Do you also know that in terms of male human and female Pokémon breeding, Vaporeon is actually not the most compatible Pokémon for humans? This is a common and understandable misconception, however Vaporeon has it's human on Pokémon 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 Pokémon. 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 Pokémon to breed with. It can learn Payback, which doubles in power after the Pokémon 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.
