Part 1 - Fireworks

I was jealous when my twin brother Jon told me he had a girlfriend. Jon was mine, and I didn't want to share him. I couldn't tell him that, of course. I was the fast girl during high school, and even in college, when my tastes went far beyond what I could get in back seat, I never even tried to make love to Jon. We were best friends, and sometimes he was the only guy in the world I could stand the sight of, but I never told him how I truly felt.

But this woman, who he found in our sophomore year in junior college, was a threat all the sudden. Jon was a propeller-head and had as much social life as the computers he worked on. Our mother and I kept him decently dressed and made sure he had a date now and then, but when he latched on to this Daphne person, it was a surprise.

I have to admit she did him good. She was a fellow computer person, he told us. One day, he asked me to come along when he picked her up from work.

We waited for her in the mall. I didn't even know what she looked like, and I was surprised at the woman who waved and smiled as she came out the door.

"This is Daphne," he said to me. "And this is my sister, Robin." My respect for Jon went into orbit. She was drop-dead beautiful. Like me, she was of medium height, with thick, dark hair pulled back and tied with a crimson ribbon. She had a pale, round face and wore a black jacket, very short black skirt, black stockings, and flats. She wore oversized round glasses over large, violet eyes. I felt almost plain next to her.

She squeezed my hand firmly, then let go of it and kissed Jon very thoroughly.

The initial impression was good for both of us. The fact that we liked each other immediately didn't lessen my jealousy, but made it easier. We became close quickly. We double-dated (I didn't have a regular boy-friend, but I had a small stable of men who were more than willing to be seen with me). I spent time with both of them. We made a very comfortable threesome. She became my best friend.

Mom told me she was sure they were sleeping together. I knew they were, but I wasn't telling. I didn't talk to them about it either, because I was afraid I'd betray myself.

Every summer Mom arranged to borrow a friend's lakeside home over the Independence Day weekend. Jon and I were going, of course, and Daphne was invited too.

Mom, Jon and I arrived together Thursday night, and Daphne was beating on the front door by eight the next morning. When the day got warm, we ditched shorts for bathing suits. Jon had his classic trunks, I wore a high-collared, skin tight yellow one piece, and Daphne wore a thong bikini that was positively indecent. She looked very good, and I wondered again how Jon had managed to land her. It made me want to get her into bed, and I felt a different kind of jealousy.

"I think you must be the two sexiest women in the world," Jon said as he lay between us beside the lake.

"You can't count," I said. "There's one here, and she's on the other side of you." I'm far from beautiful, but I've got a killer body and I make the most of it.

"I accept the compliment," Daphne said, "and I don't think Robin has anything to complain about."

"Besides," I said, "I'm your sister, you're not supposed to notice me."

"Sorry," he said, slapping my butt, "can't help it." So maybe he did notice me. We'd shared a bathroom for years, he should have noticed something by now. I had. He could pat my rear anytime. He turned his head away and I heard the sound of his hand on Daphne's bottom. She laughed, and I looked over. His hand lingered on her bare bottom, and for a moment I envied her. But I kept watching his hand until he drew it back.

We had a barbecue in the late afternoon and debated whether or not we'd all go watch fireworks at the park on the far side of the lake. Mom decided she wanted to go, but we decided to stay. I had an idea why Jon and Daphne wanted mom to go away for awhile, but they seemed willing to let me stay. Mom seemed happy that I was staying too, probably thinking it would keep them from any sexual shenanigans. I knew better, but I wasn't telling her.

We cleaned up and sat in the shade of the porch. Mom and I read and Jon and Daphne played backgammon. About seven o'clock Mom decided to leave to find a good seat. As soon as the car disappeared up the driveway Jon and Daphne were on their feet.

"We'll be back," Jon said to me.

"Ooooh, can I watch?" I asked playfully. Jon, of course, knew my predilections, and ignored me.

"Not this time!" Daphne replied with a laugh as they disappeared into the house.

