Susan felt guilty for her hypocrisy in chastising the girls for getting naked when that's what she secretly wanted to do herself.
Once things settled down and Amy and Katherine had their bikinis back on and were lying on their own lounge chairs, Katherine said, "Sorry, Mom. I guess my bottoms must have gotten untied somehow. I didn't even realize."
Susan was so trusting that she didn't suspect deliberate shenanigans. "I'm sorry too. I guess I over-reacted. I thought you'd done that on purpose. I even forgot they made bikinis that untie like that. Let me guess - Suzanne just bought that for you."
Katherine grinned and nodded.
Susan sighed. "That woman. What is she doing to this house? Why do they make them like that, anyway?"
Katherine explained, "It's helpful if you want to eliminate tan lines. And I've got some serious tan lines I'm trying to get rid of. In fact, would it be okay if I untie them on purpose? I'll be super careful to make sure all my important spots stay covered."
Susan sighed again. "I suppose it's okay, as long as you stay extremely careful. I know how you've been trying to get rid of your tan lines lately. But be careful when you're sitting up like that, or you'll give Tiger a free show." Normally, she wouldn't have given such approval, but on some unconscious level she was hoping that the generally increasing levels of nudity would let her expose more of herself as well.
"I will," Katherine said, immediately untying her bikini bottoms again. "But... just out of curiosity, would a 'free show' be so bad? I thought we were supposed to get sexier, as you put it. That's why I was wearing a bikini in the first place. Isn't that why you're wearing one too?"
Still more than a little aroused, Susan said, "Okay, you got me. I suppose I am wearing a bikini in the hopes that Tiger will look at my nearly naked body and feel inspired to shoot a big load." She glanced over at her son, and suddenly felt extremely embarrassed that he'd just heard that. "Um, wait! I didn't mean it like that! What I meant to say is-"
Katherine interrupted, "It's okay, Mom. I know what you mean. And he thanks you for being such a cool and helpful mom, don't you, Big Brother?"
He was startled out of his babe-watching reverie from behind his sunglasses. "Me? Oh yeah, totally. Thanks. All of you."
Amy replied, "No prob, Bo. It's totally fun! I love to get naked. Aunt Susan, would you mind if I take my top off again? I promise I'll keep the bottoms on this time."
Susan sighed. "Very well. Since I'm not your mother, I guess I can't stop you."
"Woo-hoo!" Amy whipped her top off immediately.
Susan continued, "But Angel, you ARE my daughter. A little bit of visual stimulation is all well and good, but I worry about these bikinis. You know how I've complained about bikinis in the past. I don't know why I listened to Suzanne. She just bought this one for me and practically forced me to wear it. Next time I'll wear the one she bought me last week. That one is a little more respectable, at least."
Katherine giggled. "No, Mom, I think the one you've got on is great. It's the kind most people wear. I think you look super sexy. I didn't know I had a total fox for a mom."
Susan lapped up the compliment. She egged her on with the reply, "No, you're just saying that."
"No, really. Don't you agree, Brother? What's especially sexy are your nipples. I've never seen nipples so pokey. They're just about to poke right through your top. You must be thinking about something really sexy!" She giggled some more.
Susan was aghast again and blushed profusely, since the only logical candidate for her arousal had to be the ridiculously obvious bulge in her son's bathing suit. She stammered, "No, I wasn't... It's just... Tiger, don't... It's just that, uh, Son, don't look at your mother's nipples like that!"
All this talk had of course turned Alan's attention to his mother's breasts, and especially her highly visible nipples. He'd been spending much of his time at the pool staring at them and at the rest of her body from behind his dark sunglasses, but he was happy for the reminder to continue to enjoy the sight of her immense breasts.
Susan continued, while flustered and wiggling around, "Oh my goodness! I'm so embarrassed. I wasn't thinking about anything in particular! The fact that Tiger is here with his muscular chest and big bulge has nothing to do with it! Sometimes nipples just get hard for no reason, just like the private parts of men do."
Susan realized she'd said "big bulge" and blushed even more with shame. She finally put one arm over her big tits and hid her blushing red face with her other hand.
