Ellen had felt her own delight at her son's ready agreement to pleasure her again-a delight that had grown even more when he proved to be more than willing to do so orally. It had taken only a few moments to settle herself into a chair and assume a position almost identical to the one she'd seen Carla in. Only a few seconds after that, Robert was seated on the floor in front of her. No encouragement was needed for him to lean forward and get his head within just a couple of inches of her womanhood, and she didn't mind that he took a little time to look at the area between her wide-spread thighs before moving even closer and slipping his tongue between her slick labia. It took only a very few minutes for Ellen to decide that her son had done a fine job of learning how to please a woman with his mouth when he'd used it on his sister: he used his tongue on her erect clitoris with a combination of speed and pressure that aroused her tremendously. He didn't focus his attention just on that area, however; he went on to use his lips to softly "nibble" on her labia, and lick and probe her opening with his tongue. Then he took it a step further by reaching up and taking her breasts in his hands, caressing and gently squeezing them and toying with her erecting nipples.
Robert almost couldn't believe it when his mother had asked him if he was willing to help her have another orgasm, and that she wanted him to use his mouth on her. His enthusiasm for the idea was great enough that it actually took a couple of seconds for him to get control of himself enough to answer that he would. Once he was seated in front of her, he had to see for himself how she was similar to or different from how Carla's genitals had looked. That close to her, he could see that his mother's bush was a medium-sized wedge of black that started just a couple of inches above where he knew her pubic bone was and quickly faded when it reached the bottom of her mound. His hand had told him it was soft and thick, and he found that he could see that it was shorter than he'd expected: her slightly erect clitoris was visible at the top, and her labia had formed a part in it. Looking closely, he saw that his mother's inner lips were longer and thicker than Carla's had been. They were somewhat dark with her desire, and at the bottom, it was plain as could be that they were already wet and slippery from her oils
— some of which, he noted, had trickled a short way down the inside of one of her thighs. His face that close to his mother's crotch, he didn't have any trouble making out the same scent he'd had on his hand after he'd used his finger in her; he found it just as appealing then as he had before, and made no effort to resist the temptation to lean forward and sample it again.
Vic hadn't thought that he'd be able to get hard again so soon after the blowjob he'd gotten from his wife, but it was looking more and more like that wasn't the case. Not only was his daughter doing a damn fine job of giving him head, the sight of his stiffening cock disappearing into her mouth while it happened was proving to be more than sufficiently stimulating. He wasn't fully erect yet, but Carla's efforts were definitely moving him that direction.
Carla didn't know about the male limitation of how soon they could respond again after having a climax, and wouldn't have cared anyway. She had her Daddy's dick in her mouth just like she wanted, and was steadily getting him longer and harder… and that was all she needed to be happy.
Ellen wasn't in any condition to think about much of anything: Robert's busy tongue and mouth on her pussy (and what his hands were doing with her breasts) simply felt too good and were too arousing for her to have much interest in anything except having him keep going with what he was doing.
For his part, Robert didn't know how life could get any better. What pleased him the most was the fact that his cock was starting to get hard again because of how aroused he was getting just from what he was doing to his mother. Then, in addition to keeping his hands busy on her warm mammaries, he could feel his mother's soft bush against his upper lip after he'd put his whole mouth over her exposed clitoris and begun a gentle rhythmic suction-something that had her arching her pelvis up and making almost continuous noises of pleasure. He'd already lapped up all of the juices that were available, and even tried to worm his tongue into her woman chamber to see if he could get more of them that way.
He couldn't, but she'd certainly indicated that she'd appreciated the attempt.
Victor could only stand there, his eyes locked on the sight of his daughter's head slowly moving back and forth as she slid her lips along the shaft of his manhood. He was almost fully erect, something he hadn't considered possible when he'd told Carla that it was okay with him if she wanted to try to make him "feel good". Her hand was cupping his balls, and part of the thrill he was feeling was in response to the way she was so gently and carefully rolling them in her hand after she'd tenderly explored their size and shape within his scrotum. Looking past her face, he could see that the peaks of her breasts were puckered and her nipples standing tall and proud… letting him know that not only did she enjoy what she was doing, but that she was excited by it. Returning his gaze to her face, he was still impressed and amazed at how dedicated she was about pleasuring him: every so often he could feel the end of his cock touch the back of her throat, but not once did she give any indication that it bothered her in the slightest.
Carla was dedicated to pleasing her Daddy-for the simple reason that she figured if she got him hard and excited, it might be possible for her to get him to fuck her. She actually enjoyed what she was doing, not just because having his cock in her mouth aroused her, but because she loved him and it pleased her to be able to show him her love that way. As she'd gotten him closer to being completely hard, she'd had to let some of his manhood slip from between her lips because there was simply so much of him. But once he was hard enough that she figured she could start moving her mouth on him, she'd made up for that loss by sliding her lips far enough down his shaft that she felt him touch the back of her throat. That hadn't felt comfortable the first few times it happened, but it was brief enough that she was able to control her reaction and get used to the sensation. Once she'd done that, she was able to keep his member there for longer and longer as she learned how to control her breathing. She didn't know why it did, but she was sure that having the end of his penis touching the back of her throat aroused HIM… enough so that he began to get even longer and harder the more she did it.
Ellen felt disappointment when Robert pulled his hands from her breasts, but it was quickly replaced with joy when she felt him wetting his finger with her juices, followed by slipping his rigid digit through her opening. It didn't take but a second for him to come into contact with that magical spot she found so pleasing, and begin rubbing and pressing against it once more. She was already incredibly aroused by the things he'd been doing, and the added stimulation from what he did with his finger only ratcheted her desire to greater heights.
Robert had taken his hands off his mother's tits only because his arms were getting tired, but once he'd lowered them, he quickly got the idea of using one of them to get her even more worked up than she already was. Then he got another idea, and used the free hand to gently open up the cleft of his mother's sex; that left her erect clitoris fully exposed to his tender mercies.
If it weren't for the fact that his cock felt like a steel bar sticking out, Vic wouldn't have believed that he could get another erection as quickly as he had-and silently gave thanks to his daughter for giving him reason to want it to happen, and providing the stimulation that made it possible. She'd not only managed to get him fully erect again, but the way she was using her mouth had him feeling that there might even be another climax not too far in his future.