Refilling my glass from the pitcher of iced tea, I thought about her answer, wondering if she meant it. I returned to my book, but I couldn't concentrate because I caught myself listening to them. I could imagine Jon's hands on her breasts, his lips and tongue on her round, brown nipples, his fingers opening the delicate flower between her legs, finding the sensitive nub of her clitoris beneath its hood with his tongue. My fantasy was punctuated by a particularly loud moan from Daphne, and I imagined her mouth open, her tongue licking its way up Jon's erect cock, exploring the cleft at the base of his glans, then the hole at its tip, sucking it into her mouth, her head bobbing up and down as she took him deeper and deeper, his hands in her hair and on her breasts...

Unconsciously I'd been rubbing my vulva through the thin material of my swimsuit, and my orgasm was almost a surprise. I relaxed afterward, slurped iced tea, wondering how I could have either one of them. I enjoyed women as well as men, and I simply couldn't find a preference for either. Right now I felt a strong preference for both my brother and his lover.

Daphne stepped out onto the porch, in her bikini, her color high. Without saying anything, she found her glass and poured herself some tea. I smiled at her and returned to my book.

Fireworks were scheduled for 10:30, and it was pretty dark an hour earlier. We played frisbee on the lawn for awhile until it got dark, then sat on the grass by the lake, still in our swimsuits. It was pleasantly warm.

"Want to take a swim?" I asked.

"Skinny dip!" Jon said.

This caught me by surprise, but it was dark, after all, and there were no other houses too close.

"I will if Daphne will," I said.

"Well, I've got nothing to hide," she said.

"I know," I said, "you haven't been hiding it all day!" She laughed. Jon already had his trunks off. I stripped off my suit as Daphne untied her halter and slipped off her thong. Her breasts were smaller than mine, and her hips wider. I'd always wanted a figure more like hers than mine, with breasts too big and butt too skinny. I watched her ass bounce into the lake with a splash. "C'mon, Robin," Jon said, grabbing my hand and pulling me toward the water. He kept a tight grip on me until we hit the water and ran full into Daphne. We all went down in a pleasant tangle of arms and legs.

We shed our inhibitions along with our bathing suits. Splashing turned into tickling in the shallows, and it didn't seem to matter who was tickling who. Tickling turned into wrestling. I took Jon down once, and we were grabbing just anywhere to get the job done. Daphne pulled me off of him and took me down with obvious glee.

After I elbowed her off my back she decided that Jon was friendlier, and after a very quick, very touchy-feely conference, they ganged up on me. For about two seconds I was underwater with something heavy and soft on me. I barely had time to struggle against imminent drowning when they hauled me up and, amid much laughter, deposited me with a thud on the grass.

I lay on my back, spread-eagled, unable to control my own laughter, and they collapsed nearby, laughing at least as hard as me. Eventually I was reduced to just trying to catch my breath, until I noticed that the heavy breathing nearby had a different note to it. I rolled onto my side. Jon and Daphne were practicing their french kissing. They were side by side and Jon was in an obvious state of excitement.

I probably should have snuck off, but the preceding half hour of water sports had removed all traces of sanity. I crept a few feet closer to them and just watched. When their kiss ended they looked straight at me.

"Can I watch?" I asked, my voice just above a whisper.

"God, yes," Daphne said. Jon dipped his head to take her left nipple in his mouth, which I took for assent. I settled back on my knees as she moaned with pleasure as he sucked, then extended his tongue to circle the nipple.

Jon straightened up on his knees after a few moments. His cock stood out from his body like a pump handle, long and thick. In the bright moonlight I could see the glitter of a drop of liquid on its tip. Daphne got up and crept closer to him and I spread my knees against the rough, cool grass in anticipation.

