They all smirked, and waited for another moment, then smirked again and went to their rooms, walking as they normally would. The girls raced to get their clothes off, grinning and smirking. In the bathroom, after using the toilet, they only used the bidet, and hurried back to their room, closing the door and waiting for Pierre to use the bathroom and join them. Marlie murmured:
"You did this morning; my turn, but like Monday night, except that I'm really going to, but then you can, while I sit on his face."
Catherine was a little surprised by her so directly describing how she thought they should do it. Of course, it was her turn first now, but talking about it that way? If she wanted to suck his cock first - when it was her turn - maybe just do that, since Marlie was assuming that he would lick her kitten - her pussy - while Marlie was really doing it with him? Would it be unfair for her to want to suck his cock and then also really do it with him? Could he, would he want to come three times? Or was Marlie also thinking of sucking his cock first, and then ...? She had been the one to suggest that pastis reminded her of what they both liked to taste.
They heard him close his bedroom door. Whatever Marlie suggested, whatever happened, while they waited the few second before he would silently opend their door, she felt her pussy go moist, as her thighs twitched. The door opened. He smiled at them and close it. Marlie gestured at her bed and whipped back the covers. He smiled at her with a nod, then giving Catherine a smile and gesturing for her to follow him, as he lay down. Marlie was already moving to kneel on the foot of her bed.
Catherine wondered if they had whispered about what they wanted to do, while she had been turning off the TV, but didn't hesitate to follow him. His more cock than willie was already in Marlie's mouth, as Catherine straddled him, hoping that he appreciated that her pussy was already moist. He did with a hum, as his tongue found it. She hummed in response and watched Marlie suck his cock. Oooh, she really knew now what Marlie was enjoying! Her tongue moved in her mouth, wanting to feel his cock, to feel where she knew Marlie's tongue was caressing it. Was she going to enjoy that until it let her taste what they both liked?
She moaned; his tongue was tasting her aroused kitten. No, it was now her pussy; his tongue was probing in it - almost like a cock. She moaned, forgetting Marlie in her arousal for a few moments. But then Marlie suddenly moved. Catherine's eyes opened in surprise, and she saw Marlie rise up and crawl up over him. She was going to fuck him! Of course! Her hand was guiding his erect cock to her pussy. Catherine moaned with her, as she saw her hips sink down on it. His cock all the way in her pussy, that felt so good!
Then she felt that Marlie was looking up at her. Their eyes met. Marlie smiled slightly with a nod, and then began to rock her hips to and fro. He moaned, a chuckling moan, and licked where her pussy most wanted to feel it. Then his hands slid up and held her breasts. She nodded with an encouraging moan, then thinking that Marlie would want hers to be held, would want to feel her nipples - they were so stiff! - aroused, like his fingers were arousing hers.
She reached up and held them. Marlie nodded with a moan, rocking her hips. Catherine wished his cock were moving in her own pussy, despite his tongue's making her also moan. Her fingers squeezed and twisted Marlie's nipples, doing what his fingers were on her own nipples. Then she was surprised to see Marlie's hand reach down and her fingers creep in among hers and her brother's pubic hairs. They were fucking, she thought; did Marlie want to do that too, need to? It seemed like cheating or something, wanting to arouse herself, while his cock was in her pussy, but she was!
She more felt than heard his chuckling moan and that he had nodded; he knew what she was doing; it couldn't be the first time he had felt the backs of her fingers moving on him there. If that is what they did and liked, she thought, feeling that Marlie was rocking her hips on him. Oh, it must feel good, arousing to feel it both ways like that! She moaned, imagining how it could feel.
After a few moments, she was surprised again, when Marlie's other hand slipped around her neck, drawing their shoulders closer together. Her arm pressed on her shoulder, and she began to move her hips more vigorously, not just to and fro, circling - churning his cock in her pussy! God, that must feel good! For him too, he was also moaning. Oooh! Marlie was drawing them closer, finding her lips with hers; she also wanted to kiss. If she wanted to? They did. For a moment, Catherine wondered what he would think about that, then remembering that he knew what they did it with each other.
Marlie's tongue in her mouth and her brother's tongue arousing her pussy! Arousing! More in a reflex from what his fingers were doing, her fingers continued to pinch and pull on Marlie's nipples. She wanted her own orgasm, and then they could do whatever they wanted, she selfishly considered and rocked her hips down on his mouth.
