Skinny dipping with my FWB and her best friend turns into a quick threesome that we'll never forget

This one takes place about 3 years ago. If you've read any of my previous stories, you're probably familiar with Vicky. If you're not, let me fill you in: As a grad student, I taught one semester of math to freshman college students, one of whom was Vicky. We matched on Tinder during finals week, had a good time, and eventually had a long relationship that is far too complicated to describe here. Sometimes exclusive, sometimes open, sometimes more like friends-with-benefits, sometimes long distance sexting buddies, and everything else in-between. At the time of this story, we were comfortable just being FWB.

I was feeling a bit horny one night, so I sent her that one gif of the dude with a mustache raising his eyebrows and it zooms in closer each time. I'm sure you've seen the one, if not, Google it and you'll know what I mean. That was sort of our own little shorthand for "let's get it on" when we didn't really care about all the formalities. The customary response was the gif of Robert Redford with a beard nodding and smiling if it was a yes, or the gif from The Wire of Bunk shaking his head and walking away if it was a no. Things were very simple for us, to say the least. About an hour after I sent the gif, I get a text.

"at a party, wanna come down?"

I agreed, and she told me it was at her friend Melissa's house. Melissa was Vicky's best friend and former roommate. One of those things where they were randomly paired together freshman year and formed an incredible bond. In fact, Melissa was also a student of mine in the same class as Vicky, and I awkwardly ran into her when leaving their dorm after the first time Vicky and I hooked up.

"Don't worry, I'm not gonna tell anyone," she had told me. From that day forward, I kind of came to expect that anything Vicky and I did, Melissa knew about it shortly after it happened. That's just how the two of them were, and I was okay with that.

Melissa was living at a house that she rented with two other girls and the one girl's boyfriend. It was a small place but it had a nice big backyard with a pool, making it kind of a hot spot for parties within their friend group. I'm not 100% sure what this event was about but I'm pretty certain it was a going away party for one of their friends who was moving out of state. It's California, that happens a lot.

I immediately went and found Vicky, who was wearing a bright red dress that pushed her tits tightly together and ended just below her pussy. Her long tanned legs were a sight for sore eyes. Vicky was about average height, maybe a little taller, with hazel eyes, brown hair down past her shoulders, and a runner's tight body. She wrapped her arms around me, got on her tippy-toes and gave me a kiss.

"I'm so glad you're here, these dudes are fucking annoying," she said. I looked around and caught the eyes of one guy who nudged his buddies and said something probably along the lines of "never mind, she's taken." She handed me a beer that she'd been holding until I arrived, then we walked out to the back patio where she was hanging with a few of the other girls. We drank and smoked, played games and chatted, and just generally had a great time. As the night wore on, everyone started to leave until it was just me, Vicky, and the people who lived in the house. We cleaned up and the other housemates slowly went off to bed, leaving just the three of us.

"I'm sad no one used the pool, we got it all cleaned and heated," Melissa said.

"No one ever mentioned bringing a suit or I would've," I said.

"I completely forgot to bring something," Vicky said.

"I doubt anyone would've complained if you went in with nothing on," I teased.

"Trust me, those guys don't need any more jerk-off fuel," she responded.

"Yeah Vic, give 'em a show!" Melissa said.

"I mean, you both have seen me naked, I wouldn't mind a little night swimming," Vicky said. "What do you say?"

"Yeaahhhh let's do it!" Melissa shouted.

They both looked at me. I focused on Vicky and tried to telepathically explain the potential awkwardness of us all getting naked together. She rolled her eyes and told me to just do it, then started lowering the straps off her dress. Melissa followed.

Melissa was a pretty tall girl, taller than Vicky at least, ginger red hair, freckles, pale skin, very skinny and less toned than Vicky. She pulled off her dress to reveal perky little tits underneath that held on tight to her body. I tried not to stare and just focused on getting my clothes off as they jumped right in the water.

"I love feeling the water on my bare skin," Vicky said. "It's so freeing."

I got in the water after them, and we swam around for a bit. Splashed each other in good fun, showed off how fast we could do laps from one side to the other, and eventually just sat in the water talking normally. Vicky and I ended up leaning against the wall together in the shallow end. She pressed her ass against my cock and grinded on it ever-so-slightly. I reached my arm around her in an embrace and squeezed her tits, rubbing her nipple between my fingers to arouse her.

"Get a room!" Melissa said playfully.

Shortly after, she got out to use the restroom. I peeked at her ass as she walked up the steps and out into the air, where she took her time drying off and covering up before walking into the house.

