M Tyrantrum x M Furfrou
Furfrou was travelling through the mountains when he ran into a huge creature - a Tyrantrum. He would've turned and run, but the sight he saw was more arousing than terrifying. The t-rex pokemon's 2.2m cock was out in plain sight, thick and rough. The mere sight made Furfrou's small 0.5m dick hard as he saw the giant cock before him.
The t-rex clearly saw this and instantly approached Furfrou, who turned around to expose his tight ass for Tyrantrum. Tyrantrum rammed about a third of his thick cock into the hole, causing Furfrou to moan in pleasure. He eased the rest in, causing a large bulge at Furfrou's front. He then pulled out all the way to the tip and forcefully slammed back in, repeating it slowly a few times.
"Faster...faster..." panted Furfrou, wanting more of Tyrantrum's big dick.
Tyrantrum nodded and began to pull in and out at a faster pace, his large balls slapping Furfrou's ass as the 1.19m poodle miraculously managed to take the dick over a meter longer than his own body. He moaned in pleasure again, raising his head to the sky and panting as the thick, lumpy cock fucked his hole.
"Faster! Harder!" moaned Furfrou, only for Tyrantrum to once again oblige and pick up the pace more, the slap, slap of his balls echoing across the mountain peak as he reached jackhammer pace. Furfrou moaned and screamed in pleasure as he came on the ground, the huge cock filling him with bliss and lust as it slammed him forcefully.
"More! Faster! Harder! Give me your all! Give me your best! Fuck me with all your strength! Don't hold back!" screamed Furfrou in glee.
Tyrantrum picked up the pace even more, his cock a blur and the slapping becoming so rapid it was almost a single noise as he pushed into Furfrou so hard he felt like he'd burst and slammed so fast a Deoxys-Speed would have a hard time matching the dinosaur's pace. Tyrantrum was like a wild animal, losing all control and fucking Furfrou ruthlessly as he screamed in delight and came on the ground again.
With a ferociously loud roar of pleasure, Tyrantrum sped up once again as his cock began to eject white cum into Furfrou's ass with the speed and force of a fire hose. He didn't stop pushing his dick in and out at extreme speed as he came, fucking his cum deep into Furfrou as he filled him with the warm liquid. He kept going for ages before he finally pulled out, cum spilling from Furfrou's ass as he let his new mate have a rest.
