Chapter 5.1: Fun While Exercising in Public.

With the arrival of spring and better weather, I had begun to run regularly again. Every weekday, I ran to a large public park, about a kilometer away from home, did a full loop around the park and ran back home. I did it as soon as I came back from work. Since Belle finished working a bit later than I did, by the time I came back from my run, she would have just come back home. She often joined me under the shower, sometimes just to wash my back, but more often with naughtier intents.

I don't know if discovering our own exhibitionism had made me more aware, or if I'd started to read sexual undertones in innocent acts, but I seemed to notice girls exposing themselves much more often during my runs. A girl sitting on a bench in a skirt with her legs a bit too spread apart, the hem fluttering in the wind without her ever trying to fix it, here. Another who 'accidentally' lifted her t-shirt while removing her sweater, letting her boobs peak out for a second, there. It wasn't every day, but I came home having seen something along those lines more often than not.

Regardless of the reason, I couldn't help but see. I told Belle about all these events when I came back home. I did it mostly because not sharing would have felt like lying to her by omission. But I knew she liked these little anecdotes, because she pictured herself doing so, and sometimes it gave her ideas for future light exhibitions. She'd never been jealous about me looking at other girls anyway. Even before we'd started letting our kinkier side free, she would sometimes discretely point to me a girl with nice boobs and a deep cleavage, or one with a nice butt molded in her clothes, walking by.

As she'd said more than once to other girls when they seemed surprised she did not care, "There's no hurt in looking at a beautiful thing. And I don't have any issue with him looking at the menu of other restaurants, as long as he doesn't forget he's contracted to eat at a specific one."

A Friday evening, soon after Mark left, as I was showering alone for once, Belle's confession that she would be missing having other spectators than myself gave me an idea. As soon as I was done, I went to the kitchen, where she was loading the dishwasher. When she saw me walk in naked, she couldn't keep her gaze from falling down to my cock swinging freely as I walked.

"Honey? I thought about what you told me after Mark moved out, and I may have an idea." She raised an eyebrow, wondering if I was about to suggest something mundane or much wilder, I explained myself. "What if, starting Monday, instead of going on my run before you come back from work, I wait for you, we go running together, and while at the park you did your routine there? I'm sure you'd attract the attention even with your yoga suit on."

She thought about it for a few seconds. "Why not? The change of setting could be nice..."

"And, who knows? After a while, you might end up with a bunch of loyal spectators!" I half-joked.

She giggled, "But I'm not gonna do my routine naked in the park. Don't start dreaming!"

I laughed, "And there goes my grand plans..."

I went to the PC and, after a bit of browsing, ordered a new sports outfit for her. I found a really sexy black one, mini shorts with large bands of sheer lace down the sides and their assorted sports bra, the band of lace going straight down the middle front. I could not wait to see Belle's rack in this one.

As I was about to order, something else caught my eyes, a black sports tank top, with a deep neckline and very large armholes. I immediately pictured Belle wearing one without a bra, offering magnificent sideboob views... And, cherry on top, it was printed with the number 69 in grey on the front. I chuckled and added it to my order.

We went on our first run together the next Monday. It was a bit chilly so Belle had put a black zip-up hoodie over her usual outfit. I could not help but notice every guy who turned around to check her bubble butt as we ran past them. Belle seemed oblivious to the effect she had on them. After about fifteen minutes, as we started to heat up, she'd unzipped her hoodie. I could now see her tits bounce up and down with each stride. And the number of men who checked her out increased exponentially. She started to notice, and the way she ran changed slightly as she tried to expose her assets as much as she could.

As we reached the entrance of the park, Belle stopped to remove the hoodie altogether, handing it to me to put in the backpack I'd taken to carry her yoga mat and our water bottles. The skin of her midriff and her back were now exposed, glistening with sweat. As far as I was concerned, seeing her sweaty made her even sexier, I couldn't help but link it in my mind with images of her sweaty body after sex on hot summer days.

As we ran around the park to the spot I'd picked for her to do her routine, her bouncing boobs even attracted the attention of some women now, some of them green with envy, others with a more lustful glint in their eyes. I showed her the spot, a patch of grassy area along the main outward path of the park with trees and bushes on three sides. Along the opposite side of the path was a bench, from which I would be able to watch her do her routine. We sat on the bench, I fished her water bottle out of my backpack, handed it to her, and while she hydrated herself, unpacked the yoga mat.

