You decide it would be best to attack from an angle that she can't bite you from. You run at full speed then launch yourself right at her. While you're in midair, she lifts her tail up and turns her head with a devilish grin. It's at this brief moment that you realize your mistake. Using your own momentum against you, she succeeds in landing you right into her tailhole. Your body is already halfway into hers with only your rear half sticking out. Although frustrated at yourself for your failure, you are enjoying the sensation of being in the warm wet hole.
Luckily, the other young pokemon ran away when the two of you started fighting. You were saved the humiliation of an exposed erection from being in a rear end that you actually lust for. Filo decides to finish the job while you were in that state by sitting down and forcing you in the rest of the way, letting out a howling moan that sounded like the voice of a divine legendary pokemon. You were ashamed and embarassed, but a part of you still craved more.
You could guess she could tell your desires when she finally speaks up "I know you like it in there, I sure do. I may have been betrayed by him, but now I know that true love doesn't exist. I'm just a big stupid fat arcanine. Well, you two are worse. You're only food now." You hear muffled crying in front of you. You almost forgot the two cubs are still in her stomach. This arcanine has lost it after being stabbed in the back.
You try crawling up her intestines, but they push you right back down and you realize you are powerless against her body. As you do you, hear giggling from your captor and more screaming from her victims. You could try pleasuring her from the inside so she doesn't run away and her parents stop her madness. Maybe she will be happy enough with just you and you could convince her to let them go and take off with you.
