We didn't see Geoff the next day, deciding to take a break for ourselves to get some of our errands completed.

We discussed further exploration of a new dynamic between Zara and Geoff. We talked about when we'd experimented with freeuse before and how we enjoyed that. The idea of Zara serving the sexual desires of Geoff in a sort of freeuse dynamic really excited us both.

Through messages and a call we discussed the concept with Geoff, much to his delight. From now on; whenever Geoff was round our place, if Zara was wearing a bikini or less, Geoff had free reign to use her as he wished. With respect maintained at all times, which he completely agreed with of course.

We weren't ready for actual sex, so that was off the table. But everything else was available.

Me and Zara immediately fucked, me bending her over the bed, after the call as our excitement couldn't be contained any longer.

A few days passed into next week, when after dinner I asked Zara if she wanted to put on a bikini and invite our neighbour round.

She smirked and jokingly swatted my arm. "Well at the very least I'm glad to see that you want me to." She then disappeared upstairs to change.

My phone buzzed as I was tidying away dinner. There was a message with a picture in our three-way group chat of Zara standing confidently in front of our full-length mirror in just a white bikini. The message read "Come on over, if you're free to."

I didn't feel any need to change, so brought my book out to sit at the table. Zara joined me in her less revealing, but still sexy, white bikini with her own book.

There was no reply to her message. That was until Geoff came through the side passage dressed in a t-shirt and shorts.

He smiled and waved at us. We welcomed him. I couldn't help but chuckle under my breath that even when he was joining us with the express purpose of using my wife for his pleasure, he still had the demeanour of just a warm and friendly neighbour.

He joined us at the table. Zara got up to get us some water quickly.

"So...." Geoff trailed off in an unsure manner.

I laughed, "We're all in agreement on this mate. And very excited about it to be honest. So you do you." Then with a joking head tilt I added "Well, you do my wife actually."

We both laughed and I saw him relax.

Zara returned with water for all of us. Geoff stared at her sensuous figure as she sashayed over.

After she placed the glasses and sat down we all chatted happily about general stuff. Geoff then asked if we had a towel, I fetched him one from nearby.

As I handed it to him I pointed out he wasn't really dressed for a swim. He replied "Oh, it's not for me. It's for your wife." As he folded it over and placed it at his feet.

The familiar thrill rushed down me as I took my seat and saw Zara blush slightly.

"Zara, would you like to just kneel on this?" He motioned to the towel mat he'd made at his feet.

Zara's breath caught, but she just nodded before sultrily slipping down to kneel between Geoff's legs.

He reached for his zipper, but Zara's hands stopped him. "Allow me." She whispered, looking up into his eyes.

Zara pulled the zipper down before shimmying his shorts and boxers down his legs.

His cock rested on the chair, so large it was actually hanging slightly over the end of it.

My wife leaned down to lick the end of his cock, swirling her tongue around it before slurping it into her mouth. Geoff's cock rapidly hardened at the sight.

Zara, upon feeling this, suddenly threw her head forward to try and stuff as much of his cock into her as possible before it expanded to full hardness.

There was a loud 'GRLLK' as she got her lips three quarters of the way down his shaft. She grabbed onto his hips again and pulled her head forward as much as she could.

Geoff exclaimed in surprise and pleasure. As his cock quickly grew to full size at the sight and feeling of my wife desperately forcing it to stay lodged in her mouth.

Her valiant efforts were in vain though. As his cock throbbed hard, it had pushed her lips back to only over half way along its shaft now it was at its larger size.

Zara made a disappointed whine into Geoff's dick, before sucking her way back off it, it popping out of her mouth. "Damn. Have to try something else next time." She opined, tapping our neighbour's cock against her chin like she was absentmindedly thinking through a problem.

Then with great enthusiasm she returned to sucking and slurping along his shaft, lavishing her tongue all over it while her hands fondled his balls.

Her work coated his cock in a sheen of her spit, as well as her face as she rubbed his cock over herself.

Engulfing him again, she sucked on his head while swirling her tongue around it every so often. One her hands stroked up and down his shaft, her fingers never close to closing around it.

I sat there, in the warm evening, watching and listening as my wife blew our old overweight neighbour just in front of me. I thought how weird a turn my life had taken recently, as I stroked myself under the table.

Zara continued her work as Geoff sipped on his ice water. Drool was now running down her chin and neck to pool between the pressed mounds of her breasts.

After he slowly finished his drink, savouring every second of it, Geoff gave a deeply satisfied moan. He looked down at my wife, worshipping his cock and groaned again.

"I want to use your tits. You have the tits if a goddess, I want to fuck them." He declared down to her.

Zara's eyes shone at this demand and I saw a shiver run down her spine. She nodded around his cock and slurped off with a loud pop.