Belle walked to the middle of the grass, unrolled her mat and started stretching. She'd barely started her first set of exercises, her boobs bouncing as she performed jacks, when a fifty-something-looking guy asked me if I minded if he sat down on the bench. I removed my backpack, making room for him. We both watched Belle go through her usual routine, with the experience she now had with having spectators, she always made sure to offer the best angle of view for each exercise.

While she was facing away from us, doing her squats, holding the position a few seconds each time she was in the chair position, her ass stretching the fabric of her pants, I saw the guy re-adjust his crotch a few times. Belle seemed to enjoy the attention. She even groped her own ass, pretending to check the effect of the exercise on her glutes. I saw a bead of sweat run down her spine, and the images of her sweaty body post-coital flashed in my head once again.

By the time she'd turned around and started doing push-ups, her cleavage now the main focus point, the guy had placed the shopping bag he'd been holding on his knees, most likely to hide his bulge. I grinned when I noticed and returned my gaze to Belle, who caught my eyes, grinning too. She started to force herself to go further down than usual during her push-up, slightly squishing her boobs against the mat and causing them to bounce a little when she pushed herself up. She did less push-ups than usual, but the enhanced visuals were worth it.

When she moved to crunches, groin towards us, I noticed something which had never happened before. Her yoga pants were outlining the shape of her pussy, basically giving her a camel-toe. Did she pull her pants up on purpose, or was it a lucky accident? I never thought about asking her. The guy had noticed too. The tip of his tongue licked the corner of his lips, he was watering at the mouth, probably imagining eating Belle's pussy.

Belle had been doing advanced crunches for a while now, starting in a sitting position, arms crossed over her chest, her feet slightly off the ground, basically balancing herself on her butt. Then she would extend her legs forward as she lowered her torso until it was an inch off the ground before coming back to her original position, her butt remaining the only part in contact with the ground all along.

While coming back up, to maintain lateral balance and avoid falling to one side or the other, she had to slightly spread her knees each time. This offered a clear view of her crotch for about two seconds each time. By the fourth crunch she did, I heard the guy let out a loud gulp, and couldn't help but smile. If this was having this effect on him, her yoga routine, coming up next, would crush him, particularly the cat-cow pose.

I never really bothered with remembering the names of each pose which constituted Belle's yoga routine. But there were a few very sexy moves in there. I know the first move, which she uses to transition from the crunches to her routine, is called 'the Butterfly', sitting with legs spread and feet together. Then she would switch to 'the Garland', legs spread, feet on the ground, with hands joined as if in prayer. These two I remember because when she did the routine naked these last months, her pussy was on full display, spreading open by itself.

And even with her yoga pants on, the view remained very arousing. The guy was on the edge of the bench, not missing any of it. Belle stood up and slowly cycled through the five or six standing moves of her routine. These few moves constituted what I called the 'soft belly' of her routine. While Belle's body was always nice to watch, these poses didn't really enhance any part of it for the viewer. They displayed her flexibility, however, which, the first time you witnessed it, was sure to make you imagine the possibilities in bed. The guy was staring all along.

She continued the sequence, now moving through the series of poses which culminated with the cat-cow pose. As she finally reached that point, her ass facing us on all fours, the guy gulped again. I stifled a chuckle. At that point, the guy was so entranced he had completely forgotten I was sitting right besides him. Belle went through the last few moves of her routine, stood up and without turning around, started to roll her mat, displaying her ass one last time. The guy took it as his cue to stand up and walk away.

Had he waited a bit longer, he would have had a nice surprise, because at some point during the few last moves, most likely during the transition to the pose called 'the Cobra', which involved Belle dragging her tits across her mat, one of her nipples had escaped the confines of her sports bra. Too bad for him, if he'd been less in a hurry to leave, too flustered to dare risking she'd talk to him once she was done, he'd have gotten this last treat. I pointed at Belle's little wardrobe incident. She grinned, corrected it and merely asked how long it had been like that, unfazed.

"Just happened before you stood up, I'm the only one who saw."

But a rustle in the bushes let me think it might not be the case. I looked around, but saw no one.

Belle drank a bit of water while I placed the mat back into the backpack, I packed the bottle once she was done. And we resumed running, completing the lap around the park. As we reached the entrance, I asked her if she wanted to go back the way we came or if she felt okay going through a slightly longer route, along the canal. I didn't mind the extra distance myself, since I made a break on the bench. She agreed to go the longer way.

As we were running along the canal, Belle commented on how calmer and less frequented this way was. I misunderstood her meaning.

"If you want we can run both ways through here next time..."

She giggled. "Look at me, silly!"

I turned my head. She'd lifted her top and her boobs were swinging around freely with each stride.

"Calmer it is, and the view's much better too!"

