"It would all have been so different if I'd only waited ten more minutes," Robin Witters often thought.
All she'd intended was to return a serving bowl her older brother, Steve, had left at the cookout on Saturday night. Robin had some errands to run, so she decided to stop in at his apartment along the way. But when she arrived, she heard strange sounds coming from within.
"Robin," she heard him say. "Oh, Robin ... Yesss ..."
Robin pushed the door open, and was shocked to see Steve, naked, pulling on his cock, eyes closed, writhing on his bed. He let out an inarticulate cry as his long and stiff cock suddenly erupted, sending hot jets of sperm into the air, where they spattered across his hard, muscular chest. Again, he pulled, and even more sperm erupted, almost hitting him in the face.
Robin dropped the bowl. Suddenly, Steve's eyes snapped open, and when he realized what had happened, he blushed as red as a radish. Without a word, he dashed into the bathroom.
Robin entered the tiny efficiency apartment, furnished with a bed, a couple of chairs, a table in the kitchen nook and not much else. Stunned, she sat on the edge of Steve's bed, waiting for him to come out. She caught her image in the mirror on the back of the apartment door.
"What is it he sees?" Robin wondered. All she saw was the fresh young face of a girl just turned eighteen, with freckles, straight red hair, dancing hazel eyes, thin lips, and small, round tits so firm Robin sometimes just skipped wearing a bra. She and Steve shared the same facial shape and cheekbones, as well as similar noses. There was no doubting they were brother and sister.
"I don't get it," she thought. "I just don't."
When he didn't come out of the bathroom, she rose and knocked gently on the door.
"Steve?" she asked. "Please don't be upset. I'm not mad."
The door opened slowly. Steve, now clad in a blue terrycloth bathrobe, came out and avoided her gaze. He sat on the edge of his bed, and Robin joined him.
"So now you know," he said. "I never meant for you to ever know that."
"I don't know what to say," Robin said.
"He's so embarrassed," she thought. "I wish I knew what to do."
"I know I shouldn't feel this way about you," he said. "But the truth is, I've been in love with you for at least two years. Not being able to do anything about it is agony."
"Me?" she thought. "I'm not beautiful."
"You are so beautiful," he said, as if reading her thoughts. "But you're my sister, and I love you, and I would never, ever, do anything to hurt you."
"Oh, Steve," she said, and embraced him, laying her head on his shoulder. She felt his lips caress the top of her head, and she began to relax.
Until she spotted the terrycloth moving.
Steve's hand traced up her side, stopping just under Robin's breast. Robin's eyes widened as Steve's cock thickened and rose, poking out of the terrycloth. She found the sight mesmerizing.
"How big does it get?" she wondered.
"Robin, I - "
She tried to pull away, and suddenly felt Steve's lips on hers as he pulled her tightly to him and rolled her onto the bed.
"Steve, don't!"
"I love you," he hissed, his eyes wild. "Please! You don't know what you do to me!"
Steve was on top of her now, kissing her face, shoving his hard cock against her jeans. The heat from his groin seemed to penetrate to hers, and, as she struggled, she also humped her pussy against his demanding dick.
All of a sudden, Steve stopped and let her go. He sat up and covered his face with his hands. Robin could see his shoulders trembling as he cried.
"I'm so sorry, Robin," he said. "I lost control. Having you so near, wanting you so badly. I'm so sorry you found out how I feel."
"It's okay," she said. "I'm glad I know. Why don't we forget this ever happened? We won't talk about it again. You'll meet a girl soon anyway and forget all about me."
"I should leave town," he said. "Maybe join the Army or something."
"We'd all miss you," she said. "Who else is going to fix my car? You know how Dad is with tools."
Robin felt relief when Steve smiled; the storm had passed.
"You've always known what to say," he said. He kissed her forehead in the brotherly way he always had.
"Not a word," said Robin as she rose to leave. "This never happened."
"Right. Thanks for being understanding."
***
But Robin couldn't forget it. She could not get the image of Steve's long, stiff cock out of her mind, wondering what might have happened if she'd touched it.
"Maybe I should have," she thought. "Get it out of his system."
Except that Robin didn't really know how to do anything like that. Her experiences with sex had been very limited, mostly some mutual groping with a couple of guys she knew in high school. She'd had a few dates which didn't work out, but everything Robin knew about sex basically came from the Internet.
When she finally dropped off to sleep, Steve's ardor came back to her in dreams, and in one of them, she kissed him back and didn't resist. She dreamed she removed his robe, and she dreamed they kissed as lovers. When she woke, her sheets were wet and reeked of musk.
"What's happening to me?" she wondered. "What did he do to me?"
Robin went to a local beach with some of her friends a few days later, and came home wearing a T-shirt over her bright green bikini.
"Anyone home?" she cried.
"Me," came Steve's voice. "I'm doing laundry."
"Okay."
Robin took a look in the refrigerator, took out two beers, and went down into the basement, where she saw her brother pour some detergent into the washing machine and begin the soak cycle. She sat down on the old ratty sofa where she often came for peace and quiet. Steve sat next to her, and they sipped beer quietly for a few moments.
"I know we said we'd never talk about it," he said, "but I really can't get what happened the other day out of my mind."
"Oh, Steve ..."
When he wrapped an arm around her shoulder and pulled her close to him, she did the same.
"Robin, I think I'm more in love with you than ever."
"Don't say that, Steve. Just don't."
He kissed her, gently this time.
"Don't you like that?" he asked, looking deeply into her eyes. "It feels good, doesn't it?"
Robin felt heat in her pussy when he kissed her again, and when he pushed his tongue into her mouth, she only resisted a little.
"Steve, this is incest! We could go to jail for this!"
"Call it what you want. I'm calling this love."
When he kissed her again, Robin felt his hands slide under her T-shirt, and she gasped when his hand closed over her breast.
"Steve, you shouldn't - "
His other hand pulled the string holding the bikini top in place, and Robin felt it fall away. Steve's hand closed over Robin's rapidly stiffening nipple, and she felt her resistance melting even further.
"Mom could come home any minute."
"She's at the grocery store. We have at least an hour."
Steve tried to remove the T-shirt, but Robin somehow managed to keep it on. Both Steve's hands were massaging her breasts, and he nuzzled them through the cloth.