She rapidly pulled off her bikini top, then pressed her shining tits around his already well lubricated cock.

Geoff released an enraptured moan at sight and feel. My wife, on her knees before him. Beautiful blue eyes shining up at him, as she pressed her magnificent breasts up and around his monster cock.

I was struck by the scene before me, Zara's silky hair tumbling gorgeously down her arching back. Her supple ass raised up and tilted out, again, invitingly.

Even with my wife's DD size, Geoff's cock emerged out the top far enough to prod her chin whenever she looked down at it.

Zara slid herself back and forth repeatedly along Geoff's cock, staring intently up at him the entire time, much to Geoff's delight.

After a while the constant prodding of her chin caused her to take his dicks cue, and slip his head past her lips. Popping it in and out as she leaned forward and back.

Geoff's hips started to buck and thrust, pushing his dick into Zara's mouth from between her tits.

The fervour increased for both of them, as they simultaneously hummed and moaned in pleasure. Geoff's thrusting took up more force and focus as he reached down and held onto Zara's head.

I saw a strong shudder of ecstasy roll down her body when he held her.

Our neighbour drove his cock up and through my wife's breasts as they mashed around him. His cock head popping in and out past my wife's lips repeatedly as she moaned into it. His intensity reached a peak until he suddenly thrust up with a bellow of euphoria and held my wife's mouth just over the head of his huge cock, as it pulsed past her lips.

Zara cried out in satisfaction as Geoff pumped load after load of cum straight into her mouth. Her cheeks bulged with the amount of it, even as she gulped it down her throat, until some strands leaked out past her lips to drop onto her breasts.

My wife slurped her lips and tongue around the top half of his cock, after he finished emptying himself into her. Cleaning all the stray cum from him and swallowing it with loud enjoyment.

Then she let his softening cock slip from her mouth to brush over her slick tits.

Zara massaged the spit and cum into her tits, humming happily to herself.

Geoff dropped back into his chair, staring up at the sky in bliss.

I called Zara over to me. She smiled and climbed into my lap, slipping my hard cock into her soaking pussy as she did so.

She rode me violently, gripping into the table edge as I thrust up into her. It wasn't long before we both cried out each other's names as we climaxed together.

She sank down to rest her back against my chest. She rolled her hips with my cock still inside her, eliciting another groan from us both.

We turned from staring lovingly at each other, towards Geoff as he stood and pulled his shorts back up.

"That was, well that was indescribably good." He chuckled. "I'd love to stay longer but it's getting late and I have to get to the office early tomorrow."

We wished him a goodnight and headed in ourselves as he departed.

Zara cleaned her teeth. We showered together, soaping each other up between passionate embraces and kisses. Then we snuggled up in bed ready for sleep.

Before we drifted off, we both discussed how incredibly excited we both were to see how this continued.

It seemed this summer was certainly going to be one to remember.

I watched with a smile as my beautiful wife eased herself down our old and overweight neighbour's cock. Her mouth stretched around his thick shaft, reaching just over halfway down its length.

It had been a couple of weeks since we had agreed on the new dynamic between my wife, Zara, and our older neighbour Geoff. Since then she has serviced him several times. Sucking, rubbing and titty fucking the cum out of his monster cock; all over herself.

The dynamic was, that whenever Geoff was round our place, if Zara was wearing a bikini or less he could use her as he wished. We weren't yet comfortable with any full sex though, and he had to be respectful at all times.

We had started by inviting him over to hang-out in our new backyard pool and hot tub. Now we simply sent him a pic of Zara in a bikini to invite him round.

Mine and Zara's passions for each other were now burning with a greater intensity than ever before, each neighbourly visit adding further fuel to the fire.

After several minutes of luxuriously working on his dick, it was now shining with her spit. She pulled herself off with a pleased hum, then lifted his huge cock straight up and dived in to suck on his equally huge balls. Zara repeatedly lifted Geoff's weighty cock and let it smack down on her face with an audible slap, she grinned up at him each time.

"God damn Zara, you've really risen to new levels at this!" Geoff groaned through gritted teeth. She beamed at his praise, wiggling her perfect ass tantalizingly.

"Still not at the level I want to be at though." She sighed as she suckled at the base of his shaft.

"Don't worry love, you'll get there eventually!" I half-jokingly encouraged my wife. She and Geoff both chuckled. Turning towards me, her striking blue eyes connecting with mine, she maintained eye contact while forcing her mouth down his length until the heavy cock head pressed against the back of her throat. Yet again, as had occurred so many times over the past two weeks, Zara's progress was halted with a loud gag and a choke.

