You'll Live to Regret It. Pt.3 by Musclehead So last night, with Penny upstairs engaging in very loud and very rough sex with some unsuspecting guy, Mom got so turned on listening to her sexually aggressive daughter that she dragged her husband upstairs for some gratifying oral sex, her way. With her new-found fitness level, thanks to her daughter, she was now wearing the pants in this relationship. Her libido was also as high as it had ever been in her life, also thanks to her over the top daughter. And seeing all these dominating females in action got Shelley going for the second time that day as well. She wasn't physically stronger than Nick yet, but she sure was quickly becoming more aggressive when it came to sex, also thanks to her own new-found fitness level over the last several months. And an argument could be made that Penny had something to do with that as well, due to Nick's efforts to make himself fitter and stronger and Shelley joining him in those endeavors. Certainly on this night there was a direct line between Penny's sexual ravaging of that poor guy and how turned on Shelley was. So, it was morning. Shelley awoke feeling full of energy. Nick was still fast asleep on the living room floor. Shelly was sure that the awesome sex from the previous night had totally worn him out while energizing her. She also knew it had made her super hungry. In the kitchen, Mom was busy preparing some eggs, while drinking down a protein shake. She was dressed in workout clothes and she looked incredible for someone in her early fifties. "Good morning. Where's your husband?" "Oh, morning, Shelley. I wore him out last night. I always do. Thanks to Penny and my new fitness, he just can't keep up with me. It seems that the same is true for you and Nick. He looked pretty out of it when I went through a few minutes ago." "Well, he's very fit but I was so turned on last night listening to Penny and you upstairs having your way with your men that I think I did wear him out." "Are you stronger than my son?" "No. Pound for pound I am, but overall, he's stronger due to the size difference. Why. Are you stronger than your husband? He's quite a bit bigger than you." "But I'm stronger, period. And faster and way fitter. Would you like that for yourself, you know, with my son?" "Sure, what woman wouldn't? How did you do it? Nick said you used to be out of shape and overweight." "Well, Penny's been training me. And she gives me this supplement, Muscle Force, that makes my workouts super intense, and helps build muscle and strength quickly. You should see how strong Penny is. Well, I guess you heard it last night. I'm sure she fucked that guy to within an inch of his life." "Yeah. I saw him when she helped him down the steps and let him out. He looked like he had been in a fight with a wild animal." "He had." "But I saw Nick beat her in arm-wrestling." "Oh, child, I'm pretty sure that I could beat Nick in arm-wrestling. Penny must have been sandbagging him. She probably has something in mind to show him her power sometime in the future." "Where is Penny? I was sure she'd be up by now. With her energy level ... " "Oh, she's down in our home-made gym. She already ran about ten miles at about a six minute clip. And she looked fresh as a daisy, except for the sweat, when she got back. She has twice, no, three times the energy of the average person." "But she doesn't seem all hyper or anything." "No, it's under control most of the time, and then, when she wants to use it, her energy, that is, it's super concentrated, like an explosion. That's what that poor guy found out last night. He thought he was gonna have some great sex with a hot girl. And I'm sure it was the most incredible sexual experience of his life. Little did he know that with a girl like Penny, great sex could also be life threatening." Mom looked over at Shelley who had a far-away look in her eye. "She gets you going too, huh?" "Yeah, I mean not turned on or anything", she lied, "I just wanna be like her." "You can start today. Go get dressed. We can lock the door from the inside of our little gym so we can't be interrupted. Nick won't know what you're up to." Shelley scurried off to get dressed. Nick was still out of it when she went by, thinking to herself that it would take some work but she was convinced she could overtake him in the strength department. She sure had him beat when it came to endurance. When she got back to the kitchen, Mom handed her a carafe with a protein smoothie in it. "Here, drink this." Shelley wolfed down the drink, which Mom had put some Muscle Force in, and that feeling in Shelley's scalp started very quickly since she drank it on an empty stomach. Soon, it was spreading to her whole body as they entered the gym. As soon as they hit the gym, Shelley, with a quiver in her voice, asked if there was a toilet close by. Mom pointed to a door in the corner. As soon as she got into the bathroom, she shoved her finger into her gymshorts and brought herself off. The combination of the Muscle Force and what she had seen when she entered