Steve was proud of the way he’d arranged his class schedule. Everything on a given day was a short walk from the previous class, so, as usual, he was the first to arrive in the empty classroom. The lithe snow leopard set his laptop bag on the table at his preferred spot in the back of the room, and stretched for a moment. It felt good to stand a bit between long stretches of sitting.

A noise to his side caught his attention and he turned questioningly. He was sure the room had been empty, and when he checked, it still was. He shook his head, convincing himself he’d just been imagining it, but then a sudden weight landed on his back. Steve yelped as small hands gripped his hair, and he fearfully reached behind him to grab--

Eh, he could deal with whatever it was later. There were much better things for him to do. For example, his pants were feeling awfully restrictive. He would feel a lot better if they were off. He sighed happily as he dropped them to the floor. His boxers followed a moment later, freeing his erection, which was already dripping pre at the tip.

Steve didn’t know what had gotten him all worked up, but no worries, it gave him a good way to pass some time. He reached down and started to stroke himself, groaning at the extra sensitive feeling.

Had someone just come in the door? It sounded like someone had entered and started to yell indignantly, but it was quiet now.

He mewed softly as he pleasured himself, stopping only when a new idea popped into his head. What he really needed was a dick to suck. Wait, what? He’d never even been near another dude’s dick before, and he had a girlfriend waiting for him after class. That wasn’t usually his idea of a good time.

Still, just the thought of it made him drop to his knees. Steve almost yipped with joy when a cock appeared in front of him. He was dimly aware that there was a whole male attached to it, but that was irrelevant to his current plans. All he could tell was that he was clearly dealing with a canine of some sort. The other male was also highly aroused, and Steve could smell the heavy male scent wafting off the large red cock.

And then his mouth was around it, licking up the salty pre, covering the entire length with his saliva. He heard moans, but they couldn’t be his because his mouth was too busy coaxing more delicious pre from the tip of the thick canine length. Though he had never done it before, he managed to take the entire thing in his mouth, burying his nose in the canine’s pubic fur, the large cock tickling the back of his throat and mysteriously not triggering his gag reflex.

Sucking the mysterious canine’s dick was more fun than Steve would have guessed. He loved feeling it twitch and harden further as he licked across it, teasing the tip with his tongue. It was almost like he could feel an echo of the pleasure he was giving.

But as much fun as that was, Steve soon knew it was time to do something else. He let the slippery cock fall from his mouth, missing it for a moment as he stood and faced the desk he had left his bag on. His legs spread wide, he bent over, resting his upper body on the table. It was actually quite comfortable, even with his tail pulled to the side.

At first, something didn’t seem right when her felt the pointed tip of the canine’s cock pressing against his tight pucker, but when he suddenly relaxed and let the other male start to slide in his worries disappeared. His nerves lit up with pleasure as he was slowly spread wide, losing his anal virginity to another male and loving how great it felt. This time Steve could moan, and he did so loudly, arching his back in pleasure as he pushed back against the canine until the cock he had lubed with his own saliva was buried to the hilt inside him.

He squeezed down as he was filled, feeling pressure on places he didn’t know could feel such things. As great as it was, he wanted more. He got it when the canine started to move inside him, going straight to powerful thrusts. The other male must be just as aroused as Steve was. He could feel his own erection bobbing in the air as every hard thrust connected with his toned backside, his own arousal dripping to the floor.

The snow leopard bent over further, finding an angle that let the canine press against an especially sensitive spot deep inside him, mewing softly every time it was contacted by that pointed tip. His hands gripped the table tightly, tail lashing against his legs. He eagerly moved backward, trying to impale himself ever deeper on the thick shaft spreading him. The canine’s hands were on his hips, pulling him along as he got fucked, both males’ heavy balls jostling each other as they met at the end of every thrust.

Eventually he felt a swelling at the base of the canine’s cock, giving a little bit of resistance each time it slid into him. Every thrust it got a little bigger, eliciting a gasp from Steve as he was stretched further on each pass. It finally got through his sex-addled mind that it was the canine’s knot, and it might be a bad idea to let it--

He was overcome with curiosity. Suddenly he had to know what it felt like to have that full knot inside him, locking him to the male atop him. The idea felt almost foreign, but that made it no less compelling, and he cooperated gladly as the widening cock was hilted within him once again. The thrusts started to come shorter and faster, the canine pulling back just enough to tug at Steve’s sensitive ring with his swelling knot then slamming back in, shoving the feline forward on the table.

Then Steve got his answer, as the canine buried himself deep and held the snow leopard there, grunting as his knot fully inflated, stretching the feline’s virgin rear more than ever as he fired shots of cum deep into Steve’s bowels.

The snow leopard instantly reached his own climax, like it had been held back by some mysterious force that now released him. His rear clamped down on the canine’s cock, pressing the large knot solidly against his prostate. His legs went weak as he started to spurt, shooting his cum into a growing puddle on the floor, each shot accompanied by a tensing of his muscles that stimulated his sensitized nerves.

And still he felt the canine twitching inside him, releasing seemingly endless waves of cum, until he felt it start to leak from around the knot and drip down his thighs. He would swear nobody could orgasm for so long, but then another wave of pleasure rippled through him, making him call out and release again, his still-hard cock spraying his own renewed reserves of cum in front of him.

When at last the chained climaxes ceased, and he felt like his thoughts were his own again, Steve was wiped out. He sank against the table, partially held up by the canine tied with him, the cock in his ass still feeling better than he ever thought it would. He dimly felt some disgust at what he had done; he wasn’t gay, but he had submitted eagerly and let another male cum inside him. But it had felt so good, it couldn’t be that bad, right?

And then he looked up and saw the audience he’d had for the last several minutes, as the rest of the class started to show up. He hadn’t simply had sex with a guy, he’d done it in public as well. As he was stuck to the canine-- another classmate? He was afraid to turn and look --he couldn’t even pull his pants up. How could he explain what had happened when he didn’t even understand himself?
