Kristin turned on the shower and climbed in. Madison continued getting dressed, doing her hair, etc in the bathroom and I got in the shower with Kristin. Kristin was facing the shower stream and I grabbed her nice, firm ass. I got a devious idea and aimed my dick at her, and started peeing on her bare ass. Kristin giggled and said, “Dirtbag,” but she spread her ass cheeks for me to pee between them. Kristin yelled to Madison, “He’s peeing on me.”

Madison yelled over the noise of the shower, “Don’t you guys have too much fun in there without me.”

After I finished peeing, she rinsed off. Madison left the bathroom to finish getting dressed. Feeling Kristin’s slippery, soapy tits and ass, was making me sort of hard again. After we got clean, we hugged and kissed a bit in the shower stream. She gave me a sexy grin and squatted down, taking my partially hard dick in her mouth. She throated it and looked up at me. She pulled her mouth off, played with a little and throated it a few more times. She had my dick all the way in, her lips were at the base. I was not really ready for another full blown session and I think neither was she, but she just enjoyed putting it in her mouth some.

Madison came back in and saw that Kristin was on her knees with my dick in her mouth. She cleared her throat loudly and opened the sliding glass door to see. “I thought I said not without me.”

Kristin stood up, “sorry. I just love sucking cock.”

“Everyone knows that about you Kristin.”

Kristin gave her a fake angry expression and then laughed. We got out of the shower and dried off. Kristin didn’t have any clothes in my room and had to go down the hall in a towel to the room she stayed in the night before.

I got dressed and went downstairs. More people showed up for the party and there were people gathered in the kitchen, outside near the pool, in the TV room, in the basement, and even in the driveway. It was a big party and it was easy to disappear into the crowds.

I was hanging out with Matt and Heather, near the pool. We sat in chairs, talking and drinking. Kristin showed up and plopped herself down in my lap because there were no chairs available. Kristin was wearing a tiny denim skirt, that barely covered her ass and a tiny top that showed off her bare midriff. She was draped sideways across me. Chris was standing playing beer pong, maybe 50 ft away and Madison was hanging out with him, trying to be a good gf.

Chris saw Kristin in my lap and grinned. He gave me a little head nod and I raised my beer at him. Madison looked slightly annoyed and jealous that Kristin was on me. Kristin gave sort of a sexy look in Madison’s direction and yelled, “I love you Madison,” raising her drink toward Madison.

Madison smiled at that a little and raised her drink toward Kristin. Heather was looking a little perplexed that Kristin was in my lap, knowing full well that I was banging Madison. Kristin even leaned in and kissed me a little. I saw Matt raise his eyebrows probably wondering if I was actually pulling two girls at once. My hand rested on Kristin’s smooth upper thigh. I couldn’t help but lightly move it up and down a little, as we chatted, even up into her skirt, grazing her panty covered crotch. Everyone was buzzed and it was now dark out, so that was less obvious.

A friend came to grab Kristin to do a shot and she got out of my lap. Madison saw that and took the opportunity to come sit in my lap. Chris looked disturbed to see me running my hand up Madison's outer thigh and up into her skirt a little bit onto her hip and ass. We hung out chatting with Matt and Heather and eventually Chris came over, looking irritated that Madison was sitting in my lap.

“Mads, come here a second?”

Madison got up and they walked slightly away, but I could hear/read their lips some.

“Mads, it’s weird you’re sitting on Sam’s lap like that…”

“What? There was nowhere to sit.”

“But like, he had his hand on your butt. You’re just sitting on this dude’s lap.”

“Chris, he’s like a brother or something. Like an annoying brother. He’s just a fun friend.”

Chris was looking annoyed. “And I don’t like that he calls you stinky. Like what’s with the cutesy nickname.”

“Cutesy?! He’s being like a little pest calling me stinky. You think I like being called stinky? He’s like an annoying brother. Besides he’s just a fuckboy. Dude, he’s fucked Kristin god knows how many times this weekend and I wouldn’t be surprised if there was another girl.”

Chris smiled sheepishly a little, “So, he’s definitely fucking Kristin?”

“She’s been bragging about how much dick she’s getting from him this weekend. And, he was telling me all about the sloppy blowjob she gave him.”

“See, why would he tell you that? That's weird.”

“To be an annoying fuck boy.”

