[This is my first time writing an R18, so it may not be very good. I tried though:)]
Later that night, in front of Kurenai's apartment they stood there for a while. As they stood there Kurenai seemed to have made her mind.
"Would you…like to drink something?" She asked with a nervous look on her face as she invited him.
Kakashi was surprised and looked at her nervous yet expectant look Kakashi chuckled and accepted with a smile on his face.
"Sure, I'm a little thirsty." He spoke as he grabbed her hand and gave her a light squeeze.
As Kakashi grabbed her hand, she seemed to calm down and invited him inside.
As they entered Kakashi saw a spacious and cozy apartment. It was nice and calming.
They stood in silence for a while, both didn't speak for some second making the atmosphere kinda awkward.
Then Kakashi moved closer. Kurenai didn't move away. She felt the warmth of his body as he reached out, brushing a strand of hair from her face.
"You are beautiful," he murmured as he stroked her cheek.
"Thank you," She mumbled in a low voice as she felt his touch.
His hand lingered on her cheek. He didn't pull away. But leaned in. And she didn't stop him when he leaned in.
His kiss was soft at first.
When she responded, his arm circled her waist, pulling her against him.
The fabric of his vest pressed against her chest, his body solid and warm.
Kurenai's hands slid up his chest, feeling the muscles hidden beneath layers of clothing.
As their kissing got deeper. His hands roamed her back, then lower, firm but not forceful. Kurenai arched into him, breath catching as his lips found the line of her jaw, then her neck.
They moved together, unhurried, like they had all the time in the world.
Kurenai led him toward her bedroom, fingers intertwined with his. When she looked back, he was already watching her, eyes dark with something deeper than just want.
Their lips met again the moment they crossed the threshold of her bedroom. Kakashi's hands slipped under the hem of her robe, fortunately for him she wasn't wearing her usual outfit.
The fabric parted easily as his fingers found the bare skin of her waist. He moved slowly, deliberately, savoring every inch.
Kurenai pressed against him, her hands sliding beneath his shirt to trace his lean, muscular torso.
He kissed her again, deeper, hungrier this time. Her robe slipped off her shoulders, pooling at her feet.
Kakashi stepped back slightly, letting his eye trace the curve of her body in the moonlight, the red of her eyes glowing softly as she now had forgotten all previous shame.
She reached for him, tugging at his vest until he shrugged it off, then helped him pull the rest away his undershirt, his forehead protector, and discarded all completely.
Kurenai pushed him gently back onto the bed, straddling his hips as her hands ran over his chest. She leaned down to kiss him, letting her body press against his, breasts brushing his bare skin, her heat already pulsing between her thighs.
Kakashi's hands moved to her hips, guiding her as she began to awkwardly move her body against him, slow and teasing.
Not being able to endure the heat Kakashi flipped her on her back and trailed kisses along her neck and his tongue flicked over her breast.
Kakashi knelt between Kurenai's thighs, his hands spreading her gently. His mouth pressed against her, tongue slow and teasing.
She gasped, fingers tangling in his hair as he worked, steady and focused, making her tremble with every careful stroke. After teasing her for a while he stopped as he moved her legs.
Kakashi guided himself into her slowly, as she gasped at the sheer size that was slowly stretching her. Her body tensed, and she took a breath as he filled her. A thin trail of blood marked the sheets. He was her first, and now she was his.
As he was fully inside her they both gasped, at the sudden heat, the perfect fit, and the way her body welcomed him in full.
He moved slowly at first, his hips rocking in a gentle rhythm, letting her feel everything. His hands gripped her thighs, jaw clenched as he tried to hold back, to savor every second.
He sat her up suddenly, arms wrapping around her back, his mouth finding her breast, as his tongue flicked over her nipple as she moaned softly into his hair. Their rhythm grew faster, more desperate. Bodies tangled, sweat-slick and breathless.
"Kakashi," she gasped, nails digging into his shoulders as the pressure built.
He grunted her name in return, thrusting up into her now, matching her pace, as was lost in her. The tension snapped moments later as her climax shuddered through her, and he followed right after, groaning into her skin as he spilled deep inside.
The room fell into a heavy stillness, their breathing the only sound beneath the faint rustle of the bedsheets.
Kurenai lay there, her face full of satisfaction but suddenly Kakashi rolled over her, his body pressing against hers.
She gasped softly as his hand gripped her thigh, spreading her legs again with a slow, possessive motion. He kissed her this time with more control mouth firm, tongue sliding against hers in a deep, unhurried kiss that made her toes curl.
Kakashi moved lower, lips dragging down her neck, over her collarbone, until he was between her legs. She let her head fall back, a soft moan escaping as his fingers inserted inside her, slow and focused. His movements made her hips lift toward him, breathing hard.
