With her father's hands moving on her again, Carla promptly started trying to think of something-
anything! — that would get him to touch her where she wanted him to. She'd once accidentally heard some older boys talking about something they called "blue balls"; when she'd asked one of her friends what it meant, discovered that it meant the boy had gotten aroused for too long without having a climax. Just then, she felt a considerable sympathy for any boy that had that happen to him because if there was a female equivalent to it, she had it!
Ellen had reached the point that she couldn't have said anything to Robert if she'd wanted to: the pressure she felt was so great, and she was so close to her release, that all she could do was hold still and pray her son didn't stop what he was doing.
After his experience with his sister, Robert had some idea that something was about to happen with his mother. Even so, he wasn't anywhere near prepared when she stopped the slow arching of her pelvis and froze in front of him. He heard her start to groan, only to have the sound cut off at the same time he felt her pussy clamp down on his finger. He was surprised by the force being applied, and surprised even more when he felt her pussy relax slightly before beginning a rhythmic clenching that ran from where her opening was clenched around his finger toward the end before starting over again. In addition to all of that, Robert could also feel her juices begin to flow out and wet his hand; he'd never even suspected that a female could get THAT wet inside.
Vic had fully turned his attention back to running his hands over as much of Carla's body as he could-
even going so far as to start kissing her again so there wasn't any excuse for him not to play with her breasts some more. It had been long enough since he'd gotten the blowjob from his wife that he could feel his cock starting to get thick and heavy again in response to the sensation of Carla's body under his hands. He'd been toying with one of her nipples and started to move his hand down so he could reach around and hold her ass again when she put her hand on top of his and started moving it in a different direction. He wasn't paying much attention to what she was doing until he felt his hand cupping something rounded and slightly furred. When he realized that Carla had put his hand on her mons, he pulled his head back and looked at her in concern. He could see the pleading look in her eyes and hear the wanting in her voice as she told him "It's okay, Daddy. I… I'd like it, even."
Terrified at the prospect of how he might react, Carla simply couldn't think of anything else to do other than put his hand on her pussy herself. Only the things that they'd already been doing together gave her any hope that he'd leave it there, and the prospect of him doing anything more was little more than a dream. Much to her relief, he'd hesitated only a moment before kissing her again while leaving his hand where she'd put it. A little bit later, she'd been delighted when she felt him starting to move it slightly: first it was just so he could cup her mound a little better; but not long after that, he'd wiggled his finger a little bit so that it slid into her crack some more. Then he'd done it again so that his finger was holding her inner lips apart. After that, she could feel the palm of his hand start regularly pressing against the hood of her clitoris; and the final act had been when he'd curled his finger slightly and begin gently pressing against her opening-where she just knew he HAD to be able to tell how incredibly wet she must be!
With the end of her orgasm, Ellen wasn't sure whether to be grateful or not that Robert had discovered that spot inside her; the orgasm she'd just had left her feeling nearly as weak as a kitten. Feeling Robert's finger still inside her, she reached down and took his wrist, holding his hand steady as she carefully lifted herself off the source of her recent pleasure. The way she felt just then, she decided that her best bet was to get off of her shaky legs and simply kneel on the floor. She was grateful for the help she got from Robert, and managed to tell him "Thank you"-realizing too late that he might think she was thanking him for the orgasm, and not the assistance he'd provided in getting her safely to her knees. Smiling to herself, she had to admit that he certainly deserved her thanks for an orgasm like that!
Robert remained standing in front of her, and when she raised her head, she found herself facing her next temptation… one she readily gave in to, feeling her mouth start to water as she raised her hands and leaned forward.
Naturally, Robert didn't have any idea what his mother's orgasm really meant to her, since he wasn't privy to the goings-on (or lack thereof) in his parent's bedroom. So when he'd heard her thanking him, he didn't have any reason to think that it was for anything BUT helping her to the floor. It was something he was actually glad to do, since he could see that she was having trouble standing after what she'd just been through. Looking down at her once she was on her knees, he saw that her head was hanging down; that seemed like the perfect opportunity for him to find out if his mother's pussy juices were anything like his sister's. Turning his body slightly to try and block what he was doing from her view, he moved his hand to his face. It took only a brief sniff for him to learn that his mother's lubrication was a bit muskier than Carla's, but not less appealing. Sticking his finger in his mouth, he learned that her oils were a little thicker, too, and tasted almost exactly the same as they smelled. It was only a few seconds work for him to get his finger, then the rest of his hand. cleaned of any trace of her.
He was just starting to wonder what else was going to happen when he felt a hand wrap itself around his hard cock just ahead of something incredibly warm and wet engulfing the head.
Carla had readily cooperated while Vic got the end of his finger wetted from the abundant supply of her lubrication, and then carefully worked it through the tight ring leading to her vagina; she even tried to spread her legs for him in the process, making it easier for him to discover the obstacle of her hymen not far inside. Vic found himself both pleased and excited with the thought that his daughter was still a virgin. Removing his invading member from her virginal opening, Vic used the oils on the end of it to lubricate her erect clitoris as he tenderly began to stimulate it with a random mixture of caresses, circling it, and simply pressing against it. As he was doing those things, he could hear his daughter's breathing get faster between soft moans of pleasure at what he was doing. With his hand busy between Carla's thighs, he didn't have any objections when he felt her small, cool hand softly grasp his manhood.
Carla was nearly ecstatic that her daddy was touching her the way he was. Even better was that it felt so wonderful-better, even, than when she did it… or what Robert had done, for that matter. She was sure she was practically dripping, she'd gotten her so wet; when she happened to open her eyes and looked down to see that his penis had gotten longer and thicker, she didn't even think about it before reaching out and taking it in her hand and feeling it twitch in response. With only the experience of having Robert's penis in her hand, she started stroking the larger mass in her hand slowly and carefully.
It took a little bit before she was sure that she was getting it right from the way it began to grow in her hand even more. She continued her efforts to encourage it to get even bigger as she divided her attention between the mass of meat in her hand and what her Daddy was doing to and with her.
With her fantasy of sucking her son's hard cock having come true, Ellen dedicated herself to enjoying the reality of what she was doing-and to trying to give Robert the kind of pleasure that he'd provided her. She was old enough that she'd starting having doubts about her age and attractiveness, and after witnessing what Carla had done with Robert's cock in her mouth, Ellen also felt a need to prove to herself that she was still young and vibrant and sexually appealing; so she was taking her time and doing her best to get her son as aroused as she could, determined to make his climax as strong as possible so he'd remember what SHE'D done to him instead of what he'd experienced with Carla.
