Consent is for the dull
Five college-aged guys share a house, and come to an agreement where consent isn't always necessary. This is a first-draft that needs proofing and, perhaps, a lot more added. It almost works at this length though, so I'm posting it as a flash piece, because there's a good chance I may not ever write the rest.
"Gotcha"
Jackson groaned, as the horse grabbed his butt, groping him hard through the denim. He stopped washing up, hanging his head. "Ah come on Jack, I'm going to the cinema in like 10 minutes"
"Not any more!" Blake crowed "You're all mine." He was stepping in behind the bunny now, moving right into his personal space and pressing his crotch against Jackson's ass. The bunny could feel Blake's bulge through two sets of clothing, Thick and aroused, the bay stallion was already hard. As Blake's hands reached around to grab Jackson's hips, the bunny knew it was hopeless, but still, he had to try. Switching off the hot tap, he looked back over his shoulder, and gave Blake his best wide-eyed, winsome look. "Pleeeeeeeease, let me off, just this one time, and I promise I'll make it up to you later!"
Blake just snickered and shook his head. "Oh no bunny. Somebody else can make it up to me later. You're gonna make it up to me right now. Rules are rules. And I wantsome bunny-ass."
Jackson just whimpered, feeling Blake grind at his rump again and again. He could smell the Stallion's arousal, and he wasn't exactly unaffected. He could already feel all the tension leaking out of him. The thought of 8 inches of thick horsecock pressing against his ass was heavenly, even if he was busy. And Blake was already working the buttons on Jackson's cut-off denim shorts. Those shorts were so damn tight, it felt good to feel them loosen. Jackson finally gave up, grinding his ass back against the big boy behind him, and leaning his head back to kiss the tender skin of the horse's muzzle. It wasn't like he wasn't going to enjoy it, after all.
It wasn't like he had much say in it, anyway.
The rules were simple, Jackson had agreed to them along with the rest of the guys. Inside the house, between the five of them, there was no concept of consent. Just want, take, and have. It had semed exciting and sexy, wild and free. It had felt like living one step removed from the normal bubble of safety and protection that modern living affordes. It it still did.
Jackson got the worst of it, of course. A cute bunny with a tight butt, at least a few inches shorter than every other guy in the house? and a preference for wandering around in nothing but a tight pair of really short denim cut-offs? Those shorts barely even covered his butt. So yeah, he ended up on the bottom a lot. Hell, in the first two weeks it had gotten so he could barely sit, but it had evened out. the two jocks in the house, Blake and the hyena, had started spending more time with Steve instead, A slender deer, the bookish type, Steve wasn't the type to flirt as hard as Jackson did, but he was sure a willing partner in the sack, and sluttier than you'd have thought.
So the jocks split their attention between the two of them, and occasionally challenged each other for dominance. It had been fun to watch Blake's eyes bug out the first time Brad, had hilted his cock in Blake's ass. The horse had been pinned down on the living room floor, lost a wrestling match to the hyena, and the whole house had stood on to watch.
But since those first, heady weeks, the novelty had worn off a little. Now there wasn't *quite* so much fucking, and they'd come to an understanding. No one got jumped anymore, no-one really fought back either. They'd made a game of it. You had to take the guy unawares now, sneak up behind him and grab his ass, before he realised you were trying to. Then you could have him.
Just like Blake had done.
