I woke to soft giggles.
I had been up too late again. Claire, my French lover, was due for a photo-shoot in the Riviera, one which I could not attend. That chaffed, but she made it up with a night of wild sex. Dimly - but warmly - I remembered how the insides of her ass slid around my dick, squeezing but slick from oils I had rubbed all over her.
I heard a giggle again. I tried to open my eyes, but the sunlight coming through the balcony door was too bright. Way too bright. I pulled the sheet tighter over my shoulders and tried to burrow into the warm, soft flesh in front of me.
Slowly it dawned on me that Claire was gone already. If the sun was up, she had been gone for hours. Finally, I smelled Natalie, my younger sister. Her shampoo brought the scent of fruits and the outdoors. I loved that smell. Now, her damp hair lay only inches from my face.
Nat was curled in front of me, which meant I was spooning her. I had my arms around her, the bottom one beneath her neck, the top one under her upper arm, reaching past her top breast to softly clutch at the other. Had I thought her Claire in my sleep? Why hadn't she slapped me away? If I was behind her, and the soft warmth of her body pressed against me, that meant the hot, damp flesh around my erection must have been her ass-cheeks after a shower. I felt a bit of give around my head.
I was jutting into my sister's crack, my cock twitching right at her anus.
My erection throbbed, and Natalie giggled again.
So why was she letting this persist? She had squeezed my dick for Claire a few days ago, in the wildest sex I'd ever had up until last night. Claire had paid her back by rubbing my cock in Nat's pussy and making me cum over her open sex. Most of the time, it seemed only a matter of time before Natalie and I were fucking, yet she had resisted, giving herself only to Claire.
What had changed? Had anything? Maybe it was all in my head.
Another twitch of my prick spilled slick pre-cum against her ass, and elicited yet another giggle. I snuggled closer to her back, determined to enjoy as much of this closeness as I could. Her dark hole, even without insertion, felt heavenly around my cock.
Natalie sat up. My dick slipped up through her butt-crack and onto her hip, smearing a trail of my slime. My sister looked back at me over her shoulder, grinning wickedly, then got up out of the bed.
"Where are you going?" I called after her as she left Claire's bedroom.
Natalie stuck her head back through the door.
"To the bathroom, to relieve myself, so I don't let you sodomize me."
Mmmmm. I almost ejaculated right there, hearing her say that. I sighed. So close, so sinful.
I stroked myself absently for a few minutes, until she bounded back into the room and hopped onto the bed. She was clothed, and her hair was damp, which meant I had dozed off. I didn't remember cumming, but my spend made a puddle on my hip and streamed down onto the sheet beside me.
"We need to go," Nat said, staring at my limp prick as the pearly goo trailing from the head to the puddle. She had seen it before. Hell, Claire had jerked me right on to Nat's vagina. When she looked at my withering erection, her face turned soft, still, unreadable, with her lips parted just so.
"Where? Why?"
"I have to meet someone. It's for a job. Claire set it up, so let's go."
Well, if Claire set it up...
"I suppose," I said. "Let me up, and I'll go take a shower."
"Good," she said, "because your breath smells like Claire's ass."
"You ought to know," I snapped back as she rose up onto her knees. Nat slid one finger through the semen on my hip, and lifted it to her mouth as she climbed off the bed again. I stared after her, watching the swish of her ass as she moved out of the room once more. I grabbed my newly hardened erection and followed her out and towards the bathroom.
Once cleaned up, I followed my sister down to a café, where we sat, sipping latte's.
"You're in love with Claire, aren't you?" she asked me.
I shrugged. "I love being with her, if that's what you mean. Why?"
She shrugged back. "You look really happy with her."
I squinted at her. "So do you, since we're on the subject." I thought back to her dipping her finger in my cum and tasting it. It wasn't something she had done with Claire. It was on her own. Mmmmmm.
Natalie blushed. "Does that bother you?"
I leaned in close to her. "You've seen first-hand exactly how much it bothers me."
Her blush deepened.
"Why all these questions? Is something bugging you?"
Nat tipped her head towards me, put her nose against my neck, behind my ear. "It's nothing, bro, except I wanna make sure we're cool. Claire turns me on. You turning her on turns me on even more. Her turning you on even turns me on a little. I like our setup, but I don't want you to feel forced into anything."
I was about to tell her how truly awesome I thought our arrangement, but a woman's voice interrupted us. She said, "excuse me, please," and when we looked up, we found ourselves meeting the eyes of a short, dark-skinned French girl. She might have been twenty-four, but she looked eighteen.
"Are you Natalie," she asked my sister. Her brown eyes were huge. Her nose was a little wide. A little flat. African ancestry, and cute as hell. Her lips, likewise, were thick, dark, and luscious. Her skin was a creamy brown color. I can't describe how exotic and beautiful she was. The girl wore a white blouse she had buttoned only once, right between her small but perky breasts, and a thin cotton skirt that went down lower in the back than the front. I found myself following the shallow groove from her sternum to her navel with my eyes. What would she smell like? What would she taste like?
"Yes," Nat said, and got to her feet. I joined her. "I'm Natalie, and this is..." she paused, and I could hear, 'my brother,' on the tip of her tongue. Instead, she finished with, "Jon."
The young woman smiled at me. "Jon. Like Jean, but not. I love that name."
Her accent was a little heavier than Claire's, but I found I enjoyed it all the same. Her eyes were warm, inviting, as if I could lean across the table and kiss her any time.
"I am Monique," she continued, I think more for me than Natalie. "Claire said you'd be perfect, and I can see she was right. Are you ready to go?"
"I want Jon to come with us," Nat said.
Monique eyed me up and down, then smiled wickedly at my sister. "Oh, most definitely."
Claire's friend Monique led us to a small, electric-green Citroen parked not far away. A man sat in the driver's seat. He was older, with greasy hair and a matching black mustache. Monique tried to get Natalie to sit in the front, but she would not, so the three of us crowded in the back. Once we were underway, Nat leaned her head on my shoulder.
"You make a cute couple," Monique told us. Neither of us said anything to correct her. How far would Natalie go with this game?
"Were are we going?" I asked, finally, when I could take the suspense no more.
"Claire has rented an estate for the day," Monique told us. "We'll take the pictures there."
"Pictures?"
She laughed.
Natalie leaned close to me, put her lips against my ear. My cock twitched at the subtle but erotic contact.
"Monique and I are going to pose for pictures on this country estate. Claire was supposed to do it, but she had that trip south, so I'm filling in for her."
"Filling in," I said, slowly. "As in, as a model?"
She grinned. "Sort of."
Monique leaned across Nat to put her hand on my leg. "These will be - how shall we say...erotic - pictures."
I gaped.
"Close your mouth, dear," Nat told me.
Monique grinned. "Ah, yes, your girl will be posing naked with me. What do you think of that?"
I glanced at Natalie. Six months ago, I'd have never thought I'd have seen as much of her as I have. Hell, I certainly never imagined the things we would be doing in Paris.
"So, is this for a magazine? Online?"
