nKatherine came home around that time, noticed the poolside gathering, and put on a bikini to join in the fun.

nAmy was sitting reading in her room and heard the sounds of laughing by the Plummer pool, which she could easily see from her window. (In fact, her window was the only one in the Pestridge house that looked onto the Plummer backyard.) She recalled what Katherine had told her the evening before, so she quickly came down and joined in as well. 𝗻𝗼𝐯𝗹．𝐨𝗿𝗴

nWithin minutes, Alan had gone from being alone to being surrounded by three voluptuous, scantily-clad women. (Suzanne remained in the Plummer house – for the moment.) He figured it was his lucky day, but what he didn’t fully realize was that Susan was put off by Amy’s presence. While she was practically family – she even called Susan “Aunt Susan” sometimes – Susan didn’t know how she fit in when it came to these sexual situations.

nHowever, Alan’s hopes for something erotic happening weren’t completely dashed.

nAmy lay down on her stomach on a towel, with her bikini top undone and lying underneath her. After a few minutes, she sat up and began chatting with Alan. Her bikini top remained on the towel, leaving her topless.

n“Hey!” cried Susan, when she noticed a few seconds later. “Amy, you’ve forgotten your bikini top. And in front of Tiger, no less! Please cover up immediately!”

nAmy stood up and reluctantly put her hands over her breasts. But she said, “No, Aunt Susan, I haven’t forgotten it. I’m sorry if I did something wrong, but I thought it was okay if we expose ourselves in front of him. I thought we were supposed to dress sexily and not wear underwear and stuff. Isn’t that what you all were doing the other night? Isn’t that a good thing?”

nSusan was flummoxed. “Well, yes, but to a certain degree only. No one asked you to run around topless!”

nAmy smiled. “No one has to ask me. I think it’s fun! Am I not allowed to go topless if I want to? Isn’t it a pretty common thing to do around private pools in back yards?”

nSusan was even more flustered trying to respond to that. “Uh, yeah, I guess it is. And since I’m not your mother, I guess I can’t tell you not to. But I do disapprove. It’s so improper.”

nAmy, completely ignoring Susan’s disapproval, said, “Yeay! Thanks a lot, Aunt Susan! You’re such a cool mom. It’s so much more fun over here than at MY house.” She stuck her tongue out at her house in playful defiance. “I’m going to jump in the pool.” She took her hands off her chest and dove into the water.

nSusan said to Katherine in a disapproving voice, “That Amy. She seems so free about taking her clothes off. Thank goodness, Angel, that you’d never ask me if you could go topless.”

nKatherine opened her mouth and then closed it in frustration. Inspired by Amy, she had been just about to ask that very thing, but Susan’s comment dashed that plan.

nSusan was still clueless about the extent of Katherine’s sexual feelings toward Alan. She would have flipped her lid if she’d known about Katherine’s pool escapade the day before. Susan’s sexual attitude was very confused and unstable at that point, which meant that she was confused and inconsistent in dealing with Katherine too.

nKatherine was still deciding what to do when Alan said, “Thanks, Mom, for being so cool about Amy and all. I think I’m going to jump in the pool too.” He dove in, angling to get closer to Amy’s generous orbs.

nKatherine didn’t want to be left out, so she dove in after them.

nSoon the three teenagers were splashing each other and having fun. They began playing water games that none of them had played for years. For instance, they played Marco Polo, where one person had to keep their eyes closed and try to find another person.

nOf course, the key fact was that Amy remained topless. As a result, Alan’s dick stayed very stiff in his bathing suit.

nSusan felt a child-like desire to join in. Deep down she felt like she was still a kid at heart. But she decided it would be unseemly for a parent to play such a game.

nNormally, she would have brought a book to read if she was tanning herself by the pool, but she’d come out carrying nothing but the cookies. So she closed her eyes and tried to clear her mind, since she was still practically trembling with excitement.

nHowever, she couldn’t stop thinking. This is a very distressing situation. Amy, topless! It’s not like Tiger needs the visual stimulation. His member is EXTREMELY aroused. One look at his bathing suit proves that! I sure hope Amy and Angel didn’t notice, but how could they not? I have half a mind to take MY top off too! Her tone was as if she was threatening a punishment, but she belatedly realized that would be no punishment at all.

nWait. Did I really just say that? Why should I take MY top off?! How would that help anything? Although… Suzanne says I need to do more to help him with his problem. What if he got out of the pool and we were all alone, and he just started taking care of his problem then and there, while staring at my bare breasts? That would be SO HOT! Although… that would be the sin of Onan. I should be the one to help him directly! YES! Mmmm! On my knees, my bare boobs bouncing, and my fingers pumping up and down his hot pole! That’s the kind of help I should give him! Oh God! Yes! Yes!

