Like many of the epic holds I've witnessed, this one started without me even thinking about it. Our family had caught Pokemon Fever, so I had planned an outing to go catch some. It's a marvelous idea and has gotten countless people out walking around. It is particularly helpful because me and my wife have been trying to get active again, but it's difficult with small children (ages 7-11) who fight you about going on long walks. There's a few good parks in my hometown, but we wanted to try something different for the weekend since it was finally out of the high 90's. I planned out a few places to go in a large city about an hour away. We left about 10:15, with my wife, Jenna, peeing about 15 minutes prior. On the way out, we dropped off our oldest with the grandparents since she wasn't feeling well, then stopped at a gas station to grab some drinks. We already had a water bottle each in the car, and I got 3 gatorates - one each for me and Jenna, and another for the 2 kids to share. Jenna grabbed a Dr. Pepper as well. We finally made it to the highway by 11, and made it to the first park about noon. Despite it being much cooler than even a week earlier, it was still a little hot for the little ones in direct sun - I think we made it for about 15 minutes before they'd had enough. Back in the car, I made sure everyone was drinking fluids to stay hydrated on our way to another nearby park. Same drill as before, but we couldn't get our son to move at all. By this point it was around 1 and everyone was hungry, so we headed to one of the malls in town for the highlight of the trip - a store with nothing but pokemon items. Since we'd all been sweating, I made sure everyone finished up their drinks. Arriving at the mall around 1:30, we went straight to the food court and all got lunch. I took the kids to Chick-fil-a, and Jenna went to Panda Express for us, coming back with the food and a soda for us to share. When we all finished, our son (who inherited his mother's bladder) needed to pee, so I took him to the bathroom and our daughter followed as well. Coming out, my daugher was walking out of the bathroom, but I didn't see Jenna. I waited for my wife before I got a text that she was on the other end of the food court. Surprised, I asked her if she needed to pee. "No, not really" was her answer. Things just got interesting Up until this point, I hadn't even thought about her bladder. We had all been sweating so her normal 1-2 hour pee schedule was lengthened. Now, though, she had skipped what turned out to be her last good opportunity to pee. I could tell she was thinking about it before we walked off, but she hates crowds and avoids them if possible. If she really needed to pee she would have gone, but I think she was planning on finding another bathroom elsewhere. It was around 2:30, about 4 1/2 hours since her last pee. She had been drinking enough fluids to hydrate her from being outdoors, and she was sipping our soda, so it was going to start hitting her soon if it hadn't already. We made our way downstairs to the Pokemon store and the kid's eye's lit up! They were in heaven and were running around looking at everything. We finally got them corralled up and focusing on things, so I told them they could pick $25 worth of stuff each. During all of this, Jenna was looking very antsy and finally said "There's too many people here, I'll wait for you outside". It's true it was busy, but not enough to where she would normally have to leave. When she has to pee she gets very antsy, so her bladder was obviously getting to her at this point. I finally got the kids rounded up, but it was over 45 minutes spent in the store. Now that we were done in the mall, it was time to head back to the car and go to the last stop - a heavily wooded park that the kids would actually be able to enjoy. As we made our way back to the car, I could see Jenna scouting for a bathroom, but there weren't any between us and the car. When we finally loaded up, it was after 3:30. Getting in the car, she immediately got into her "I need to pee" position: she has her legs firmly together and sits slightly sideways, which allows her to pull her knees up further to offer a little relief. It's usually one of my first signs that she needs to pee but not yet desperate. Thanks to the size of her bladder, though, it doesn't take long to get from "needing to pee" to "getting desperate". Normally it's less than 30 minutes, less if she's hydrated, and it had already been over that. I think my wife was expecting another short trip to the next park where she would hop out of the car and go pee in the nearby restroom, so she didn't say anything on the way out of the mall. Little did she know it was at least 30 minutes away, and probably more. My