The car trip didn't take long, thanks to mom's exceptional navigational skills. A weekend in the countryside was the perfect way to celebrate the end of the school year, as a big, happy family. Almost! You see, dad was missing for business as usual. But, then again, who needs him? One of mom's relatives had decided to allow us to stay at their isolated cottage, next to a lake. It would be a weekend full of fishing, swimming and fun in general, just the three of us: mom, Suguha and me.
When we arrived at the small, wooden house, Suguha revealed she had a surprise for mom: a red bikini! At first, the older woman was reluctant, believing she was too old not to wear an one piece swimsuit, but Suguha was like: 'Nonsense! You have a gorgeous body.' My little sister had also bought a blue bikini for herself!
When I saw mom in bikini, I was awestruck. The last time I had seen her with so much of her body exposed was when I was a little child and we went to the beach as a family, but, of course, back then, I was too young to be interested in women in a sexual way. Not that, as a teenager, it was justifiable that I suddenly started feeling lust towards my own mother! Man, how weird can I get?
Anyway, apart from their house, those relatives had also let us use their fishing boat; even if we didn't catch anything, we'd enjoy a wonderful tour of the lake! And so, that Friday afternoon (we began our journey on Friday midday, right after mom had finished her work), here we were, enjoying a boat ride. Myself, I was fishing (not that I had much luck) while giving furtive glances to mom and Sugu, who were sunbathing on deck chairs, both wearing only their bikinis and sunglasses. Myself, I was wearing a white t shirt and black swim trunks. Mom was lying on her back, with one knee bent and the other leg crossed over it. Sugu was lying face down, one calf raised.
With a bulge in my swim trunks, I couldn't wait to get to fuck my sister again to relieve it. Of course, fucking mom was out of question. I mean, I had got in several weird situations over the last months, but I couldn't imagine what kind of series of events could lead to such a scenario.
It seemed our idea to use the autopilot wasn't very good after all. Soon, we felt great turbulence. The boat had just crashed against a rock! I looked at the large hole in horror.
Mom and Suguha ran to see what had happened.
'Bro, what happened?' sis asked, a little scared.
'Honey, what happened?' mom asked, sounding calmer.
'There is a giant fucking hole in the boat,' I declared, alerted.
'Kirito!' my mother snapped. 'I haven't raised you to use such bad language. You're grounded, sir!'
'Ground me later, if we're still alive,' I yelled to bring her back to reality. 'The boat is sinking!'
It was sinking indeed. Fast! Unless we did something, we'd soon end up along with it at the bottom of the lake.
'I'm scared,' Suguha cried, thus reminding me that she was actually still a kid, despite her physical development and sexual awakening.
Mom took charge. She looked at the water and sighed. 'Get ready, guys. We're diving,' she announced.
'But... but...' I didn't know what else to say.
'We have no choice!' she snapped. 'We're diving. NOW!'
And so, we did! We were now swimming in those hostile waters. Man, I had never imagined that a mountain lake can be so cold even in summer; the fact that the sun had started setting, which meant the temperature was falling, didn't help either.
When we managed to reach the bank, we all felt frozen. We looked around and realized we had no idea how to return to the cottage. We were lost!
'Mom, I'm scared,' Suguha said, hugging herself to warm her torso, tears in her eyes. But I was not really calm either.
Realizing it was her duty as our mother to cheer us in a moment of peril, she tried not to lose it as well. 'Come here. Both of you,' she whispered sweetly. She hugged us both simultaneously. 'Everything will be fine. I promise,' she said comfortingly, though I could tell she was not really sure.
We began walking, just hoping for the best. It was dark. The night mountain breeze was tormenting us. Past a point, I could not bear to see my two female family members suffering like that anymore, with only their bikinis on. At least I was wearing my t shirt, albeit it was wet. So I took off my upper garment and offered it: 'Anyone wants to wear it?'
'No, sweetie, keep yourself warm instead,' mom refused.
'YES!' Suguha snapped, grabbed it and put it on.
Although I could tell a wet t shirt did not really make much difference, my sis did not neglect to show her gratitude. 'Thanks, bro. You're the best,' she winked at me.
Eventually, we found an abandoned, wooden fishing cabin. 'We're saved,' Suguha cried. 'We won't freeze to death.'
'Everyone run in,' mom commanded, though that command wasn't necessary.
Inside, we found a lantern that provided us with some light.
'Search for anything that might help us warm ourselves,' mom instructed, bouncing on her toes because of being cold.
I found some magazines next to a fireplace. 'Hey, maybe we can burn th...'
'Eureka!' Suguha's happy cry interrupted me. She dragged a large sleeping bag outside of a cupboard.
'My heroine!' mom exclaimed.
Let's hope it would be large enough for all of us to fit in, otherwise somebody would have to sacrifice themselves and freeze to death to save the rest!
'Take off those soaked clothes of yours,' mom instructed. Normally, she's very prude, but that was an emergency.
I took off my swim trunks as my sister took off my shirt and her bikini. Soon, mom was left nude as well, her bun untied. For a moment, I revered her nude beauty. I had seen Suguha nude in the past (unbeknownst to mom of course), but this was the first time I saw my mother like that. Wow!
