Dale and his original trainer Samantha worked on a poke-breeder ranch, helping out with daily chores and duties. Feeling pent up, he decided to make "unauthorized use" of some of the ranch equipment while his master wasn't looking.
Dale has always had a crush on the Island Kahuna Olivia ever since he saw her visiting the ranch he grew up in on Akala Island. Doing something like this was always just a pipe dream fantasy to him. No human could handle a male like himself, let alone willingly, right? Guess being a tough-as-rock trainer has its benefits. Well it might not be exactly clear how they got into this predicament, but looks like somebody just walked in on the sweaty, steamy aftermath.
Great comment!
