Each gradual  progression into Fei's ass came with pleasured moans, the girl's ring providing to be more than a snug fit for her first time. Lily clings to Fei desperately as she enters, finally bottoming out with the girl's help, only to take a short pause, lest she cum on the spot...though it didn't seem like she'd mind that much, anyway.  With a light grunt, she uses her grip on Fei to push in just a bit, slowly pulling herself back before shakily pushing herself in, hitting a partial rhythm as she begins pounding away at the hole presented to her, slowly but surely increasing the tempo with each thrust.  Panting wildly, she decides that isn't enough, and mimic Emiko's earlier movements, strengthening her grip with one arm while the other finds one of her breasts, gently kneading it, firmly grasping it as she leans in closer still, practically pinning Fei down at this point. "I'm...I'm trying not to..." She pleads, slowing down to catch her breath before restarting the tempo, staving off an ending just yet.  She still remembers Emi's movements and techniques, and tries emulating them to an extent, each ragged breath meeting Fei's skin, full of lustful need.