"Not gonna last long though, running without any support quickly hurts!"

As we passed under a bridge, I told her to stop. I grabbed my phone from the backpack and took a few pics of her exposing her tits along the canal. She then put her bra back in place, and we ran back home.

The package with her new outfits came in the next day. Belle tried on the black outfit, the lace down the middle of the bra made her cleavage simply breathtaking, and her butt greatly enhanced these shorts, they looked even better on her than they had on the model in my opinion. She checked herself in the mirror.

"A bit risqué huh? Well, I will wear it on our runs, but it'll have to wait till it gets hotter outside..."

"While you're wearing this, it'll always be 'hotter', wherever you are."

She took the bra off and threw it at me, giggling. "You shameless flirt!"

She looked at the tank top, and giggled when she read the front print. She tried it on and looked at herself sideways in the mirror.

"I think I know exactly why you picked this one. But I'm not going to run with this, my boobs would hurt after merely fifty strides."

I smiled, "I knew that, but I thought that, maybe, we could walk to the park once in a while... I wouldn't mind seeing you do your routine wearing this."

Before I could finish my sentence, she'd started doing a few of her usual yoga poses in front of the mirror, her nipples becoming visible quite often. She grinned.

"Well, maybe... If I get those 'loyal spectators' you promised, I might reward them by wearing this."

I mockingly pouted, pretending to be offended she wouldn't do it just for me. She removed the tank top and playfully threw it in my face.

"Of course, I'll do it even if it's just for you," she said, giggling.

The next few days went almost the same way as the first. Most of the times, Belle's routine attracted a few spectators, who watched in silence and left as soon as she was done. On the way back, we went along the canal, she flashed me under the bridge, sometimes her boobs, others her ass. I took a few pictures of her exposing her ass the first time she did. The next times she flashed me, I just kissed her on the exposed part before we resumed our run.

There was a concrete bench under the bridge, and one day I asked her to get naked and lie in a sexy pose on the bench. She agreed, I took a few pictures, she put her outfit back on, and we ran back home. Another time, as we reached the bench under the bridge, Belle walked up to it, bent over and pulled her pants and thong down, revealing that she'd been running and doing her routine while wearing her buttplug. I took a few pics.

"I wanted to see if it would feel good, but it's actually quite a nuisance", she said before pulling it out, pulling her pants up, rolling the buttplug in a tissue and placing it in the backpack.

"Geisha balls might feel better..."

"Maybe, but are we really gonna buy some just to check?"

I shrugged. "Even if the test failed, I'm sure we'd find some other use for them. I'm pretty sure it would not be a waste of money..."

One day, Belle called me to say she would have to stay at work for another hour, and suggested I went without her. I told her I'd wait for her. She came back home an hour and a half later than usual. We started our run. The crowd in the park was slightly different at that hour, and I had to firmly ask a group of rowdy youngsters to get lost, because they kept cat-calling on Belle quite rudely during her routine, making her feel uneasy.

As we arrived under the bridge along the canal, Belle flashed me as usual. But a sudden cheer surprised us. We'd gotten so used to the place being deserted these last few days, that we hadn't checked across the canal. On the other side sat two homeless guys, who probably slept there at night. They had beers in their hands and were waving at Belle, who in her surprise had kept her top lifted, still flashing them now. She pulled it down, eliciting a moan of disappointment from them.

Belle turned towards me.

"It's been a while since we got an occasion to show off, since they're on the other side of the canal, they can't reach us faster than we can run away... Do you feel like giving them a show together?"

I shrugged. "If you feel like it, and if you give me enough of a show to give me a hard-on, then yes..."

She giggled, but hesitated. I could feel she was having second thoughts and felt a bit uneasy exposing herself to homeless guys. I understood her dilemma and thought a slight push might help her take a decision.

"Do you really care whose eyes are watching you? Or is it just being watched that counts?"

She made up her mind, turned around, spread her legs a bit and pulling down both her pants and thong at the same time, bent at the waist. She flashed them her ass and pussy, slowly swaying her hips. The guys cheered loudly at the sight. I feared, if they kept going like that, they'd end up attracting attention.

I shouted. "You shut up or it stops!"

They both lifted an apologetic hand, signaling they'd understood. One of them mimicked locking his mouth with a key before throwing it in the canal. The childishness of this gesture made me chuckle.

Hearing me asserting control of the situation must have turned Belle on, because, by the time I turned my attention back to her, she was caressing her pussy. I threw a glance towards the guys again, they were gawking, entranced by Belle's lewd display. I heard her moan, and one of the guys elbowed his friend. I immediately thought Belle must have slipped a finger or two up her vagina and turned my head to enjoy the show.

