Just get away, before it pops, come on...
Squelch.
A noise somewhere between a hiss and a moan reverberated through the arachnogon's snout, air escaping the hybrid's nostrils. Salrith felt another heated inch of stiff, slick flesh sink into not just one but both holes. Struggling to reach for the book, the one thing that might help Salrith out of the whole mess, the hybrid felt a powerful throb inside as the beast pushed another spurt of gelatinous cockslobber inwards. The feeling of having those copious ropes of preseed pour into Salrith's vent from behind left the hybrid trembling and feeling warm. Clutching at the beast's forelimb, Salrith heard a menacing growl that wordlessly warned stop moving. The smell of sex hung in the air, and the scent of a potent, wild male was saturating Salrith's snout, slowly but steadily getting to the hybrid. This had been a grave mistake.

Feeling every twitch and every pulse of the beast's heart through the twin shafts skewering in under the hybrid's tail, Salrith felt stretched wide enough to ache. Every time it rocked its powerful hips forward, Salrith's vent and ass were spread wide around inches of greasy, plump cock. Every time it wrenched itself backwards, they would almost distend backwards with it, they were so full! The beast was enjoying every moment and seemingly had no plans to let free the easily captured female-smelling thing under it. Salrith had been foolish - having wanted to be closer to the beast, to mess around with the exotic creature - especially after seeing what it had packing between its legs. The hybrid hadn't counted on it deciding it wanted more than just a blowjob from the arrangement, and having the strength to turn the tables so quickly... It hissed in pleasure and humped away at the arachnogon, eager to spill its seed. If it hadn't had one heavy, wickedly-clawed talon clamped around Salrith's snout, the hybrid would have moaned. But if the beast spilled inside... Well, Salrith's ovipositors would be feeling it in a few days.

Salrith tried to squirm out of the beast's grip when suddenly something heavy and soft bumped against a kick. Leathery, plump, warm... and eliciting a deep, guttural growl from the beast as it was touched. The beast's other forelimb curled around Salrith's neck and chest before it tugged itself backwards a few inches. Salrith was almost heaved backwards with it by the sheer size plugging both holes at once, and the hybrid felt the thing against one foot swing. Salrith felt almost faint, realising that it was one of the beast's balls. It had to have gallons stored up! Then the beast wrenched the hybrid backwards, sheathing a half dozen more inches of slimy, veined flesh in Salrith's stinging ass and vent, squashing both ovipositors down in their fleshy home. The arachnogon saw spots and couldn't stop from clamping down around the fat, dripping spires that were steadily trying to both hilt.

Saliva spilled from the monster's toothy snout as it squeezed the arachnogon to its chest, and Salrith saw its jaws part. If Salrith knew beasts, then it was getting close... And so was Salrith. The arachnogon had to pull off now or there were going to be fertilised eggs to--
"MMNPH!"
Knots?! Salrith's legs nearly gave out, suddenly realising the beast had some sort of knots near the tips of its gut-stretching cocks, and they were swelling. The arachnogon's eyes snapped wide open, beginning to thrash, tugging and squirming as Salrith's walls began to stretch. The beast snarled and hammered itself in and out of the arachnogon under its broad chest, bludgeoning its suddenly bloating tips into Salrith. Suddenly frantic, Salrith began to writhe under the beast, trying to pop off before the beast finished. But with the size of its cocks to start with, knots made it all but impossible, and squirming only sealed the arachnogon's fate. Salrith gazed up at the delighted jaws of the beast as it slowed for a moment. A heavy pair of throbs wracked Salrith's ass and vent, and then the first almost scalding jets of cum flooded inside. Salrith felt each spurt as the beast rocked back and forth, knots swelling bigger and bigger. It came like a firehose, and Salrith felt a wet splurt of slime spray out from around both of them and splatter the ground once, twice-- then stop altogether as the beast's knots sealed the rest of its custardy spunk inside.

Salrith groaned loudly and flexed both mandibles as the surge of warmth began to slosh deeper in. A pressure built against Salrith's insides, growing almost painful. With nowhere to go, the beast's beachball-sized balls began rounding Salrith out, leaving the hybrid shaking in its grip. Just when the pain began to threaten to overcome the pleasure radiating out from under Salrith's tail, a soft gurgle squelched out and the beast's slime finally breached and began to flood into Salrith's womb, deep inside, while the rest surged deeper and deeper into the arachnogon's guts. Salrith could feel it, there was so much! The hybrid's eight eyes flickered closed, nostrils flaring. Fuck... No sense fighting it now...
With Salrith's own edge building with every copious, bloating spurt, Salrith pushed back against the monster and squeezed. Even as the hybrid did, Salrith felt the beast growl and begin to hump almost painfully forwards again, both making it clear it was far from done with just one round and forcing a muffled moan from the arachnogon. Salrith wasn't going to fight that anymore, though. If the arachnogon was dealing with a clutch anyway... well, Salrith was at least going to make sure it was a big one.
