Hayle

Then I switched off the light, opened the curtain slightly to allow a little of the white glow from the streetlamp into the room, and got into my own bed.

Kai and Franziskus took ages to reappear. By the time they did, I was starting to worry that they'd had second thoughts and had decided to lock the bathroom door and have sex together behind it.

But after fifteen minutes they emerged into the bedroom with their towels around them, dropped them to the floor as soon as the door was locked and embraced in a deep and passionate kiss right in the middle of the room.

Then they climbed onto Kai's bed and hugged each other's naked bodies, whispering and chuckling between long, tender kisses.

Although my cock was raging at the anticipation of what was to come, I must admit that I felt a little uncomfortable watching them engage in what should have been a private moment. I felt guilty to be witnessing them whispering their affections to one another, caressing each other's bodies and masturbating each other's cocks. This was their moment; not mine. I guess it's odd that I felt like that, since I'd long-since had no reservations about spying on other men's bums and peering at their most private spots as they bent down, but I did. Maybe it was the fact I wouldn't have minded if some guy was getting off by checking out my arse, but I'd have been really pissed off someone was watching me making out with a girl.

There was a lot of cock rubbing between them, then they took turns sucking each other, and I saw it all pretty clearly thanks to the pale light coming in from the street outside. It didn't really turn me on, I must say, but it didn't repulse me either. It was curious to see two such well-built, apparently straight guys being sexual together right in front of me and a little odd to watch them being so tender and loving with one another's bodies. But at the same time it was good to know that guys could be like together, that we didn't always have to fight and compete with one another, and that sex between two men was as passionate and varied as the sex I was more familiar with.

When Kai got off the bed and fumbled around in his rucksack, my cock strained painfully in my hand at the realisation he was looking for a condom. It was oozing precum as it never had before; it felt like it was longer and thicker than it had ever been.

As he climbed back onto the bed and the two of them laughed at something Kai said, I was almost panting in anxious expectation.

The next minute or so was a little confused: their dimly-lit bodies scrabbled around as they squirted lube on cocks and into holes and adopted their preferred positions. It took me a that long to realise that it was Kai who was bending forwards on the bed, his face staring forward at the headboard, and Franziskus who was wearing the condom on his thick, arching cock behind him.

It took a couple of minutes for Franziskus to enter Kai: he'd push forwards but Kai would grunt and mutter something in German, and then Franziskus would withdraw, wait a few seconds and then try again. Perhaps this was the less usual position for them to be in; perhaps Kai was, as I'd surmised in the bathroom, more comfortable at being the dominant partner.

I wanted to be over there with them - to be kneeling next to their bed and watching Franziskus's large cock try to work its way into Kai - but I knew that I was so excited that I'd probably climax at the sight of it before I was even halfway across the room.

Kai let out a small fart and Franziskus laughed. Kai chuckled too and said something in German like, "Why do you have to be so big? You make it so difficult..." And Franziskus laughed again.

I took my hand away from my aching cock: I knew I would come right now, without even playing with it, if I kept holding it. Even the sensation of my duvet touching the swollen, throbbing tip of it made me wince in almost uncontrollable pleasure so I had to hold the underside of the bedding high above its engorged stem, feeling the tip gently oozing precum onto my belly in a continuous dribbling stream.

When Franziskus had managed to penetrate Kai, they began fucking in earnest. Franziskus's thrusts started off slow and gentle, but, at the encouragement of Kai who very quickly began to enjoy the attention his arse was receiving, Franziskus's rhythm increased until the two of them were panting and gasping and the bed-frame thumped against the wall.

I just lay there, as though hypnotised: my eyes wide and staring and my heart thumping in my chest. My cock throbbed above my belly, untouched, but I was unable to stop my hips from gently bucking as though I were imagining myself in Franziskus's place. 

Franziskus was making long, rapid thrusts in and out of Kai's arse. Every time he withdrew I could see his cock, slick and wet, emerge from his friend's round cheeks only to be pushed back in with a guttural grunt from its owner. He grabbed onto Kai's hips, holding the other man firmly in place, slamming his cock home harder and faster with every thrust he made.

