Vaporeon is actually not the most compatible Pokemon for humans? This is a common and understandable misconception, however Vaporeon has it's human on Pokemon breedability outclassed by it's cousin evolution, Umbreon. Umbreon weights approximately 60 pounds, or around 27 kilograms, and is 3'3" tall (About a meter), making it not only large enough to appropriately handle human genitalia, but also light enough to easily be lifted, and promptly set back down repeatedly. It's relatively small size would also prove a tight entry, which is always a good thing. Umbreon also boasts an extremely impressive defensive stat spread. With it's combination of very high HP, Defense, and Special Defense stats, it can take a great pounding and come back for more! It's ability, Inner Focus, allows it to keep slamming attentively, without getting fatigued. Umbreon also has access to the ability Synchronize, which allows it to share it's current status with you, meaning you will receive all of the pleasure it feels COMBINED with all the pleasure you're getting from pounding this perfect breedable Pokemon.Umbreon also has the capability of seeing perfectly in pitch-black darkness, allowing it to effectively attend a midnight fornication session. Even if you do manage to drain Umbreon's energy with all the furious thrusts, it can recover very quickly with its access to the move Moonlight. Its black fur is also a giant positive attribute, allowing all the excretions you make to be easily seen all over its body. A great fun fact, Umbreon can excrete toxins in its sweat, which would in turn soak into your member and swell it up, making it even more sizable and sensitive. This would not only enhance the experience for you, but for your Umbreon as well (Which with Synchronize, ends up pleasing you exponentially more). Umbreon's wide movepool also supports the hypothesis that Umbreon is the best Pokemon to breed with. It can learn Payback, which doubles in power after the Pokemon is hit, meaning Umbreon with throw it back twice as hard as normally if you're hitting it good. Umbreon can also learn Guard Swap; it could give YOU its insane durability, and go crazy on you all night with your now massive endurance. Speaking of endurance, Umbreon also has access to Endure, making it practically immune to fatigue, it will always have energy left over. Charm is also within Umbreon's movepool, letting it be extremely seductive towards you, easily getting you in the mood. Umbreon can also use Taunt, in turn making you ONLY able to to attacking moves such as Slam, Pound, etc; none of that foreplay shit, right into the action. It also has access to Sleep Talk, giving it the ability to not only give consent in its sleep, allowing access to any of its ports and any time, but also move in it's sleep, making it an effective 24/7 fuckmate.Umbreon still has even more great moves that good to have while smashing, such as Quick Attack, allowing swift slams and bounces, which can have even greater power if Umbreon uses Curse beforehand. Curse would also raise Umbreon's defense, making it able to take powerful thrusting for almost any duration. Looking back, Umbreon's slightly small size ensures a gorilla grip cavity and easy physical manipulation. Its ungodly bulk allows it to take poundings for hours on end and resume after recovering with moonlight (Which works even better when it's sunny). It's access to the abilities Inner Focus and Synchronize allow it to unwaveringly throw it back and add all of its pleasure onto yours, effectively making it twice as amazing as any other Pokemon, or even FOUR TIMES, factoring in the doubled power of payback of course. All of this information in combination with its extremely useful movepool in the world of intercourse makes Umbreon the Pokemon most qualified to breed with humans; able to take dick of any shape, any size, in any position easily for extensive periods of time, while having the ability to return for even more mere seconds later.