In the short time it took me to turn my head, she'd stopped. She was standing up. She turned around, crossed her arms over her breasts, grabbing at the sides of her sports bra, and lifted it completely over her head, removing it. The puppies bounced as they were suddenly freed again from their prison of fabric. A sight I will never grow tired of. She was now facing them almost completely naked, her yoga pants at knee level. Spreading her arms out, the shook her boobs. One of the guys cheered, but his buddy elbowed him in the shoulder while shout-whispering.

"Shut the fuck up, you dumbass! I wanna see how far she'll go. If they stop because of you, I'll beat your stupid ass."

Belle played with her boobs for a bit, massaging them, pinching on each nipple. Then she pinched hard on both at the same time and lifted the whole weight of her boobs by tugging on her nipples. She closed her eyes and bit her bottom lip, clearly enjoying the pain she was inflicting on herself. She let go of both at the same time, causing her boobs to bounce once again. I did not notice it at that moment, but it was the first time Belle had felt free enough to really demonstrate her masochistic tendencies in public.

Being done with the teasing phase, Belle sensually beckoned me to approach. I stepped closer. She grabbed my hands, placed them on her boobs, and kissed me, her hungry tongue meeting mine. She moved her head back slightly so our tongues now met outside of our mouths. I felt her hand slide inside my shorts and briefs, caressing my already erect dick. She stopped kissing and turning her body in the direction of our audience, crouched down. I heard whispers coming from the other side of the canal, but didn't catch any word.

Belle started to masturbate again with one hand while she tugged on my shorts and briefs at the same time with the other, causing my cock to pop out suddenly, it slapped her on the cheek. She giggled. The next instant, she turned her head sideways to face my cock, wolfed down on my glans and started blowing me off hard. She used her free hand to jerk my shaft while she sucked on the tip, her tongue twirling around my glans, to begin with. But she slowly took more and more within her mouth and eventually had to let go with her hand to allow even more of my shaft to penetrate her mouth.

She was sucking as fast as she could while moving her mouth as much as possible along the length of my cock. Moving back until her lips just went past the back edge of my glans before swallowing as much of my dick again as her mouth would allow, bringing her lips just two inches short of the base of my shaft. Almost my whole length was now glistening with her saliva, and she let out loud slurping sounds as she drooled all over my manhood. It was the sloppiest blowjob she'd given me in a while, and we were both enjoying it.

The whispers on the other side of the canal had redoubled, I threw a glance that way and saw that the two guys had sat back on the bench on their side, covered their mid-section with what I guessed were filthy sleeping bags and were clearly jerking off under them. The thought that Belle would not have to see their dirty dicks was a relief. I doubted she would throw a glance their way anyway. She clearly seemed to pay no mind to what her audience was doing, focusing only on offering the lewdest show she could.

In my mind, I imagined the show we were offering from their point of view. Belle crouched down, legs spread as much as she could, the pink of her insides probably visible. I could picture her fingers frantically flicking her clit while she swallowed as much of my cock as she could. Being homeless, they did not have the easy access to porn which most people take for granted these days. So what they witnessed right now must be even more of a turn-on for them than it had been for any of our previous spectators.

Belle kept going, moaning on my cock as she pleasured herself at the same time. I started to hear the faint sound of flesh slapping flesh echo under the bridge, I looked down and saw that Belle was now fingering her pussy hard and fast. The clapping sound came from the palm of her hand hitting her pubis which each move. Seeing her pleasuring herself so shamelessly in front of their eyes must have been the last straw for our audience, because I heard them both grunt quite loudly in quick succession, soon after she'd started.

She moaned harder and harder around my cock, never stopping her wide back and forth along its length. With a strange gurgling sound, Belle came. I looked at her and saw that, while cumming, she'd deepthroated me by accident, managing it for the first time. I could see the surprise in her eyes, as she realised her lips where now around the very base of my shaft. But she did not move back, she'd just stopped moving, as if she did not know what to do next. How to deal with the fleshy rod which had intruded in her throat.

I was starting to move back to free her throat from the invasion by my cock, but felt the hand she'd initially used to jerk me off grab my buttock, squeezing it hard, keeping me in place. I looked down at her again, and she was staring back at me. If her eyes were teary, I saw something in them which I could only describe as triumph. She swallowed a few times with my cock still fully down her throat, then very slowly moved her head back an inch before immediately trying to push my cock back down her throat. She repeated the motion a few times, faster each time.

