Lets go for it.

Resigning yourself to whatever would come from your decision, you decided to roll the dice and go for broke. As you spread the magikarp's ass cheeks apart, and gazed at Maggie's puckered asshole, you had to admit you were a bit excited. Partly from the thrill of the challenge, but also because you were about to fuck another pokemon in the ass. The taboo act of defeating a pokemon with anal had become like a badge of honor to you

You lined up your cock with Maggie's tight entrance, and steeled your will for what would come next. Then you thrust your cock deep into Maggie's tight asshole.
