School was out for the summer. Amber had graduated, 9th in her class. She had gotten enough scholarship money that, if she continued to live at home, she would have enough to pay for her tuition, books, and other fees at the local community college where Bobby and Billy were already enrolled.
In the two months since she and Bobby had first become intimate, Billy had become serious with his girlfriend and often stayed all night with her at her apartment. This afforded Bobby and Amber some privacy. They still had to be careful if their mother was home, but she rarely came upstairs at night.
While Bobby and Amber found opportunity, almost every day, to enjoy a kiss and, perhaps, a little fondling, they didn't engage in intimate activity very often. Amber had told Bobby that she never wanted to do anything really intimate when their mother was home and that she didn't think it was good for them to do those things often. She made it clear that she wanted Bobby to continue with his normal dating life and that she would too - should such opportunities present themselves.
Her "growth spurt" had continued. She had gotten even taller - she was now 5-3, and she had gained 10 more pounds. Best of all, her breasts had gotten even bigger. She was practically giddy when she went shopping one day and bought a couple of new, B-cup, bras. She couldn't wait to model them for Bobby. She had cleavage, now. Her body had become shapelier, as her waist stayed small while her bottom filled out even more. Now she was beginning to worry that it might get fat! She bought clothing that accentuated her shape and even gave a slight hint of her newfound cleavage. She didn't want to look slutty, but she did want to look like a woman. She kept her hair cut moderately short and, at Bobby's suggestion, often wore her hair in pigtails.
She was getting plenty of male attention now and really didn't know how to handle it. She hadn't started college yet, but a couple of guys with whom she had attended high school had called her, asking for dates. She had turned them down, remembering how they had treated her before she got her growth spurt. They were obviously shallow. She didn't like shallow.
One boy, Sam, who went to church where she attended, however, did hold some attraction to her. He had talked to her a few times at church and had always seemed friendly to her. Shortly after she graduated he asked her if she would like to attend a party for the college-aged people from church. She readily accepted. It had turned out to be pleasant, and not a big deal. He hadn't done anything even slightly inappropriate and, when he walked her to the door that evening, she had kissed him on the lips, very briefly.
She hadn't expected, however, that Bobby would ask so many questions about her date. He wanted to know every detail. He seemed a little miffed when she told him that she had kissed Sam at the end of the date.
"Bobby, I've never asked you to explain anything about a date, have I?" she asked him. "Am I your girlfriend?" she asked, angrily.
Bobby looked hurt. "No. But you know how I feel about you. I'm sorry. This is just hard on me. I wish I hadn't said anything," he explained.
Amber took her brother's face in her hands and leaned forward so that their foreheads were touching. "Bobby, what we have is...special and it's unique, but it's forbidden. We have to act as if there is no future in it..." she looked into his eyes, as she brought her face back a few inches. "We don't know yet if there is a future for 'us', right?"
Bobby thought back on the night that they first became intimate with each other. He had masturbated while she watched, then he had sucked her breasts and did oral sex on her. Later, he had showed her how to assist him as he masturbated and he had, again, worshipped her little, sexy body with his mouth and hands. They had slept together, naked, all night. They had talked about their love for each other.
He had assumed that night that they would soon be having intercourse, but it hadn't happened. She had never mentioned wanting that and he was not going to bring it up. He wanted it to happen, but if it never did, it was okay. He knew that he was in love with Amber, but he realized that having intercourse with his sister could lead to major life problems. Still, he was jealous when she gave her attention to other guys. Her body had continued to develop and she was now a fully-blossomed, beautiful, young woman. He knew he was no longer the only person who noticed this.
"Earth to Bobby," Amber smiled. "What's going on in there, Big Brother?"
Bobby took her hand. "I was just thinking about our situation. I'm just crazy about you. Right or wrong, forbidden or not, I love you. I know what you just said is right, though. We have to act as if we have no future together. I agree. I will try to do better, but you'll forgive me when I'm jealous, right?" he grinned.
"Yes. It's flattering. I just don't want you mad. Okay? You're my man, you know that? I'm your woman, too. I am. I want to be!" she whispered.
They kissed, passionately.
*****
Both Bobby and Billy were taking summer classes, but at different times. Amber occasionally helped one or the other of her brothers if they needed help getting a lawn mowed while the other twin was at class.
One day she had helped Billy mow a lawn because rain was threatening that evening. Billy was always glad for Amber to help him, and was glad to pay her half of whatever he made, even though she rode the riding mower and he did the really hard work. He knew that they needed her help from time to time and he wasn't going to do anything to cause her to stop helping them.
They had gotten home, Billy had showered, and Amber had just finished her own shower. She heard Billy shouting before she ever came out of the bathroom. She could tell he was angry and that he was using quite a bit of profanity, including the word, 'bitch', several times. By the time she had dried off and gotten dressed, she had figured out that he was on the phone.
When she came out of the bathroom, she glanced in her brothers' open bedroom door and saw Billy throw his cellphone down on the bed and yell, "fucking bitch!" He was dressed only in athletic shorts and, of course, looked almost identical to Bobby. Since she and Bobby had become intimate, a surge of forbidden lust surged through her body when she saw either brother with their shirt off. They both were handsome and well-built. Her sexuality had been awakened and, she admitted to herself, somewhat shamefully, that the thought of incestuous relations was one of her strongest turn-ons. "What?" he shouted at Amber when she stopped and looked at him curiously.
"Nothing. You seem upset. Can I help?" she said calmly, trying to focus on his face instead of allowing her eyes to wander down his muscular chest and flat stomach.
Billy lay back on his bed and pulled a pillow over his face and yelled into the pillow. Amber tentatively walked into his room.
Billy lay the pillow aside. "That was Teresa. She's breaking up with me," he said, obviously on the verge of tears.
Amber sat on the edge of his bed and took his hand. "I'm so sorry, Billy. Why? Did she give you a reason?"
"She wants to date other people," he muttered. Billy was not an emotional person, but Amber could tell that he was on the verge of tears.
"That breaks my heart, Billy," she whispered.
Billy's eyes flashed with anger, but a quick glance in his sister's face told him that she wasn't being sarcastic. Who was this girl? How could she still treat him tenderly and commiserate with him when he was hurting? A tear coursed down his cheek; he angrily wiped it away. "Thank you, Amber."
"Billy?"
"Yeah, Sis?"
"Please don't get mad at me, but I don't think calling her a bitch is going to help the situation. It will just ostracize her - and it doesn't help you either. A soft answer turns away wrath," she said tenderly as she stroked his hand, thinking how much she would love to kiss his handsome face.
