Amber Ray lay in her bed thinking about the events that had happened in the past few months. She had "blossomed". She had gone from being a 90 pound, 5 foot tall, A-cup, waif into a shapely young woman. She was now at least 3 inches taller, weighed over 110 pounds and her breasts strained at the B-cup bras that she wore.
Even stranger than her physical transformation was her sexual one. She was sexually active and felt that she just couldn't get enough of it. Her first had been her brother, Bobby, with whom she had fallen in love. Then his twin, her other brother, Billy had "forced" her. She now admitted to herself that she had secretly wanted it and she had been unbelievably excited when he had just taken what he wanted from her. That thought still excited her! Then there was Dave, her boyfriend. She wasn't really serious about him, she told herself. But he was good in bed, though not nearly as exciting as her brothers.
All this had created a moral dilemma for Amber. She had always been the only one in the family to care about going to church and trying to live a moral life. She still felt compelled to read her Bible regularly and to attend church, and she often had guilt pangs about what she was doing. She rationalized her behavior in any number of ways. She told herself that she had been repressed because she had been "ugly" and that when she started filling out and getting prettier that she was naturally starved for attention. She reasoned that she would find a good man, settle down, and she would have a normal sex life with her husband. All this would be in the past. She knew, however, that her recent behavior went against what she truly believed. She was violating her conscience each and every time she had sex. Now that she had experienced it, though, she knew that she wouldn't turn back. Not yet.
Amber was in her second semester of college now. She looked forward to the times that she could be alone with Bobby. She still considered him to be her one true love. The problem was that Bobby had made it clear that he was going to play the field and, although he hated to hurt Amber's feelings and he truly did love her, there was no future between them. Not as lovers. Still, if they got the chance to be alone, they had sex. They made no excuses. They knew they were going to do it when they were alone. It was loving and passionate and fulfilling.
Then there was Billy. Sex with Billy was a totally different thing, altogether. In Amber's mind, Bobby made love and Billy fucked. She kept telling herself that she was going to put a stop to it, but when she got really horny, Billy was the one she thought about. She knew that there must be something a bit off in her mind to enjoy the things he did; especially the way he had, initially, "forced" her to do his bidding. In reality, she was eager for it. It excited her beyond all reason. When they made up their schedules for the semester, they compared, and without saying so, they made sure that that neither of them had classes on Thursday afternoons. Of course they knew that their brother, Bobby, did have classes at that time. And their Mother was working every day.
A couple of weeks into the semester, Amber was driving home on a Thursday, just after noon. She had gone through a drive-through to get a burger because she was anxious to get home. She knew what was going to happen. The same thing that had happened almost every week last semester and which had happened the previous week on Thursday afternoon -- she and Billy would fuck! She tried not to think about it too much. She didn't like to plan what she would do with him. She wanted to pretend to herself that it wouldn't happen; that she would find the strength to tell him that they had to end it. Yes, that's what she would do. Besides, she had tons of school work to do.
As she walked in the front door to the living room, she didn't see Billy anywhere. Maybe he was upstairs studying or taking a nap. She would take a nap herself, then study. She wouldn't even bother Billy.
Climbing the stairs, she noticed that the door to the twins' room was shut. Good. She went into her room quietly, closed the door, and then began to undress. She left her panties on and got under the sheet for a nap. She decided that she could sleep for an hour or so, then study.
Just as she was beginning to doze, her door opened and Billy demanded, "What the hell do you think you're doing?"
She reluctantly opened her eyes. "Taking a nap. I'm sleepy and I have a lot of studying..." She noticed that Billy was in boxer briefs and that his cock seemed to be hardening already. She wished that he was naked so she could see it.
Billy laughed. "You can nap anytime. I have needs."
"Needs? Get a girlfriend. We have to stop this, Billy. Be reasonable. This isn't right."
"Get up and take a shower," he suggested, with a leer.
"I took a shower this morning. Besides, I've decided that I don't want to do that anymore," she replied, even as she felt herself becoming aroused at the prospect.
"I'm gonna eat that thing, and I want it clean," he grinned.
Amber knew then that she couldn't resist him. He had done oral sex on her before and he was, undoubtedly, the master. He was so hungry for it that he was like a wild animal. It was amazing and she knew that she couldn't turn it down.
"Billy! Don't talk that way. There's no need to be vulgar," she said as she threw the sheet off, revealing her panty-clad body to her brother's hungry eyes. She loved the way he looked at her. She loved the way he lusted for her. She knew now that she was going to spend the afternoon being pleasured and pleasing her twin brother. She could think of nothing else.
"Vulgar? You mean telling you I'm going to eat your horny little cunt and then fuck the hell out of you is vulgar?" he laughed.
His words filled her with pure lust. She stepped near him and took his face in her hands, kissing his lips. She reached and felt of his almost fully-hard cock through his briefs. "Is this thing clean?" she teased.
"I took a shower," he whispered as he kissed her again, tenderly. "Do you want to wash it again?"
She grinned. "No, I'm not ever touching that thing again. Eww!" She ran to the bathroom and locked the door.
She realized that she was trembling with anticipation. Was it too late to back out? She could just tell him that it just bothered her too much. He would understand. He wouldn't force her if she could just make him see how it made her violate her conscience.
She removed her panties and got in the shower. As she washed, she realized that she was so turned on that her juices were flowing down her thighs and her nipples were as hard as rocks. She needed to get control of her thoughts and her body. This wasn't right. It was incest. But then, she had been having sex with Bobby and that was the same thing. She didn't think of that as incest though, she told herself. That was love. She was in love with Bobby. Having sex with him was an expression of their love for each other, not animalistic lust. Love was okay; lust wasn't. As she completed her shower and began to towel off, she had made up her mind. She was going to talk to Billy and make him see reason.
Realizing that she hadn't thought to bring any clothes into the bathroom besides the panties that she had worn, she wrapped her towel around her and walked to her room. Billy was propped up on her bed, still dressed in his boxer briefs, looking at her Ipad.
"You looking at porn on my Ipad?" she teased as she sat down on the bed next to him.
"Actually, no. Do you want to watch some? We can," he offered. "I was reading up on the baseball trades."
"No, I don't want to watch porn," she said. "Billy, I was serious. We have to stop this. You know I like it, but it's wrong. I just now thought about it in the shower and..."
Billy placed her Ipad on the bedside table and stood. He shucked his boxer briefs down, revealing his semi-hard, very thick cock. "You turning this down?" he laughed, as he began to stroke it, causing it to lengthen and harden immediately.
Amber eyed his cock. Her body needed that. Her pussy was buzzing, aching for him to fuck her. She didn't care if it was loving or if it was aggressive. She wanted it and needed it.
"This is incest," she muttered, continuing to stare at his ever-lengthening manhood.
He grinned. "Yes, it's incest, little sister. You love it, don't you?"
She looked in his eyes, pleadingly. "Billy?" she moaned.
"I know you've fucked other guys. Was that as exciting as incest?"
She didn't answer.
"Does incest turn you on, Baby Sister?" he whispered. "Don't you love it when your big brother gives you what you need?" He continued to stroke his now fully-engorged cock. She could see pre-cum lubricating the swollen, purple head. His cock was so thick and veiny. She thought it was the most beautiful thing she had ever seen.