Chris was looking at me and Kristin came back to sit in my lap. “She does give sloppy head.”

“How would you know?”

“Uh…I’ve heard it from enough guys.”

“So, are you feeling better about Sam?”

He sheepishly said, “Yeah, sorry. It’s just you’re so hot and I mean it’s hot in a way seeing you in his lap or whatever, but it also makes me jealous.”

Madison smiled, “You think it’s hot?”

“I don’t know, it’s like a little hot. You were just running around naked in front of him today and shit. Don’t get any ideas.”

She giggled nervously, “He’s just a goofy friend. Look, he’s got his fucking hand up her skirt right now.” Madison looked actually annoyed at that.

Chris giggled, “I can see her panties.”

Madison smacked his arm.

He kissed Madison, “Alright, sorry, it’s all in my head. It’s just you’re so hot. I’m gonna go play some beer pong.”

Madison came and stood in front of me, with her arms crossed in an exaggerated pouty expression, “I was sitting there.”

Kristin said, “You got up.”

I was in a big Adirondack chair and Madison plopped herself down on one of the wooden arms. I put my arm up, with my resting on/caressing her ass a little, as she sat there. I could look over and see that Chris could see where my hand was. I put my other hand up in Kristina’s skirt. I pulled aside the crotch of her underwear a little, in a way that only Madison would have gotten a flash of her pussy, looking down. Heather and Matt were talking to other people and not paying attention to us.

I said to Kristin, “Hey, pussycat. Can you get me a drink? I’m trapped.”

“Okay,” and she got up. Madison immediately slipped into her spot and she looked back angrily, then laughed.

Madison draped herself sideways across me. She leaned into whisper in my ear, “You know, Kristin isn’t the only one who can throat cock.” She gave me a jealous look.

“You’re jealous she was sucking my dick in the shower?”

“Yes, and sitting on your lap.” My hands wandered around her body a little and I caught Chris glancing at us from down at his game.

“You’re cute all jealous, Stinky,” and I tickled her, causing her to laugh really loud, so that caught Chris’s attention.

She was wearing a very short, summery skirt and I slid my hand up in it, but on her outer thigh and up to her butt. Chris kept looking over with a tense look. I squeezed her ass cheek and leaned in to whisper in her ear, “Maybe I should fuck this ass tonight.”

She giggled and shrugged.

Chris waved her over to him and she hopped up, grabbing him a beer on the way. She gave him a cheery smile and he hugged her possessively. I swear he looked at me, as he groped her ass, even sliding his hand up the back of her skirt, exposing her some. She giggled and pulled down her skirt. After that, he held her a bit, with her in front of him and him hugging her from behind. He let his hands wander and I saw him squeeze one of her tits possessively.

Kristin and I wandered over there, sipping drinks. We chatted with Chris and Madison some. It seemed like he was making it a point to touch her as much as possible.

I finally said, “Hey Stinky, pussycat and I were thinking about going for a smoke.”

Chris burst out laughing, “Why do you call her pussycat?”

“Why do you think?”

He laughed and high fived me. Kristin blushed, giggled and shrugged.

Chris laughed and said, “Dude, you’re alright man.”

Madison said, “Where are you going?”

“I don’t know just wandering around. She’s got a joint.” Kristin held it up.

Madison looked at Chris, “want to come?”

Just then one of Chris’s bros said, “Dude, come here. We’re doing a beer funnel.”

He looked at Madison, “I’m gonna go do this beer funnel.”

I said, “Mind if I steal your girl for a bit?”

Madison was looking at him expectantly and he said, “Yeah man, like whatever, you guys enjoy that bud,” and he laughed and kissed her.

We walked around the yard passing the joint back and forth between the three of us. We got around the front of the house and there were cars parked everywhere. We decided to get in my car, with the three of us in the back seat, listening to music. We took turns making out with each other. I had Madison on one side and Kristin on the other.

As I kissed Madison, I felt Kristin move so that her legs were across both of our laps. Madison stopped kissing me and ran her hand up Kristin’s leg. She snuck a finger past the crotch of her panties and fingered her a little. Kristin reached down to fiddle with my zipper, unzipping my shorts and pulling out my hard cock.