Suguha and I were the first to enter the sleeping bag. We were facing each other. Mom squirmed between us and, finally, after a lot of effort, she managed to fit in too, facing me. And so, we relaxed, enjoying the warmth generated by the close contact between our bodies, finally relieved that we were warm and would not freeze to death after all.
Inevitably, that close contact with my mom's nude body caused me a certain... reaction, which I could not hide under the existing circumstances.
'Kirito!' mother cried, shocked, my penis poking her leg.
'What happened?' Suguha asked, though, judging from her laugh, I bet she had a pretty good idea!
'I'm sorry, mom,' I blushed. 'It's just that you're nude and I'm so close to you and...'
'It's okay, sweetie,' she said, caressing me comfortingly. 'Just try to think of something else.'
'Heh. Easy for you to say,' Sugu remarked, eliciting a glare from the older woman.
Meanwhile, my penis, which would not go down a bit, felt like it was about to snap in half, having no room to extend. I squirmed in pain.
'Maybe it will go down if you just stay still, sweetie,' mom advised.
'It's no use,' I complained. 'It hurts.'
'Here, let me see if I can help,' she said sweetly, trying not to laugh.
She squirmed a little as well to give me some space. My penis ended up snuggled between her legs.
'Better?' she asked for confirmation.
'Better,' I sighed in relief.
However, as it turned out, that was not a good idea after all; now that my dick had more space, it grew... and grew... until it touched mom's pussy, the hole that created me!
That sensation, the sensation of my mom's vagina, on top of me having been close to hypothermia recently, blurred my reason; I no longer knew what I was doing!
Suguha's POV...
Mom's eyes widened in horror.
'Oh, shit,' she cried. 'That was a bad idea. Don't move, sweetie, don't move, don...'
But Kirito seemed not to be conscious of his surroundings anymore. With his eyes closed, he gripped mom's shoulders. Judging from the way he was moving, I could tell he was slowly driving his penis towards his mother's vagina!
'Kirito, don't move any further,' the older woman pleaded. But Kirito was in his own world at that time; there was no point in talking to him. 'OH, FUCK, it's in me!'
Kirito began thrusting! Mom tried to push him away, but there was no room for him to be pushed. 'I need to get out of here, NOW,' she cried as she started trying to squirm her way out of the bag, while the oblivious Kirito kept thrusting and moaning in bliss, his eyes closed.
'Hold still, mom,' I grabbed her by the shoulder (which my brother was already gripping), thus stopping her. 'It was really hard to get in here.'
'SUGUHA, are you nuts?' mom protested. 'Have you realized that your brother's penis is in my vagina?'
'Then just let him finish and it will go down,' I argued.
Mom was about to reply, but she stopped, unable to find anything to say. The next moment, she sighed, seeming to relax a little.
Eventually, she started enjoying it! This realization was a surprise both to me and her. My eyes bulged when I saw her starting to reciprocate!
She wrapped her hands around Kirito's neck. She was now thrusting against him as well. Their movements were synchronized. They were moaning. From time to time, Kirito would lean his head and kiss her breasts, thus increasing her pleasue.
Finally, it happened. Kirito remained stiff, his eyes still closed, while mom let out a scream. They were climaxing simultaneously! I was witnessing my brother fucking our mother!
Then... they relaxed. 'I can't believe I did this,' mom sighed, facepalming in shame.
Kirito opened his eyes, now back with us. His expression was that of a little child caught doing something mischievous. 'I'm sorry, mom,' he said with remorse. 'It just felt so good that I couldn't control myself.'
'It's okay, sweetie,' mom caressed him. 'It was just an accident. I mean, today, the whole universe conspired for all those coincidences to occur. Anyone would have got carried away too in our shoes.'
'Actually, we're not wearing any shoes right now,' I tried to draw mom's attention and playfully foot cuddled with her under the cover.
'Haha, very funny,' mom sighed. 'Anyway, time to get some sleep guys.'
And so, we said our goodnights and went to sleep. Soon, mom and Kirito were sleeping like logs. Well, that was not surprising, considering they had got off before!
But, myself, I hadn't gotten any relief of this kind. How was I supposed to sleep while still horny, and, on top of that, with mom's nude body in contact with mine making my arousal worse? That was not fair!
A mischievous smile formed on my face. I bet that, after all that stuff that had happened that day, mom would sleep heavily. So she wouldn't wake up if I got some... advantage of her to get my share of relief! It was only fair that I orgasmed as well!
I drove my hands undercover and started groping mom's back and ass. What a sensation. Meanwhile, she was sleeping peacefully.
I started planting kisses on her neck. That made her squirm and moan a little, but her sleep was uninterrupted.
Getting more 'ambitious', I started rubbing my pussy against her ass. I placed my hand on her shoulders, as my brother had done before, except I had to be careful not to use much force and wake her up.
I kept rubbing and and moaning, my mom and bro sleeping in ignorance. My boobs were being rubbed against my mother's back, increasing my pleasure. I moved one hand over her and managed to get a hold of her breasts as well. What a feeling!
Eventually, I cummed! 'Night, mommy,' I whispered, kissed her on her black, loose hair and went to sleep.