The angle was bad, but I knew she had taken his cock in her mouth by the way her head moved and the way his hand curled about her neck. I scooted to the right to see better, and saw his cock slowly sliding out from between her lips, gleaming with her saliva. His pole was bigger than any I'd ever sucked, and I could almost taste his turgid flesh. I cupped my breasts and squeezed as her tongue curled around his glans. She ran her pursed lips up and down the shaft, even sucking on one of his balls, before taking first his glans back in her mouth, then the shaft all the way to the root, so fast that I almost gagged in sympathy. It didn't seem to bother her at all, and she left him in there for what seemed like a full minute, her jaw and throat working. Jon grabbed her head with both hands, his eyes closed, and when she released his cock, he began to pump his hips, fucking her mouth. I saw movement between her legs; her ass was still prominent to me, and the movement was her hand, teasing her vagina open. I dropped my right hand from my breast, leaving it almost cold in the night air, and found my own clitoris. It was already tingling with vicarious pleasure, but the first touch of my finger sent an almost painful stab through my legs and buttocks.

At my gasp, Daphne released Jon's cock completely, then grabbed it with the hand that had recently been between her legs. She looked at me with a slight smile, then looked up at him. "Do me," she said, her voice surprisingly loud.

"Sit on my face," he replied, glancing at me as if to make sure he still had his audience. Daphne rolled to a sitting position, her knees wide apart, and he lay on his back.

"You just want me to suck your cock more," she said, bending over him. Their tongues slid over each other, then she turned and kissed his belly.

"Just don't get distracted and bite down at the wrong time," he said as she swung one leg over him. He grabbed her generous hips and pulled her ass to him. The last thing I saw of his face was his tongue sticking out, its tip moving in anticipation.

Daphne kissed the tip of his cock again, and her lips and tongue moved over the shaft, but she was soon too distracted to work seriously on him.

By this time I had my middle finger deep inside myself, and I lifted one breast up to tongue my nipple. Daphne had abandoned any thought of fellatio. Her back was arched, her head thrown back, and she twisted one of her nipples furiously between her fingers. Soon enough she came with a loud gasp, sparking my own orgasm, which was just a little quieter.

After a few moments she rolled off and knelt beside him, stroking his chest and belly. Then he took her by the waist and pulled her on top of him. She straddled him, and they kissed greedily as he moved his hands over her back and ass. His cock was in shadow between her legs, but I could imagine it pressing against her pussy lips. I crept closer, my heart thudding painfully.

Indeed, I saw in the dim light, the tip of my brother's penis lay nestled between her damp lips, and I was close enough to smell their musk. I watched her hips press downward and his push upward, but his cock slid away. I saw my opportunity to have at least a little part in this love feast, so I reached down between Daphne's legs, took hold of the warm, hard cock, and aimed it again for Daphne's waiting pussy. Feeling what I was doing, Jon didn't move, but Daphne thrust downward again, and my positioning of his cock was perfect. I rested my arm on Daphne's leg as he slid into her, then too far out. I steadied it again, now wet with her juices, and once again she impaled herself on him, this time sitting up on his hips so he wouldn't slip out again. I moved back, my hand boldly brushing the smooth skin of her bottom, and sat back with my legs curled under me, sucking at my musk-moistened fingers.

Jon's hands cupped and caressed Daphne's breasts, rolling her nipples as she bounced up and down on him. He was getting closer and closer to coming, but she had other plans and stopped her movement.

"Don't stop, Daph," he moaned.

"I want you on top of me," she said, kissing him and standing, releasing his cock. Without looking behind her she flopped on her back, her knees in the air and spread wide. I saw where her head was going to land and I positioned myself underneath it. She looked up at me, but her attention was taken by Jon's thrusting cock and she reached down to guide him in.

He lay atop her, his mouth locked on hers, her hands on his ass, and his hips moved slowly. I leaned on one hand and looked down at them, my other hand resting absently against Daphne's head. As Jon's excitement increased, he rose up on his hands, his head brushing against my breast as he did so. Not breaking the rhythm of his fucking he looked up at me and licked his lips. Unable to resist his plea, I held out that breast to him and watched as he fastened his mouth on my waiting nipple. I couldn't contain my moan of pleasure as he sucked at it, sending a laser beam of pleasure straight to my clitoris. I looked down at my brother sucking my breast and saw Daphne below him, her head pillowed on my thighs, her eyes glittering in the moonlight, watching us, smiling and licking her lips.

