Musubi came over to the seat.  "Pardon me..."  She uncrossed Elisabeth's legs and gently pushed them apart, before turning around for her back to face Elisabeth.  She then sat in the space that she had created, and leaned back against the mage woman.  "Okay, there we are..."  Settled together on the seat like that, Elisabeth would have prime access to just reach around and be able to have some fun with the catgirl's boobs...or a couple of other parts, if she so wanted.