the gym had cause her to feel the need for immediate sexual gratification. When they had entered the gym, there was Penny, with her back to them, doing wide grip pullups with a forty-five pound weight hanging from her waist. She was fully covered, a long sleeved shirt and baggy shorts so Shelley couldn't see her muscles straining, but she was turned on by the image anyway. Shelley herself knew that her own accomplishment of doing eight pull-ups, regular ones, was pretty damn good. Wide grips were much harder, and with extra weight, for twenty reps, phenomenal. Gathering herself, she went back into the gym. Penny came up to her, taking both her hands and looking her in the eye. "No more masturbating when you've taken some Muscle Force." "How'd you know?" Shelley didn't want Penny to know how much she turned her on. It was bad enough that she let it slip to Mom even as she denied it. "Because that's what I did the first time I took it." "Me too," chimed in Mom. "This stuff is for working out and getting stronger than most men. Use you boyfriend's dick or face when you want to get off. Nick does go south with the mouth, doesn't he?" "Yes. He's willing and devoted." "Well, let me tell you something. That's all well and good, but you're gonna find out after a couple of months of working out with the help of Muscle Force, that when you make him do it whether he wants to or not, it will take you over the top like never before. Right, Mom?" "Yes, indeed." "Pete's coming over to swim this afternoon. Maybe I'll give you a demonstration of what I mean." And so they worked out. Shelley was indeed astonished by Penny's strength. And Mom was pretty amazing for her age. Shelley too felt like she was somewhat stronger by the end of that first workout. At the very least, it was the best work-out of her life. Later that afternoon, Shelley and Nick watched as Penny dismantled Pete quite easily. Nick had been told by Penny the previous summer that she could beat Pete, so he wasn't surprised by the outcome, and while he was cursing himself under his breathe for being turned on watching his sister in action, it really didn't dawn on him how little effort Penny was putting forth while overwhelming Pete. As for Shelley, she was totally aroused watching this demonstration of female superiority, but she continued to hide it well. However, she could see that Pete wasn't doing a very good job of hiding the stiff wood in his trunks as Penny rode his face after her victory, but how could he? She had him so wrapped up, the only thing he could move was his tongue. Seeing that Pete was getting off as much as Penny, Shelley turned to Nick. "Would it turn you on if I could manhandle you the way Penny's doing with Pete?" As Nick looked away in embarrassment, Shelley continued. "You don't have to answer, I can see it written all over your face." Shelley turned back to the action just as Penny squealed with delight and Pete erupted simultaneously. She smiled to herself, knowing that the day would indeed come when she would take Nick like this. Several days later, they were sitting in the kitchen and Penny was instructing Shelley about eating lots of protein and avoiding too much carbs. "By the way Shelley, there's this guy coming over this afternoon. He thinks he's all that. I haven't met him yet. He hit on Mom at the store the other day." Shelley looked over at Mom with a surprised look on her face. "Yeah, Shelley, with my new-found in shape body, I get hit on a lot, even by young men. This guy is, like a sophomore in college or something. He was bragging about how he was state wrestling champ and track star and all. I got sick of it after a while, so I invited him over for a swim. I told him that I was happily married, but I had a very athletic daughter he might like to meet. Penny chimed in. "A sort of setup, you might say. I've told Mom to take Nick out shopping or something. I just don't want him around this afternoon. You'll see why later. Do you wanna see me put this guy in his place?" "Sounds like fun." "Wear your tiniest bikini. I'm gonna be doing that. I wanna get this guy as horny as possible." "I don't hold a candle to you, Penny." "Don't sell yourself short, Shelley. You have a very nice, fit body." "Thanks, but you're world class." "Thanks. That's nice of you to say. We'll see what this guy thinks. Hank, is that his name, Mom?" Mom nodded in the affirmative. "I wanna be there too. I'll make Dad take Nick somewhere. He does everything I tell him. He knows I'll cut him off if he doesn't listen to me. I make him eat me most of the time, but he's also getting the best sex of his life. Besides, like I said before. I'm stronger than him now, and the strong rule, as it should be." Later that day, Shelley was sunning herself out by the pool. Her body had steadily improved over the last several months since she had started working out, but in the last week since she started working out with Penny and her Mom, and using the Muscle Force supplements, she had seen a quick jump in her strength levels and her body had responded quickly as