Had he read her thoughts? His fingers almost hurt her nipples, and he was licking and sucking more intensely. Her hips twitched. More, she willed; make me come - all wet on your face - and then you can really fuck your sister.
He did, making her gasp and groan, unable to continue sucking Marlie's tongue in her mouth. After he lapped up what his tongue could find, his hands and Marlies' arm almost shoved her to the side. She dropped down off him towards the wall and got her legs out of the way. Marlie moaned with a nod and dropped down on her brother.
Catherine watched them kiss and saw his hand find her breast, and then noticed his other hand slide over her ass. Of course, he was going to do that too! Even in the dim light, she could see his fingers explore and then one probe. Marlie moaned and let it, and gave another moan, when Catherine saw his fingertip disappear. Her own muscle there contracted in empathy, and she wondered why that felt good, but it did - but not for her without his finger there.
She assuaged herself that she had just had an orgasm and was going to be able to do everything that Marlie had and was, watching her hips begin to move up and down. It was indecent to watch another couple fuck, unfair to have to watch them, even if she was going to get her turn. But could he again?! Could he a second time as good as he was with his sister? They were both moaning and almost panting, his hips rocking up to meet Marlie's. He couldn't fuck her that hard, could he? He was fit - hard stomach - but do it like that again, and wouldn't it take longer for him to come a second time?
Then he was groaning softly and then grunted, and Marlie gave a pulsing moan. Their hips slapped together a few more times, and then Marlie collapsed on him. They both gasped and moaned. She rocked her hips to extend her legs, and they sighed with long, soft moans.
Catherine wondered if they did it that good every night - siblings. Could it be better with a lover? Was it so good because they were siblings? She wasn't his lover; could it be as good with her? But she wanted to fuck him. She was a little shocked at her having so directly thought that. Would he even want to again? Would, could his "petit Pierre" want to? It must now be just a willie. She heard Marlie snort slightly, as her thighs twitched. Yes, it was just a willie now, had slipped out. It was going to be all soft when Marlie moved off him and let her do it. Oh, starting by sucking it, what would that be like? Would he want her to?
She suddenly chuckled, remembering that Marlie had said that she wanted to suck his balls, but that she hadn't. She would, until his cock wanted to be sucked, and if took longer, she would enjoy that too. And if he was too tired to fuck her as hard as he had his sister, she would fuck him as hard and as long as she could, as long as she had to, to make them both come - the longer the better.
But Marlie was still lying on him, and Catherine saw his hands holding her ass, fondling gently. Despite her previous thoughts, she wondered if it was appropriate to disturb them, fair to expect that he would still want to do anything with her, want her to do anything with him. On the other hand, she couldn't leave the bed without reminding them that she was there. She rubbed Marlie's thigh lightly and heard her soft, surprised "Hmm? Um-hmm."
Marlie kissed her brother again and murmured:
"Guess I'd better find the other bed."
"Um-hmm," her brother agreed.
Catherine saw him squeeze her ass and then help her slide off him. While Marlie moved off him, Catherine wondered if she should suggest that he didn't have to do anything with her. She was still wondering, when Marlie stood up, but then he rolled towards her and rubbed his hand on the back of her knee and and began to move himself down the bed, moving his hips down level with her head, sliding his hand up her thigh. If he wanted to, she thought, no longer wondering. He did, nuzzling his face between her thighs.
Instinctively, her thighs opened and when they felt his head raise, one drew up under it, and the other one drew up over it and past his shoulder. His hand slid up on her ass, and his other one found its way under her waist. She moaned as she felt his hands grasp the cheeks of her ass and draw her hips closer and then felt his mouth find her kitten. She moaned again and found his cock with her hand.
His - her - Little Peter was just a little willie, all soft, slimy in her fingers. She had expected that, but when it was in her mouth - all of it - the taste wasn't attractive, but only for a couple of moments. If she liked the way he tasted when he came in her mouth and liked the way Marlie tasted, it had just been surprising to taste them both before she was aroused. With the appreciation that they had both come so good, she liked the taste and licked to enjoy more of it.
She hummed, and then moaned in response to what his tongue was doing, curling her hips up against his mouth. His soft willie began to grow in her mouth, more for her to lick, now not moving away when her tongue circled it, now her Little Peter, its head becoming round and smooth for her tongue to caress, and his tongue was doing such nice things on and in her kitten. She moaned again; on it, there where it felt most arousing!
