Chapter 4

MacIntyre could feel the tip of his cock slowly entering his big sister's talented throat.

Sally could tell right away that it was going to take all of her sexual skills to give her brother her throat completely.

She relaxed the muscles in her throat as much as she could and concentrated on breathing exclusively through her nose.

She inched upward toward the base of his cock, caressing the shaft with her moving lips.

MacIntyre figured that she had better hurry up and get him all the way in or he was going to shoot before complete penetration had been achieved.

He tried to think of other things so that his orgasm would not happen so quickly, but still his semen swam around inside his scrotum impatiently.

He could feel the little tickle in the base of his cock that told him his climax was inevitable.

MacIntyre could not believe how intense the pressure in his balls and his cock had become by that time.

He was certainly hornier than he had ever been before.

He knew that this orgasm was going to be the most intense of his life.

He could feel his balls burning with a yearning for orgasm.

And still Sally's lips approached the base of his cock.

She could feel his cock throbbing inside her hot throat.

She found that she could do it without any pain.

Once she made that realization she thrust forward hard with her head.

Then her lips were wrapped around the base of his cock and her nose was buried in the thick patch of pubic hair that grew above his shaft.

She squeezed his balls more sharply and began to move her head back and forth very fast.

It made it seem to MacIntyre more like he was fucking her mouth than getting a blow job.

Sally drew back with her lips slowly until once again only the head of MacIntyre's cock was between her parted lips.

Then she plunged forward with her head so that the whole ten inches of thick cock meat rammed into her throat at the same time.

She only did this three times before she could tell that her baby brother was on the verge of blowing his load.

All of his muscles were so tight that he was trembling and there was a vein in his temple that was visibly throbbing.

Getting sucked off by Sally Symms would not be recommended to anyone with even the slightest heart condition.

Then MacIntyre's back teeth came unclenched. His mouth fell gaping open.

He moved his hands to Sally's soft shoulders and squeezed her so hard that all of his knuckles turned white.

Sally could tell that she was about to be served with a hot meal.

She drew back with her head so that her lips were wrapped around the base of his throbbing purple glans.

She wanted to taste his come as it landed on her tongue.

She wanted to roll his come around on her tongue and savor the flavor.

She wanted to feel his hot cream slithering down her throat.

MacIntyre let out a scream that reminded MacIntyre of a werewolf howling at the full moon on a partly cloudy evening.

He was amazed for a moment that such a sound could come out of his body.

It wasn't a human sound. It was sound that an animal would make.

But the thought passed quickly as he was caught up in the throes of his ecstasy.

He felt the fiery come shoot up the stalk of his cock into his sister's waiting mouth.

He felt like she was going to suck his balls dry with that talented mouth.

The first shot of come was so huge that it filled Sally's mouth completely.

She had to puff out her cheeks to keep it all in her mouth.

Some of the stuff dribbled out of the corner of her mouth and landed in the tub between her knees.

But she managed to swallow most of it down, feeling the hot come soothe the burning she felt in her throat from the brutal penetration she had put it through.

Spurt after spurt of fuck juice spat from MacIntyre's hole into Sally's mouth.

She quickly realized that she loved the way MacIntyre's come tasted a lot.

It was sweeter than any come she had ever tasted, and she considered herself quite an expert on the subject.

Time was slowed by the intensity of the pleasure MacIntyre was feeling.

He thought that his orgasm was going to go on forever.

In reality the whole thing only lasted about ten seconds.

That is a long time to be all caught up in previously unknown bliss.

When the orgasm was over MacIntyre felt all of his muscles relax at the same rime.

Sally took her mouth off of his cock and licked it lightly a couple of times before releasing it.

It was becoming flaccid and already the tip insisted on drooping downward.

MacIntyre's knees were still shaking as he listened to himself catching his breath.

Slowly but surely his heartbeat was returning to normal.

Sally could still taste some of his come on her tongue.

In spite of its sweetness, it still had the salty tang of the sea.

She wanted to suck her brother off frequently. She knew that with one orgasm under his belt he would be able to fuck her cunt for much longer.

She wanted him to stroke her inner pussy with that hard rod for hours and hours, and her clit quivered even as she thought about it.

Then she saw that MacIntyre's knees were shaking and she reached up to take him hand.