Emboldened by my brother's touch and his lover's apparent approval, I reached down with my free hand and took hold of her breast. It was just big enough to fill my hand, and I saw her close her eyes. Out of the corner of my eye I watched one hand move from Jon's waist into the darkness between their bodies. From Jon's reaction she must have found the point of union, where his penis pistoned in and out of her vagina. His mouth left my breast and he arched his head back, grunting and groaning with the ecstasy of his rapidly-approaching climax. He cried aloud as he came, and his buttocks clenched as he thrust into Daphne as far as he could.

At that moment the fireworks started across the lake, gold, green, red and blue light spreading over us. Jon lowered himself onto Daphne. I looked up at the display, caressing Daphne's hair, and after a moment I stroked Jon's hair as well. Eventually I became aware of my legs falling asleep beneath me and tried to move them a little. I didn't really want to disturb our little tableau, but Daphne sensed my discomfort.

"Up, dear," she said softly, and Jon rose on his knees between her legs, his penis now only half-erect. He took her hands and pulled her to a sitting position, her head resting against his chest. I straightened out my legs, then wiggled them back and forth to restore the circulation.

"Show off," I heard Daphne say.

"Exhibitionist," he replied.

"Voyeur," I said, raising my hand and waving it. They both laughed and let go of each other, sitting in the grass.

"God, that was good," Daphne said. "We should do it with an audience more often."

"I liked it too," I said. I got up, shaking my legs a little more. He got up too, and to my surprise grabbed me about the waist, pulled me to him, and gave me a most unbrotherly kiss. Then he let me go just as fast, took Daphne's hand, and started toward the house. Just as big red starshell lit up the sky I saw Daphne turn and smile at me over her shoulder.

I scooped up our bathing suits and followed them.

Part 2 - The Fist

I frigged myself to sleep and woke early, feeling refreshed. I made coffee and sat on the porch in my robe.

There was movement inside, and Daphne came out the door with her own cup of coffee and robe and sat next to me.

"Hi," she said.

"Hi," I said. I looked at her, caught her looking sideways at me, and sipped. "No regrets?"

"No," she said after a moment. "None at all." I held my hand out to her and after a moment's hesitation she took it and squeezed.

"We could go on a little hike today," I said. "There's a trail I know, flat, in the trees..."

"Just you and me, okay?" she said. Surprised, I agreed.

The trail was a half-dozen miles up in the hills. I stopped in a turnout where the car would be in the shade most of the day, and pointed out an almost-hidden trail leading into the woods. The property was owned by the same people who owned the cabin and was quite private.

Daphne took the knapsack first, and we started off. After a short, sharp climb over a ridge we descended into the valley of a small stream that drained into the lake. The walk was enjoyable, with birds singing and squirrels in the trees and a light breeze to keep the woods from getting stuffy.

"Can we talk about last night?" she asked after we'd been on the trail for about half an hour.

"Sure, but let's stop first. There's a good spot by the stream up here a little way. We can stop there." I wanted to talk to her, too, as well as to my brother.

We found it about ten minutes later, a little thicket that couldn't be seen from the trail unless you knew where it was. We sat, pulled out Diet Cokes, and looked at each other.

"I've never done anything like that before," Daphne said. She looked at me, expecting an answer.

"I have, kinda. I was at a party once that turned into an orgy. There were three of us there, none with a date. We mostly watched."

"Mostly?"

I just smiled.

"It was fun being watched."

"It was really fun watching."

She laughed. "Your brother..."

"Yeah." I took a long drink, remembering my hand on his cock, his mouth on my nipple, his tongue and mine together.

"I think you wanted more from him than what you got last night." She didn't look at me.

"He's my brother, Daphne. My twin brother." I wondered who I was trying to convince.

"So you guys have never..."

"No. That was the first time we'd ever... touched each other like that."

"Well, Jon does kind of lose himself to the moment during sex." She was trying not to smile.

"That french kiss he gave me was somewhat after sex," I shot back, challenging.

"Yeah, you're right, it was."

"Daphne, you don't seem to mind that I would really like to sleep with Jon."

She laughed.