nShe was refraining from touching her own privates, but she realized her body was squirming around quite a lot in her lounge chair. She opened her eyes to check if anyone had noticed. To her relief, the three teens were busy having fun in the pool. She closed her eyes again and mentally reminded herself to act calm and cool. But such lusty fantasies continued to occupy her thoughts.

nAmy didn’t engage in any hanky-panky in their water games, but Katherine certainly did. With Susan not looking most of the time, she took every opportunity to touch Alan that she could get away with. This mostly happened when Amy had her eyes closed in their games, since games like Marco Polo involved closed eyes. Katherine would peek out when her eyes were supposed to be closed, and zoom in on Alan’s body, “accidentally” rubbing her body all over his. Several times she even grabbed his erection through his shorts.

nMore than once, she grabbed his erection through his suit and held onto it briefly as if she were trying to figure out what the big thing between his legs was. She gasped in horror, eyes wide open in shock. Then she “realized” that she was still holding it and acted even more surprised, until she finally let go of it as if it were a hot potato.

nAlan enjoyed this game a great deal, even if he couldn’t really figure his sister out. He was remarkably slow on the uptake due to his lack of prior sexual experience. Even what had happened with her by the pool the day before hadn’t fully clued him in to how much she lusted after him. At first he’d thought her grabbing really was accidental, since they were playing very physical games with a lot of touching and grabbing, but it happened so often that he’d eventually begun to wise up. However, he also was too shy to see what would happen if he reciprocated, especially since he never knew whether Susan or Amy might see what he was doing.

nHe really wanted to try something, but he kept chickening out. After a while he thought, This sucks. I need someone like Aunt Suzy to take the situation in hand, so to speak.

nKatherine was having a great time, but she was irked that he didn’t fondle her tits a single time, even though she rubbed them up against his chest repeatedly. She thought, Sheesh! How much more obvious do I have to get? Whatever hesitancy and guilt she’d had in the wake of exposing herself to him at the pool the day before was long gone, swept away in all the excitement of flirting and touching. She figured the cat was out of the bag about her attraction to him anyway.

nFinally the three of them grew tired and went back to lying in the sun. Alan thought that he’d get his chance to apply lotion, and suggested, “Does anyone need any more suntan lotion?”

nBut Amy happily said, “No thanks! I put some on earlier and it’s waterproof. Isn’t that cool?”

nAlan didn’t find it so cool. He was bummed. (He didn’t realize that Susan would have put a stop to him anyway, since she was concerned about him laying his hands on Amy while she remained topless.)

nKatherine had used the same lotion already as well, so even though she wanted Alan to put some on her, she figured she’d get called on it.

nBut she figured she could at least do her part in providing some more “visual stimulation.” So she decided to have her revenge at her mother’s no-topless rule by lying face down and undoing her bikini top, just as Amy had done earlier. But then she went one step further and “accidentally” undid her bikini bottoms as well, since they were the kind that could be untied on the side of the leg. She initially left them in place, but slowly let them slip open across her butt while she pretended to rest with her eyes closed.

nAlan certainly didn’t fail to notice what she was showing; he stared especially intently at her ass. Her body shone alluringly from all the suntan lotion and his erection showed no signs of subsiding.

nAmy noticed that Katherine’s bikini bottoms were coming off, but saw nothing wrong with that. In fact, after some minutes, she decided she would follow suit. She stood up and began taking her bikini bottoms off as well.

nThat finally forced Susan to say something. She sensed someone standing up and opened her eyes to see what was happening. When she saw Amy with her bikini bottoms down below her knees, she exclaimed, “Amy! For the love of God! What are you doing?! Stop that right now!”

nAmy had managed to completely remove the bikini bottoms while Susan was complaining. She stood there just holding them in her hand, while Alan eagerly drank up her nakedness. She was providing him with a side-profile view, so he couldn’t see her pussy, but the sight of her big bare ass was very nice compensation.

nShe stared at Susan with a clueless expression on her face. “What’s wrong?”

nSusan huffed, “What’s wrong?! You’re taking your bikini off, that’s what’s wrong! Put it back on, now!”

n“M’kay,” Amy finally said in a bummed voice. She bent over and began to stick her foot back through one leg-hole of her bikini bottoms.

nAmy seemed to be having a lot of trouble putting her clothes back on. That presented Alan with the sight of her naked butt wiggling just a few feet from where he was sitting. Since he was wearing sunglasses, he could stare to his heart’s content. He just assumed that no one was the wiser.

n“Sorry, Aunt Susan,” said Amy as she still struggled to get dressed with her bikini bottoms down around her ankles. “I was just thinking that Katherine had a good idea, and I wanted an all-over tan too.”

nAmy turned to face Susan as she pulled her bikini bottoms to her knees. That meant she was facing Alan too, since he was sitting on the lounge chair next to Susan’s. And that meant that he had a great view of Amy’s pussy from just a few feet away.

nSusan gasped. “Amy! Don’t let Alan see your you-know-what!”

nAmy stood all the way up while leaving her bikini bottoms around her knees. “No, my what?”

