Yes, softly

The two humanoid pokemon went to Rose's den. It was a quaint cave, with some furniture made out of leaves, rocks, and soft plants. "You must have a thing for interior decorating." Ash laughed saying that, causing Rose to blush again, caught off guard from Ash's wonderful laugh.

They went to the bed where Ash gently pushed down the Gardevoir. There they were, the shiny Gallade on top of his Gardevoir lover, Ash's member extending, as he was looking at her breasts, and noticing her vagina for the first time. "Oh Arceus, you're seriously beautiful." He said looking deep into Rose's deep red eyes. "No one has ever said that to me. Thank you, Ash." Rose began to shed a tear, but it quickly dried out as her sadness turned into pure ecstasy once she felt Ash enter her.

The two felt pleasure like never before. Ash couldn't even believe he was having sex with a Gardevoir, let alone that he was now a Gallade. Rose, on the other hand didn't need to think. She just brought her mate's face down to her and kissed him.

Her hymen was pierced while they were kissing, causing Rose to moan in pain during the kiss. They separated their mouths at that time, Ash now holding his wife closer. "I'm sorry." He said with shame. "No need to be sorry, Ash, my love." Rose said, loving the warm embrace. "It's my first time, and my first heat, as well."

Ash didn't realize until now that his lovely bride would become pregnant after this, and now that he knew, he got more into it. "I want to have a child. I want to have an adorable Ralts." Ash said as he continued to pull in and out. "And I hope it will be soon." Ash was at his climax. "I love you, Rose. I fully accept being the father of your children." And with that, they both climaxed, the sperm flowing in and racing to the egg.

They both relaxed, Ash watching his beautiful mate begin to nod off. He pulled out, and held her close, both in compketw bliss knowing that they had each other.
