Michael Smith - Siblings

Bill and Alex had converted the back of the station wagon into a playpen now, and had spread out the two or three thick blankets we always kept in the car. I wasn't sure exactly what they were doing back there, but Marianne was staring entranced past my shoulder and a deep flush was creeping down her torso – partly lingering shyness and her own lively imagination working on what she was watching, but mostly her own sexual arousal, the flames being fanned in her by whatever activity my sister and her date were engaged in.

I hooked a thumb over my shoulder and raised a questioning eyebrow. Marianne scrambled off my lap, tits bouncing, and climbed over the seat into the back, being careful not to step on anyone. She sat waiting with her legs crossed as I followed her.

Bill and Alex were in a '69' position with her on the bottom. My sister had her mini up around her waist, and her panties, if she had worn any, were not to be seen. Her face was framed by his pubic hair and she obviously had his entire cock in her mouth. Bill's head was buried between Alex's widespread thighs and he was industriously pushing his tongue up her cunt. They were oblivious to us and everything else except themselves. Marianne was trying not to watch them – out of misplaced modesty, I suppose – but I gently turned her head toward the undulating bodies eighteen inches away.

"Don't be embarrassed, Marianne – it sure doesn't bother THEM that we're here! Don't you see how much fun they're having? How much pleasure they're giving each other? Nobody gets hurt and everybody gets off. What could be better than that?"

She seemed to think about it as she watched – apparently forgetting that she was already half-naked herself. Alex was now concentrating on sucking the head of Bill's cock, and I massaged Marianne's breasts as she continued to watch them, fascinated now. Her hand strayed to my crotch and began stroking my cock though the denim. I'm not sure she was even conscious of what she was doing. I stifled a groan. Watching my sister suck a cock while I was being fondled by my date was having its effect.

I stroked Marianne's inner thigh and her attention flicked back to me. She realized where her hand was and smiled as she squeezed my cock. Then she popped open the top button of her shorts and lay back invitingly. I quickly unzipped her shorts and slid them and her panties down her legs and off her feet. Another surprise: Marianne, with her electric body, full breasts and hips, and lush hair, had shaved her crotch completely bare!

I was more aroused by the sight of the utterly exposed crevice leading to her cunt than I would have been by a mat of pubic hair. I looked back at her flushed face and dilated eyes and grinned my pleasure; she blushed even more. I was certain, then, that she had done this especially for me, hoping we would get this far, and letting me know at the same time how vulnerable she was willing to let herself be with me. She slowly spread her legs and pulled her knees back, and her moist clitoris reflected the light from the movie screen; her dazzling body showed not a single hair below her eyelashes.

It took me less than a second to bury my face in her smooth, sweet pussy. I was peripherally aware that Bill and Alex paused for a moment in their exertions to watch us; they both grinned and returned their attentions to each other. My tongue was busily probing Marianne's pussy and her hands clutched at my hair, pushing my head closer. I knew this was her first time for any kind of oral sex, too, and she was obviously enjoying it. Intermittent tremors coursed through her thighs and across her stomach and her feet pressed against the sides of my ribcage.

After a few minutes with my tongue inside her, she tried breathlessly to reach under my body. "I want to- to hold you- your cock! C'mon…!

I had already undone my belt and lowered my zipper, and now I pushed my jeans off. I tipped Marianne on her side and curled my body around so she could reach what she wanted. I was erect now, and she had no difficulty getting her hands on my cock. She started rubbing it vigorously up and down, but I quickly stopped her. Many girls make that mistake; they seem not to believe a guy could, or would want to, build up to a climax step by slow, calculating step.

"Just touch it, stroke it, all over – not so hard, okay? Don't be afraid to use your tongue and your mouth, Marianne, please? Close your eyes and pretend it's a stick of candy."

She obviously was eager to return to me the experience my mouth was giving her, but was unsure how to manage it. She began by holding my cock like a dagger and kissing the head and touching the tip of her tongue to it, but after a minute or two she grew more courageous and took the head into her mouth. I held my hips still while she figured out what she was doing, but at my end of our world things were a lot more active. My head was pushed up between her thighs and my mouth was playing catfish on every bit of flesh within reach. Her aroma and the taste of her was different from Alex, more pungent and spicy, but just as exciting. My hands squeezed her ass and stroked the small of her back, and my fingertips, gliding lightly between her cheeks and across her asshole, made the surrounding muscles quiver reflexively.

"You like that, huh?" I mumbled.

"Oh, God…" she moaned. "You have no idea!" Oh, yes, I did. Her tongue moved up and down the shaft of my penis and she licked and sucked lightly at my balls. She seemed to have shed the last of her nervousness and embarrassment in the heat of her growing passion. The juices were flowing in her cunt and the aroma of sex within her was much stronger.

I wondered briefly what her reaction would be if I could time-travel back to yesterday and tell her that she would soon be naked in the presence of three other people, with a guy's testicles in her mouth.

But there was something I had to know. I managed to partly sit up with one arm wrapped around her hips. She came up to the same position, so that we were wrapped in a ball together, hands busy with each other's bodies, our faces only a few inches apart. She had a kind of wild look in her eyes, like she had put all her inhibitions on the shelf for the evening.

"Marianne," I said in a low voice, "I don't want you to take this the wrong way, but… are you a virgin? I mean, you're absolutely beautiful, and I*really* want to have sex with you, but I don't want to push you farther than you really want to go – I don't want you to have regrets later…"

I was stroking her clit as I said this, but I still meant it. I was pretty sure this gorgeous girl, whom I had stupidly overlooked, had no illusions about what we were doing being "love," and I wanted to make sure we would remain friends, at least, whatever else might happen. If she was simply temporarily out of control, I had to offer her an escape hatch, out of respect for her and myself.

She squeezed my cock and stretched it toward her. "Michael, do you know how many other guys would ask a question like that at a time like this? None! I can't believe you'd even think about it – but, no: I'm not a virgin, just barely, and tonight I want you to fuck me stupid! And I won't have any regrets tomorrow. This is what I want, and I'm ready for it – right now! Mostly because it's you I'm with. Even if I*were* still a virgin, I'd pick you to pop my cherry – do you understand that? You're a very sweet guy, Michael, and I really do like you, and I trust you, too. What more could I ask for in a lover? Now, can we please stop talking and go on with what we were doing? Please?!"

She pressed her mouth hard against mine and wiped her tongue across the front of my teeth. She was radiating more heat than a homecoming bonfire. How could I have worked next to this girl all these months and never suspected the dammed up sensuality within her? Well, that dam was about to burst!
