Mirri smiled at Lyla as the girl arched, deciding now would be a good time to slide her fingers down the elf's body and gently rub against her sex.  She teased Lyla's outer lips through the thin fabric of her panties.  After a few moments however, she stopped, giving Lyla a kiss.  "Mm... I think your friend may be worried about you if we continue for long.  Maybe I should let you go back to her... and we can continue later," she offered, though the look in her eyes made it clear she wouldn't object to Lyla deciding to stay longer.
