"I'll see what I can do." Adam said closing the door.
That Friday evening, Kate had a candlelit dinner ready for her and her fiance, Francis. During dinner, she half-listened to him droning on about the office, some new software he was using to calculation bond yields, the latest gossip about IPOs.
While he talked, her mind drifted off to the time she and Adam were snuggling under their grandmother's quilt, watching TV in the family room. Adam was a popular athlete in high school, so he was always bragging about "sparking girls" in various places - cars, under the bleachers, risky encounters in the library, some underwater fondling in the pool. All of his sexual activity made her curious - he was no longer her goofy, skinny brat brother, he was a long limbed athlete who had big hands and feet. Of course, she was curious.
Falling asleep, Adam had shifted under the quilt so that he could lie down on the couch. He moved his bare feet to sit on his sister's lap. Adam wore size 13 shoes. Kate absently squeezed his toes. Then she looked down at his feet and realized he was much bigger than her fiance, Francis.
Curious. Very curious. Need to know. All these thoughts ran through Kate's mind as she parted Adam's legs so that she could slide between them like a pair of scissors. "Great calves, been working out?" she asked. But Adam was asleep. She shifted herself between his thighs, peeled back the quilt to look at his boxer shorts. With her perfectly manicured fingers, she poked and prodded the edge of his boxers to get a peek. No luck. Then she saw the slit of the shorts' fly and ran 2 fingers to gently part the material. She reached in and pulled his soft dick out. Even soft, he was larger than Francis.
With one hand, she began to rub herself moist and warm. With her other hand, she held her brother's floppy organ, marveling at his thickness and girth. Omigod, this is so wrong, but I am so curious. She knelt forward and lightly licked the head of his dick. With her middle finger, she was twirling the nub of her clit. Omigod, I can't believe I'm doing this. She put his head in her mouth and sucked gently. My own kid brother. It made her madly finger her clit. Then, to her surprise, she felt his head swelling in her mouth, his shaft filling her hand. Shit, he's getting hard. He rose to an impressive size and she admired the sculpture of his masculinity. But how was she going to tuck him back into his underwear like this?
"Kate?"
She shook herself. Beneath the dinner table, she had her hand between her legs.
Francis was smiling, "I was telling you about Sommer's firm thinking they were going to cheat GAAP rules? I mean, really!"
The memory of her brother's erection protruding from his shorts was still very much on her mind when she led Francis to the bedroom. He complained he was too full after dinner to have sex, so she laid him down and sucked him off, thinking about her brother's lean body and his cock in her mouth instead.
