This story is bi. There are also made-up characters, use your imagination. You have been warned.
Gabe thought he was the greatest when he was invited to Jo's family vacation. Sure he was already engaged to her and intended to have a wedding at some point in the next 6 months, but he felt getting to go to their family vacation meant he was really part of the family.
A beach was where they were going to, a beach that Jo often talked about actually. As far as Gabe could tell it was private and maybe it was rented or something? Gabe wasn't entirely sure. Gabe hadn't actually been to a private beach before and he actually didn't like the idea very much, he wanted to show off his muscles and look at women, although he had to make it not obvious because he was with Jo when he was at beaches now.
While he was packing, he packed several different swim trunks just in case.
"You're not going to need that many." Jo said.
"I might, you never know what might happen." Gabe said.
"You're really not going to need that many." Jo said.
Gabe just rolled his eyes and kept them in his pack, but he kept thinking about what she said as they boarded the plane and thought about how he didn't actually see Jo pack any bikinis at all, but he wasn't paying that much attention to the clothes she was packing, more focused on the ones she was wearing and getting them off of her.
He didn't even have to pay for anything. No fuel costs or food costs, he really felt like they really liked him.
Jo had three brothers, two older and one younger, all of which were in relationships as well, so at least he had three other women to look at, but obviously with Jo around and their husbands around he had to be very careful about looking at them.
Jo insisted on driving since she knew where she was going. And Gabe was fine with letting her drive to there. He thought about potentially asking her about what it meant when she said he won't need that many but he didn't, it wasn't worth thinking about at the time.
At least he thought it wasn't. But now he would find out it was.
They got onto the beach and he thought they were all going to have a look, which he found strange because that family had probably been there many times, but then maybe it was for him?
Then they started stripping, he thought for a second they were already wearing their bikinis and swim shorts already, but he swore that they weren't already, at least the women weren't, he would've noticed it if they were actually considering he tried to get a good look at them.
But no, they weren't. They got naked. Including Jo.
"You got a problem?" He was asked by one of Jo's brothers.
"You gay?" He was asked by another.
"You didn't tell him?" Jo's father asked.
"I kind of forgot." Jo said.
"Clothing's optional." One of the wives said.
"You're not scared are you?" He asked. He was a little bit. Because he was looking at dicks, even thought he didn't want to, or at least thought he didn't want to, and they seemed to be a bit bigger than he was. But then again they might just be show-ers and not growers.
So he did it, he got naked with them and within a few minutes of swimming he was feeling a bit more confident. After a while he didn't even realize he was naked.
It wasn't until he got onto the beach after swimming for a while. He sat on his towel and got a bit of an erection. Then he got fully erect. He hid it and went down. But then he saw that her brothers got erect too while sitting on the beach. He didn't mean to look. But he did. And they were so much bigger than him.
He got erect. From looking at their erections. They seemed to be maintaining their erection a lot longer than he ever did. They just seemed constantly erect and fully erect. And they were so much bigger! He couldn't let that go!
He stayed erect. He was seen having an erection.
"That's it?" Jo's father said. He kind of pushed his erection towards Gabe. Gabe looked and then took his eyes off of it. Jo's father shook his head.
He was absolutely outsized by them all. They had to be 7 inches at the smallest. Her younger brother seemed to have the biggest cock, and the thickest Gabe was just bigger than 5 inches, he was very outsized here. How did they even fit those into women?
Being smaller than all the guys actually turned him on, strangely enough. He was now having an erection constantly much like the others, but not as big.
"Good thing we have our own room." Jo said to him. He hoped that she had no suspicions about why he was erect.
They pretty much spent the whole day swimming and eating food they brought. They would be driving up and eating at restaurants every day. So that would be good.
That night they all went inside and he absolutely needed to fuck Jo.
He was already naked so their wasn't much they needed to take off, but he eagerly dived into Jo's pussy and started licking her pussy with intensity that Jo hadn't felt in a long time, and Gabe really hoped that she didn't notice that he so much more into it right now and wouldn't question it, because he was very much embarrassed that the reason he was so horny was because of other dicks. But sometimes competition made men more horny even thought her siblings and father weren't actually competition.
He fucked her so hard too. He was completely into it. He absolutely needed to cum. Jo kissed him and didn't ask, he was fucking her quite well, she enjoyed that he seemed to be paying attention to her pleasure too, making her he touched her breasts and tried rubbing her too while he was fucking her hard. His cock was really making her feel good too, like he was slightly more erect than he was usually.
He was definitely hornier than usual. Which she just assumed was because he liked seeing her naked a lot, she had no suspicions at all about that he was actually turned on about cocks.
He came hard too, blowing a heavy load into her pussy, it was a good thing she was on birth control because if he was going to be blowing loads like this every single time he fucked her he would get her pregnant quickly for sure, and he wasn't sure if he was ready for that. If he felt like this every time he would be blowing these loads. He seriously hoped Jo didn't ask him why because if she did he'd just stutter.
While Gabe finished off Jo he got erect again, but he didn't say anything. He waited a bit until Jo went to sleep and went out to the beach to stroke himself. Just quickly, no one would notice, right?
