Michael Smith - Siblings

So I really went to it, slamming into her like a piston in a steam engine. Her head was jogged forward by two inches on each stroke, but if she felt any strain it was lost in her sexual delirium. I hadn't even touched her nipples, yet they stood up stiffly and seemed to pulsate.

My climax started as a tingling in the soles of my feet. I wanted very much for us to share our first "official" orgasm, and the thin, wailing moan coming from my sister's writhing mouth made me pretty sure we could do it.

She suddenly wrapped her legs around my waist again and clung frantically to my arms and shoulders, as if she were about to fall off a cliff. Her shuttering, gasping climax might indeed have thrown her off the bed, except that she triggered my own orgasm. My paroxysms continued for half a minute and she jerked and trembled again with each new spasm.

As our hot-wired bodies slowly coasted to a halt, I rolled carefully off Alex, who turned on her side to face me. Both of us ran with rivulets of sweat. We kept touching each other's faces and bodies, gently, hesitantly, awed by the intensity of what we had just experienced. Both of us were bright red in the face and struggling to get our wind back.

I was finally able to speak. "I was afraid I might hurt you, sweetheart – I kind of lost control for awhile there…" I laid my hand on her soft, damp cheek and she placed her hand over mine. "It felt a little like I was killing you."

Alex kissed me softly and lovingly. "Michael," she murmured, "if I'm dead then I've sure gone to heaven!" Then she got that look in her eye again. "That was a beautiful birthday present – just what I've always wanted! But I have a present for you, too."

She scooted toward the foot of the bed until her face was level with my crotch and slid her hands under my ass, squeezing and kneading. My cock had shriveled considerably already, but when she began to lick at it and suck the remaining white fluid from its tip, it recovered quickly enough.

My cock was covered with my semen and her own juices, but she seemed to enjoy the combination of flavors, and I certainly enjoyed the attention. I wasn't sure I could gobble her pussy under similar circumstances. It was temporarily so soft, she was able to stuff my entire penis into her mouth and both my balls as well. She swallowed a couple of times, and I could sense my equipment edging down her throat.

Then she applied*real* suction and clamped her mouth around the base of my genitals, without biting. Her eyes twinkled when she tugged her head back, and the strain, physical and emotional, became exquisitely erotic. In less than thirty seconds, Alex found she could no longer hold all of me in her mouth.

She began to lick up and down the stem like a lollipop and I responded with more sexual energy than I would have thought possible. The head of my penis, especially, was still very sensitive from my first orgasm and the flicking of her tongue gave me a restless twitch.

"Alex, if you don't sit on it quick, it's gonna leave without you!"

She grinned and bounced up to straddle my hips. Taking her cue from my earlier method, she grasped my penis between her legs and rubbed the head briskly against her pussy. I moaned from the electricity she generated.

She settled herself onto my cock and pressed her crotch down and forward, pushing me into herself as far as she could. She moved up and down experimentally, shifting her hips from side to side. My penetration was greater than before, and since Alex was in control each movement and change of pace was a surprise. It felt wonderful.

I took one perfect breast in each hand and massaged them, finally tugging her down to me. She braced herself on locked arms, leaning forward so I could suck on her swaying nipples. I chewed gently on the little corks and she closed her eyes and hummed in the back of her throat.

My hands on her ass pressed her clit against my grinding cock, which made her lips curl back. Her back was arched, her stomach flat against mine, her breasts brushing my face. I urged her on and she flattened herself against me, her hands squeezing my shoulders. Her ass swung up and down as I moved down and up, both of us stretching to obtain the longest stroke. Soon we were slamming together, both gasping for breath, and then I felt the spasm of climax building rapidly in my groin. I squeezed her ass tightly and shot off into her steaming cunt again. Alex launched herself a few seconds behind me, gasping and shuddering. The contraction of her vaginal muscles milked the last drop of semen from me.

She let herself collapse completely, her cunt still filled to capacity. She gave a low moan that communicated pleasure, satisfaction, and exhaustion. My cock was shrinking from overwork, too, and as it withdrew itself from her, I felt my come oozing out with it. Alex finally let herself roll off and lay beside me, her knees still slightly bent and her legs apart. I slipped my arm behind her head and she leaned over and kissed me and stroked my chest.

I squeezed my cock, coaxing the milky residue out, and gathered the mixture of her juices and mine that had soaked into my pubic hair. Then I carefully smeared it across her belly. She peered down when she felt the stickiness and smiled benignly. Then she gathered a handful of the stuff from between her legs and spread it just as carefully across my stomach. I grinned back at her and put my arms around her, and held her close to me. She folded her hands against my chest and nibbled at my throat.

After a few warm minutes catching our breath and basking in the heat we had generated, Alex nuzzled me. "Michael, we need to get up and take a shower, before we get stuck together… as much as I hate to leave your arms right now. God, I love you. But I can love you in the shower, too. C'mon…"

She began sliding toward the side of the bed, trying to drag me after her. I mumbled a protest as she rolled me over on the sweat-soaked sheets. The clock read just after midnight. I knew Alex was right, but she'd worn me out and I wanted to just lie there. She finally got my attention by tugging firmly on my flaccid penis; she giggled and I moved.

We wandered the few yards down the hall to the bathroom, arms around each other's waists, hips bumping together. I turned the shower up to hot-as-hell while Alex dug out a stack of thick towels. The bathroom was already filling up with steam as we climbed into the big shower stall and closed the glass door.

We shared showers often in those days, soaping each other up and down and sliding out bodies against each other. We always loved to handle each other's bodies, tracing the curves and planes with our fingertips and the palms of our hands.

I enjoyed kneeling behind my sister and shampooing her thick hair -and I knew she enjoyed it, sitting cross-legged on the tile floor with her head leaning against my chest. That position also made it easy for me to cup her breasts in my soapy hands, to lift them and play with them, pinching her nipples between thumb and forefinger. She always enjoyed that, too.

There was something particularly romantic and erotic about sharing a lengthy deep kiss, naked under the hot cascade from the shower head, our sweat mixing with the steam, the water splashing from her body to mine and back to hers. We did that now, but there was the new, added element of fulfilled sex. No more holding back, no more being careful to maintain control. As long as both of us were willing at any given moment, we could fuck all we wanted. It was a very liberating realization. And though we were both a bit exhausted – and very stiff – we hadn't lost interest.

Alex flattened her body against mine under the spray, one arm tight around my neck and her other hand tangled in my hair as her tongue tickled my palette. Her thighs pressed against mine, her crotch grinding against my cock (which was, unbelievably, already showing renewed interest), her navel trying to form a suction with mine. Her breasts were mashed hard against my chest, as if she were trying to get inside my skin with me.
