We had a few more beers. By now it was late. I announced that I was going to bed. I went to the tent, which was very hot inside, and stripped to my boxers, before climbing into my tent. It was pitch black inside. I was soon asleep and didn’t hear the girls coming to bed.
What woke me up was a hand straying into my sleeping bag. It was so hot I hadn’t zipped it up. Still feeling groggy and barely awake, I felt the hand slide down my stomach towards my boxers. I opened my eyes but it was so dark I couldn’t see anything. The hand then slid inside my boxers and before I had time to react was touching my cock.
My immediate reaction was to push it away, but in truth a lack of sex lately, the heat and the conversation outside, as well as seeing the two girls in their bikinis, meant I was feeling horny. Not only that, but it felt nice having a hand on my cock.
I quickly stiffened and the hand began to stroke me. I shifted my leg and pulled the sleeping bag down a bit.
Who was it? It had to be Emily. I couldn’t imagine my sister doing this. Emily seemed to have been flirting with me a lot during the day, although my sister had also revealed a side to her that I didn’t know, but my bets were still with her friend.
It felt amazing. I still had no idea who it was, and I was still turned slightly away from whoever was doing it. I guess the other girl had no idea what was happening, probably still asleep. It had to be Emily. I had to admit as the day wore on I was finding her more and more attractive. Her long legs, firm ass and tits, her eyes, her dark smooth skin. But to my shame I also found myself getting turned on by the idea of it being my sister. A handjob from your sister, was anything as dirty or wrong or hot as that idea. I rolled onto my back and slipped my hand across. I felt bare skin. I felt the soft flesh of a stomach, sliding down to the firmer touch of a pelvic bone. I slid my hand upwards and finally found a breast. A nipple. A slight moan drifted from the mouth of whoever had her hand on my cock. I edged across and began to lick, then suck the nipple. More soft moans. I didn’t know either girl’s body well enough to guess whose nipple I was sucking. I was getting closer to cumming. I edged further across, my hand now exploring the body next to me. She was naked. I found a neat trim of pubic hair, and then a wet fold of flesh. I slid my finger further, slipping inwards. Another moan. I moaned myself as my own orgasm neared, reprimanding myself for making a noise that might wake the third person, if indeed she was asleep.
Too late, I was cumming. Several jets of semen shot out, across my stomach, the hand that caused this, and the sleeping bag. My own orgasm complete, I fingered the girl to her own climax. Her ability to keep quiet was admirable. When we were finished, she rolled over to cuddle me, her breasts pushing against my back and we fell asleep.
I woke up to find the tent empty. I pulled on my boxers and stepped out. Both girls were sitting outside the tent, dressed almost identically in crop tops and shorts, eating breakfast.
“Morning sleepy head. Good sleep?” asked my sister.
“Mmm… not bad. You?”
I looked closely and suspiciously at the girls, trying to guess my night time’visitor’. My eyes drifted towards their chests, noticing that neither was wearing a bra and their breasts seemed of similar size, without checking more closely.
They both acted normally and eventually I decided to try to act that way as well, as neither was giving the game away. We planned a hike in the morning then swimming in the lake later. By the time we set off it was almost lunchtime, the girls having changed into their skimpy bikini tops and denim shorts. On the trail we passed a group of men, maybe aged in their early forties, who glanced admiringly. We stopped at the top of a ridge to rest and look at the view. The girls giggled.
“Are you enjoying the trip so far?” my sister asked.
“Yeah, it’s cool.”
“We’re not annoying you too much?” she continued.
“No not at all. You’re fun to be with. Besides, how can you be annoying, you’re my sister?”
“Are we more fun than you thought?” asked Emily.
“Definitely,” I replied.
“In what way?” Ava asked.
“Just….. fun.”
“Have you ever cheated on you girlfriend?” Emily suddenly asked.
“What makes you ask?”
“Just wondered.”
“Not that it’s any of your business but no.”
“Cool.”
“You’re so random,” I laughed.
I sat on a rock while the girls chatted to themselves.
“We passed a pool on the way up. We fancy a swim. Do you want to come?” my sister asked.