I was unable to stall my orgasm any longer and it overwhelmed me right then. I could feel it building inside me but I found it impossible, no matter what repellent images I tried to summon, to quell. It rose to overtake me and all I could do was lie there and accept it: to try and stop myself from gasping as I felt my cock, still hanging untouched above my belly, squirting jets of hot semen against my teeshirt and skin.

After my cock had spent itself, I lay stunned and slightly bewildered by the intensity of my excitement and the force of my climax. I was dimly aware that Franziskus's rhythm was reaching a crescendo but drowsiness was rapidly washing over me. My chest was sodden with my cum but, since I was unable to clean myself up, I gave up to my sudden exhaustion and closed my eyes. The last thing I heard was Kai begin to gasp as he reached his own point of no return.

I was awoken early the next morning by the familiar sensation of guilt gnawing at me like a rat.

Why had I been so excited by the anticipation of watching the two of them having sex? Why had I climaxed so forcefully when I saw Franziskus fucking Kai? Why had I been powerless to think of something to repulse me like I usually did?

I lay in bed, unable to get back to sleep, wondering how things could have gone so far without me being able to stop them. The room grew lighter, Charlie started becoming unsettled as he began to wake up, and the sounds of cars outside became more regular.

I kept thinking of that toilet stench; the smell of the school loos. That's what guys' arses smelled like, didn't they? That what having sex with another guy meant having to push your cock into, didn't it?

This time the faithful and trusted weapon hadn't worked. The trigger seemed to have jammed or something. There'd been no stench when Franziskus had fucked Kai; there hadn't even been a whiff of anything unpleasant.

Maybe I'd been wrong; maybe gay sex actually wasn't that unpleasant. Maybe it was actually pretty good -

I cut that train of thought off before it could get a hold on me.

At that moment Charlie groaned as he stretched and then stumbled out of bed.

I looked over at the beds on the opposite wall; Kai and Franziskus's beds. It seemed that, after having sex, Franziskus had gone over to sleep in his own bed. Kai was alone, sprawled out, in his own.

I saw Charlie glance over at me out of the corner of my eye and I pretended I was still sleeping. He pulled a couple of things out of his bag and headed off to the bathroom.

The noise of Charlie getting up must have awoken Franziskus because he coughed a little and then climbed out of his bed. He walked over to Kai and shook him. Kai groaned and tried to turn over away from him. Franziskus chuckled and pulled away his duvet, saying something I couldn't understand. Kai groaned more loudly, protesting at his sudden involuntary nudity, and croaked, "Please," in German.

Then Franziskus picked up his things and went out of the room. Like Charlie, he threw me a glance but I maintained the pretence that I was soundly asleep.

Kai groaned again and turned over onto his stomach, clearly hoping to sleep on a little longer despite the lack of duvet, and his naked arse pointed invitingly upwards.

I peered over at it, fascinated by the knowledge that here was a freshly-fucked arse in all its glory, just a few feet away from me. Despite its exertions on the previous evening, my cock began to stiffen rapidly again at the prospect of getting a better look at it.

I got out of bed as quietly as I could, feeling my teeshirt snagging my skin where my dried cum was sticking the two together. After yanking my boxer shorts back up to cover my cock, I crept over to the bedroom door, which was half ajar, and listened to Charlie chatting with Franziskus in the bathroom along the corridor. They were far enough away for me to get a few seconds warning if one of them were to walk back towards the bedroom.

I pushed the door almost fully closed and walked over to Kai, trying hard to spread my weight so as not to make the floorboards creak.

He was breathing slowly and deeply, clearly soundly asleep again.

His arse looked even better up close: the cheeks were round and muscular and had parted just enough to reveal a little of his dark, slightly hairy crack. The lower half of that betrayed evidence of Franziskus's exertions on the previous evening: slick trails of dried lube were sticking the wiry hairs to his skin in clumps; a few faint pale brown streaks stained his skin around the area of his arsehole.

I thought, "Jesus - this is well and truly freshly-fucked!"

My own cock rose up to full size as if hoping to follow its predecessor in.

Underneath his arse, between the backs of his parted thighs, Kai's large balls looked heavy and swollen inside his loose scrotum.