dick got hard just thinking about it. After about 10 minutes, our daughter asked how long it was going to be so I made a smart-ass remark about it being 15 hours. Not long after, though, Jenna said that she could really use a bathroom and asked how long it would actually be. I told her 20-30 minutes, and I swear I heard a groan from Jenna. I never want to force her to hold it so I asked if she wanted me to stop, but said she could make it to the park. As she said this, she moved from just having her legs clamped together to crossing them tightly. I was driving so I couldn't get a real good look, but I could definitely see her squeezing her thighs together a few times after she crossed them. I had been hard since we got in the car from thinking about her waiting; it had been getting uncomfortable but I was trying not to bring attention to my predicament. After hearing and seeing that, though, I didn't have a choice. I was fully erect and straining against my boxers to the point it almost hurt. Not caring if she saw anymore, I rearranged my pants. It took a lot longer than normal to get it into a location that was decent, but she was so preoccupied with her need to pee that she didn't notice. Unfortunately for her, my estimate ended up being optimistic thanks to traffic. As we were about to exit the highway at 4:15 (I was keeping a close watch on the time at this point), I asked Jenna if she wanted anything else to drink before we hit the trail. She snapped back that not another drop of liquid was entering her body before she peed. As we exited, Jenna said "I need to find a bathroom fast, I hope it's close." Music to my ears! It took another 5+ minutes to get to the entrance to the park. It was a long park, so we had to drive further before we finally saw cars. The park was very busy, and it took a little while to make it to the hiking trails. I could tell parking was packed, so instead of circling around wasting time looking for a spot I pulled in the first place I saw. She jumped out and started looking around for anything resembling a bathroom, but saw nothing. At that moment my son announced that he needed to pee. He found a tree right next to the car, and walked up to it to pee. He is a bit shy, though, so nothing happened. After a little while of Jenna impatiently waiting, he asked her to stand next to him cover him. Not longer after, his stream finally started. As soon as she heard the first splash, Jenna crossed her legs and bent over slightly for a few seconds, fighting a quick smasm as her bladder reacted to being so close to someone else's bladder that was able to release itself. As she regained her composure, I could see a look of a envy mixed with hatred before she muttered "I would do anything for that right now". When he finished, we continued down the trail, Jenna power walking to the first thing that looked man-made. It was obviously a sign, so she went to the next structure, which looked like a bathroom. I saw a group of college girls running up to it ahead of Jenna, also clearly looking for a toilet. Meanwhile, I stopped and looked at the sign, and didn't see a single marking for a bathroom. It looked like this park was just serviced by port-a-pottys, which my wife detests and will only use in a true emergency. Given the circumstances she would have definitely used one, but there weren't even any of those nearby. Seeing that it was hopeless finding a bathroom I looked up to say something to Jenna. Before I could open my mouth, the first girl stopped, yelling "that's not even a fucking bathroom!" Hearing this, Jenna stopped dead in her tracks. A second girl said "Its just a pool. Now what do I do?" My already hard cock got even harder at this point. Jenna hurried back to join me at the sign, asking me where the closest bathroom was but I honestly told her I didn't see anything on the map. Just then, I heard one of the girls exclaim "What are you doing!" as we heard water splashing. We both looked over and the first girl had squatted down, peeing forcefully on the pavement. Jenna gasped, crossing her legs again, keeping her bladder from emptying in sympathy with the girl's nearby. Thankfully both kids were engrossed in their game and missed the spectacle, but that didn't help Jenna at all. I was getting concerned for her, and asked her what she wanted to do. Her hand were clenched tightly in a fist She sighed loudly, then said "Well, I guess I'll just hold it. Let's go hiking guys." She gave her muscles another long squeeze, then straightened up and proceeded to head down towards a trail. We had to talk by the girls, one of them bent over moaning and the other still emptying her poor bladder. As we passed by, Jenna had to stop briefly to maintain control before swiftly moving