well. She certainly could enter an amateur level fitness contest, her body looked that good. Like Penny had suggested, she wore her skimpiest bathing suit and any guy who wouldn't find her to have entered the realm of "hot" at this point, must be gay. Nick had certainly noticed the visual improvements, but she hadn't let on yet about the strength increases. When the guy who had hit on Mom at the store arrived, she was still the only one out by the pool. "Hey, I'm Alex. Whoa. Bitchin' Bod. Are you the daughter?" "No, I'm the son's girlfriend." "Well, is the son around?" "No." "Well then, I don't mind telling you that you look good enough that I just might fuck you if the daughter doesn't measure up to my standards." "I wouldn't be unfaithful to him though." "Is he as well built as me? Baby, I'll rock your world." "Wow. You're so smooth." Mom had walked up just as Alex was showing how crude and ignorant he was. He turned around to see this phenomenal fifty something with as little on as Shelley, and quite frankly looking just as good and quite frankly showing more muscle. "Mrs. Adams, you look incredible. What about you? You wanna fuck? That's why I'm here isn't it?" "You're here to meet my daughter." "I hope she's as hot as her mother. I never thought I'd say this, but your muscles make you sexy as hell. I'll bet you're a great fuck. Does your daughter have muscles like you?" "Why don't you ask her yourself? Here she comes." Penny came down to the pool wearing a long robe. Alex could tell even with the robe on that she had a great body. And with the red hair and piercing green eyes, Penny would look sexy in a burlap sack. Ever the asshole, Alex turned to her. "Hey Babe. I hope you're as hot as your Mom here and your brother's girlfriend. Neither of them want to fuck me even though it would be awesome for them. I can't very well tell what you look like with that robe on." She didn't say a word, she just dropped the robe at her feet. Shelley let out a loud gasp. Yes, she had seen her in her sports bra and shorts, and with the thong and wife-beater. And with that one piece bathing suit she had worn to the pool several times anyone could still tell that Penny had a great body. But nothing had prepared Shelley for what stood before her at this moment. Penny's suit covered her nipples, and her pussy and that was about it. Every detail of her perfect powerful body was on display. Alex certainly new that it was by far the most amazing body he had ever seen, and he just stood there with his mouth open as Penny turned and trotted towards the pool, gracefully diving into the water. A few seconds later she swam to the side and putting her hands on the edge, launched herself out using arm strength only. Her nipples were so erect from the cold water that they could cut glass. "Oh baby, I wanna fuck you sooo bad." "Listen cowboy, I have a world class body and I guarantee I'm a world class fuck. You have to prove yourself worthy of me." "What did you have in mind?" "A four part challenge. If you pass all four tests, you can fuck me, and baby, you do not want to miss out on that opportunity." "You're on. What's first?" "Arm wrestle with Shelley." "You're kidding, right. I was all state in wrestling and track in high school." "Yeah so my Mom said." "Penny, I can't beat him." "Just give it a try, Shelley." They sat down at the picnic table and locked up. Mom said go and, ... "Ungh, you are one strong bitch." Alex had to work hard, but prevailed. "Not real impressive, cowboy. Great job, Shelley." "I won, didn't I? She's real strong for a girl, though. What's next? Beat your Mom in arm-wrestling?" 'No. You have to do more pushups than her. Both of you get down on the deck. I'll count Mom's and Shelley will count yours." And so they both went at the same time. Mom did an astounding seventy-five and Alex had only done fifty-eight, but Penny had whispered something to Shelley during the contest, and Mom was already in on the setup. "Alex wins, but just barely. This fifty-two year old woman did fifty-five." "What's next?" "You arm-wrestle me." "But I just did all those pushups. It's not fair." "What a fucking baby you are. But I am just a girl and you're a big all state wrestler. Actually, we're just about the same size. I didn't mean big that way anyway. Whatever, I guess you don't want to fuck me." "I do, I just wanted a level playing field. Why don't you let me rest a minute." "Fine. Tell you what. I'll do some pushups too." She dropped down and did a hundred pushups, military pushups. Bouncing to her feet, she went over to the table. "Come on pussy. I don't need any rest. Which is your strong arm?" "My right. You?" "My left. Let's go right." They locked up and when Shelley said go, Penny put him down so fast, he didn't even know it was over. "Damn. You must be a professional. I hear it's a lot of technique, getting a jump and all. It doesn't prove you're stronger." "But when Shelley put up a good fight you said she was strong. Sorry, no fucking today." "Oh, come one. You hot babes, three of you with almost nothing on have