"Why should I? You're his sister. You're no threat. I wouldn't mind sharing him with you, 'cause you'd never take him away from me."

I hadn't thought of it that way.

"You're right, I wouldn't do that. Couldn't do that." I sighed. "But how does he feel about it? Has he told you?"

"I think last night was an indication. It doesn't matter if he's related to you or not, part of him wants you."

I sipped and sat for awhile. "Yeah, well, the feeling's mutual. So what do I do, jump him some night when you're not around?"

She turned toward me, pushed a lock of dark hair away from her face, and said, "Robin, I would not make you commit incest without being there to provide moral support."

"Or immoral support, whichever the case may be." We laughed hard, rocking against each other. I ended up leaning on her shoulder and didn't feel much like moving. She didn't push me off, either. I decided to take the next logical step.

"I'm queer, you know," I said.

"I wondered. Bisexual, I presume."

"I have no preferences. I take what's offered to me, if I find it attractive."

Her fingers dangled tantalizingly over my knee, their tips just brushing it.

"Am I attractive?" she asked.

"Well, yeah. Am I?" I wasn't sure who was doing the pushing here.

"I've never been with another woman before." She laughed and looked at me. "Have you heard that one before?"

"Only the last time I said it. I was a virgin six months ago. As far as other women were concerned, that is." I looked at her hand, still dangling.

"Do you want to?"

"When you touched me last night... I liked it. It excited me. I've thought about it before, wondered. I'd like to try it." Her hand landed solidly on my knee.

"You know," I said, covering her hand with mine, my heart thumping, "I learned an interesting thing at that party. Threesomes are lots of fun."

"Threesomes? Like you and Jon and me?"

"Yeah."

"You learned that at the party? Just by watching?"

"We three women were the only unattached people. The atmosphere kind of got to us."

"So you joined in?"

"No. We played together. One of the other women was quite experienced with other women. It was quite... educational. I think one with a man involved would be at least as much fun."

She was looking at me, a little shyly. I bent forward and touched her lips with mine, trying to go slow, but she wasn't too interested - her tongue parted my lips, and to my surprise she became the aggressor. Her arms went around me and she was against me, and I spread my hand over one side of her ass, curling my fingertips into the cleft as far as her shorts let me.

Her tongue explored my mouth thoroughly. I love the feeling of someone's tongue in my mouth, a warm, slippery thing, alive unlike any other part of the body. A tongue can be like a playful seal, leaping from place to place, from teeth to palate, or a probe, pushing and hard. Two tongues are like lovers, twining around each other like giraffes' necks. If they could fuck, they would.

Soon I'd lovingly pushed her tongue back to its own mouth and explored just as assiduously. I felt heat building between my legs.

The kiss ended at last. We looked at each other for a moment, and I touched her face. She dropped her eyes; she was actually blushing.

"Okay?" I asked. I was afraid to break the silence, afraid it would break the moment.

"Yes," she said, her voice barely above a whisper.

I pulled her tank top out of her shorts and up over hear head, letting her take care of getting it off her arms. She wore a sports bra, and I pushed it up off her lovely breasts. She took care of it, too, while I ran my hands over the pert mounds of brown-tipped flesh. The rest of her clothes followed quickly, and she sat cross-legged, her elbows on her knees, and watched me strip. I felt good under her eyes, an unaccustomed pride in my body making me thrust out my breasts as I exposed them to her. Naked, I knelt beside her, one knee touching her leg.

She put her hand on my leg, leaned over, and ran it up my thigh to my hip, up my side to my right breast. She tried to cup it, but it overflowed her hand. She got on her knees and moved as close as she could get, one knee between my legs. We embraced, belly to belly and breast to breast, kissing, and this time my fingers were deep in the cleft of her ass. How deep would she let me go? My forefinger found the rim of her anus, then the center, and she gripped my waist harder, her kiss insistent. I pulled my finger back, saving it for later.

I started kissing my way downward. The downy skin of her cheek became moist beneath my lips, and she gasped as I nipped at her earlobe. Then I drew my tongue down her throat and into the hollow beneath her collarbone, tasting sweat-salt on her skin. Then I reached her breast. I licked it all over, all of it except her nipple.

