The humming still coming from her vocalizer was twisted into a surprised - if pleased - gasp when Optimus angled his fingers against the thinner layers of plating on the hip-joint-side of her interface paneling and shocked her.

"Ah! You learn... mm, fast, Optimus," Elita said, static fuzzing her laughter as she arched again, drawing back her leg slightly to hook it about his waist instead, sending oil outwards in waves.