Drool dripped off her chin onto her swaying DD breasts as she held her mouth as wide open as it would go, stretched to its limit by Geoff's thickness. She coughed and spluttered before having to pull back, her eyes watering slightly. "One day." Zara determinedly muttered.

"You've already gotten as far as anyone else ever has, Zara. Not even my wife could take it all the way." Geoff 'consoled' her as she sucked and licked around the bottom half of his cock.

My wife continued to suck and stroke our neighbour's mammoth cock for the next several minutes. Taking her time to savor getting to pleasure such an impressive piece of equipment.

Zara increased the intensity of her stroking along his shaft and head, her face now buried in his sack as she tongue-bathed his balls. Geoff started to buck his hips and groan louder.

"Mhare myu mhonna hmm?" Zara attempted to ask something, but Geoff's weighty sack muffled her too much. She pulled back with a deep breath, lines of spit still connected from her lips to his balls, "Where you wanna cum?" Zara asked up to Geoff, before immediately moving back under to suck one of his testicles into her mouth.

"Your face! I have to coat your beautiful face!" Geoff exclaimed with a stifled roar of pleasure.

Zara's eyes twinkled in delight. She kneeled up, kissed the end of his cock and pumped harder. "Cover me, coat my beautiful face in your cum." She moaned, her lips and tongue tickling his tip as she stared up into his eyes.

Our neighbour released a roar of ecstasy as cum erupted to smack her on the lips. Thick streams sprayed onto my wife's face as she tilted her head back, blasting from her chin up and into her hair. She smiled in glee the entire time, until her face was painted white.

Zara wiped cum from over her eyes with a giggle, then used her mouth to thoroughly clean the end of Geoff's cock with a satisfied moan.

I fetched her a towel to clean her face, then we all relaxed back into the hot tub.

As we enjoyed the warm evening, idly discussing recent events, I noticed Zara subtly playing with herself under the bubbling water.

I sidled over to Zara and put my arm around her shoulders. She shifted to rest against me comfortably.

While continuing to talk to Geoff about my intention to improve my exercise routine, I slid my other hand up Zara's smooth thigh.

She spread her legs, inviting me to continue. My fingers felt how wet she was, even with the hot water washing over her lips. I circled my fingers over her clit and entrance. Zara's breathing shallowed as she tried to hide her pleasure.

I enjoyed teasing my wife while we continued the conversation. She did her best to stifle her moans of pleasure, trying to not interrupt, but I could tell that Geoff knew what was going on.

I reached two fingers into Zara's pussy, stroking them in a curling manner repeatedly. She turned her head and released a groan of delight into my shoulder.

At this outburst, Geoff grinned at me as Zara started to drop all pretense.

He moved over to the other side of Zara and started to paw and play with her heaving breasts, causing another released groan of pleasure.

I continued fingering Zara, eliciting further moans and sighs from her as she rolled her hips with my movements.

"I'd like to go down on you." Geoff suddenly announced.

Me and Zara both paused and looked at him. Geoff had fingered Zara to climax before, but this would be new for us.

"We agreed I could use her as I wanted, just no sex. Well she's gone down on me a lot, I'd like to return the favor."

Me and Zara looked at each other. His suggestion had triggered a strange mix of jealousy and arousal in me; the same as when Geoff had fingered Zara to climax before and when she kissed him. I'd be lying if I said I didn't want to see how I would feel watching him finish her off with his mouth.

I smiled with a shrug, not wanting to give away how much my excitement was building. Zara gave me a strong kiss then raised herself up onto the side of the hot tub and spread her legs.

With her devilish smile she looked expectantly at Geoff.

Smiling from ear to ear, Geoff lifted Zara's closest leg and maneuvered himself so he was between her thighs, his face inches from her sex.

There was a brief moment, where all of us held our breaths in anticipation, before Geoff dove in.

My wife threw her head back as she groaned loudly. Geoff's hands ran up and down her toned thighs as he devoured her. Her groans continued, growing in volume, chest heaving as her breaths became ragged and gasping.

The mixture of emotions surged in me, the combination hitting me like a strong drink

I could hear how wet she was, gushing all over our neighbour's face. She groped her own big tits, twisting the nipples and massaging them, enraptured in the pleasure coursing through her.

Her hips rolled, her plump and juicy ass pressed out to form beautiful hip cleavage. I could see her tight abdomen flexing and her back arching. Highlighting how fit she was and the stunning sexiness of her body, in stark contrast the flabby old bald man currently causing her such pleasure.

With her eyes shut in delight she ran her hands through her own hair, lifting her boobs higher on her chest. Her rapid breathing causing them to shake and bounce, glistening in the setting sun.