She arched her back, breathing heavily, and when I judged the time to be right (and when I couldn't stand waiting any longer myself) I sucked as much of her nipple into my mouth as I could. She gasped and grabbed my head, and let out a little grunt as my tongue stabbed at her. Then I let it go and alternated circling her nipple with my tongue and sucking at it. Eventually I licked my way across to her other breast and did much the same thing.

This play eventually dissolved into more kissing, and then she wanted to do it to me. I lay back on the rough grass, twitched my shoulders around a little to kill an itch in the middle of my back, and let her go to it. She straddled my hips, and I ran my hands from her knees up to her breasts, which hung down delightfully over mine as her tongue explored the hollow of my throat.

I don't like my breasts all that much most of the time. They're too big, attracts lots of attention (some of it unwelcome) and give me backaches (all of them unwelcome). The only time I like them is during sex, whether it's just me masturbating in bed at night or with someone else. They are so sensitive, it's sometimes like there's direct link between them and my clit. I've made myself come playing with my breasts alone.

So I started getting pretty excited when Daphne put her nose right between them, then gathered one in each hand and squeezed them together. I felt her take a deep breath in there, felt her licking and nuzzling. I held fast to her hips, and opened my eyes only when she let my breasts go and straightened up for a moment. We looked at each other and smiled.

She bent over again, took my left breast between both hands and went to work on my nipple.

Her mouth on my breast was exquisite. She seemed to devote all of her attention to it. The heat between my legs was like a fire, the tingling building with delicious agony in my clit. My vagina felt like a running faucet, and she was my only relief. Then she did the unexpected; she made me come.

She knew what she'd done and eased off her attentions, laying on top of me. I wrapped my legs and arms around her.

"You really came?" she asked, her mouth close to my ear.

"Oh, yeah."

"Jon always seems to like sucking on mine... I wanted to see what he experiences."

"Did you like it?" I asked.

"Yes!"

Daphne was in an exploratory mood now. Her fingers were making their way down my ribs, across my belly, to the edge of my pubis. Her eyes and mine had followed their progress southward, and when she stopped I spread my legs and moved my hips, urging her on. I found her looking at me, and she licked her lips and kissed me. She seemed nervous. I put a hand in her hair and tried to encourage her by kissing back. Somewhere in the middle of the kiss her hand slid between my legs and her fingers explored, first tentatively, then with greater assurance. I knew what she was thinking; it was very strange to touch another woman's sex for the first time, feeling things that are very familiar, yet receiving only half the sensation.

She had no trouble finding my clitoris, which she touched only briefly, as if wanting to prove she'd really found it. Then she traced the folds of my inner lips and finally ventured a finger inside, followed quickly by a second. Her two fingers filling me like a slender cock. I wanted more. If she had any uncertainty of how to please me, now was the time to end it. I broke the kiss.

"I want your tongue down there," I said. She looked down at where her fingers were buried to the third knuckle inside of me, and positioned herself between my legs. She removed her fingers from my vagina, and put her hands on the insides of my thighs, and pushed to spread them further than they were already.

She blew gently on my vulva, inhaling my scent. Then, just as I was about to give her head a push, she dove in. She lapped at my labia, tasting the juices coming from inside me, and finally unhooded my clit.

I don't remember much after that. Her tongue was as magic to my sex as it had been to my mouth and nipples. I remember taking a hank of her hair between my fingers and rolling one of my nipples with the other hand, and the waves of pleasure that rolled over me like flowing lava. I remember being very noisy when I came. I remember tasting myself in her mouth when we kissed afterward. She rolled onto her back.

After regaining my equilibrium, I bent down and kissed her breast, then rubbed my cheek down her thigh. She seemed to know what I wanted her to do without any words. I lay on my back and she lifted her leg over my head, and I took her lusciously wide hips in my hands and pulled her back and down so her pussy was positioned just above me. Looking between her legs, I saw her breasts dangling, and her head turned back to see what I was doing.