But at some point, her gag reflex got the best of her, and she released my cock, gasping, taking a few deep breaths. The homeless guys started to clap, quietly. I was baffled by their reaction for a second. But then I connected the dots and understood what they must have been thinking just happened in front of their eyes. They thought Belle had purposefully deepthroated me when she'd felt I was about to cum, letting me empty my load straight down her throat. I looked at Belle, who, having recovered, was about to resume blowing me, and stopped her.

"Let's go. They got their show. Time to move," I whispered as I pulled up my briefs and my shorts.

"You're sure? But you didn't cum yet..."

I grabbed her wrist and helped her to stand. "Yes, get decent, wave at them, and let's hit the road."

She complied. While we were running, I explained what the guys had mistakenly thought happened. Belle seemed disappointed.

"That's what I wish would have happened..."

I looked at her tenderly. "No need to push your body further than its own limits for me, honey. I know you're a pleaser, but that can't have felt good for you."

She nodded, but after a few seconds asked "Did it feel good for you? Honestly?"

I sighed, knowing where this was going. Once she had an idea in her mind, she would not let go that easily, often regardless of my attempts to discourage her.

"Honestly, it just felt different, nor better nor worse than a normal blowjob."

She snorted. "Come on! You're not really 100% honest, I can feel it."

I stopped running. "Okay. Since you insist and wanna know all the details, yes. It did feel good. Your throat around my glans felt a bit like your pussy does. The few times you managed to move your head felt a bit like an impossible scenario where my shaft was being sucked while I fucked with only the tip. And all the swallowing you had to do felt good too, though I can't think of anything to describe what it felt like..." She opened her mouth to talk but I lifted my hand to tell her not to interrupt. "But, and that's a massively huge 'but', seeing the tears in your eyes and the obvious discomfort it put you through, was an instant turn-off. Even if it had felt like the best thing ever, which it didn't, I could never have come while seeing you suffer through it."

She waited a few seconds to make sure I was done, then nodded.

"Okay, I get it, it felt pleasant, not best-thing-in-the-world pleasant, but pleasant nevertheless. And my obvious discomfort killed your mojo." She lifted her hand as I'd just done, even though I'd had no intention of cutting her off. "But now that I've managed to do it once, I think I know how to do it again. And I'm convinced, given how it felt, that with a little practice I can make the discomfort disappear, or most of it. And, I felt really proud when I realised I'd done it, which massively turned me on... That should count too!"

I sighed, she'd even managed to turn my 'massive' argument back to me. I reviewed all the arguments I could try to oppose hers, but knew I'd get nowhere with them. I had to concede defeat.

"Let's make a deal then. I know I can't keep you from trying again anyway, so what would be the point in pretending otherwise. But I want you to promise me you won't try to power through it like you did today. No point in making yourself vomit all over my dick..."

She was smiling triumphantly when she said, "I promise," then hugged and kissed me.

We walked the rest of the way home, cuddled against each other, our need for a bit of tenderness trumping the initial purpose of this outing.

As we arrived home, she pushed me against the wall of the corridor and blew me off, without trying to deepthroat me. But simply sucking my dick must not have been enough in her head, because I soon felt one of her fingers slipping within my crack. She caressed my butthole for a while, before pushing it in. I felt her finger slide further in, and she continued blowing me off while massaging my prostate.

I came hard. I had to push myself against the wall to remain upright when my knees went weak. I closed my eyes and just unloaded, my whole world reduced to that one finger inside my butt. When I finally opened my eyes, Belle removed her finger and stood up. Her face was covered with my seed, I had not even felt her removing my cock from her mouth. She gave me an evil grin.

"See? If you'd come down my throat as I wanted, you wouldn't have made such a mess."

She grabbed a strand that was about to drip from her chin with a finger and brought it to her mouth, sucking on it and letting out a small 'yum'. Then she left me there, still leaning against the wall as if my life depended on it.

She would try deepthroating me again many times, and pushed herself a bit too far for most of them, though never far enough to actually throw up. I showed her my disappointment each time she did so, even putting a stop to everything once after I heard her gag particularly hard. The fact that I didn't care about the potential blue-balls to punish her for not respecting our deal seemed to have its effect, she never tried to power through it this hard afterwards.

But one day, be it because she slowly got used to invading her own throat with my cock, or because she'd finally found the 'trick' she'd been looking for, I felt my dick slide down her throat without her slowing down. I looked down only to see her deep brown eyes smiling with triumph. I slowly shook my head, letting her know what I thought about her hardheadedness. But I ended up cumming directly down her throat, as she'd wanted me to.

But that wouldn't happen before the end of summer. A lot more happened in the meantime.
