Hehe, poor Octavia. She's probably wishing she never let Vinyl talk her into wearing a bikini to the beach. It must be so hard living with that silly unicorn!
Those must be some really powerful wubs to be able to cause her bikini vibrate like that and come off! Well, those are some mini bass cannons in the background and nopony messes with Vinyl's bass cannons!
Kind of a follow up to this pic I guess:
I guess Vinyl got Octavia to join and then turned up the volume which caused her bottom to fall.
Well played Vinyl, well played!