Suddenly she bent forwards, gripping onto the sides of Geoff's head. Her panting became short and sharp, near screams of ecstasy. The intensity of her pleasure built and built until her back arched forwards, thrusting her tits out, as she wailed in ecstatic release. Her legs shook and powerful spasms shot down her back. She rode out the orgasm as it rushed over her in waves, until it finally subsided.

Her hands ran through her hair again as her eyes opened, wide in surprise.

"Fucking hell Geoff, how did you do that!?" She gasped.

Our old, overweight neighbour pulled away from my wife's pussy, his face drenched in her cum.

"Just, you know, experience." He grinned up at Zara. "But that was a particularly great reaction, no one's ever gushed over me like that before."

Zara blushed slightly at his praise. "Well you have to do that again sometime. No way that's only happening once." Geoff laughed in response and nodded an "Of course!"

As Geoff returned to the other side of the hot tub, Zara took my hand and whispered to me "Are you ok love? I'm sorry, I didn't expect it to be like that."

I cleared my throat, my mouth had gone slightly dry from gaping at the display before me. "I'm good."

"Are you sure? I'd understand if you weren't ok, I just want you to be honest with me."

I slid my swim shorts down, revealing my raging hard-on. "Oh," Zara said with a surprised smile.

I grabbed her, and pulled her over to straddle me, then without hesitation thrust myself up into her soaked pussy. I'd never felt her so wet before. It felt incredible.

Zara wrapped her arms around me as I bounced her with all my strength on my cock. She moaned and groaned into my neck "Oh god, so soon.... It feels so gooood."

My lust for my wife burned through me. Her pussy was so hot and wet, it had never felt this amazing before. There was no way I was going to last much longer.

"Cum with me." she whispered into my ear. "You feel so good, just what I need. Please cum with me, cum in me. Make me yours again."

With a shout I came in her, thrusting up as deep as I could go. As I did, I felt her gush around me as she shuddered in release.

Zara softly kissed my chest, before climbing off to sit, pressed against me.

Geoff smiled at us from across the hot tub "You two look so perfect together."

We thanked him and held each other tightly.

Geoff offered to get us all a drink, which we accepted, to get a chance to catch our breaths.

When he was inside I asked Zara "I really am ok, that was SO hot to see you cum like that. I just have to know, was it better than me?"

She squeezed me in her hug and looked into my eyes, "Honestly, it was harder, but in a different way. Not better."

"With us there's a deep connection, a love, it's genuinely on another level."

She took a moment to think, "That was purely physical, it consumed my body, but my mind was almost blank. There was some element of taboo or extra excitement that it was our older neighbour doing that to me. But that was it, just physical, nothing more."

Zara kissed my neck, "How do you feel about that?"

"Good. I mean it, it was incredible. Thanks for explaining it like that. I love you."

She smiled back at me, "I love you too."

"I just also have to ask. Just before we finished while you were riding me, you said 'make me yours again.' Did you mean that?"

I saw her blush when I asked that, she took a deep breath then replied "Yes. As I said, it consumed my body and left my mind almost blank. It was like I wasn't myself anymore. I needed you, to reconnect with, and return back to normal."

I looked at her with concern "That sounds kinda scary, that you felt that thrown out of your normal self. Like a bad trip?"

"No, it was much calmer than that. Very relaxing actually, in the moment. Like a happy dream. All troubles and concerns melted away, just pleasure."

"So you reconnecting with me, was all your troubles and concerns returning?" I asked.

She jokingly slapped my arm, "No! It was like waking up from a very restful nap. Waking up in your arms. It was beautiful." She smiled lovingly.

That erased all my doubts. "Oh, well that does sound lovely."

She couldn't help but wistfully sigh, "It really was."

We embraced tighter and I kissed the top of her head, then we slipped back into the hot tub.

Geoff returned a short time later with three glasses of water. After we finished them all, we exited the hot tub, and passed each other towels to dry off. Geoff said it was getting late and he would head back.

We thanked him for coming over, and said we'd do it again soon, same as always. But as he was about to walk off, Zara cupped his face with one hand and pulled him into a deep kiss.

The sight of my wife making out with the neighbour, her naked tits pressed against his chest, re-lit the mixture of jealousy and excitement in me. Then she pulled away, thanking him again.

We barely made it halfway into our kitchen before I grabbed her from behind, mauling at her tits.

"Oh you liked that did you?" She sultrily said over her shoulder.

I bent her over our kitchen Island, I could see she was already wet.

Taking her perfect ass cheeks in a strong grip, I thrust my cock back into her. She moaned loudly and spurred me on.

Loud slaps echoed around the room as my hips thrust against Zara's ass, joining the chorus of our cries of pleasure. As the cacophony built to a climax we came together.

I kissed her neck as she stood up and we embraced, then we headed upstairs to shower.