“No I’ll walk down with you then I’ll go back to the tent.”
“Ok.”
We walked together to the pool. I needed to do something so I was going to go back and jack off. Being with these two teenage girls was killing my balls. Sure one is my sister but fuck they’re just driving me crazy. God knows what my girlfriend Hannah would think but I have no intention of telling her. And last night. That handjob and bringing one of them to a climax. Oh fuck! I still have no idea. For my own hopes of going to heaven when I die I pray it wasn’t my sister.
Then a better idea struck me. Rather than go back I could spy on them in the pool and jack off there. I crept back up the trail. I found a perfect spot, where I could see and hear them, without being seen or heard. Also there was a possibility that they were both in on last night’s activity and I might discover the ‘culprit’.
To my delight, when I settled into my vantage point, I discovered both the girls were topless! Oh shit! They were splashing around in the water and occasionally I caught a glimpse of breasts. Then they climbed out and sat on a rock together, drying in the sun.
Emily’s black breasts were stunning. As previously noted not big, but just enough to cup. Her nipples were pointy and hard. My sister’s tits. Oh fuck, did I just say that? My sister’s tits, well I mean when did she get tits? When did that happen? Did I really not notice. Because like her friend’s, they were a thing of beauty. A very similar size. Almost identical. Perhaps not so pointy. But still hard nipples. I tried to think back to last night. I had a hand and a tongue on one of those tits, but try as I might I couldn’t remember enough detail to say which one. In a court of law, if pushed to decide, I think I would guess at Emily. But I could be wrong.
Their conversation was dull, not talking about anything interesting to me, and not mentioning me. Not that I am self obsessed but I was hoping they might drop a clue about last night. The only thing that really interested me was that my sister announced she really wanted to try skinny-dipping, and they both wondered if they could with me around.
“You can do anything you want if I get to see your sexy naked bodies,” I thought to myself.
I jacked off, watching them, staring at their boobs. Then as they were about to leave I hurried down the trail before them.
After we’d rested after our hike we all swam in the lake, although there was no suggestion of skinny-dipping. Maybe I’ll have to suggest it, perhaps tomorrow.
We had dinner and chilled by the camp fire, drinking beer and talking, mainly about music and movies. It seemed they’d calmed down from the silliness of the previous night.
Whacked, I went to bed first. I stripped to boxers and lay on my sleeping bag as it was so hot. Again I fell asleep almost immediately. All this fresh air! I didn’t hear the girls come to bed.
As with the previous night, it was pitch black in the tent when I woke up. I felt a hand on my stomach, sliding down towards my boxers. Then it slid back up and played with one of my nipples for a while. As whoever was doing this did it, she moved closer to me and I felt a pair of breasts pushing up against my back. She’s horny tonight, I thought to myself. Then her hand moved back to the band at the top of my boxers, under and in. She stroked my already hard penis along its length. She gently felt my balls before tightening her grip and stroking me. I helped her by pulling my boxers off.
After a minute or two I rolled onto my other side, facing her and began to explore her body. Like last night she was already naked. First her breasts then my hand worked its way down between her legs. She moaned slightly as I touched her wet pussy lips, and sucked on her titties. In a break from the previous night, I broke away from her breasts and kissed her face, first her forehead, then her cheeks and finally her mouth. I still had no idea who she was, my sister or her best friend, and so far nothing had revealed her identity, not even her gentle moans of pleasure. So perhaps exploring her mouth might give me a clue. It didn’t really, but I was still convinced it was my sister’s friend. I still couldn’t imagine my sister behaving in this way, even though I had realised this trip that she wasn’t the sweet innocent little girl my parents, or I for that matter believed she was. Still though, she wouldn’t indulge in mutual masturbation with her brother in a tent!! Would she?
Whoever it was, I made her climax with my fingers and then I came not long after. We fell asleep, still naked, in each others arms.
A few hours must’ve passed before I was woken again by a hand exploring my penis. In my sleep I had rolled over and now had my back to my seducer. As I opened my eyes, two things slowly crept into my state of awareness. One that it was light, the early morning sunlight streaming into the tent.
