Susan stopped abruptly just as Alan was hitting an erotic high. Sitting back up, she asked him, "Since you promised to be so good, do you mind if I... I feel so embarrassed to say this, but I'd like to, to ... put my hands down there. You know, on my most private place."
She knew that was against her own rules, but she was so very turned on that she couldn't help herself. In fact, she'd already been touching herself there occasionally, but she hoped that she'd been surreptitious enough that he hadn't noticed. She thought that if she got his okay, that would make it more permissible somehow.
He was extremely grateful that she was taking a break from her blowjob, since that allowed him to retreat from the brink. He waited some long moments before he responded. Finally, after getting his wild panting under control, he said, "Well Mom, I think it's a given that I'm going to shoot my cum all over your beautiful body."
"Yes. And?" She resumed jacking him off. She would have much preferred more sucking, but she needed her mouth to talk until their discussion had ended, and besides, she needed to give her tongue a break from all the licking and her jaw some relief from all the sucking.
"Well, we got lucky the last time and none of my cum got on your panties, but I think you should take them off just to be safe, don't you? Besides, the house 'no underwear' rule really requires it."
She gave him a naughty grin. "What an excellent idea! There's no telling where your sperm shooter is gonna hit me next." The concern over him getting his cum on her panties was absurd because they were already soaked from her own juices, even though she'd put on a fresh pair while he was sleeping, immediately after her masturbatory shower. Still, she liked having the fig-leaf excuse much more than having no excuse at all. She immediately pulled her panties down and off her legs, then threw them across the room. All the while she kept one hand stroking Alan's erection.
For a moment Suzanne froze in fear, with her heart nearly thumping out of her chest, because when Susan tossed her panties away she had partially turned so that she almost could see the open door. Suzanne decided that she was risking too much by keeping the door open, even if only an inch, so she pulled it almost closed. The razor-thin crack that remained still allowed her to hear almost everything that was happening.
Recovering from her fright, she thought, Phew! That was too close! I'm still reeling in total disbelief! Susan just took off her panties?! Pinch me; I must be dreaming! But I'm cursed too. I get to see her perfect body in the nude, which I've longed to do for years, and then I get to drink in the sight for only a couple of seconds before I have to close the door. Maybe I'll just take one last little peek... No! I can't. It's too dangerous; I can't risk ruining all my plans! What if she were to see me? In fact, even listening to them like this is dangerous. I really ought to go. ... Well, in a little while. This is too great to miss!
Susan looked at Alan's bugged-out eyes staring at her bush and grew a bit concerned, so she covered it with one hand and said, "Son, you're not thinking of you-know-what, just because your busty mommy is totally nude and jacking off your hard cock, are you?"
He answered, "Mom, I promised I'd be good, and you know I keep my promises. But can't I look? You look so sexy down there."
"Nonsense. It's a big hairy mess. You don't want to look there." But even as she told him to look elsewhere, she was grinning madly.
He could tell that she was so horny that she actually wanted to show off her pussy, so he said, "Come on, Mom. Please?"
That wasn't an excuse at all, but even so she wavered. "I don't know. It's embarrassing! The problem is, it's all, well, kind of wet and sticky down there."
"So what? You know what that means to me? That's a sign of your love. It makes me really happy and proud to see you wet down there. It just shows what a caring and loving mom you really are."
"Really?"
"Really!"
In fact, he couldn't really explain how her wetness was a sign of caring and love if she had challenged him, but it sounded good anyway and he had realized that Susan wasn't thinking logically. Hearing that, she took her hand away from her pussy.
"Oh, WOW!" His eyes bugged out in genuine awe.
She asked shyly, "You're not grossed out?"
"No way! It's beautiful!"
Very pleased at his apparently sincere reaction, she spread her legs wider to give him a better view. However, her hand hovered nearby, ready to cover her pussy again at any moment.
Still feeling bashful, she asked, "How does it compare to Suzanne's?"
He noticed that her pussy and bush looked almost exactly the same as Suzanne's. Maybe Suzanne's clit was a little bigger and her lips were a little pinker, but that was about it. Their hair color was almost exactly the same there too, except for Suzanne's reddish tint. Both bushes were thick and full, but nicely trimmed. Dammit, one day I just know I'm gonna get to know that secret place. I just know it.
He finally responded, "Mom, you know Suzanne is like some kind of unbelievably perfect goddess, right?"
She nodded.
"Well, hers looks just like yours. That means yours is unbelievably perfect too."
She smiled and turned away, pleased as she could be. "Awww. You're just saying that."
He suggested as he nodded at her pussy, "Don't be afraid. Touch it. I wanna see you play with it."
"Well, okay." I can't believe I just said that! What kind of shameless hussy am I turning into?!
However, even as she was chiding herself, she brushed her fingers up and down her soaked slit. Curiously, she kept on complaining, "But really, I feel a little guilty. Suzanne says that it's no sin for women to masturbate, but deep down it feels wrong. I'm so used to thinking it was a sin, you know? In the Book of John, it was said that-"
Before she could get started quoting scripture, he interrupted, "Mom, you're not really masturbating; don't think of it that way. You're providing visual stimulation. This is all part of helping me. Things like watching you play with your pussy or shake your rack, it all helps keep me hard so I can have my orgasms after prolonged stimulation, and do it six times a day, just like the doctor ordered."
The idea that he needed help to stay erect while his naked centerfold mother was jacking him off was absurd, but again it was the fig-leaf Susan needed for her own peace of mind. "Well, if you think it helps..." She began fingering her labia in earnest.
However, she realized she'd be having double the fun if she was stroking her son's boner at the same time. So she shifted positions and used her other hand to do that too.
Pretending to be clueless, he asked, "What's that little bump, right above your nether lips?"
"Oh, that? That's my very special, very naughty spot. It's called a clitoris. Whenever I touch it... oh my goodness! It really makes me horny!"
"Then touch it! I want to see you horny."
Susan had never been so horny in her life, but even so, she did as she was told. She started alternating between rubbing her clit and caressing her wet pussy lips. Within seconds, she began writhing around as if she was about to climax. "Goodness gracious, that's GOOD! Mmmm! MMMM! Oh dear, I'm such a naughty mommy!"
She suddenly realized that she would be peaking soon. In an attempt to hold off, she tried not to touch her clit so much, instead focusing more on stroking her son's erection. But she loved doing that as well, so much so that it didn't do anything to cool her ardor.
A minute or two later she did climax, although it was only a medium-large one this time. She had to stop stroking and just grasp his hard-on as her body trembled all over. Since it was not a titanic orgasm, she was able to resist screaming like a stuck pig. Instead she just let out a series of erotic grunts and moans.
She thought, Mmmm! So intense! That must be God's way of rewarding me for helping Tiger with his special needs.
Since she'd never let go of his boner, she resumed stroking it.
He thought, Man, that's cool. I'm pretty sure Mom just had a big orgasm. Neat! I wanna give her lots of those! And now I can!