past. After all of this, my dick was so hard it was actually painful. I'm about 8" long with some girth, which is great in the bedroom but horrible in situations like this. There was a VERY obvious bulge in my pants, so I had to find a way to make it to where it wasn't too obvious I had a raging hard-on in the middle of a family park. I jammed my hand in my pocket, holding it so only my hand was seen. It was still quite obvious, but at least not to the point where a kid might notice. The first trail we reached was paved and obviously heavily used. She has no problem peeing outside, but won't do it if anyone might see her so she kept walking. Since I had parked at the first place I found, it was a decent walk to the end of the parking lot where the rest of the trails apparently started. All the while, Jenna kept trying to speed walk, but the kids were dragging behind, forcing her to slow down. After a several minute walk, we finally reached the trailheads at 4:30. Picking the first trail, we walked down it for about 5 minutes, Jenna scouting for a place to squat. She stopped, looking at a spot she might be able to use but as she was reaching to pull her pants down, a car drove past - this backed right up to a road! Without saying anything, Jenna turned around, back-tracking to the parking lot to find another path. It was 4:45 when we made it back to the trailhead. The path she found was away from roads, but also looked like a commonly used path by mountain bikers. The problem is that hikers take a while to get to you, giving you time to finish up, but you have about 5 seconds notice with a biker. On top of that, all of the trails had a very thick cedar forest on both sides, so it was impossible for her to get far off the path. As soon as we were on the path, she immediately asked me if I thought it was safe for her to pee there. My response was "I think? Maybe?" She looked at me and said "That didn't sound very convincing...." I told her that it looked like a mountain bike trail and that they could come up very fast. Seeing her reaction of near panic, I told her that I would keep watch while she peed. She didn't like that at all, shooting back "What, am I supposed to just stop peeing? You know I can't do that - it hurts too much" to which I shrugged my shoulders and told her that if she didn't like that she'd just have to hold on. She chose the "holding on" option so we continued on this trail. Jenna desperately hoping for a side trail she could squat in, but there was nothing. A few minutes later, she grabbed the top of her pants and stopped to look at a possible spot, dancing slightly in place before she decided it wouldn't work and moved on. Finally, after 10 minutes of this, she stopped, telling me she absolutely had to pee. I told her that was fine, as long as she was OK with a mountain biker coming up. She huffed loudly then continued on the trail. Another few minutes and she yelled "Fuck it! I have to pee right now". She ran to a tiny clearing that was only a few feet off the trail and it happened to fast it caught me off guard. I wasn't able to listen for anything, so as she was pulling down her pants, dropping into a squat, I yelled at her "Hold On! I need to make sure it's clear!". She bolted back up and practically screamed "What do you mean?!?!". As she did this, she yanked her pants back up and went into her "I have to pee" pose - slightly bent over, with one knee raised up and crossed over putting as much pressure on her pee-hole as possible. Incidentally, this is the same pose she gets when she is super turned-on as it also puts pressure on her clit and will give her a quick orgasm to take the edge off. However, on this occasion, she was doing it to an extreme that I had never seen before. It was incredible. Still looking down the trail, I told her "I just need to make sure there isn't anyone coming. I think its clear - " This was all she needed, and before I could add that I needed to make sure, she had her pants below her knees and was dropping into a squat. Before she had started peeing, though, I heard the unmistakable sound of a bike. Just as I heard her pee splattering on the ground, I yelled at her "Stop! I hear someone!" She shouted "What?!" but I again told her I heard someone. Despite my claim of keeping watch, my eyes were now glued on her. She yanked her pants back up, or at least attempted to. I was amazed she didn't hold herself, but apparently she was too worried about someone seeing her so cover took priority over holding. One hand was on the side of her pants opposite the trail, which had mostly cleared her hip. The other was in the front of her pants, pulling it to cover her crotch, but this left most of her ass wide open. Time froze, the image before me permanently