"You look a little shaky. Why don't you sit down here in the bottom of the tub with me," she said.

She moved so that she was sitting in the tub. She leaned back and stretched her legs out in front of her.

MacIntyre sat on the other end of the tub, but could not lean back because of the metal faucets.

He placed his feet along side Sally and sat between hers.

"Did that feel good?" she asked, tilting her head a little to one side.

The naughty expression on her face told MacIntyre that she already knew the answer.

"It felt better than anything I've ever felt before. I want to make you feel just as good, Sally. But-"

"But what?" Sally asked, giving his right hand a little squeeze.

"But I don't know how," he completed, looking right into her blue eyes.

"That's why I'm here. I'm going to teach you," Sally said.

"I can't wait for the first lesson," MacIntyre said.

"You get the first lesson right now. I want you to play with my tits."

"Your tits are beautiful. It sounds silly, Sally, but I feel it's almost an honor to touch your tits."

"And I feel the same way about your cock. Most of what you need to know about pleasing me will come naturally. You already have all the equipment you are going to need."

MacIntyre blushed and self-consciously looked down at his cock which was resting limp against the inside of his thigh.

Even when his cock was flaccid it was still quite a thing to behold.

It didn't lose much of its thickness, and it dangled a full eight inches.

Sally grabbed both of MacIntyre's wrists and placed his hands on her tits.

MacIntyre opened his fingers and found there was no way he could hold all of her breasts at the same time.

They were just too big, but he squeezed what he could hold.

He could feel her hard nipples pressing against the centers of her palms.

"That's it, Mac. Nice and gentle. Move them in little circles. Pull them apart and then push them together. Now squeeze. Oh God that feels good. I think you are going to catch on pretty quickly."

MacIntyre could feel his confidence growing as he squeezed and moved her breasts.

When he pressed her tits together her cleavage was long and deep.

Sally could feel her glands pumping out fresh cunt juice.

Her natural lubrication was spilling into the tub along with the water from the hot shower.

The whole bathroom was filled with steam at that point.

The two siblings were peering at each other through a hot fog.

"Now touch my nipples," Sally said. "Roll your fingers over my nipples very gently. Oh YES!"

MacIntyre sure could feel his face glow with pride when he realized he was giving this beautiful woman pleasure.

It no longer mattered that she was his sister.

Any guilt he had felt had completely left him.

He knew that anything that felt that good had to be perfectly normal.

Anything that was that much fun could not be evil and bad.

"Pinch and pull at them," Sally said. She closed-her eyes and placed her palms flat in the bottom of the tub.

She could feel the ache in her loins growing in leaps and bounds.

He pinched and pulled at her nipples just the way she liked it.

He did it hard enough so that it hurt her a little bit.

But Sally was the kind of girl that liked a little pain when she was especially aroused.

MacIntyre could feel her nipples growing firmer and larger under his grip.

Soon they were just as big as when he watched her from the closet.

"Can I suck them?" he asked, wincing almost visibly after hearing himself ask it.

"Yes, but not now. Let's get out of the shower and dry off. We can go to your room. I think you might like to lose your virginity on your own bed. Did you know that I can fart out of my pussy?"

MacIntyre could not help but laugh, but his eyes went wide as he watched.

She lifted her cunt up out of the water and he could see her cunt lips pucker.

She then lowered her hips back down into the water and MacIntyre watched her inner labia bluster outward, accompanied by many big gurgling bubbles.

"How do you do that?" MacIntyre asked, suspecting that his knowledge of the female anatomy was not all it should be.

"Muscle control," Sally said with a giggle, and then stood up.

MacIntyre turned and shut off the shower water with several turns of his wrist.

They stepped out of the shower and pushed the bathroom door open so much of the steam would leave.

Still wet they both got into their robes and moved out into the hall.

They grabbed big towels and made there way to MacIntyre's room where they dripped quite a bit carelessly.

Sally was so hot that she couldn't take the time to dry off before leaving the steamy bathroom.

She kissed MacIntyre on the tip of his nose and then flicked the tip of her tongue back and forth beneath his ear.

"After I teach you how to suck my nipples, I'm going to teach you how to eat my cunt she said, her eyes ablaze with passion.

MacIntyre gulped.

He couldn't believe his luck

He was one horny sixteen-year-old.

And his sister was twice as horny!

Boy oh boy!
