We quietly ate for a bit and she grinned up at me, blushing a little. I leaned across the table and whispered, “I can’t wait to play with my pussy some more later.”

She giggled and sipped her coffee.

We went back to the house and some people had already started drinking. We’d been gone awhile, so it was almost noon. Chris saw us come into the TV room, outside the massive kitchen. “Hey Mads, you guys were gone a long time.”

“Yeah, we were hungry after our run, so I took Sam to breakfast at the cafe.”

“Nice, that place is good." He looked at her with a funny expression, "Mads, your knees are so dirty.”

She looked down at her mud covered knees and awkwardly said, “Yeah, it rained on us. It was really muddy out. I fell once.”

Chris laughed, “You should see yourself. It looks bad. Looks like you were on your knees, know what I’m saying?”

Madison laughed too long and hard at that, “Yeah, I know, right.” Madison went into the kitchen and grabbed a Gatorade from the fridge.

“Hey, can you throw me one of those, Stinky?” She gave me an exaggerated angry face.

Chris said, “Stinky? You call her Stinky?” He was laughing.

Madison threw me a Gatorade aggressively, and I joked, “Yeah dude, she was stinking up your car on the drive home with those pits.”

She turned red and defensively said, “It was Sweaty Sam over here, stinking up your car.”

Chris said, “Sure it was Stinky.”

Madison got serious and said, “That’s Sam’s nickname for me, not yours. You call me Mads.”

Chris shrugged and went back to his video game, “Sorry Mads.” I could tell from his expression he did not love the fact that I had a nickname for her.

Matt said, “Dude, both of you are filthy and you’re tracking mud in the house. Go fucking rinse off outside.”

Madison and I went out onto the pool deck. We sat in pool chairs and took off our shoes and socks. She held up one of her feet near my face, as I bent down to take off my shoes. Her foot was beautiful and I grabbed it and sniffed, “Whoa, that is stinky.”

“It’s my foot.”

“It still turns me on.”

“You have problems.”

She looked in the sliding glass door to confirm Chris was busy with video games. Then we both got in the outdoor shower together and locked the door. We stood in the warm water hugging and kissing, really making out. We were fully clothed in our running clothes, but rinsing off the mud. I slid my hand into the back of her running shorts to feel her ass cheeks. We stripped off our clothes and actually soaped ourselves up, but we were quick about it. I was starting to get a little hard and she stroked my soapy cock a little in the shower. We cut ourselves off before it escalate farther than that and we put our clothes back on. When we left the outdoor shower stall, it was pouring down rain again.

Madison looked hot with her hair all wet and just in her sports bra and tiny shorts. She grinned at me and then ran and jumped in the pool. I stripped off my shirt and jumped in behind her, almost landing on her in a cannonball. We rough housed out in the pool, wrestling and splashing each other. I felt her hand go into my shorts to grab my dick quickly.

I heard the sliding door open and Heather and Kristin came out into the heavy rain. They were laughing and Heather said, “Nice day for a swim.” Kristin was pretty hot. She was almost as tall as Madison, but had a more thin,lithe frame. Madison was more athletic; whereas, Kristin was just thin with long, delicate legs. Kristin had smaller tits, too and a more angular face. She had sparkly blue eyes and dirty blonde hair.

Madison yelled, “Get in.”

The girls looked at each other, shrugged and stripped down to their bras and panties, then leapt in the pool. We all played out in the rain, as some guys, including Chris were inside drinking and playing video games. Madison and Heather chased me down and stole my swimsuit, so I was naked out there. I didn't really fight them. I got up on the diving board and wagged my dick around before jumping in. They were laughing and then Chris and Matt came out.

Heather said to Matt, "Well, that makes like the one hundredth time, I've seen Sam naked."

He said to me, "Dude, it's barely even noon and you're out here naked?"

"The ladies stole my swimsuit."

Madison was giggling, "And then we lost it."

I climbed out of the pool and walked over to the outdoor bar to grab a beer out of the refrigerator. Matt and Chris groaned and looked away, as I casually walked across the pool deck naked. "Who wants a beer?"

Madison said, "Me please."

The other girls said, "Yes, please."

Matt said, "Dude, I'll get my own. I don't want some naked dude handing me a beer."

I shrugged and grabbed beers for the girls and they giggled, as I approached the side of the pool to hand them the beers. Heather and the other girl were blushing and giggling, as I squatted down right near them to hand them their beers. Madison was giving me a more lusty look. Matt and Chris were trying to avoid looking at this whole scene. Chris said, "Let us know when he is in the water for god's sake."

