Michael Smith - Siblings

"Oh – ah – I love your cock up in me – it's so big I feel like I'm popping! Oh – it's good, it's good – oh, shit – keep – fucking me -don't – stop!"

Sweat was running off my forehead and my hair, the soap was getting in my eyes, and I didn't care. I could feel the pressure building and there was no way now I could stop, even if either of us wanted to. I squeezed my sister's hips to signal her that my climax was on its way.

"Yes – me, too – I'm there! – oh, shit – that's – so good!"

I increased speed, gasping as loudly as she did. And then I came, in great, shuddering, shocking contractions. I tried unconsciously to push into her even farther as I ejected millions of sperm into her lower intestine. I almost laughed at that unbidden thought, but I was lightheaded and gasping for breath. Now her sphincter was rapidly dilating and tightening, and that helped the ejaculations to go on and on, longer than ever before. From the hoarse, throaty sounds Alex was making I knew she was climaxing with me. God, was there ever a feeling like this?

Alex's grip on the wall rod was loosening. She was so out of it from her own multiple climaxes, I was afraid she might smash her face on the tile wall. I got my arms around her hips as she began to slide downward, and I slid with her, both of us panting loudly. Her ass was pressed against my groin and she was still impaled on my cock. We somehow landed on the bottom of the shower stall without hurting ourselves. She was face-down with her cheek cushioned on her wrist, gulping the hot, steamy air. I was lying on top of her, also struggling to get my heart rate down, supporting most of my weight on my shaking arms. If my elbows unlocked, we'd both crash. My cock was still buried to its root in her rectum. The passage was still so snug it had no room to contract. And I was content to leave it there awhile longer.

What finally brought us around, rousing us out of our half-swoon, was the water. It was getting colder and the steam was disappearing. I had no idea how long we had fucked or how long we had lain on the floor, but it was long enough to use up all the hot water. I had sunk down on my elbows – my arms could never have lasted that long – and slowly withdrew from Alex's fantastic asshole.

"Ohhhhh…" She moaned softly, perhaps feeling the loss. I leaned over and kissed her lingeringly at the base of her spine. So beautiful, my sister, so filled with me for however long it had been. It's your decision, but I think we'll do it again.

I sat back on my heels so the now icy water splashed off her back. My reaction to the change had been gradual; her's was electric. She gasped at the shock, her green eyes snapped open, and she struggled to get to her knees and then to her feet. I stood up, still a bit shaky myself, and helped her. It took a minute, but then she deliberately stepped back under the water and rinsed the sweat out of her hair. She turned slowly in position, combing her fingers through the dark red strands, while I stood and watched. God, I loved her.

She saw my expression and her peculiar sense of humor got the better of her. She smiled and stepped back to me, hooking one arm around my neck. With her other hand, she took my hand and slipped it, palm up, between her slightly parted thighs. She can't possibly want to screw again, I thought.

She brought my mouth down to hers and kissed me. I stroked my hand back between her legs, delighting still in the smooth, wet flesh and the curly hair brushing my wrist. And then she tapped the tip of her little red tongue against my front teeth, pressed her thighs closer together, and pissed in my hand!

That's how well we understood each other – that she could do something that crude at such an emotional moment and know that I would be amused. The cold shower splashed off my shoulders while my cupped hand filled with her warm urine, and I cackled at the joke. Here, now, under these circumstances, it was funny!

I extricated my hand, trying to hold on to some of the pale yellow liquid, while she grinned mischievously. I squeezed her cheeks – not roughly – to force her mouth open while she squealed and tried to bat my hand away.

"I ought to dribble this down your throat, you know. But I'm a nice guy so I won't." Instead, I trickled it across her breasts. "You can have it back," I added. "You might run out!"

I had to stay late at school one day in September of that year, working on a project for journalism, so I was in a hurry to get home. I didn't stop at the restroom before I left, and by the time I reached the house, I had to take a piss so badly I was walking knock-kneed. I got halfway down the downstairs hall and saw that the bathroom door was closed – Mother must be in there – made a U-turn and hurried upstairs. I dropped my books in the hall and charged into the upstairs bathroom, already struggling with my zipper.

Alex looked up startled from the toilet seat, her jeans around her ankles and her shirt rucked up around her waist. I moaned. "What's your problem?" she wanted to know.

"I can't wait!" I was fishing out my cock. "I'll have to use the shower stall!"

"Hey, wait! There's room here…" She spread her legs wider and slid back a little on the toilet seat. "Just aim between my legs, for chrissake."

I didn't hesitate. I stepped in front of her, trying not to get my feet tangled in her pants, pointed my cock at the front slope of the bowl, and let go. In my effort to control the high-pressure yellow stream, I aimed too far forward and managed to splash both myself and my sister's legs.

She threw up her hands in surprise. "Watch it, Michael! Here, gimme that…" She reached forward, took my cock in hand like she was milking a cow, and pulled me forward. I had to let go of it and quickly support myself on her shoulders to keep from falling on her. She used both hands to pull me to within a few inches of her pussy and grinned up at me. My cock was engorged with internal pressure and completely filled both her hands. "You can lead a horse to water," she laughed.

The golden stream just went on and on. She watched speculatively and then aimed closer to her crotch. The spray was now wetting the outer part of her bush.

"What are you doing, Alex? Do you*want* me to piss on you?"

"I dunno, I've never tried it. Might be fun as an experiment, though…" Alex would try almost anything at least once, and, these days, the more unusual the better. She hadn't bitten off some guy's penis or fucked a Great Dane (as far as I knew), but otherwise I suspected her taboo list was pretty short. I finally finished draining the tank and took my cock back so I could make sure it got the customary final shake, and tucked in back in my slacks. Alex looked pleased at the strange look I gave her as I left the bathroom.

What I didn't know was that one of Alex's girl friends had a brother in college who belonged to a fraternity that claimed to own the largest lending library of pornographic books and magazines in the state.

The brother was presently interested in fringe erotica, having apparently become bored with standard fuck-and-suck scenes, and Alex and her friend had been spending some time in his absence evaluating photos of bestiality, bondage, spanking, enemas, ass-fucking, and erotic urination – "golden showers." Why my sister was turned on by this particular sexual variation I had no idea. Her interest soon waned – rather, it found new outlets, some of them equally bizarre – but it sure led us to some interesting experiences.

I should probably add that I had no theoretical objection to any of this. I was as fascinated by some types of sexual experimentation as Alex was. I drew the line at anything involving shit, however. Happily, she agreed with me. But some of our water games during that few weeks had very erotic overtones.
