Julie heard the shower stop, then the closing of the bathroom door. It could only be Kenney, since the master bedroom had a bath of its own. She looked toward her door, knowing her brother would have to pass.
Kenney walked by, a towel wrapped around his waist. As he passed his sister's bedroom, he glanced in, saw her, and shoved his middle finger into the air at her. "Up yours!" he said, grinning. Then he ran to his room.
Julie smiled. Getting to her feet, she gathered up the jewelry and replaced it in the small chest where she stored it. Going to her door, she reached it just as the light went out. But her brother's door was open, and the light was on there.
Stepping into the hallway, she walked silently to Kenney's door, looking inside.
"Up who's?" she asked.
Kenney jumped, jerking the sheet up over his body quickly. Julie grinned when she saw the sheet standing up like a tent at his middle. He looked warily back at her.
"Don't you start anything, Julie," he warned.
"Looks like you've started something already," she laughed softly. "What are you hiding under that sheet? A little stick?"
"Don't come in here!" he squeaked, seeing her step into his bedroom.
"Why not?" she asked lightly. "I've been here before."
"Because… because I don't have my pajamas on yet," he said.
"You don't?" she lifted a teasing eyebrow. "Why, shame on you. I bet you were playing with yourself, weren't you?"
"I was not!" he yelped, holding the sheet tight at his neck.
Julie moved to the side of his bed, looking meaningfully down at the upstanding sheet. "If you weren't playing with that thing, why is it sticking up that way?"
"Julie," he warned, holding the sheet tightly, "if you don't get out of here, I'll… I'll call Mom!"
"So call," she said. Then before he could react, Julie grabbed the sheet and jerked it away.
Kenney's hands went immediately to his crotch, but he wasn't fast enough. Julie saw his hard cock and her hands moved like a striking snake. She grabbed his prick in her hand and pulled. Kenney yelped.
"That hurt!"
Julie relaxed her grip, but refused to remove her hand. She leaned over and looked closely at his cock and balls. "Hmmmm," she said softly. "That's quite a respectable hard-on, little brother. How often does that happen?"
"Julie, you better-"
"Why don't you shut up, Kenney?" she hissed at him, her hand moving now on his cock, sliding up and down slowly.
Kenney gasped as his sister's hand stroked his cock, her other one moving about his balls. "Yes, I'd say you have a respectable cock here."
He grunted, feeling sensations he had never felt before. Unlike his friend Mark, Kenney had never screwed a girl. No one had ever so much as touched his cock except himself. From the day he discovered he could come, he had been pulling off daily, sometimes two or three times.
"Still want to call mother, Kenney?"
He didn't answer. He couldn't answer; her hand pumping on his cock felt too good. He wiggled his naked ass on the mattress, and Julie gave a throaty laugh. "No, I don't think you do."
She played with his cock and balls for a few minutes, watching the foreskin slide back and forth, revealing the gleaming, swollen head of her brother's prick.
"You've never been circumcised, have you?" she said, her voice thick now. "I've never had an uncircumcised cock in me before."
"You do… you've been… " his voice trailed off.
"Been laid? Hell, yes! Plenty of times."
"Golly!" His eyes opened wide. "You better not let Mom find out-she'll blister your ass good."
"I doubt it," Julie laughed, sitting on the side of his bed and sweeping her fist up and down her brother's prick. "I don't think she would care, really."
"How do you know?"
"Oh, I've just got a funny feeling, you might say."
Kenney squirmed beneath his sister's hand, his eyes straining at her jutting breasts underneath the shorty nightgown, then at her exposed thighs. She had lifted one leg, crooked her knee, and he could see right into the crotch of her panties.
"Julie… you better stop," he groaned.
"Why? Don't you like it?"
"I mean, if you don't stop, well, something's going to happen."
"I know," she smiled at him. "You'll come, right?"
"Yes!"
"We can't let that happen, can we?" she said, pulling her hand away. As soon ass his cock was free, he started to pull the sheet back over his naked body. "Oh, no you don't!" she said, slapping at his hands.
Seeing that he wouldn't cover himself now, she stood up. "Want to have some fun, brother dear?"
"Fun?"
For an answer, Julie lifted her gown from her head and threw it to the foot of his bed. She arched her back, making her breasts arch out and up, the nipples long and hard. Hooking her thumbs into the waistband of her panties, she stripped them off quickly. Kenney stared-pop-eyed at his naked sister.
Julie spread her feet on the floor and shoved her hips forward, both hands pulling at the hair-lined lips of her cunt. "This kind of fun, Kenney."
He swallowed hard, unable to take his eyes from her pussy. The first one he had ever seen in his life. Kenney thought it was the best thing since Gunsmoke.
"Can't you speak?" she asked softly, twisting her hips as she rubbed at her clitoris. "You said up mine, didn't you? Well, here it is. Don't tell me you've changed your mind."
"Golly!"
"That's right-golly."
Julie climbed onto the bed with him, kneeling and still stroking her inflamed clitoris. "Has that thing ever been inside a girl, Kenney?"
He shook his head.
"Then it's about time it was, don't you think?"
He nodded his head.
Julie threw one slim leg over his shaking body, standing upright above him. He gazed up with his pop-eyed expression, staring in between her creamy thighs and directly at her pussy. He began to pant as his sister began to lower herself down. She squatted above his cock, her cunt inches away.
Reaching down, Julie took his prick in her right hand, stroking it as she rubbed her clitoris. She peered between their bodies, then at his face. "It looks like I'm becoming the fucking teacher of thirteen-year-old boys," she said. "You're the second one that age I've screwed."
Kenney was far too excited to pay any attention to her words. Julie had lowered her cunt down and was now brushing the flaring head of his cock along the warm, moist slit of her cunt, holding the hairy lips apart with her fingers.
"Feel good, Kenney?" she asked in a thick voice. "Doesn't that feel good against your prick?"
He gulped and nodded his head.
"Watch my pussy suck it up"
Julie squirmed, screwing her crotch downward. Kenney stared in amazement as the head of his prick spread the lips of his sister's twat. There seemed to be a great deal of heat there, and he was struggling to hold back his threatening ejaculation.
Holding the head of his cock by the lips of her snatch, Julie rolled her hips in a tight circle, using the muscles of her stomach and thighs, still using her fingers there. Slowly, very slowly, she inched down, taking more and more of his prick into her cunt. After approximately each inch, she would pause and circle her hips about, watching the expression on his young face.
"Nice, huh?" she whispered.
"Yeah!" he croaked.
"You just keep on watching," she whispered, "and see my pussy suck all your prick in."
Down she went, and finally her cunt hairs pressed into the wiry hairs at the base of his dick. She settled there tightly for a long moment, thrilled by the stretch and fullness of her pussy. That it was Kenney's cock, her brother's prick, inside her twat, made it all the more exciting.
Now, pressing her pussy against his pelvis, she hunched back and forth, then swung in tight circles. Finally, she began to lift her ass, sliding up on his cock slowly, and repeated her maneuver with just the head held in her snatch. She had intended to fuck him slowly, but the lust had gripped her tighter than ever before.
