Chapter Four: Guilty

•••••

Prue was lying with her head tucked into the nook of Gavin's neck. She inhaled deeply and soaked up the smell of his cologne. Mmm, he smells so good. She noticed a hand on her waist. He was gently stroking her hipbone. She sighed and kissed his neck softly. He smiled nervously.

"What?" She asked after she noticed his reaction.

"Tickles." She smiled. "So when does Phoebe get home?"

At the mention of her sister, Prue's mind went blank. Phoebe. Her sister. Gavin's girlfriend. Oh shit. Oh shit. Nooo. Nonononooo. She quickly pulled away from Gavin and sat up in bed. Clinging the sheets to her body, she dragged herself out of the bed and walked over towards her closet.

"Prue?" Gavin's voice brought her back to the physical world. "Prue? What's wrong?" He stood up naked and approached her. Her eyes darted around the room as he wrapped his arms around her shaking frame. Quickly she pulled away with him.

Tearfully, she looked him in the eye and quietly said, "No. Stay away from me."

"Prue, what's going on?" Gavin asked with concern laced in his voice.

"Do you know what we just did?" She asked, her voice barely a whisper.

"We had sex. People do it everyday. It's no big deal."

"No. What we did to Phoebe. We just completely fucked everything up. Everything." She blinked back the tears and turned away from him. She reached into her closet and pulled out her bathrobe. She wrapped it around her as she dropped the sheets. He smiled as he saw a flash of her bare body. He walked up behind her again and wrapped his arms around her waist. One of his hands managed to sneak into her robe. She felt his warm fingers slide across the flesh on her stomach and up to graze over her breast. Her breathing was ragged as she pulled away from him again.

"Stop it," He caught a flash of anger in her eyes.

"Why?"

"Because this entire thing was wrong. We should never have-"

"What? Given in to what we knew was going to happen eventually? Prue, stop denying it. We have chemistry. It's something I haven't had with anyone in a long time. We belong together." He paused to take in a deep breath and sighed.

"Phoebe and I, we're good together. We get along, have good conversation, pretty decent sex." Prue shifted uncomfortably at the mention of her little sister sleeping with the same man that stood naked in front of her. "But, you and me? We click. You can't say that what just happened here wasn't great for you." She opened her mouth to protest, but he continued. "I heard your moans. And your screams. They were screams of passion. I know they meant something. I love what just happened. I want us to be together. Prue," He took in another deep breath. "I love you." Those three words pulled her out of her daydream of a life with Gavin and back into the real situation where she knew she would wind up Gavin-less.

"You love me?" She smiled at this comment. Quickly her expression turned to one of anger. "If you really loved me, you wouldn't have just hurt my sister like you did. There's no chance of us ever being together after this. None." He didn't respond.

"You don't honestly think that this is going to blow over with Phoebe and then we can finally be together, do you?" She said with anger rising in her voice.

"Now, Prue, calm down." He said as he noticed her white knuckles.

"Don't tell me to calm down. Do you know what we just did? Do you know how much it'll hurt Phoebe when she finds out?" Prue felt her own heart shatter into a million pieces as she thought of Phoebe's reaction. What the hell was I thinking?

"Who says she has to find out?" He smirked and raised his eyebrows. "This could just be our little secret." He added, shrugging his shoulders.

"What? No! I have to tell her." Prue said, fighting her own desires to kiss him. She wanted to feel his bare skin against hers. She wanted to feel him leave trails of kisses along her waistline. She wanted him to make love to her again. No. I can't sleep with him again because then it would be even worse. The farther we get from each other, the better.

"Why?" He asked as she bent over and picked up the pile of sheets lying at her feet. She threw them in her closet and turned her attention back to an expectant Gavin.

"Because I can't let her continue going out with you." She said as she started gathering Gavin's discarded clothes.

"Even if it means losing a sister?" Thinking he had her cornered, he smiled.

"Yes." She paused as she took in a ragged breath. "I know what I just did will hurt her. But if you two keep dating, and you cheat on her somewhere down the line, it will destroy her. I couldn't live with myself if I knew I could have prevented that. What pain she might feel now could be far worse in the future. Unless it's over between you two."

"But, Prue, she'll hate you if you tell her." He smiled again.

"I know. But I deserve it." She paused as she gathered up the last of Gavin's clothes. "And so do you." She threw them at him. "I don't want you to call her. I don't want you to see her. Ever. Now get out of here before she gets home," she said coldly. He didn't move. "Get out now." She added in a harsher tone before spinning around and heading out the door.

As she walked down the hallway, tears started forming in her eyes. She went into the bathroom, and locked the door behind her. As she collapsed on the floor, silent tears began to fall.

She heard Gavin walk down the stairs. The tears multiplied. She heard him open and shut the front door. She let a few audible sobs slip out. A thought crossed her mind. One she hadn't thought of since she was seventeen. Quickly, she pushed it out of her mind. But as the minutes flew by, she knew there was nothing else she could do. It had helped her before, it can help her through this now. She had no other option.
