"Hey babe, Eric and Tina want to float the river tomorrow! It's supposed to be hot, can we go?" My wife Jill called out from the kitchen.
"Sure, I'm off! Let's do it. I'll pack a cooler and dig out the tubes."
My wife Jill and I have been married for 9 years and somehow she was always able to keep her body the same as it was when we met. Her perky C cup breast and tight stomach always turned heads at the beach.
Eric and Tina had been our friends for years. Tina was also quite a site in a bikini. She showed zero signs of ever having kids and obviously kept up her gym routine. This would certainly be a day of eye candy for Eric and I.
The four of us had always had a fun friendship with lots of flirting and teasing but nothing beyond that. I've always known Eric was hot for my wife and she enjoyed the attention. Tina had also never denied me the chance of a tight hug and friendly kiss upon hellos.
We used to hit the bars together when we first married but after kids it was rare that we got together just as adults, so we were all looking forward to a day in the sun.
The next morning we met Eric and Tina at the river so we would have two cars. One car at the put in and one at the take out ramp a few miles down the river.
When they showed up I could tell it was going to be a fun day! Tina was wearing a small white bikini pushing her breasts into the perfect cleavage. I swore that her bottoms looked like they would become see through as soon as she got wet.
Jill was also dressed for show! Her small black bikini left very little to the imagination and I could see her grinning as she noticed Eric drinking in the view of her as she climbed out of the car.
We said our hellos and our ritual hugs. Tina pressed me tightly and I could feel the warmth of her body as she kissed me hello. My cock immediately jumped from the smell of her body. Jill always smelled amazing but Tina just smelled different. It was intoxicating.
I noticed that Eric took full advantage of his hug, pressing himself tightly against my wife, and she was not pulling away.
"Ok, that's enough of that you two." I said. "Let's leave your car here and head up to the put in so we can get on the river!"
Eric locked up his car and we piled into ours. Tina immediately jumped in shotgun and since we were loaded down with tubes and coolers, there was only one seat in the back.
"I guess I'll have to sit in your lap Eric." Jill flirted, knowing he would love the idea.
I didn't mind. Jill and I had a healthy sex life and we both enjoyed the flirting that went on between the four of us. It was all in good fun.
We started up the road, windows down, with the music cranked.
I could see Jill giggling as she squirmed in Eric's lap but I was more focused on Tina's cute nipples pushing against the fabric of her small top.
The way Tina touched my leg as she talked to me was setting me on fire. I was struggling to keep my cock under control as we drove.
Once we arrived, we grabbed the tubes and I poured everyone a margarita from the batch I made ahead of time.
The sun was hot and the water was amazing. We floated and drank and talked about old times. We laughed that we had both showed up with same tubes, double seated with a cooler in the center.
When we hit the first deep section we all spilled out of our tubes for a swim. I could barely touch and it was way over the girl's heads. I found a rock to anchor my foot and held on to our tube and cracked a beer. Eric did the same as the girls swam back and forth.
I felt a pair of soft hands around my waist but they weren't Jill's. Tina had come up behind me to hold on since she couldn't touch. Jill had done the same to Eric.
I slipped Tina in front of me so she could hang on to the tube while she opened a beer. Since she couldn't touch she wrapped her legs backwards around me to hang on. Doing this caused her tight ass to push directly against my cock. I was instantly hard and there was no fighting it!
My cock pressed tightly up against the crack of her ass. Instead of pulling away Tina squeezed her legs and pulled me tighter. I couldn't believe it! Aside from all the harmless flirting over the years, we'd never been in a position like this.
I looked over afraid that Jill would be staring right at us. She wasn't, she was also in front of Eric sipping her beer and looked like she was getting the same treatment.
Just then Tina tried to pull herself up and set her beer in the float. When she did it caused her pussy to ride up my hard cock. I could feel it separate her lips through her thin bikini. I could actually feel the heat coming off of her sex! She slid all the way up my cock until the head of my cock was pushing directly against her opening. For a split second I felt the head of my cock, still covered by my trunks, drive her bikini into her tight pussy.
For that brief second in time, the very tip of my cock had breached her opening. Tina gasped and slid back down my cock. She gave it a quick squeeze with her hand and swam away.
Jill was on her way back to our float, grinning. I looked over as Eric was climbing into his tube and I could clearly see he had a full erection. His cock was straining against his trunks as he tried to keep his back to Tina to conceal his problem.
