When I was early 20's I dated a girl who really liked sex. Most my friends were the same. Honestly who isn't a sex addict in their 20's.
Me, my girlfriend, and my friends used to go camping in this spot where the canal crossed the river at the aqueduct. We would swim in the river and fish the canal while camping all weekend. The river wasn't very deep, only 2 or 3 feet deep at the most in some spots with lots of sandbars.
Me, my girlfriend, and another couple went out one weekend to camp and get away. My buddies girlfriend is a redhead and I had always wondered if the curtains matched the carpet. That weekend I found out they did.
All four of us were in the river swimming and cooling off from the heat of the day. That's when my girlfriend stripped off her bikini, held it up for all to see and then threw it up on the bank. My buddies girlfriend followed and threw her bikini next. The girls then chastised us until me and my buddy did the same and removed our trunks.
My girlfriend came over and started rubbing my dick. It wasn't long before I had her from behind with my dick in her. We had been in 3 feet of water, so still somewhat submerged at this point to where we couldn't see anything, but as we fucked we moved closer to a sandbar. That's when I noticed my buddies girlfriend more out of the water. She had a fire red patch that matched her red hair. Mistry solved, I thought to myself.
Not long after I saw my buddies girlfriend completely naked, we were all four on the sandbar fucking next to eachother. My girlfriend, the little devil, decided it would be a good idea to swap and asked if we all wanted to. My buddies girlfriend right away said yes. Me and my buddy took a few minutes to agree.
We got up and switched partners. I quickly started fingering her fire red pussy. She was warm and wet and moaned the instant I shoved my fingers in her. She meanwhile grabbed my dick and started stroking it. I rubbed her tits with my other hand. Her perky perfect tits with milky white skin and raspberry nipples that were barely visible from being the same color as her breasts. I sucked her nipples and they quickly popped up like little gemstones.
After several minutes of foreplay, I moved to position myself between her legs. As I did, I looked over and saw my buddy already plowing away at my girlfriend. I could tell they were both enjoying themselves and cared less what we were doing.
I positioned my dick at her wet pussy and with some effect, pushed my dick completely in her. She gasped and arched her back with pleasure as I penetrated her. Her mouth was open and her eyes closed as she held my ass in her hands. A few seconds passed before she finally took a breath and begged me to fuck her.
I did as she asked and fucked her pussy to orgasm. The whole time she would claw my back and moan like a wild woman until she finished with a screaming orgasm as she call out "oh God, yes" over and over again. Her screams of ecstasy was more than I could handle and shortly after she finished, I unloaded deep inside her with groans of my own.
With my dick still inside her we both stared into eachothers eyes. The chemistry was unmistakable and for a moment I thought about kissing her. The look in her eyes was unmistakable and I knew she was screaming inside for me to kiss her.
I instead broke eye contact with her and we both looked to the side where our partners had both finished and were watching us in amazement. The look on their faces was unmistakable shock as they both asked "WHAT THE HELL" at the same time. I figured now would be a good time to remove my dick from her pussy. I slid out and sat beside her waiting for the barrage of word from my girlfriend, or buddy, or both.
Luckily the barrage never came and we finished the weekend without any issues. We also never swapped again, which was disappointing as I really did want to make her orgasm again. I would get my chance in due time though.
Less than a year later I would break up with my girlfriend. Not long after, my buddies girlfriend would break up with him. She and I started dating and moved in with eachother. My buddy and exgirlfriend accused us of having an affair when they found out we were dating. They tried to say we never stopped seeing eachother after that weekend, even though we never did anything afterwards. They were just jealous of the chemistry she and I have together. I knew that weekend pissed them off, eventhough they never said anything.