nSusan was franticly waving her hands. “You know, the private place between your legs!”

n“My asshole?” Amy remained frozen in place until Susan explained herself.

nSusan grew painfully embarrassed and found her nipples were rock hard again. “No, your other, uh, hole, er, down there.”

n“You mean my cunnie? My cunt?” Amy helpfully ran a hand up her thigh towards her pussy.

nSusan griped, “Amy! Such language!”

nAlan couldn’t believe how very aroused he was. Being unable to masturbate and relieve the built-up pressure was maddening. He could have readjusted his package so his erection wasn’t so obvious, but he was getting a secret thrill out of keeping it blatantly obvious.

nAmy still stood there, with her breasts and pussy on full display. “Well, what’s wrong with showing him that? After all, Katherine is too, pretty much.”

nSusan’s eyes had been closed for a while, since the others were resting and she was secretly reveling in her sexy incestuous fantasies. As a result, she hadn’t noticed how Katherine’s bikini bottoms had slid off until they covered little more than part of her ass crack. She cried in horror, “Angel, what are you doing?!”

n“What? What’s wrong?” Katherine asked in pretend cluelessness. “Did something happen?” She purposely sat up and turned around to look directly at her mother as she spoke. This left her bikini top on the ground, while her motion caused her bikini bottoms to fall all the way off as well.

n“Angel! You’re completely naked!” Susan nearly yelled, gesticulating wildly in agitation. “Put something on right away!” She reflexively put her hands over her own chest and looked over at Alan. She could read the excitement in his expression, not to mention see the size of the lewd bulge in his swimsuit. She chided him, “Tiger, don’t look at your sister like that!”

nBecause Alan was wearing sunglasses, Susan couldn’t actually tell where he was looking, but she could guess well enough. Besides, if he was looking at Amy with her bikini bottoms around her knees, that was just as bad.

nSusan found herself getting flushed and agitated as she stared at his bulge a few seconds too long. She just knew that he had to be looking directly at her from behind his shades. She was further embarrassed to realize that he’d obviously noticed her checking out his package.

nShe tried to backtrack. “Not that I would, uh, know, er, where you’re looking, Tiger. And of course I have no way of knowing that you’re erect, um, uh, I mean, aroused. That is to say, excited. It wasn’t like I was looking at… your… After all, I’m your mother!”

nSeeing that she was just digging a deeper hole for herself, she turned to Katherine and barked, “Angel, what’s gotten into you? Hurry up!”

nKatherine was still sitting up, tying one side of her bikini bottoms back together. That left her topless and mostly bottomless too, since the other side of the bikini bottoms hadn’t yet been re-tied. She was deliberately taking her time.

nSuddenly Amy walked into Susan’s view as she came over to help Katherine. “Need any help with that?” she asked sweetly. The only problem was, she was buck naked, having temporarily given up on putting on her own bikini. In fact, her bikini bottoms were no longer around her knees; they had been left behind on the ground.

nNow Susan was really at a loss. “Amy! No! Please! Go back to where you were and put your own bikini back on, thank you very much! NOW, please! Let Angel take care of herself, and quicker, please. For crying out loud, everybody needs to put some clothes on!”

nShe thought, This is ridiculous. Amy and Angel are incorrigible. Are they purposely wallowing in depravity, or just trying to test me, or what? I feel like I’m fighting a losing battle here. I might as well just take off my bikini as well. Hrmph! I’m so exposed as it is in this scandalous bikini, what would be the difference?

nHer pussy started to tingle as she warmed to the idea. What if I DO just strip? After all, Suzanne says I need to give Tiger more visual stimulation. And look: Amy and Angel are both fumbling around and taking forever getting their bikinis back on. I need to defend their virtue. If I were to unleash my big breasts, certainly my Tiger would look my way instead of back and forth at the other two like he was trying to watch a ping-pong match.

nHe’s obviously very hard. Very, very stiff. He needs to whip out his member and “jack off,” as Suzanne calls it. Maybe he’d get so inspired seeing me naked that he really WOULD whip it out and stroke it right here in front of me. Er, I mean us. God, that would be SO HOT! Uh, I mean, it would be very, uh, helpful with his, uh, medical treatment.

nNot only that, but Suzanne strongly made the point that it’s morally imperative that Tiger should never spill his seed on the ground. If I were to suggest that he blast his creamy load all over my face and chest, I could save him from that sin! In fact, that’s another excellent reason for me to take my top off, so he doesn’t stain my bikini with his nasty seed when he ejaculates all over me! Oh God! Such POTENT and FERTILE seed, coming from that BIG, THICK erection of his! Mommy’s just gonna DROWN in a cum bath of love!

nBut Susan’s fantasy of stripping was just that – a fantasy. She never seriously considered the idea. As she looked around and saw Amy and Katherine as they finally finished getting their bikinis back on, she slowly returned from her erotic daydream.