"I saw that," Vicky said. "You're lucky I'm not the jealous type."

I grabbed a hold of her and brought her in close. "I was hoping you were," I said, giving her a kiss. "Maybe make you wanna do something to win back my attention."

"Yeah? Like what?" she asked. She reached her hand down and stroked my hardening cock under the water while we made out.

Melissa returned shortly with a big grin on her face, closing the sliding door behind her. When she saw us, she threw her hands up.

"Not you, too!" she exclaimed.

"Not us what?" Vicky asked.

"Carlos and Sophia are in their room trying to knock the house over the way they're going at it," Melissa said. Carlos and Sophia were her housemates, and as she went on to tell us, were not quiet about their lovemaking, especially after a night of drinking and partying. She went over to the table and lit up another bowl, prompting us to get out of the pool and join her. Rather than grabbing towels, we just let everything hang out in the open as Vicky sat on my lap.

"Well now I feel left out," Melissa said, dropping the towel that had been covering her body.

Vicky playfully covered my eyes and said, "don't be checking her out again."

"Again?" Melissa teased. "What, she's not good enough for you? Look at that fucking body! She's a fucking snack!"

"Thank you! I am!" Vicky said.

"You know normally if I said I had two naked girls teaming up on me, that would be a good thing, but I don't like this very much," I said.

"You deserve it," Vicky said.

"Oh, blow me," I responded.

"Don't tempt me, I just might."

"Do it! Do it!" Melissa urged, pumping her fists.

Vicky looked at me for a moment, then slid off my lap onto the concrete below. She took my cock in her hand and pulled it back into her mouth. I looked up at Melissa, who was smoking a little extra before looking down to watch.

"Get it! Work that tongue!"

Vicky bobbed up and down in my lap, placing one hand around my thigh and the other on my chest. I tried to get into the moment, but I'll admit it was a little weird to start. I think she sensed it as well because she took my cock out of her mouth and told Melissa, "if you think it's so easy, get down here."

After a short pause where I think everyone was considering if this was the way the night was going, Melissa did as Vicky said. Vicky shuffled over to the side and let her get in and start sucking. She was very timid about it at first, just licking around the head and sucking shallow, but she eased into it and started going full throttle soon enough. Her long red hair kept falling in front of her face, so Vicky held it back for her.

"You like that?" Vicky asked me. I nodded. She stood up next to me, still holding Melissa's hair, and gave me a kiss. We started making out, and I slipped a hand between her legs to finger her. It was all a strange mess of bodies all touching one another and probably looked ridiculous from the outside looking in.

Finally, I tapped Melissa on the shoulder. She lifted her head and looked at me inquisitively.

"You girls wanna take this to the bedroom?" I asked. They shared a glance and a smile, then hurried into the house. We all got into Melissa's room and the two girls got down on the bed.

"Who goes first?" Melissa asked.

"You should, I get this all the time," Vicky responded.

Melissa bent over, sticking her ass up in the air for me. Vicky gave it a good slap as I slid my cock in. Her pussy gripped my cock as I thrusted in and out.

"Moan for me," Vicky told her with another slap. She was sitting beside us, fingering herself.

Up until that point Melissa had been quiet, I think a little shy, but once she had encouragement she really let herself go. She was moaning louder and louder each time her ass slapped against my stomach.

"I'm gonna cum," she announced. She fingered herself as I kept working her with the same speed and strength until she came. Almost immediately, she flopped down onto the bed and turned over. "Your turn," she said.

I took a deep breath to regain my energy as Vicky got into the same position. Her and I, knowing each other's bodies so well, took no time getting into the motions we knew we both liked. Melissa's chest heaved with each breath as she touched herself lightly to our fucking.

Vicky didn't hold back at all, as she almost never did, and was screaming in short time as she pushed her ass back into me. I wrapped my hands around her waist and fucked her as hard as I could until she came. I kept fucking her for another few strokes before she stopped me and rolled onto her back as well. The two girls lay there, side by side, giving me the choice.

I continued fucking Vicky for a few more strokes until I slid back between Melissa's pale legs.

"Are you on the pill?" I asked. She shook her head no. I pulled out and stroked my cock until I came across both girls. I'm not gonna exaggerate this by turning it into some kinda porno and say it was some ungodly amount, but it was enough that they each got a few shots on their stomachs.

We all passed out shortly after and slept it off. In the morning, we had a horrifying realization: all our clothes were still out back. Melissa dressed herself and went out to grab them, but we were caught. Her other roommate was already wide awake in the living room watching TV and nursing a hangover.

Oh well, now they know what they missed out on by going to bed early.
