Akiko was playing Michelle's body like a harp, and how the girl moaned was proof enough of that.  The orgasm was explosive - but internally, lights multiplying behind her eyes as her brain flashed in ecstasy from all the hormones being released in her brain.  It was a good thing the privacy screen contained both visual and auditory dampeners...not that anyone would have complained about a moaning girl on New Year's, right?  Michelle's hands grasped at Akiko's head, pushing her muzzle into her crotch.