After handing Heather and Kristin their beers, I was squatting right near where Madison was leaning on the pool edge. I was holding her beer, where it would cover my crotch a bit, as I squatted there. Madison grinned at me and reached for the beer. She pulled it away, exposing my whole dick. No one else saw, the she ran her fingers down my dick in the process. I was not fully soft or hard. I was kind of swollen from the excitement of being naked in front of them. Since, I'd fucked Madison a bunch the night before and that morning, I was not quickly getting fully hard from this.

I sat on the pool edge, kind of between Madison and the other two girls, casually drinking my beer, naked in the light rain. I put my dick over top of my wrist on one hand and looked at it like it was a wristwatch, "Looks like it's beer o'clock." The girls were blushing and giggling.

Heather said, "You're such a freak."

Kristin said, "Does he always do this?"

Heather said, "I've seen the wristwatch thing before." The girls all burst out giggling.

We heard the front doorbell ring through a speaker. Matt said, "I think that's Sarah getting here. Sam, I dare you to go answer the door like that." He was giggling hysterically. Heather and Kristin laughed, "do it." Madison looked away from me and had sort of a jealous look on her face.

I had to go answer the door. First of all, I am an exhibitionist. Second of all, it was a dare and a naked dare is the most tempting dare of all. I casually got out of the pool and walked into the house. There were guys and girls in the living room. There were groans from all of the dudes, "Put some fucking pants on..." and the girls were all giggling. I strolled down the hall to the front door and opened it. It was Sarah. I saw her eyes drift down my body to my swollen dick. She giggled, "Um...nice to see you again."

"A bunch of us are out by the pool."

She grabbed my arm and I escorted her, naked, out to the pool area. Madison had a pensive look on her face. Sarah said to me, "Should I just put my stuff in your room?" and giggled.

Madison way too quickly said, "No, we already picked out a room for you." She sank just her mouth under the water to shut herself up and looked embarrassed.

Sarah looked at me, "Well, I'll just put my stuff in that other room for now, but who knows," and she looked down at my dick again.

I downed my beer and then cannonballed Madison, as she stood in the pool. There was some kind of sporting event on and there were cheers from the living room. Matt and Chris went to go see what happened on the TV. Madison and I migrated away from the others in the pool. Sarah stripped to her underwear, grabbed a drink and got in the pool. I grinned at Madison and she gave me an exaggerated angry face and splashed me.

I whispered, "What's wrong, Stinky?"

"You're just parading around naked in front of all of these girls."

"You're jealous?"

"Yes, a little."

"I just like being naked."

"Me too."

"Then, get naked."

Madison giggled, looked around, shrugged and slipped off her sports bra and running shorts. The other girls saw that and stripped naked as well, so I was naked in the pool, in the rain, with four naked girls and it was only about noon. The other idiots, I mean guys, were watching sports instead. Poor choices.

Kristin got out of the pool and I couldn’t help but admire her ass, as she walked toward the outdoor bar. She was standing under the roof of the bar and looking to see what was there. “Does anyone want a drink?”

Sarah yelled, “Let’s do blowjob shots.”

The other girls were giggling and said yes. I yelled, “I’d love a blowjob Kristin.”

Kristin gave me a sexy look, “I think I could arrange that.”

Madison gave me a jealous/angry look and splashed me. I went over and grabbed her from behind, dunking her. My dick grazed her bare ass cheeks. Her boyfriend was just inside, watching a game and not noticing that I was wrestling around naked with his gf.

Kristin carried two disposable solo shot glasses over to Heather and Sarah. I guess I was admiring Kristins naked body and Madison said, “She’s got a nice body, huh?”

I turned red, “I mean, Madison, you’re hotter than her…”

Madison grinned, “It’s okay, if you think she’s hot. I think the female form is beautiful.” She turned a little red and I felt like she was eyeing Kristin in the same way as me almost. Madison whispered, “She has perky tits.”

“Yes she does.”

Kristin came over to us and handed Madison a shot. Then she went to hand me one. She pulled it away, as I reached for it. “You have to perform for yours…”

“What?”

