It's Halloween, and the local park decided to celebrate with a bit of an unusual theme:
Baby Day At the Park, so all of the kids have to dress like a baby by at minimum wearing a
diaper and either having a pacifier or a bottle. Meryon and Addler are at the park celebrating Halloween together, and are running around playing Tag. Addler is "it" and is chasing Meryon trying to tag him. As Meryon is running, he has an accident and pees in his diaper, causing him to stop running. Since he is behind Meryon, Addler doesn't know why Meryon suddenly stopped running, but he takes advantage by tagging him, making Meryon now "it". Addler starts to run away, but quickly realizes Meryon isn't following. He looks back at Meryon concerned and sees him standing in a classic "need to pee" stance with a sad, embarrassed expression and watery eyes on the verge of crying. Realizing that Meryon is peeing his diaper, Addler goes back to Meryon to comfort him in his embarrassing time. As he does, he realizes his own need to pee, so in an act of friendship and solidarity, he decides to pee his diaper as well, so that Meryon wouldn't be alone. Stopping to grab the diaper bag, Addler guides a crying Meryon over to a more private area so they can change out of their wet diapers. Addler lays Meryon on his back
and strips him down to his wet diaper, which further embarrasses Meryon. But Addler points out his own wet diaper as a means of cheering him up. Meryon, surprised his friend would do such a thing to make him feel better, perks up immediately and launches himself into Addler, knocking him on his back, and simultaneously kisses Addler and reaches a hand into the diaper to grip Addler wet, stiff penis, catching Addler off guard.
