Juvia/Erza farts loudly

As Juvia/Erza charged, she suddenly stopped and held her hands over her skirt-clad butt. Erza/Juvia and Lucy heard her stomach growl as she bent over in pain.

"What's wrong with this body?" Juvia/Erza said as she let out a long five minute fart that rivaled that of Erza/Juvia's earlier one. The stench was unbearable as all three of them turned green from the stench. All the while, Juvia/Erza blushed heavily, in shock that all of this came from her butt. As soon as the fart ended, she collapsed to her knees in embarrassment.

"I'm so sorry! I don't know how that happened!" Juvia/Erza said frantically.

"Oh, yeah. I forgot about that weird cake Natsu gave me last night. I guess he spiked it with something." Erza/Juvia remarked sheepishly.

What now?