“Get up on the diving board and wag your dick around like you did.” She burst out giggling. The other girls cheered, except Madison who looked slightly annoyed. I slipped out of the pool and got on the diving board while they whistled at me. Now I was having trouble not being hard with this kind of attention. It was getting slightly hard. I got up there and bounced it around and did some helicopter dick. Then I jumped in a little red faced and swam over to Kristin, who was standing in the water at the pool edge.

Kristin had one disposable shot in her hand for herself and one in her other hand for me. She held it so that I had to get really close to her to get mine. She handed it to me and said, “Let’s do a blowjob…” and gave me a sexy look. We both did our shots at the same time and while I did mine I felt her free hand grab my dick. I almost spit out my shot, as she just grabbed it and pulled on it a little. Now I was fully hard. She let got of it and giggled, giving me a look. Madison was near enough, that I think she knew Kristin had just grabbed my dick.

Madison grabbed her from behind and picked her up in a bear hug from behind, dunking her aggressively. Madison was half joking and half pissed off that she had grabbed my dick. She couldn’t exactly act jealous, so she just played it off like she was play fighting. I looked at Madison and laughed a little. She smirked at me, as she released Kristin.

“Madison?!” She splashed at Madison, while slicking back her hair.

Madison shrugged and went over to give her a real hug, “I’m sorry friend. I was just playing.”

Kristin looked a little stunned to be getting a naked hug from Madison. If I hadn’t already been hard, I would have been hard now. Madison moved away again, and I could see they were both blushing a little and eyeing each other.

The girls were chilly and they all moved into the hot tub. I was still in the pool and completely erect. They yelled for me to join them. “Bring us beers, Sam and come join us.”

I was completely red faced, as I slipped out of the pool trying to hide my boner and running to the beer fridge. I carried the beers over and handed them out. They saw my boner and there were squeals and giggles. I climbed into the hot tub, between Madison and Kristin. We sat there drinking beers. I suddenly felt a hand on my dick and based on the angle, it had to be Kristin. She grinned at me. She was slowly giving me a handjob. Then I felt another hand. It was Madison. They must have felt each others hands because both hands suddenly disappeared and they gave each other a look. Kristin was giving Madison more of a shocked/disapproving look.

Chris and Matt came out, as it stopped raining. Matt said, “We’re going into town to eat and to pick up a couple of kegs.”

Chris carried a towel over to Madison. He said, “Can I talk to you a second, Mads?” He looked irritated. He tried to carefully obscure her naked body, with the towel as she climbed out. They walked a little away and seemed to be having an argument. I could hear a little and read their lips some to make out what they were saying.

“It’s not cool, you’re just hanging out naked with Sam.”

She defensively said, “It’s not just Sam, we’re all skinny dipping.”

“Yeah, but it’s like broad daylight and you guys are naked. He’s like fucking swinging his dick around.”

“We skinny dip all the time. You could have joined us.”

He looked over my way nervously, “I didn’t feel like it. It’s more of a night time thing.” I’m guessing he didn’t want to be naked in the light of day, a little self conscious.

Madison kissed him with a smile, “I like that you’re jealous, but I think Kristin is gonna fuck him.”

Chris broke out in a big grin, looking over at Kristin and me. She had sidled up to me and I could feel her bare hip on mine. Chris said, “I think he fucked her last night. I heard them,” and he broke into giggles. They were being louder than they realized. Madison involuntarily laughed that Chris heard us fucking the night before and thought it was Kristin.

Kristin probably heard all of this too and looked over at me confused. I shrugged.

Heather got out of the water, “I want to come with you guys. Maybe pick up some food to grill while we are in town. Can you come help out, Sarah?”

“Yeah, I’m pruning up.”

Chris said, "You want to come into town, Madison?"

"No thanks, I already ate and I think I might nap and take a shower."

"Okay, see you later." He kissed her goodbye.

And just like that, Madison, Kristin and I were the only ones at the house. When Chris was out of sight, Madison dropped her towel dramatically and climbed back into the hot tub. It was awkwardly quiet a minute, then Kristin gave Madison an accusatory look and said, “I felt your hand on Sam’s dick.”

Madison got a sexy grin, and moved through the water, to straddle Kristin’s lap, kissing her on the lips. She pulled back and Kristin looked stunned speechless. “What are you going to tell on me?” She started kissing Kristin some more. Kristin giggled and got into it. I saw their hands roam around some.

They saw me with my mouth open, staring. They both giggled. Madison said, “You’re still a good kisser, Kristin.” They both laughed and kissed a little.

I said, “You two…have…before?”