But that only aroused Alan even further, since her breasts were so big that her arm couldn't hope to cover them, and the way her tit-flesh bulged in response to the pressure was extremely titillating in its own right. On top of that, when she put her hand over her face it meant that he could stare even more blatantly at her body, now without worrying about whether she could tell where he was looking.
Susan thought, Dear Lord, please help me! I'm sticking my foot in my mouth and embarrassing myself again and again. Why do I have such wicked, sinful thoughts about my son and his phallic bulge?! Whatever happened to Suzanne?! I wish she'd come and rescue me!
In fact, Suzanne was watching from the house. She was staying away for the moment because she figured that the more people were there, the more inhibited Susan would act. She couldn't hear what was being said, but she could see enough to tell that her plan was progressing nicely. She was displeased to see Amy getting naked, but she figured it was best to let that slide for the moment, so as to not disrupt the progress being made with Susan.
Alan was definitely on the verge of cumming again, just from all the visual stimulation around him. He was grateful for Suzanne's recent help in learning to clench his PC muscle. He frantically strained with all his might to prevent himself from ejaculating into his swimsuit. He lay there as still as a statue, for fear that any friction from his swimsuit on his cockhead would push him over the edge. His heart was still thumping like mad, so much that he was even sweating from the strain.
Amy suggested, "Aunt Susan, why don't you take your top off? I'd like to see those super-pokey nipples. We could all get topless. Wouldn't that be fun? Nudity is totally neat-o! And it would be like, visual stimulation for Alan to get better. Right? This visual stimulation stuff you just talked about is the same as the effort to sex things up, isn't it?"
Susan turned yet a darker shade of red. "It is, but Amy, we'd better not. I think he has seen plenty enough of all of us already. Too much, in fact! Don't you agree, Tiger?"
"No, Mom. I'd love to see you topless. I have to agree with Sis. You ARE a total fox. A stone cold fox, like I said before. You should be proud of your impressive chest and well-built body. I don't know why you've been hiding it for so many years."
She thought to herself, I know it's weird, but can't I feel pride if my son gives me a compliment? I'm a "total stone cold fox," which sounds pretty darn good, even though I still don't know what that really means. Hee-hee! Now, if only these damned nipples would go down already!
She took another furtive glance at the bulge in her son's shorts, and then forced herself to turn away. Maybe I SHOULD go topless! Suzanne says I need to step up my efforts to help him with his spermy problem. Tiger's penis has been so very long and stiff for such a long time... The poor boy must be suffering! It's time for him to cum! And, if he were to cum on my face, or my chest, then he wouldn't be spilling his seed on the ground like Onan did! Mmmm, yes! Tiger, cum on me! Cum on Mommy!
She suddenly caught herself, and realized how much her boobs were heaving up and down in time to her heavy breathing. She folded her arms under her rack in an attempt to lessen her bouncing. Goodness gracious, how I'd love to do it. As it is, my bikini top hardly covers much anyway. But someone here needs to be the responsible one. I need to set a good example for Angel and Amy. It's Sunday afternoon and I'm completely forgetting the teachings of Jesus. Didn't He say something against nudity? He must have. Didn't He?
So she replied, "No offense, Amy, but proper ladies don't go topless. It is VERY improper. I say 'No,' and that's that. I'm sure that Tiger has had more than enough stimulation for at least a couple of nice, long ejacu-"
She cut herself off. "Um... What I mean to say is, he should be able to reach his target today just fine, especially given the way you two were gallivanting around without your bikinis. Things are getting a little out of hand here, and everyone should just relax."
She closed her eyes and tried to let her mind go blank again, but found that impossible to do. But she was determined to at least pretend that she was resting.
She sorely wished she'd worn her prescription sunglasses instead of her usual glasses, so she could stare at Alan's body from behind the dark lenses. Her nipples hadn't gone down; she could even feel them throbbing. She repeated his words: "stone cold fox," "impressive chest," "well-built body." Oh, my son, I know such superficial features don't really matter in the eyes of the Lord, but your compliments make me so happy!
A few minutes later, things calmed down just enough for Alan not to worry about spontaneously cumming into his swimsuit at any moment. But his urge to cum was as great as ever, so he politely excused himself and hurried up to his bedroom. He was so inspired by what he'd seen and heard that he came twice in quick succession.
