down to his collarbone. When she reached his chest, she latched onto one of his nipples, sucking hard, her tongue swirling with hungry need.

Andrey groaned sharply, his body jerking at the sudden intense sensation. "Sein... fuck..."

The feeling of her warm, wet tongue on his nipple sent a raw bolt of pleasure through him. His usual calm shattered. He grabbed the hem of her black tank top and yanked it upward, exposing the tight sports bra underneath.

Sein gasped, her body tensing. "Andrey— wait... I’m still sweaty from the jogging... don’t—"

But Andrey didn’t wait. His fingers hooked under the hem of her sports bra, pulling it up roughly over her breasts, letting them spring free. Before Sein could gasp out another protest, he was already leaning down. His mouth closed around one of her nipples, sucking firmly, his tongue dragging across the sensitive peak. Sein’s back arched sharply, a broken, feminine moan tearing from her throat.

"Anh—!! Andrey... you idiot... ahhn—!! I told you not to lick there... it’s dirty... nhaa—!!"

Her voice trembled with embarrassment and unwanted pleasure. She tried to push his head away, but her fingers only tangled in his hair, pulling him closer instead.

Andrey didn’t stop. He sucked harder, licking every inch of her breast, tasting the faint salt of her sweat. His other hand cupped her other breast, squeezing it possessively as his thumb brushed over the stiff nipple.

Sein’s breath hitched, her body betraying her. "You... you’re really not listening... ahhn... Why does it feel so good when you do that...?"

Andrey pulled back just enough to look at her, his voice low and rough. "Because I want you."

Sein’s eyes widened, a flash of vulnerability crossing her face before she tried to hide it with a shaky glare. "Don’t say stupid things like that... ahhn—!!"

Andrey’s mouth continued its relentless exploration of Sein’s breasts. His tongue dragged slowly across her skin, tasting the faint sheen of sweat that still clung to her from the intense battle earlier. The salty, slightly bitter flavor mixed with her natural scent filled his mouth as he sucked harder on her stiff nipple.

’Sein’s sweat... it’s salty, a little sharp, but warm. It’s strangely... addictive.’

The realization only fueled him further. He licked broader, slower strokes across the underside of her breast, savoring the warmth and the faint tang of her exertion, before moving to her other nipple. He sucked it deeply into his mouth, his tongue swirling around the sensitive peak while his hand kneaded the first breast firmly.

Sein’s body jerked violently. A sharp, feminine moan tore from her throat as she tried to hold onto her pride.

"Anh—!! Andrey... you’re really licking my sweat... ahhn—!! That’s... so embarrassing... don’t... nhaa~!!"

Her hands tightened in his hair, torn between pushing him away and pulling him closer. Her usual sharp, arrogant tone had completely melted into soft, needy whimpers. Her thighs trembled, pressing against his sides as pleasure overwhelmed her.

Andrey didn’t stop. He continued licking and sucking, his tongue exploring every curve of her breasts, tasting the mixture of sweat and her skin. The more he savored it, the harder his cock throbbed against her thigh.

Sein’s moans grew sweeter, more desperate. "You idiot... ahhn... why does it feel so good when you lick me like that... hyann—!!"

Andrey finally pulled back slightly, his lips glistening, his eyes dark with lust as he looked at her flushed, heaving chest. Sein stared back at him, breathing hard, her green eyes hazy with a mix of embarrassment and overwhelming arousal.

"You... you really are a pervert..." she whispered, her voice shaky, but there was no real anger in it, only raw, trembling surrender.

Andrey’s hand slid down her body, fingers brushing over her stomach before reaching between her legs. He stroked her soaked pussy slowly, feeling how wet she still was.

Sein gasped, her hips twitching. "Anh...! Andrey... wait... I’m still sensitive... ahhn—!!"

But she didn’t push him away. Instead, her legs parted slightly, inviting him further as her body betrayed her words once again.

Andrey’s desire had completely taken over. He cupped Sein’s face with both hands and pulled her into a deep, hungry kiss. Their lips crashed together with raw intensity. The kiss was messy, passionate, and full of pent-up lust, tongues sliding and tangling aggressively, saliva mixing between them.

The wet, obscene sounds of their kissing filled the small bathroom, soft, slick, and desperate. Sein moaned into his mouth, her hands gripping his shoulders tightly as she kissed him back with equal hunger. Her tongue fought against his, pushing, teasing, and surrendering all at once.

Andrey tilted his head, deepening the kiss even more. He sucked on her lower lip, then pushed his tongue back into her mouth, exploring her with dominant need. Sein whimpered, her body pressing harder against his as the kiss grew sloppier, wetter, more intense.

The sound of their lips smacking and tongues moving together echoed softly in the tiled room, lewd, passionate, and completely unrestrained.

Sein pulled back just enough to gasp for air, a thin string of saliva connecting their lips. Her voice was breathless and shaky.

"Andrey... you’re kissing me so hard... ahhn..."

But Andrey didn’t let her finish. He captured her mouth again, kissing her even more aggressively. His tongue dominated hers, tasting every inch of her mouth as his hands roamed down her body, squeezing her breasts and sliding lower to grip her ass.

Sein moaned loudly into the kiss, her body trembling against him. The wet, filthy sounds of their making out continued, lips sucking, tongues sliding, saliva dripping slightly from the corner of her mouth.

Andrey finally broke the kiss with a heavy breath, their faces still inches apart, lips swollen and glistening.

Sein stared at him, her green eyes dark with lust and a hint of vulnerability. Her chest heaved, her voice barely a whisper.

"You... you’re really not holding back today..."