Kristin said, “We’ve made out before.”

“Does Chris know?”

They both laughed, “Oh, hell no. No one knows.”

I stammered, “So, have you guys?”

They both blushed. Madison said, “No, just some kissing. It was like this. We were the last two up one night and naked in the pool. We made out. Nothing more.”

They kissed some more and I could see that Madison was moving herself on Kristin a little. Kristin stopped the kissing abruptly and said to me, “Wait a second…who did Chris hear you fucking last night?”

Madison blushed and got a guilty look, she kissed Kristin, pulling on her lower lip with her teeth a little. She whispered, “He fucked me last night.”

Kristin made a shocked face and then laughed, “Oh my god, Madison.”

I moved around behind Madison, hugging her from behind and nibbling her ear, “and I’m fucking her again tonight.” My hand wandered down between Madison’s legs.

Kristin had mischeivous grin, “It’s not fair that Chris is telling people you fucked me and I didn’t even get laid.”

“I could fix that.”

Kristin’s hand was wandering around Madison’s bare ass and then gripped my dick. They kissed some more. I stepped back from them and then moved so that my erection poked out of the water. They looked at it and giggled. I moved near them, so my dick was near their mouths. Madison sucked on it first. Kristin’s eyes were wide, watching her suck my dick, right in her face. She pulled her mouth off, my dick springing up. Then Madison grabbed my dick and aimed it for Kristin’s mouth. Kristin opened wide and my dick went in. She slurped on it greedily, then let it slip out.

Madison said, “I’m getting too hot in this hot tub. Let’s go inside.”

We got out and dried off. The girls wrapped themselves in towels and ran up the stairs giggling. When I caught up to them, they were rolling around naked on my bed, making out and giggling. I hopped onto the bed, behind Madison, so she was like the middle of a sandwich. My hands wandered all over both of them as they kissed. They stopped kissing and Kristin and I kissed a little. Then, Madison took over, turning to kiss me over her shoulder.

Kristin moved down to suck on Madison’s tits. Madison was startled and stopped kissing me, so we both looked down at Kristin, as she sucked on Madison’s perky nipples. They were breathing heavy and there were some embarrassed giggles. Kristin looked up at us, completely red faced, and stared kissing and licking her way down toward Madison’s crotch. Madison bit her lip and looked at me nervously. I squeezed her tits gently and humped my boner into her bare ass.

Madison rolled more onto her back, as Kristin made her way closer to her pussy. Madison was breathing rapidly from excitement, as Kristin kissed her mons, then looked up at her while licking her slit. Kristin giggled nervously with her tongue on Madison’s pussy. Madison clutched my arm and said, “Oh my god,” as Kristin continued licking her. I could feel a little precum leaking out of my dick and Madison grabbed it, rubbing the precum around a little. Madison’s legs were spread wide and Kristin was really getting into licking Madison’s clit. I saw her grin up at Madison, spreading her labia, and fingering her. Then licking her clit some more.

Madison was breathing hard and whimpering, “holy shit…”

Kristin gave a satisfied grin at Madison’s reactions and then more aggressively licked and sucked on Madison’s pussy. She was making horny sounds, as she ate her out. Madison had an orgasm, “Kristin…holy shit…Kristin…” Her chest rising and falling.

Kristin licked her into some more small orgasms, then moved up her body with an almost sheepish look. Then they kissed some more.

Madison nervously said, “How was that?” giggling.

Kristin gave an embarrassed giggle and shrugged, “Fun.”

Madison slowly pushed Kristin onto her back and made her way down between her legs, both girls giggling nervously. Then Madison went down and furtively licked between Kristins legs with Kristin and I looking down at her. My hand roamed around Kristin’s naked body and my dick was against her side. Madison was really getting into licking Kristin, but kept looking up nervously.

My dick was so hard, it felt like the skin might tear, so I moved up into a kneeling position with my dick near Kristin’s mouth. She turned and opened her mouth, sucking it, as I fucked her face a little. She kept getting distracted by Madison’s pussy licking and would pull her mouth off and jerk me off a little. Madison gave us a devilish grin while fingering and licking Kristin.

Kristin wasn’t doing a very good job stroking or sucking me, too distracted by Madison’s work. So, I moved down behind Madison and slipped my dick into her pussy. She was face down in Kristin’s pussy and I pulled her into ass up, fucking her doggystyle.

