As Buffy walked into the library, wearing only a coat, Xander's eyes widened in surprise. But instead of pushing her away or trying to figure out what was wrong, he let his desire get the better of him. He had always had a crush on Buffy, and now she was throwing herself at him.

"Buffy, what's going on?" Xander asked, trying to sound casual despite the excitement in his voice.

But Buffy just smiled and walked closer to him, her eyes locked on his. "I don't know, Xander," she said, her voice husky. "I just feel like I need to be with you right now."

Xander's resolve crumbled, and he reached out to pull Buffy into his arms. They kissed, passionately, as the library around them faded into the background.

As they broke apart for air, Xander looked into Buffy's eyes, searching for any sign that she was still in control. But all he saw was desire and adoration, and he let himself get swept up in the moment.

Buffy let the coat slide off her shoulders, and it fell to the floor with a soft rustle. Underneath, she was completely naked, her breasts firm and perky, her nipples already hardening in anticipation. Her waist was narrow, flaring out into hips that seemed to be designed for pleasure.

As she stepped closer to Xander, her eyes never left his. She was ready for him, her body trembling with anticipation. Her pussy was already wet, the lips swollen and inviting.

Xander's cock hardened in response, straining against his pants as he reached out to touch her. Buffy's hands went to his belt, quickly undoing it and pulling down his zipper. She reached inside, her fingers wrapping around his cock, and pulled it out.

Her eyes never left his as she sank to her knees, her mouth opening to take him in. Xander groaned in pleasure as she wrapped her lips around his cock, her tongue swirling around the head. She was hungry for him, devouring him with a fierce abandon.

As she sucked him, Buffy's hands went to her own body, her fingers stroking her breasts and teasing her nipples. She was a vision of eroticism, her body trembling with pleasure as she worked Xander's cock.

Finally, she pulled back, her eyes flashing with desire. "I want you inside me," she whispered, her voice husky with need.

Xander didn't need to be told twice. He lifted her up, spinning her around to press her against the library table. Her legs went around his waist, pulling him closer as he positioned himself to take her.

As he thrust into her, Buffy's eyes went wide, her mouth opening in a silent scream of pleasure. She was ready for him, her body accepting him with a warm, wet welcome. Xander groaned in response, his cock sinking deep into her as they began to move together in a fierce, primal rhythm.

The sound of their bodies slapping together echoed through the library, a rhythmic beat that seemed to match the pounding of their hearts. The air was thick with the scent of sex and sweat, and the taste of Buffy's skin was sweet on Xander's lips.

Buffy's fingers dug into Xander's back, her nails scraping against his skin as she pulled him closer. Her breasts bounced with each thrust, the nipples rubbing against Xander's chest. Her mouth was open, her breath hot against Xander's ear, and her moans were like music to his ears.

Xander's hands were on Buffy's hips, holding her in place as he drove into her. He could feel the heat of her body, the warmth of her skin, and the tightness of her pussy as it gripped his cock. He was lost in the sensation, his mind consumed by the pleasure of being inside her.

As they fucked, the world around them melted away, leaving only the two of them, lost in the moment. The library, with its dusty books and quiet corners, was transformed into a place of primal passion, where the only thing that mattered was the pleasure they were giving each other.

Finally, after what seemed like an eternity, Xander felt himself reaching the edge. He thrust into Buffy one last time, and then he was coming, his cock pulsing with pleasure as he emptied himself into her. Buffy's body tightened around him, her muscles contracting as she came too, her moans rising to a crescendo as they both reached the peak of their pleasure.

As they collapsed against each other, the spell that had driven Buffy to seduce Xander began to wear off. She looked up at him, confusion in her eyes, and Xander knew that she had no memory of what had just happened. He smiled to himself, feeling a mix of guilt and pleasure. He had taken advantage of the situation, and he knew it. But he couldn't help the way he felt. He had wanted Buffy for so long, and now he had her, even if it was just for a moment.

Buffy looked around, taking in the library and the coat that lay on the floor. She seemed to be trying to remember something, but it was clear that she had no idea what had just happened. Xander decided to keep it to himself, to enjoy the memory of their encounter without telling her about it. He helped her up, and they both got dressed, the silence between them awkward but unspoken.

As they left the library, Xander couldn't help but feel a sense of satisfaction. He had gotten what he wanted, even if it was just for a moment. And he knew that he would never forget the way Buffy had felt, the way she had tasted, and the way she had sounded as they made love. The memory of their encounter would stay with him forever, a secret pleasure that he would savor in the days to come.
