It was a really hot day in the middle of the summer, probably one of the hottest days of the year, but at the outdoor centre, it was work like usual.

Now, half way through the afternoon, I was asked to take a large container of fresh cold water, and dozen plastic cups down to the lake, to make sure our guests were drinking enough fluids.

The lake was where we did our canoeing and raft building activities obviously, but it was right at the far end of the centres grounds, so it took a good few minutes to walk there, which is why I was given the job of taking fresh cold water to them, to save time.

Anyway, when I got down there, I discovered Erica was running the canoeing activities that day, and my face instantly lit up when I saw that hot skinny red head, in her works t-shirt and swimming shorts.

She looked very hot as she at all times did, and her white t-shirt stretched over her big D-cup boobs so much, I swear I could practically see her nipples poking through it.

Anyway, I eagerly strolled towards her, and said cheerily “Hey! I’ve brought some fresh cold drinking water, for your group!”

Erica was busily checking over the canoes, before the group arrived, and simply replied back “Great! Put it over by the shed, and then pour a few cups out ready.”

So I did as I was told, and as I finished pouring the last cup of water out, she came strolling over to me.

“So, have you got an activity you need to get too now, or can you stick around a while?” she then asked casually.

“Um. No, I’m free for the moment.” I replied casually back, because I had been taken off the afternoon activities, so I could do water runs for people.

“Cool.” My senior instructor replied casually again.

She then glanced around, as if she was checking to see if anyone was nearby, but her group hadn’t arrived yet, and there was no one in sight, so, then she said to me quietly “Hey. Do you want to see something interesting?”

“Okay?!” I replied back curiously.

Now, Erica, as I’ve said before, was a senior instructor, which meant she was very suitable and experienced in outdoor activities, and usually, she was pretty strict about work, and didn’t often joke around, unless she was being sarcastic to someone, she loved being sarcastic to people.

However, unbeknown to everyone else, we were secretly fucking, despite the fact she had a long term boyfriend, who also worked at the centre, and was also senior instructor.

So, when she said ‘Do you want to see something interesting?’ I was really curious to know, what her definition of interesting, was?

Erica then turned away from me, took hold of her white and black swim shorts, and pushed them down to her knees, revealing her skinny white little butt.

Then she placed her hands on her arse cheeks, and pulled them aside, to reveal her arsehole, and a glittering blue heart shaped crystal covering it.

“What do you think?” she then asked with a grin on her face, as she glanced back at me over her shoulder.

“Holly fuck! Is that a… butt plug?” I asked back in amazement.

“It sure is!” she replied excitedly, wriggling her arse at me, before she then said “And if you stick around until my group leave, I might even let you pull it out… and take its place!”

Well, I certainly couldn’t say no to that, could I?

So, excitedly, I agreed to hang around and help her with her group, and quickly she pulled up her shorts again, just before they started to appear through the woods towards us.

Anyway, the next couple of hours quickly flew by, as Erica took her group out on the lake, and tried to teach them how to paddle a canoe, while I tried to help from the edge, and eventually, it was time for everyone to get off the water.

Once everyone was back on dry land, the little group of clients strolled off back to the centre, to change, and get ready for the evening meal, while, Erica and I emptied the canoes of water, and then stored all the paddles back in the shed.

After we had cleared up, I was closing the door to the shed, when my skinny senior instructor stepped up next to me, and whispered in my ear “So, do you want to head back to the centre for something to eat, or do you want to eat, right here?!”

I grinned excitedly, and then replied “Oh, I think, I’ll eat here!” and instantly, Erica grinned back at me.

She then turned around, facing away from, leant against the shed, and then said “Well, getting eating then!”

Eagerly, I moved behind her, placed my hands on her shorts, and swiftly pulled them down, exposing her lovely little pale round buttocks.

Erica then stepped out of her shorts, widened her long legs a little, and then waited for me to start.

So, I knelt down behind her, placed my hands on her skinny cheeks, and eased them open, revealing that little gem studded arse plug again.

I then took hold of the little butt plug, and gently, began to pull on it, and as I did, her little pink ring began to stretch with it,

Incredibly the more I pulled, the more her arse ring stretched, and Erica moaned softly because of it.

Then, when her little arsehole couldn’t take anymore, it let go, and there was a little pop noise, as the plug finally came free, and her arse ring relaxed again.

“Oh, yeah!” Erica moaned in delight, as I slid the plug out of her hole.

