Emiko's moans and growing arousal only fueled Becca's movements.  She moved her finger faster over the little nub and then thrusted her tongue in more.  After a few more seconds, she scooted up and then reached over into her bag and pulled out the strap on.  She slowly slipped the harness on before adjusting it and getting lube.  She slapped it softly across Emiko's pussy lips a few times before nibbling on her chest between her breasts.  "Mmm i'm going to enjoy fucking you...all those sounds..then licking you clean...mmmm"  she took off the nipple clamps and then swirled her tongue around both of them before teasing Emiko's clit with the dildo attached to the strap on.
