Everyone changed into swimsuits and got in the pool. Matt’s parents and some other older wedding guests were staying at the house that night, so there was no skinny dipping that night. I got in the pool and Maeve immediately got on my back. Madison was glaring at this situation, but she was sort of standing near a pool edge and Chris had his arm over her shoulders. I was feeling pretty jealous, which was ridiculous, since he was her boyfriend, not me.

I sank myself into the water to dunk Maeve and she popped back up wrestling with me. She kept trying to dunk me, so I grabbed her and lifted her over my head. I had to have one hand between her legs, on her crotch, and the other was on her chest, basically pressing her over my head. I threw her down into the water and Chris was laughing.

Chris tried to pick up Madison like that and she even tried to help him, but he couldn’t do it. He gave up saying, “I forgot about my shoulder,” as he rubbed one of his shoulders. Madison came over to me, “Can you do it?” She was giving me those fuck me eyes again. I picked her up the same way I’d picked up Maeve, with my hand between her legs, right on her pussy, feeling it through her bikini bottoms. I held her over my head, as she laughed and then slammed her into the water. Chris looked irritated and took a sip of his drink. He made a fake laugh pretending he didn’t care. Madison came up out of the water and grinned at me. Maeve was looking over a bit annoyed that I wasn’t paying attention to her.

Kristin swam up, “Me next.” I did the same to her. Maeve came back over, “Can you lift me up on my butt? Like a cheerleader?”

She sat on my hand and I boosted her up over my head then through her in the water. She swam underwater right up to me and wrapped herself around me in a tight hug. I helplessly looked at Madison who looked pretty irritated. I was getting hard from feeling Maeve’s slippery skin on me. She noticed and moved her crotch on mine a little. I walked into deeper water to get her off me.

It got late and thankfully Maeve got too drunk to be very aggressive with me. She actually disappeared somewhere in the house, presumably finding a bed in the big house. Other people left and the pool emptied out. Eventually, Kristin, Madison, and I were the last ones outside and we went into the outdoor shower to rinse off the pool water. The three of us took turns making out with each other and our hands wandered in the dark shower. I had a hand on each of their asses, while we took turns kissing each other.

Madison and Kristin were tongue kissing each other and making quiet moans into each other's mouths. I got behind Madison and was enjoying sticking my hand in the back of her bikini bottoms to feel her perfect ass. I sat down on a wooden bench in the shower stall and pulled down on Madison's bikini to expose her beautiful ass. I groped her butt cheeks and then spread them to lick her asshole a little. She whimpered into Kristin's mouth. I saw Kristin stop kissing her and look down at what I was doing.

Kristin giggled and whispered, "You're rimming her?"

"Yes, you should try it."

Kristin was nervously giggling and looked at Madison, who also giggled. Kristin slowly sat down next to me and put her hands on Madison's cheeks. She kept cracking up, and Madison wiggled her ass in her face. Finally, Kristin furtively moved in and lightly touched her tongue to Madison's sphincter, which caused both of them to giggle, but pretty soon they were both getting into it.

Just as they got into it, I heard Chris outside the shower, "Mads?"

Kristin made a pouty face and pulled Madison's bikini bottoms back up. The three of us left the shower stall to find Chris waiting outside. He pulled Madison aside, "What were you guys doing in there?"

She looked at him like that was a stupid question, "Rinsing off the pool water."

"But, like, the three of you?"

"We had our swimsuits on and it's a big shower stall. I was just in a hurry to rinse off, so I can go to bed. Busy day tomorrow."

"Okay, well, why can't I stay here with you, Mads?"

"I don't know. Heather wanted the wedding party here."

Chris reluctantly said, “I guess I’ll get a car to come get me.” He made a call and soon a town car came to pick him up. Madison gave him a kiss and a hug goodnight.

Madison, Kristin and I went up to their bedroom, tip toeing and trying to be quiet because most people were in bed already, but giggling a little on the way. As we went up the stairs, I walked behind both girls and slid my hands up between their legs from behind and they both made surprised giggles, when my hand touched their crotches. "shhhh...ladies, people are trying to sleep."

When we got into their bedroom, we locked the door and the swimsuits quickly came off. Kristin got on the bed on all fours and said, "Eat my ass Madison," and she giggled. Madison crawled onto the bed behind her and dragged her tongue up her slit before licking her puckered butthole. I moved to the head of the bed, positioning myself in front of Kristin. She took the hint and started sucking my dick, as I leaned against the headboard. I was watching Madison get into licking Kristin's pussy and ass from behind.

Kristin crawled up my body to sink herself down onto my hard cock. Madison moved up behind her and licked her butthole, while Kristin bounced up and down on my dick. I felt Madison's tongue on my balls and shaft a little. After Kristin rode me for a bit, Madison said, "You're hogging the dick, Kristin," and playfully pushed her. Kristin climbed off my dick and Madison replaced her. Kristin positioned herself over my face, so I could lick her pussy from below, while Madison fucked me.

The room was alive with the sounds of our pleasure and pretty soon, I came inside Madison, "fuck yeah...Sam..." and she just kept grinding on me. I was still hard and her pussy was even slicker with my cum, so she fucked me a bit longer. Madison's legs got tired and she got off of me and went to pee. I was quickly on top of Kristin, banging her in missionary. Madison came back and sat on Kristin's face, while I continued banging Kristin.

I had an idea and I slipped my cock out of Kristin's pussy. "I want you two on all fours, right next to each other, here."

They both giggled and obliged me by getting in doggy next to each other. I entered Kristin first, thrusing a few times, then pulling out and moving over to bang Madison. They kissed each other as I went back and forth a few times, taking turns with their pussies. I got sick of switching and just banged Kristin from behind, so Madison moved to put her pussy in front of Kristin. Kristin ate her out, while I fucked Kristin hard. I came deep inside Kristin and then pulled out, collapsing on the bed, next to Madison. Kristin got up to go pee and Madison and I made out on the bed.

My dick was semi hard, but Madison went down on it, getting it fulling hard in her mouth. Kristin came out and said, "How do I taste, Madison?"

Madison laughed and gave her the finger, while continuing to suck my cock. She stopped and flopped over on her back, masturbating a little. I stroked my own dick and then stood up. "Come here ladies," and I stood by the edge of the bed. They knew what I wanted and they laid there with their mouths available for my cock. I moved back and forth, fucking Kristin's mouth and then Madison's. They flopped on their backs and both of them masturbated, while I used their mouths. Kristin climbed ontop of Madison, making out a bit, while I stroked myself. Then she stopped kissing her and opened her mouth, wanting my dick in it. I gave it to her to suck it a bit, but then Madison grabbed it and sucked it. They were grinding their pussies against each other and taking turns with my dick. I finally jerked off onto Madison's open mouth and then Kristin moved down to have a cummy kiss with her. The three of us eventually cleaned up and went to sleep in a tangle of naked flesh.

After my night with Kristin and Madison, I went into the bathroom between the two bedrooms to brush my teeth. I opened the door to my bedroom on the other side of the bathroom and was standing there naked, digging in my overnight bag for some clothes, when I noticed my bedsheets moving. Maeve sat upright in my bed, holding the sheets around her with her bare shoulders exposed. She looked hungover and bedraggled, but smiled at me, “I was waiting for you in here. Where were you?”

I lied, “Um…uh…I passed out on a couch downstairs.” I couldn't let her know that I'd had a threesome with her engaged sister the night before.

She gave me a little smile and dropped the sheets to show me her perky tits. I stared at them in shock. “Uh…Maeve…um…”