Madison pulled her face off Kristin’s pussy, distracted by my thrusts, but Kristin grabbed her and held her face down there, grinding herself on Madison’s lips and tongue. I held Madison by the hips and fucked her hard from behind. She grunted and moaned into Kristin’s pussy. Kristin had a loud orgasm and then I came deep inside Madison. Madison crawled up Kristin’s body and snuggled with her I moved up there too and we all laid there in a naked tangle. We were smiling at each other and kissing some.

I finally broke the awkward silence, “Well, that was fun.”

The girls both giggled at that. I was looking down, Kristin’s lean body and made my way down between her legs, licking her pussy. They both enjoyed watching me, but I thought I detected a hint of jealousy from Madison’s expression. Pretty soon, Kristin’s pelvis was rolling around in time with my licks.

We were interrupted by the startling sound of the garage door opener. They were back from their errands. Madison hopped up, “shit they’re back. Get dressed.”

Madison headed toward the bathroom and Kristin said, “We don’t need to get dressed.”

I turned from my licking and saw a jealous expression on Madison’s face. Kristin said, “It’s less suspicious if Sam and I are fuckjng when they get back. Madison grimaced a bit with jealousy, but said, “Yeah, that’s probably true.” Madison went in and I heard the shower come on.

I ate Kristin out until she orgasmed, then slid up her body and slipped my dick inside her. She made loud grunts and moans as I fucked her. Partially because she was enjoying it, but probably also figuring that it would be good if people thought we were fucking. I lasted a long time, since I’d already fucked Madison three times that day.

I was still fucking Kristin, when I heard the water stop in the bathroom. I heard Chris, back from the store, in the bathroom with Madison.

“Hey Mads, we’re back.”

“Oh, hi babe.”

“Is that a hickey on your neck?”

Madison hesitated and said, “I guess you don’t remember doing that last night?” She was good.

He said, “Man I was pretty hammered.” He was quiet, then giggled, “Is Sam fucking someone in there?”

“Who do you think? I told you he was gonna fuck Kristin. I knew she would fuck him.” She sounded jealous.

“Damn…at least someone’s getting laid.”

“You could be getting laid…”

“Man, Mads, I want to…it’s just…you’re right about the booze and the smoking and stuff.”

“Seems like Sam’s not having a problem getting hard.”

“Fuck. Now I’m paranoid I won’t get hard. I’m all in my head.”

“Don’t worry about it. Just enjoy the weekend. Take a break from the booze and masturbating and then fuck me a few days from now. I know you’ll get hard.”

“Okay.”

I was still fucking Kristin hard. I was up on my knees, pinning her legs wide open with my hands on her thighs, watching my dick go in and out of her pussy. As I got closer to cumming, she whimpered, “Come here…” opening her mouth and licking at the air. She was kind of pulling me up towards her face. So, I moved up her body, straddling her with my boner right in her face. I stroked it some and then she grabbed it to put it in her mouth. Her head was propped on a pillow and she put a hand on each of my butt cheeks, as I braced myself with my hands on the headboard and fucked her mouth.

Despite how hot this was, I was having a hard time cumming, after having so much sex. I pulled my dick out of her mouth and she licked it. I stroked it quickly right in her face and she moaned, “Do it…cum on my face…” I felt her hand moved under me, so that she could fiddle with her own clit. I put my dick in her mouth a little more and she moaned on it. I pulled out again, jerking off and then moaned loudly, as I shot a small, watery load on her lips and cheek. She whimpered out a strained, high pitched, “oh my god…” and squeezed her hand between her legs.

The door to the bathroom opened and Madison was standing there in a bra and panties with wet hair, “Chris went downstairs.”

I climbed off Kristin’s chest and she hopped up, walking toward Madison in the bathroom. Madison seemed to be jealously eyeing the cum on Kristin’s face and then giving me a look. Kristin bent over the sink to wash the cum off her face and I walked towards the bathroom. Madison was still giving me a jealous look.

“What’s wrong, Madison?”

Kristin sat on the toilet, behind us, peeing. Madison hugged me and kissed me, “Nothing.” She kissed me some more, “I loved the threesome, but I got a little jealous with you two fucking without me.”

“Sorry…we were sort of in the middle of it when Chris came up.”

“It’s okay, it was good cover.”

Madison turned to Kristin, “You aren’t going to tell anyone about this…”

Kristin laughed and came over to us, “I won’t tell anyone, but you guys are both mine tonight.”

Madison grinned, “Okay friend.”