etched in my mind. She had her pants partly pulled up, with her left buttcheek totally exposed. Her left leg was bent upwards, further showcasing her naked rear, her knee pulled all the way across her stomach to maximize the pressure on her peehole. I was speechless. I heard her grunt loudly, obviously straining massively to clench off the jet of urine erupting from her body. A couple seconds later, after she caught her breath, she hissed back "Ohmyfuckinggod I just peed in my pants!" Despite her previous claim that she couldn't stop once she started, she had managed to clamp off the flow. However, it had obviously taken a huge toll on her. Her hands were clenched into a fist, her legs quivering from the effort of holding back her bladder any longer. All told, she she couldn't have gotten more than 2-3 seconds of relief, and now it was infinitely worse for her because she had forced her tortured muscles to cut off the relief she so desperately needed. I was still awestruck as this was something out of my wildest fantasies, nearly gaping open-mouthed. I was snapped out of it, though, by her pleading through gritted teeth "Is it clear?!" My answer of "I think so" didn't please her at all, however. I looked both ways on the trail before I looked back at her, finding her practically bouncing in that position. The devil in me wanted to drag this on for as long as possible, but I had pity and told her "Just pee already!" As she shook her head emphatically, all I got out of her was "No! Someone is coming!" Trying to do anything to get her to finally go, I yelled back that I actually heard a car and that it was totally clear. After another several more seconds of this, she finally gave in. Even as she was yanking her pants down, she had already started peeing. She had previously been turned some to the side, but when she crouched the second time she was facing directly towards me. Her pants were around her knees, which were splayed as widely as possible, her feet far apart from each other to avoid any collateral damage. I had a clear view of her gorgeous pussy, perfectly framed by her legs, unable to remove my gaze from the torrent of pee spraying out from between her legs. Over the next 5 seconds, it increased in intensity. It may have been my imagination, but I swear I could see her lifting up from the force. 20 seconds in, the stream lessened to a normal flow as the gasped, yelled "OH MY GOD why won't you finish!?!?" then went back to gushing for another 15+ seconds. All told, it was close to 40 seconds of a VERY powerful stream. It wasn't the longest pee I had seen from her, but it was definitely the most powerful. I was in awe. The second she stopped, she yanked her pants back up, taking several seconds to get them rearranged, and headed straight back towards the car. The kids were ready to get back as well, and we managed to speed them up with a bribe of ice cream when we got home. I was still in shock, and wasn't sure what to say on the way back. What is even more amazing than just encounter was what it led too. Once we were up to speed on the highway, and the kids had crashed out from the walking, I brought up the topic of her desperation. She is very aware of my liking it when she has to pee, and periodically indulges me, but I don't think she ever understood the true extent of it. This was a perfect way to start the discussion. Normally I'm shy about this, even with someone I will tell anything too, but I couldn't let this pass. I mentioned that I was sorry she couldn't find a place to pee, but that it was a massive turn-on for me. She immediately looked down at my pants, seeing the bulge in my pants, and said "I can see that!" I looked at her (well, glanced because I was driving) and told her "You have no idea. That was possibly the most turned on I have ever been. When we realized there wasn't a place for you to pee and you kept going, by cock might as well have been a steel rod. It was so hard it hurt. It was so incredibly hot." She looked me and told me she sorry I had to go through that and reached over to stroke it, the she let out a little "Oh!" when she felt how hard it stil was. I just told her "See, I told you it turned me on! Its been 15 minutes since you peed, so you can only imagine what it was like." She paused, thinking, before she leaned over and whispered "Well, we'll have to make sure he feels better later" as she stroked my still swollen member. I told her "I hope so, because it's getting pretty bad! You know when I tease you and don't let you cum for over an hour? You know how your clit feels? Image waiting all day." She got a concerned look and cooed "Oh, that IS bad! If the kids are still going to their grandparents tonight, then I will definitely make it up to you."
