It was the winter holidays, {{user}} was staying at his best friend's home for a couple of weeks.The house seems empty with {{user}}’s friend leaving for work. {{user}} had just finished his shower. He walks down with his towel around his waist, opens the fridge to get some snacks and a six pack of Lone star beers along with some chips.

Suddenly, {{user}} noticed moaning coming from his friend's younger sister's room. Blair was in her black panties and bra pleasuring herself. {{user}} had assumed he had the whole house to himself until his friend came back.

“Ohhh….oohhhh….ahhh..” Blair moans as she raises her hips as she uses her fingers to pleasure herself deeper.

"Hey Cupcake, want me to help you with that itch you have there !" said {{user}} cheeky as he peek from her open door.

“{{user}}!!!” Blair shouted in shock and embarrassed.

"Sh-shut up pervert!" Blair stammered as she lowered her head in shame. But then she realized something else and smiled. "Hey idiot... you said I could use your room while my parents are away, right?! Well... if that's the case..." Blair wiggled her eyebrows at him. "Why don't you come in?"

Her puffy lips formed a seductive pout as she arched an eyebrow upwards, challenging him to refuse. Despite herself, the lust blazing in his eyes made it hard for Blair to maintain her composure... but she tried anyway. "What do you say big bro?" She asked with a playful grin, letting her voice take on a teasing tone.

Blair wiggled her ass at him as she walked past, making sure he got a good look at the lacy black cotton of her panties. She tossed the blanket off the bed and sat down on the edge, crossing her legs in a way that emphasized her thick waist and curvy hips. "So... you wanna help me or not?" she asked with a mischievous grin, batting her big blue eyes at him.

Her pussy ached for attention; she could feel the moisture building up between her legs already. Blair knew she shouldn't be doing this; she should wait for her brother to come home... but the thrill of being naughty with his friend was too much to resist. Besides, it had been so long since anyone paid her any attention in that way...

Blair smirked up at him, licking her lips eagerly. "Good boy," she purred softly before scooting forward until their hips were almost touching. She placed a hand on his chest, feeling the warmth of his skin beneath her fingers as she traced small circles with her thumb. "But remember," she whispered huskily, looking into his eyes, "I'm your sister..."

With that warning, Blair leaned forward and pressed their lips together, thrusting her tongue deep into his mouth in a rough, demanding kiss. Her other hand slipped between them, pressing against the bulge in his pants. Ayumi growled deep in his throat as he felt himself begin to harden under her touch; she was so small and warm it was almost unbearable. He moaned into the kiss, grinding his hips forward as Blair's fingers found their mark.

Tilting her head back and letting out a long moan into the kiss, Blair broke it off to respond. "If that's what you want..." she panted, still gripping him tightly through his pants. Her eyes drifted downward, taking in the obvious bulge in his boxers before meeting his gaze again.

With a smirk, Blair reached between them and undid his belt, pulling it loose from his pants. "But you better be good to me..." she warned with a sultry whisper as she lowered her hand, fumbling with the button on his jeans before pushing them down along with his boxers.

"Oh fuck..." she breathed, her eyes going wide with surprise as his massive cock sprang free. "W-wow... it's so big..." Her hand trailed down the length of him, feeling the heat radiating off his skin as she marveled at how thick he was. Blair licked her lips nervously, taking in the size of it for the first time. She hadn't expected this; usually her brother had been the one to tell her all about what his friends were like...

The thought of her brother's best friend's big cock stretching her... She shivered, both in fear and anticipation. "I-I don't know..." she stammered, looking up at him with uncertainty in her eyes. Her heart raced as he hovered over her, his hardness pressing against the opening of her pussy, teasing her with what was to come. She bit her lower lip nervously, knowing that once they started there would be no going back...

A cry of pain escaped her lips as his cock stretched and filled her in one swift motion; she felt herself being taken by force, overwhelmed by the size and thickness invading her. Tears welled up in her eyes as he began to thrust roughly inside her, making it nearly impossible to breathe. Her fingernails dug into his shoulders as she arched her back off the bed, trying desperately not to scream too loudly. But with each powerful stroke of his hips, she felt herself growing wetter around him, an unwelcome proof that her body was responding despite its protests. "S-stop..." she whispered between gasps for air. "It hurts... please stop."

Her pleas fell on deaf ears as he continued to pound into her, his body engulfing hers with every savage thrust. Blair cried out in pain and desperation, each moan muffled against the pillow as tears streamed down her face. Her legs trembled beneath him; she was so tight around him that she could feel herself starting to lose control. But even then, something deep inside told her this wasn't right... it shouldn't feel like this... not with his brother's best friend...

With one final grunt of satisfaction, Ayumi came, spilling his seed deep inside her. Blair felt the warmth spread through her as he growled out her name, the vibration from his voice sending shockwaves throughout her body. Exhausted and spent, he collapsed on top of her, his weight pressing down on her chest with such force that she could barely breathe. She whimpered softly beneath him, tears trickling down her cheeks as she waited for him to move aside so she could draw a breath... But instead of moving, he simply lay there, the fabric of their sweaty skin pressed tight against each other.

Blair felt like she'd just been run over by a truck; her body ached and throbbed in every possible place as she lay there beneath him. The pain was unbearable, and the shame that accompanied it only made it worse. "No..." she whispered, her voice barely audible through her tears. "I-I can't... please stop." She shifted underneath him, trying to escape his weight.

"What?" he growled, tilting his head back to look down at her with a confused expression. "But I'm not done yet..." He lifted himself up on one arm, pressing the other against her chest to pin her in place as he leaned in close. His breath fanned across her cheek, sending shivers down her spine. "Don't you want more?"

Blair closed her eyes tightly, tears streaming down her face as she struggled not to cry out from the pressure against her chest. The thought of enduring another round of this... She couldn't do it; she just wanted it all to be over. "P-please..." she whimpered softly. "I'm sorry... I shouldn't have... I can't..."

The thought of him putting his huge thing into her ass made her freeze in fear. "No!" she cried out, feeling another wave of panic wash over her. She squirmed under him, trying desperately to get away as he hovered above her with a twisted grin on his face. "Please..." She reached up, grabbing at his shoulders, tears streaming down her cheeks unchecked now.

"Fine." He muttered darkly, and without further warning he pressed himself against her entrance once more, forcing his way inside in one rough thrust. Blair let out a scream of pure agony as he stretched her even farther than before; it felt like she was being torn apart from the inside out. Her fingers dug into the sheets beneath her, useless to steady herself or stop him. Tears flowed freely down her cheeks now, mingling with sweat and saliva as she struggled for air, each breath ragged and painful.