Once it was free, her arse remained open, almost like it was now stuck in that position.

So, as it was ready for me, I leant in, stuck out my tongue, and pushed it into her arsehole.

“Oh yeah!” Erica moaned in pleasure, as she felt my wet pink tongue, slide into her gaping rear.

I then eagerly began swirling my tongue around inside her lovely little rear, and Erica gripped the side of the canoe shed, and moaned even more in pleasure, as I did that.

“Oh yeah! Oh yes! Lick my arse! Lick my arse!” she moaned in pleasure.

Keenly, I continued to swirl my tongue around inside her butt, and Erica was enjoying it so much, she started to grind her little rear against my face.

“Oh yes! Oh yes!” she moaned again, clearly enjoying what I was doing to her.

After a while, I then switched from swirling my tongue around, to probing her skinny butt, pushing my tongue in and out of her arse, like it was a mini wet cock.

This made my ginger headed senior instructor groan excitedly, and she leant more on the wooden shed, as I tongue fucked her rear.

For a good couple of minutes, I happily plunged my tongue into my senior instructor’s arsehole, willing to hear her moan in delight, because my mouth meat was jammed into her hot little butt.

Then, when her arsehole was dripping with my saliva, Erica turned her head towards me, and said eagerly “Steve! Fuck my arse! Please fuck my arse already!”

Well, that’s what I was there for, so eagerly, I pulled my tongue from her rear, quickly stood up and undid my blue cargo shorts, and as soon as they dropped to the floor, I stepped out of them, and then took hold of my almost fully erect cock, and stepped up behind Erica.

My ginger supervisor watched over her shoulder excitedly, as I then placed my big round bell end up against her wet gaping arsehole, and then, with a thrust, slid into her.

“Oh yes!” she then moaned in delight, as my big firm dick pushed into her skinny arse, and filled her back passage.

I slid most of the way inside of her, her arsehole was so open and wet, before I placed my hands on her skinny waist, eased my length back, and then thrust in again.

“Oh, yes!” she moaned again in pleasure.

Then excitedly, I began pumping back and forth inside her, eagerly fucking her wonderful little arse, and as my dick slid in and out of her wet back passage, she moaned even more in pleasure.

“Oh yeah! Oh yeah! Fuck my arsehole! Fuck my arsehole!” she exclaimed excitedly.

So, I happily did, and as she leant against the shed, holding onto it to keep herself from falling over, I held onto her skinny waist, as I pumped firmly into her butt.

“Oh yes! Oh yes! Oh yes!” she moaned in delight again.

It had been a while since we had fucked, for one reason or another, so I was keen to fuck Erica as well as I could, and eagerly continued to pound into her, as I held firmly onto her.

“Oh yes! Oh god, yes! Yes! Yes! Yes!” she exclaimed in pleasure again.

In that glorious hot afternoon sunshine, I keenly plunged in and out of her little arse, giving her the fucking I know she wanted, and Erica continued to moan in delight.

For a good while we fucked like that, before Erica moved one of her feet up onto the water container, leant back towards me, turned her head, and eagerly pressed her lips against mine.

We immediately started to kiss, happily massaging each other’s lips with our own, while our wet tongues explored each other’s mouths, and as we kissed, my thrusts slowed to long deep strokes, and Erica moaned softly into my mouth.

“Oh god. I’ve missed your cock in my arse!” she then whispered between kisses.

“Yeah. I’ve missed it too!” I replied happily back, before adding “So, I’m just going to keep fucking your arse, until the sun goes down!”

“Promise!” she replied with a grin.

“Promise!” I replied back, before we continued to kiss.

Of course, that wasn’t gonna be entirely feasible, as her boyfriend, the assistant manager of the centre, would probably come looking for her when she didn’t show up for dinner, and there was also evening canoe sessions, but, it was the sentiment that counted.

Anyway, for a while, we kissed and steadily fucked, until Erica pulled her soft wet lips from mine, and then said keenly again “Fuck me harder! Fuck me like you want to brake me!”

I grinned back at her, and then started to pump faster into her arse, and as I plunged harder into her, she let out a loud moan of pleasure again, and then leant forwards, against the wooden shed again.

Back in that position, I could really pound my cock into her, and as I slid my big firm dick in and out of her wet arsehole, she stood with one foot up on the water container still, groaning in pleasure, as our hot half naked bodies slapped together repeatedly.

“Oh yes! Oh yes! Oh yes!” she exclaimed excitedly, as I fucked her butt relentlessly.