Madison moved to bend down and suck my dick. She sucked it some, but the way we were sitting, my dick was between Kristin’s legs and near her pussy. So, Madison moved slightly and pulled aside Kristin’s panties to lick her pussy some. Kristin giggled. Madison went back to sucking my dick and I said, “I thought you said you could throat it.”

Madison made a muffled laugh with my dick in her mouth and went as far as she could, gagging a little. I saw Chris walking around with a friend out the window. “Oh, hey, Chris is out there.”

She pulled her mouth off my cock and lifted her head to look out the window. She had watery eyes and her lips were wet with slobber and swollen. She made eye contact with Chris. I could see his facial expression change to shock, with her head obviously coming out of my lap.

Madison tried to play it cool, sitting upright and waving at him. I quickly tucked my dick back into my shorts. Madison quickly got out of the car and ran over to Chris, “Hey, babe, we smoked the joint already.”

I stayed in the backseat with Kristin and just made out. Chris kept looking over. He looked suspicious, “Your eyes are like all watery.”

“I was smoking weed.”

“Mads, I mean. It really looked like…I mean…it looked like you were giving Sam head, when I walked up. I thought I saw your head bobbing up and down.”

She laughed and lightly smacked his arm, “Hahahahaha…that’s crazy. I dropped the joint as we passed it around and then I bent down to pick it up.”

Chris looked like he bought that, he smiled and laughed, “Fuck, it really looked…you should have seen it.”

I had my hand up Kristin’s skirt, fingering her, and making out with her.

Madison looked our way, jealously, “No, but those two can’t keep their hands off each other. I was like the third wheel.”

Madison snuck up to bang on the car window, yelling, “Police…”

Kristin and I got out of the car, and I chased after Madison, “What are you jealous, Stinky.”

I caught her and picked her up and then wrestled her to the ground. Chris was watching and awkwardly laughing, as I pinned her down on her back basically in missionary. Her skirt was completely up, exposing her underwear. Madison was giggling, “Chris thought I was sucking your dick when he walked up.”

I laughed and looked over at him. I thrusted my pelvis into Madison a few times, “Nah man, that would be like fucking my sister.”

Chris laughed, as I got off of Madison and put my hand out to help her up. She took my hand and caught me off balance, sweeping my legs and climbing on top of me. She straddled me there in the yard and pinned my arms. I didn’t fight that.

Chris said, “You guys play fight so much.”

Madison got off of me and held out her hand to help me up, “That’s because he’s an arrogant dick.” She giggled.

I got off the ground and quickly threw Madison over my shoulder. Her skirt accidentally hiked up, exposing her ass in her underwear. I smacked her ass a few times, gently spanking her, before setting her down next to Chris, “Sorry, she’s dirtier than when I borrowed her from you.”

Madison had to rearrange her panties before pulling down her skirt to cover her underwear. Chris had a mix of jealousy and amusement on his face. I looked down at the hand I used to smack her ass, then sniffed it in an exaggerated way, “need to wash this now, stinky.”

I started walking towards the backyard, “Smells like butt.”

Madison was beet red and chasing after me, “No it doesn’t.” She punched me lightly on the arm, “Take it back.”

Chris was walking along with us, chuckling. The girls heard music in the backyard and ran ahead to dance, so Chris and I were walking alone together. He chuckled, “Man, I’m surprised you are still hooking up with Kristin. There’s lots of hot girls here.”

I looked over at him, “Yeah, but Kristin is a good time. You weren’t kidding about no gag reflex.”

He laughed and high fived me, “Yeah man.”

“”Dude, what about Madison? Are you just hitting that all the time?” He didn’t know that I knew quite well, that he hadn’t fucked her that weekend.

“Oh yeah, man, all the time. She gives great head too.”

“She’s really hot dude. Don’t tell her I said that though, you know, we have more of a brother and sister type of friendship. She’ll get all full of herself.”

He laughed, “alright man. So, you going after any girls other than Kristin?”

“Yeah, there’s one girl. We’ll see…I’m trying to see if I can get a little threesome with Kristin.”

He giggled, “Shit, who is it?”

I looked at him and said with a completely straight face, “Madison.” He spit out his beer in shock. I let it get quiet a minute, then slapped him on the shoulder, “I’m just fucking with you bro.”

He laughed, “Oh man, you got me, but seriously, who?”

“I don’t know. I’ve got know idea how to make a threesome happen.”