made me real horny. Give me one more chance. What was the fourth one gonna be, the fourth contest?" "Well I was gonna let you choose. Because I didn't expect you to get this far. But I'm kind horny as well. Okay, one more chance. You choose." "Okay. I choose wrestling. I know I'll win there and I'll prove to you at the same time that I'm stronger than you. Plus I'll get to put my hands all over that luscious body of yours and you'll get to fondle my muscles as well." "Okay. Over there?" She pointed to a spot where they actually had mats set up. It was where she had wrestled Pete the week before. And there were some mats against the fence as well. Shelley was thinking to herself that this guy must be really stupid not to wonder why there were mats in a back yard. Much to Shelley's dismay, after about ten minutes, Alex seemed to be well in control. He had Penny lying on the mat on her stomach and he had an un-breakable full nelson on her. He was driving his crotch into her round hard glutes and pushing her head down hard. And then, Penny slowly maneuvered her hands behind his head even as she remained in that tight full nelson. She intertwined her legs with his and suddenly he was writhing in pain as she was squeezing his face into the back of one of her shoulders while clenching her legs in a reverse grapevine. She relentlessly poured on the pressure for close to a minute. He had all the advantages, position, leverage, etc., but she was simply put, much much stronger than him. Eventually she felt his legs go limp but she still kept squeezing. When she felt his arms loosen, she somehow bent her legs and got the bottoms of her feet under his lower thighs then suddenly pushing with great force as she held onto the back of his head, flipping his body over hers where he landed with a thud on his back. In a split second, she was behind him, wrapping those powerful legs around his torso, but capturing his limp arms as well. Penny reached forward with both arms and grabbed his ankles, capturing his head behind her left arm, his throat wedged into her armpit as she sat back up. Alex couldn't move anything. Then, to make matters worse, she leaned back and spread his legs as far as her arms could reach and once again poured on the pressure. She actually rolled far enough onto her back that she was holding him up off the mat and above her. This was not the Penny who playfully wrestled her loving boyfriend the week before. This powerful young woman was intent on destroying this asshole. Shelley was all but swooning watching this hot warrior princess in action, while not doing nearly as good a job at this point in hiding her arousal. Mom didn't dive a shit, sticking a finger in deep as she watched her amazing daughter. It was obvious with his legs spread that Alex had quite the erection even as Penny was putting him into a world of hurt. About a minute later, she released her hold and his lifeless body fell to the mat. But Penny wasn't done yet. She grabbed him under and armpit and in one fluid lotion, wrenched him up off the mat and whipped him into the matted fence, following up by leaping at him, pulling her arms and legs back and leading with her hard torso, slamming him between her perfect body and the fence. He was already out on his feet, but Penny was so quick that before he could sink to the ground, she leaned to the right, grabbed him so his body was perpendicular to hers, across her chest and then she spun, slamming him onto his back with such ferocity it was a miracle that she didn't break his entire ribcage. She bounced to her feet and walked around him, breathing deeply, more from arousal than having expended a whole lot of energy destroying this inferior male. There was just something so hot about this beautiful athlete looking so fresh and this man lying on the ground who was so utterly destroyed that he couldn't even lift his head off the ground. She turned to Shelley and whispered, "Don't just win,dominate." Penny plopped down onto his head, facing his feet and pulling that tiny patch to the side and shoving her sweet pussy onto his mouth. In spite of being mostly unconscious, his tongue started to lick. She reached down and tore his shorts off. He was fully erect, maybe as hard as he had been in his life. Shelley was so taken by this superior female that she completely lost her focus, her eyes rolling back in her head as she had the most sexual experience of her life, missing Alex's eruption as Penny mercilessly ground herself on his face. When Shelley wound down from her sexual high and opened her eyes, Penny was gone and Mom was impaled on Alex's shaft pinning his arms above his head and smothering him with her breasts. She looked over at Shelley through glazed eyes. "He may be a total asshole, but that is one big dick. He was still hard as a rock even though she knocked him out and probably banged up every square inch of his body." As this older woman went back to sexually dominating this younger man, Shelley knew that it was to be her destiny to be able to dominate Nick like this, and soon.