As I happily fucked Erica’s skinny pale rear, I slid my hands around her body, and under her shirt, before moving them onto her big soft D-cup boobs, and quickly discovered why her nipples had been poking through her top, she wasn’t wearing a bra.

So, eagerly, I held onto her lovely soft big tits, as I continued to thrust into her arsehole, and Erica continued to moan loudly in pleasure.

After a couple of minutes of fucking her hard, while fondling her lovely big boobs, Erica then reached down, took hold of her white works t-shirt, and pulled it off.

She quickly dropped it onto the ground, beside her shorts and the arse plug, and now she was completely naked, but she didn’t seem to care, she just wanted me to keep fucking her arsehole.

So, I did, and happily gripped her big boobs, while I repeatedly plunged my firm length, into her butt.

“Oh yes! Oh yes! Oh god, I love how you fuck my arse! I love it! I love it!” she then moaned in pleasure.

For some time, I happily fucked her like that, and as I continued, her cries of delight got more and more excited, until finally, her head started to tilt back, her bare back began to arch, and she exclaimed excitedly “I’m going to cum! I’m going to cum! I’m going to…”

I plunged into her little butt hard and deep once more, and as I slid all the way in, and my balls smacked against her little bald pussy, she cried out “CUM! OH GOD! CUM!”

Her skinny pale body then tensed up, lifting her up onto her tip toes almost, before she started to tremble and shake, as her first orgasm shot threw her.

“Oh god! Oh god!” she then groaned in pleasure, as she continued to cum.

For a good few wonderful seconds, my ginger senior instructor came hard on my cock, and I felt her little arsehole squeeze my firm length, as she shook and moaned uncontrollably.

Her orgasm seem to go on for almost a minute, and it was so hot to watch her cumming, knowing I caused that, but eventually it finally stopped, and with a big happy sigh, she relaxed.

For a moment Erica stood catching her breath, with a big smile on her face, before she eased herself off my rigid member, and then turned and kissed me.

Passionately, we explored each other’s mouths again with our tongues, as our lips clamped together, and as we kissed, her slim bony hand found my hard wet cock, and steadily, she stroked the cock that had just made her cum.

We kissed for a minute or two, before finally my senior instructor pulled her lips from mine, and then with a grin, led me over to the up turned canoes.

“Now do it again! I want to cum on that cock again and again!” she said eagerly.

She then climbed on top of one of the canoes, before lying back on it, and then she lifted her skinny white legs into the air, giving me a perfect view of her pink little arse ring and her bald little pussy.

Erica then grinned at me, waiting for me to enter her, and eagerly, I moved up to her, before placing my hard length, up against her little pink bud.

I then started to ease it into her, and with a small thrust, my firm cock slid back into her, filling her arsehole again.

Erica happily moaned in delight, as I filled her skinny rear with my dick again, before she then rested her slim pale legs on my shoulders, as I started to fuck her again.

Keenly, I slid my firm length back and forth inside her little wet arsehole, and as I fucked her butt again, she let out more moans of pleasure.

“Oh yeah! Oh yeah! Fuck my little arsehole! Fuck it! Fuck it!” she exclaimed happily, as I did just that.

My hard cock slid in and out of her moist rear again, and as I happily thrust into her, Erica moaned in delight.

“Oh yeah! Oh yeah! Oh god yeah!” she exclaimed in pleasure, as I continued to fuck her arsehole.

For a good while, I keenly fucked my ginger supervisor in the arse, while she lay happily on her back letting me, and even though we were in a fairly open place, where anyone might see us, neither of us right then, really cared.

After a while of steadily pumping her, I took hold of her long bare legs and eased them back a little, almost folding her in half, before I lowered my head, and clamped my wet hungry mouth around one of her big pink nipples.

Instantly, Erica moaned more in pleasure, as I began sucking on one of her big soft tits, and as I did, I continued to thrust steadily into her arsehole.

“Oh god! Oh god! Oh god!” she gasped excitedly, clearly enjoying what I was doing.

Keenly, I then switched my mouth back and forth, happily sucking on one of her big fleshy globes, before switching back to the other, and as I did this, my hard dick continued to slide in and out of her moist little rear.

“Oh Steve! You’re going to make me cum again! You’re going to make me cum again!” Erica then moaned excitedly, as I kept going.

As soon as I heard that, I got pretty excited, and began thrusting harder into her arse, and as I did, Erica groaned louder in pleasure.