Just then, we walked out into the backyard and people were dancing on the pool deck. Kristin and Madison were dancing with each other in a suggestive way. They saw us and waved us over.

Chris turned to me, “Man, I really don’t feel like dancing.”

“I don’t love it, but I like girls and they like dancing.”

Chris came over and half heartedly danced with Madison a bit, but quickly left to go play a drinking game. Madison said, "Where are you going?"

Chris shrugged, "I don't really feel like dancing. You've got Sam and Kristin."

As he walked away, he looked back to see that Madison was grinding herself on me, facing me and I had my hand on her ass. She was looking right at him. He smiled a little and shook his head. Kristin came up behind Madison, grinding on her, so it was like a Madison sandwich. I kissed Kristin over Madison's shoulder and she gave me a jealous look.

Kristin grabbed Madison's hand and started leading her to the pool house. I followed along and looked back to see Chris saw us. I just shrugged in his direction, like I didn't know what we were doing. We went into the bathroom and locked the door. The girls started making out, leaned up on the sink and I let my hands wander all over the two of them. Madison slid down to her knees on the bathroom rug in front of the sink. She pulled aside The crotch of Kristin's panties and started licking her. I joined her down there and we took turns licking Kristin, as she leaned up against the sink counter.

There was a loud knock on the door. We paused and giggled. Madison licked Kristin some more. There was another knock, "Mads?"

Madison said, "Shit," and stood up. Kristin pulled her underwear back into place. I stood up reluctantly. Madison opened the door and Chris looked shocked to see the three of us in there together. We all left the bathroom and Kristin and walked away from them. I heard them talking.

"What the fuck were you guys doing in there?"

Madison giggled, "Kristin was showing us her tattoo."

"Why did you need to go into the bathroom?"

"It's kind of in a very private location."

"That's weird, like Sam, Kristin and you in the bathroom and she's like getting naked."

"She wasn't naked."

"That's all you guys did?"

"Yeah, you saw we weren't in there long."

He looked over at Kristin and me, suspiciously.

Madison yelled over, "Hey Kristin, can you show Chris your new tattoo?"

Kristin blushed and giggled. Chris looked excited and smiled. The four of us went into the bathroom and Kristin pulled up her skirt. She moved her panties down enough to expose the little tattoo she had near her pussy. It was just a little butterfly. Chris looked horny. Madison giggled. We all left the bathroom and went back out to the pool deck. Chris once again, left Madison behind to go join in a drinking game.

Madison, Kristin and I were quite horny from being interrupted. We made our way up to my bedroom, and quickly got naked. The girls got into a 69 position on the bed, with Kristin on top. I moved up onto the bed, on my knees, near Kristin's ass and Madison's face. I slipped my dick in Madison's mouth a little and then started fucking Kristin. I could feel Madison's tongue on my shaft and my balls sometimes, as she licked Kristin and me, while I thrusted in and out of Kristin. The girls were moaning and I could hear the sound of their wet lips and tongues on each other's pussies.

The bathroom door, between the adjoining rooms suddenly opened. I guess I forgot to lock it. It was a very drunk Chris. He immediately said, "Sorry dude...I was looking for Madison" and he giggled, "holy fuck..." and then he disappeared, shutting the door. I guess that in the dark, and since Madison's face was obscured between Kristin's legs, he could not tell it was Madison down there, licking my cock and Kristin's pussy. Madison pulled my cock out of Kristin and sucked it some, then guided it back in. When I was ready to cum, I put it back in Madison's mouth, fucking her mouth until I came.

We got up and cleaned up in the bathroom a bit. I checked the hallway to make sure Chris was not around and then Madison slipped downstairs alone to go pretend like she had not been with us. Kristin and I went downstairs separately. We ran into Chris outside and he pulled me away from Kristin. He had a huge grin, "Dude, I'm sorry for barging in. I was half expecting the door to be locked and I was surprised when it opened."

I laughed, "It's okay, Chris."

He whispered, "Damn dude. You did it. A fucking threesome." He high fived me.

I shrugged and sipped a beer.

“Who was the third?”

“Chris, I can’t tell you that. I’m sure the girl wants to keep that private.”

“Yeah, you’re right. Have you seen Madison?”

“I think I saw her down in the basement.”
