By u/JoeHaydn, its the Vaporeon copypasta but changed to Cecilia from ZZZ.
Hey guys, did you know that in terms of male human and female thiren breeding, Cecilia is the most compatible thiren for humans? Not only is she in the field egg group, which is mostly comprised of mammals, Cecilia is an average of 5”07’ tall and 96.9 pounds, this means she's large enough to be able handle human appendages, and with her impressive Base Stats for HP and access to Acid Armor, you can be rough with her. Due to her mostly water based biology, there’s no doubt in my mind that an aroused Cecilia would be incredibly wet, so wet that you could easily breed her for hours without getting sore. She can also learn the moves Step-on-me-mommy, Baby-Doll Eyes, Captivate, Charm, and Tail Whip, along with not having fur to hide nipples, so it’d be incredibly easy for her to get you in the mood. With her abilities Lactation and Hydration, both you and she can easily recover from fatigue with enough water. No other Thiren comes close to this level of compatibility. Also, fun fact, if you h*ld her hand, you can make your Cecilia turn beet red. Cecilia is literally built for human intercourse. Ungodly defense stat+high HP pool+Acid Armor means she can take the mating press all day, all shapes and sizes and still come for more.