“Oh shit, yeah! Oh shit, yeah!” she cried out, as I rapidly fucked her skinny pale butt.

Eventually, I had to stop sucking her wonderful big tits, so I could pound her little arse properly, and as I stood up right again, I hammered her wet arsehole with my big thick length.

“Oh god! Oh god! Oh god! Oh god!” she then exclaimed excitedly, as I fucked her hard and fast.

As my rigid member plunged into her rear, pounding her little butt the way she loved, she cried out wildly, and stared up at me between her legs, willing for me to make her cum again.

“I’m nearly there! I’m nearly there!” she then moaned excitedly, as I continued to pump her rear vigorously.

Then, as I slid my firm cock into her again, going in balls deep, Erica’s blue little eyes widen fully, and she exclaiming urgently “I’M CUMMING! I’M CUMMING! I’M… CUMMING!”

I slid hard into her lovely wet arse once more, and then her skinny body tensed up, and then she roared wildly “OH FUCKING GOD!”

As Erica’s second orgasm hit her, she screamed out loud, before I felt her arsehole start to tighten on my length again, and her body began to buck uncontrollably.

My hot senior instructor groaned heavily, and trembled hard, as she came on my cock, and all I could do was stay deep in her lovely little arse, as she had another orgasm.

For several wonderful seconds, Erica moaned and twitched excitedly, cumming again and again in total euphoria, until finally, she took a sharp deep breath in, and then relaxed with a sigh.

“Oh Steve!” she then moaned softly, as she tried to catch her breath again.

As she lay beneath me, breathing heavily, I leant down towards her, before our lips touched, and we started to kiss passionately again.

Our willing lips caressed each other’s, as our wet tongues wriggled together swapping saliva, and while we were kissing, my hard dick was still buried in her little back passage.

Then, after a while Erica pulled her mouth from mine, smiled, and said “Sit on the canoe. I want to ride your cock!”

So, I eagerly pulled my firm member from her little moist arse, and then sat down on the up turned canoe, next to her, before my ginger headed supervisor then stood up, and straddled my legs.

Facing away from me, she then positioned herself over my upright dick, before slowly, lowering herself down on it.

Her little pink arse bud then touched down, on the top of my bulbous cockhead, before it eased open, and her arsehole slid down my shaft.

“Oh, yes!” she moaned in delight, as her little rear was filled with my thick length again.

Erica then placed her hands on my knees, crouching over my waist, before she started to raise herself up, and then sink back down again, and steadily, she started to ride me.

“Oh, yes!” she moaned in delight, as her little moist arsehole slid up and down my rigid cock.

Erica then moaned again in pleasure, as she continued to fuck her lovely pale rear on my dick, and as she lifted and dropped onto it, I got to see it in all its glory.

“Oh yeah! Oh yeah! Oh yeah!” she then exclaimed in delight, still happily riding my length.

This was wonderful I wondered, it was a hot bright afternoon, beside a picturesque lake, in the lovely green lush countryside, and this hot ginger headed woman was happily riding my member, yes, this was why I got into the outdoors!

For some time, Erica continued to slide her little back passage up and down my stiff member, happily riding my cock, and moaning in pleasure as she did.

Then, after a while, she slowly leant back, until she was resting against my chest, before she looked up at me, and said “Fuck me Steve! Fuck me!”

So, I slid my hands down under her lovely slim thighs, and pulling them up a little, until her feet were pointing skywards, I began thrusting up into her butt.

“Oh yes!” she instantly moaned out loud, as my hard cock pushed up into her arsehole.

Eagerly, I started to pump into her again, fucking her fast and hard again, and as I did, she cried out excitedly, clearly loving what I was doing.

“Oh fuck yeah! Oh fuck yeah! Yeah! Yeah! Yeah!” she exclaimed in delight, as my firm dick slid rapidly into her arsehole again.

I was now thrusting hard up into her skinny little arse, as she laid back on top of me, and as I shoved as much of my rigid dick into her, Erica moaned excitedly.

“Oh yes! Oh yes! You’re fucking my arse so good! So fucking good!” she exclaimed in delight, as I kept going.

For a good while, I held Erica in that position, balled up on my chest, as I rammed my firm length into her arsehole, and I would have just kept fucking her like that, until I came, but, after a little longer, she wanted to change position again.

So, I thrust up into her arse once more, and then eased her over onto her side, and once she was lying on the canoe, next to me, I continued to pump into her.
