"Ohhh, Tommy, I never thought a guy's prick could be so big… I've seen you naked before… when you've gone swimming and once when you came out of the shower at home, but holding it now… God, I never felt so excited before!"
He ran his fingers over her puffy vulva, combing through her dirty blonde pubes, feeling her seeping wetness.
"I never thought anyone's cock could be so big…"
"Go down on me," he gasped. "Suck it, Kathy, let me cum in your mouth. Taste my gism!"
"Yes… yes!"
He sat with his back against the headboard, Edna's pillow wedged against the small of his back. Kathy hunched over him, her long hair spilling like a net over his loins and thighs. She gripped his cock root and ran her tongue over his shiny, dome shaped cock head.
I never thought I'd be this excited about holding a guy's cock, let alone sucking it! she thought.
She drilled the tip of her fleshy wet tongue into his open piss eye, getting a taste of the thick cream she was yet to swallow. He moaned, placing his palm flat on the crown of her head.
"Take it all into your mouth, baby," he groaned.
She cupped his balls, squeezing them and feeling his inner sacs. Then she took his cock head into her mouth, running her tongue around the wedge-like bottom. She tugged at the flap of skin just under his cleft. She slowly went down on him, his thickness filling her mouth.
Her cheeks puffed out as several more inches disappeared between her voracious lips.
"That's it, baby, you're doing beautifully!"
She started to gag after three quarters of his staff was in her mouth. She came up again, sucking only on what she had successfully put into her mouth. Saliva bubbled out of the corners of her mouth and streamed down his shaft, dripping onto the sheets from his balls.
"More!" he gasped, gritting his teeth. "Ohhh, Jesus, that feels so good, Kathy. Take all of my prick into your mouth. I've been dreaming of this moment for so long! Do it, baby, do it to me!"
I'm trying, she thought. I'm trying!
She gradually became accustomed to his huge presence in her mouth and, by breathing solely through her nostrils and concentrating hard, she was able to take another couple of inches into her mouth. She could feel his dick head pressing back against the roof of her mouth, threatening to choke her, but she was determined to please her brother.
She gagged several more times. Seeing how hard she was trying to suck all of his dick, he sat back patiently and waited, reveling in the sensations that were already beginning to intensify.
"That's it, sweetheart… you're doing just fine…" he encouraged her.
Finally, after what seemed a long time, she was able to take all ten inches of his dick, until her lips were brushing right against his pubic hairs. Proud of herself, she started to suck faster, really getting into it. She could feel her cunt creaming. It throbbed continuously.
As if reading her thoughts, he reached over and inserted his middle finger up her pussy and massaged her clit button. She moaned, her head bobbing up and down, his cock glistening with her warm saliva.
She felt his cock head swelling up and his cock seemed to grow an extra half inch. But she was used to his size now and could go down on him without struggling with the urge to gag or throw up.
He started to hump up into her mouth, his head pressing back against the headboard, a wide grin of satisfaction on his slightly flushed face. She moved around so he didn't have to reach so far to play with her clit button. Her hips started to rotate and she could feel an orgasm taking firm shape deep inside her.
Her tongue whirled around his cock shaft, slapping it, caressing it, constantly moving. Her lips were tight suction cups as they tugged on his member. She massaged his big balls, feeling them tighten. She realized he was shortly going to cum.
"Kathy, I can't tell you how good that feels… Christ!"
She sucked harder, and he reciprocated by thrusting his finger deep into her cunt, faster and faster, making her gasp between sucks.
He gritted his teeth and humped harder into her mouth, making her teeth chatter. He could feel the fire rising up his cock shaft, like mercury in a thermometer. It wouldn't be long now… any moment and he would be filling his sister's mouth with his thick, creamy essence.
"Ohhh, Jesus," he gasped, both hands on his sister's head, forcing her to take all of his dick into her mouth each time she went down on him. "It's happening," he cried out. "I can feel it! Any second now and you're going to have a mouthful of jism, baby!"
I'm ready, she thought, her mouth watering so much that saliva was running freely down his gorged member.
"Ohhh, it's so good… so good!" His voice turned into a shriek.
He writhed on the bed, hands going up into the air. His toes twitched and his ass cheeks hollowed out.
"Ohhh!" he cried, and he exploded in her mouth.
Tears came to his eyes as his jism spurted into her mouth. The pleasure was indescribably keen. His ass rose off the bed as she sucked the juice from his cock, and it felt as if his entire body was being pulled upward toward the ceiling.
"Kathy! Kathy! Kathy!" he squealed, twisting and gyrating in ecstasy.
Kathy had to press down on his thighs to keep him from humping too hard into her mouth. At the rate he was moving her jaw would be broken and all her teeth knocked out!
She never thought so much cum could emerge from a teen's cock all at once. She swallowed, much of his jism escaping down the corners of her mouth, but not because she didn't like the taste. She had never tasted anything so delicious.
He continued to splash jism against the roof of her mouth like a fountain, thick juicy globs that. Kathy rolled on the end of her tongue before swallowing. She milked every drop of cum from his dick as it continued to jerk spasmodically in her mouth.
Tommy could swear his body was actually melting, like candle wax being held to a flame. The pleasure was unbelievably intense, and the realization that his beautiful older sister was the one giving it to him – that her lips were the ones moving over his dick with such precision – made his pleasure all the more rewarding.
His ass bobbed up and down on the mattress, sounding off the bedsprings like an alarm. He howled with pleasure, his entire body pulsating with it.
It's never going to end! he thought gleefully. She's sucking all the liquid from my body. In a few more minutes I'll be all shriveled up like a prune!
Kathy gave his cock root a squeeze and the last thick drop of jism left his tool and she swallowed it gleefully. He sighed deeply and fell back against the bedboard.
Reluctantly, she let his cock fall from her sperm stained lips.
CHAPTER FIVE
"Oh, look, Tommy, it's still hard," Kathy said, pointing to his erect cock.
Tommy smiled. "Did you think we were through yet?"
Kathy giggled. "I guess I have a lot to learn about guys."
"How was it with Edna?" he asked. "Wonderful… it was her first time, with another woman I mean, and it was just wonderful!"
He licked her nipples, lifting her tit to his mouth. She cupped his well-hung balls in her hand, gently massaging them.
"I want to fuck you now," he whispered softly. "I thought you were never going to ask." He pressed her back against the bed and spread her legs.
"Is this going to hurt?" she asked, concern suddenly written on her face.
"It might a little, but I'll make it as little as possible. Your cunt is even tighter than Edna's."
"It's just that your cock is so big."
He smiled proudly and positioned himself between her splayed legs. She looked like a statue, a perfectly realized work of art, her skin pale as ivory, smooth yet warm. Her golden pubic hair blended perfectly with her skin. He knew that before long her body would be just as tan as his and Edna's, only the area around her tits and groin and ass would remain white. And probably not even those areas, considering Kathy's liking of nude sunbathing and swimming.
