In spite of the circumstances, the soft touch of her fingers on his prick sent a warm, tingling glow through his cock.
The exciting feeling between her legs increased as Marci felt his prick-shaft begin to swell and throb in her hand. Staring in complete fascination, she watched his swelling purple cock-head start protruding from his foreskin. Gently squeezing his prick, she couldn't believe how big his cock was getting.
"No, Sis, this isn't right," he weakly whispered as her hand began moving up and down the length of his fully erect cock.
The young girl had never been so excited in her life, and she was finding it difficult to breathe as her fingers explored every bump and vein on his big blood-engorged prick. Slowly skimming the soft foreskin up and down over his throbbing cock-shaft, she rubbed his deliciously hot cock-head against her soft, warm cheeks, up through her hair, under her chin and lightly across her moistly parted lips as his body trembled and lurched with ecstasy.
"Oh, God, Sis!" he whispered, completely surrendering to her loving caresses when she momentarily released his tingling boner from her fingers. "Don't stop honey… don't stop!"
Grasping his prick more firmly in her trembling hand, she was shocked at the expression on her brother's face. His mouth was gaping open, with his lips drawn back from his teeth while his glazed eyes rolled up crazily toward the ceiling.
A feeling of triumph surged through her body when Marci realized how easy it was to control a man's emotions through the manipulation of his cock. She couldn't believe the intense power she had over his body as she rapidly learned how to please him. The faster she stroked his cock, the wilder he shivered and lurched, and when she slowed down the action, he moaned and begged for more. This was the first time in years that her big brother hadn't dominated her.
"Please don't stop, Sis!" he groaned when she again momentarily released his prick. "Oh, God, honey, don't stop! Please don't stop!"
Kirk thought he would lose his mind with ecstasy as she brought him close to a climax time after time, only to let him slip back and skillfully bring him up again.
"Oh, God, honey, that feels so good!" he moaned as her gentle fingers continued deliciously stroking the length of his throbbing cock-shaft.
As his body began lurching more violently, Marci began instinctively moving her hand more rapidly up and down over his big, straining prick. Crazed with the wild excitement, she could feel her hot cunt juices oozing out into her panties. She was pumping faster and faster while her brother lurched and moaned on the chair. Kirk could feel an explosive orgasm building up deep in his balls. He felt as if his blistering prick was burning as his jism started its fiery journey up through the tingling length of his cock.
"Oh, sis!" he shouted in ecstasy as the thick hot cum gushed out from his big prick-head, splattering against her startled face. Thrilled by what was happening, she continued pumping frenziedly on his spurting prick until the last bit of jizz dribbled out.
Finally releasing her brother's rapidly shrinking prick, she began wiping her cum-drenched face with the back of her hand.
When she drew her hand across her mouth, she was delightfully pleased with the slightly salty, bitter-sweet taste of his jizz, remembering that Joyce had told her how good cum tasted.
Kirk was completely exhausted, his eyes closed and head thrown against the back of the chair as he slowly recovered from his intense climax. With his burning lust now relieved, he suddenly felt terribly ashamed for allowing his little sister to jack him off. Unable to look her in the eye, he stood up and closed his zipper. Still not saying a word to her, he walked upstairs to his room.
When he'd gone, Marci just sat on the floor for several minutes, trying to sort her thoughts out. It had been a traumatic experience for the young girl, yet jacking her brother off had been the most exciting thing that had ever happened to her. Finally pulling her cut-offs down, she lustily finger-fucked herself to a wonderful orgasm before going to bed.
Unable to sleep, she lay tossing and turning for hours. She was finally almost ready to fall asleep when she heard her bedroom door open.
"Who's there?" she whispered.
"It's me," she heard her brother answer as he closed the door behind him and walked over to the side of her bed.
"What do you want?" asked Marci turning on the bedside lamp.
"Well," he nervously began, "I was wondering if you'd like to jack me off again?"
"Sure!" she squealed, throwing back the covers. "If you'll play with my pussy while I'm jacking you off."
Marci was completely naked, and Kirk just stared numbly at her firm young tits with the hard pink nipples standing up so deliciously erect. Her youthful body tapered down to her slim waist and then flared gently out again at her softly rounded hips. Her shapely little legs were slightly parted, exposing her smooth inner thighs that led up to her delicious little gold-fringed pussy.
"Take your stupid shorts off," she commanded as he stood there staring at her.
An exciting tingle rippled through her pussy when he dropped his shorts. Earlier in the evening she'd only seen his prick through his open fly, but now she was staring at a man's balls for the first time in her life. Her unbelieving eyes focused on his hairy sac that swung lewdly between his muscular legs. The sight of his long, hard cock-shaft thrusting up from his mass of curly pubic hair made the juices flow hotly from between her legs.
Crawling into bed, Kirk drew his little sister's soft, warm body up against him, covering her moistly parted lips with his mouth as they rubbed their hips against each other. He slowly moved his hand down over the smooth flesh of her back until he had her soft, wiggly asscheeks gripped in his palm, and, as he pulled her sweet, naked body closer to him, Marci could feel his throbbing cock burning against her quivering belly.
Finally releasing her cute ass, Kirk trailed his hand around her body until it was resting between her smooth inner thighs. Trembling with lust, he let his fingers slowly wander up until they brushed against the hot, juicy opening of her little virginal cunt.
"Ooooooooooh!" Marci excitedly whimpered when his finger gently moved up and down along the edges of her soft, wet pussy-lips. Dipping his finger into her creaming cunt, he slowly moved the tip of his digit up toward her erect little clitty.
"Oh, Kirk," she whimpered, covering his mouth with her warm, moist lips. "That feels so neat."
Kirk had fucked his share of the girls in town, and he expertly massaged his little sister's clit until she was squealing with joy. Deciding to give her even more pleasure, he began plunging his thick middle finger in and out of her little juice-drenched cunt, making certain to brush his finger against her clit with each inward thrust. The ecstasy was almost more than she could stand, and with every thrust of his plunging finger, he was carrying the squealing youngster to new heights of blissful joy.
"Oh, Kirk!" she cried, wildly rotating her slippery cunt around his thrusting finger. "Go faster, honey! Don't stop! I'm almost there!"
His wildly aroused little sister let out another squeal of joy when her body suddenly exploded into a bone-rattling orgasm, the first climax she'd ever had without using her own hands. She kept coming for what seemed hours to her, and when she finally stopped, she gave him a deep, tongue-sucking kiss.
Finally opening her eyes, she was once more aware of the big, hard boner that was throbbing up from between his legs.
"Kirk," she whispered as she began sliding his velvety foreskin up and down over his throbbing cock-shaft. "Would you like me to suck you off?"
"What do you know about blow-jobs?" he asked in a shocked voice.
"Joyce told me."
