Rika saw her petfuck's envious and soulful look at her and at what she was doing to her former poor partner.  The silver-haired kittengirl slyly grinned, gladdened by that reaction on Izuna's face.<em>"Don't worry my little traitor, you'll soon be joining her as well."</em>Her other hand circled about behind Yuka's wiggling strung-up petfuck, rough grabbing one of the buns of her cute behind before giving it one good hard slap.  But that was not end of it as Rika inserted her forefinger into the helpless girl's butt hole and begin roughly hooking it inside her.  "Why are you here?" she asks again.  "Who sent you?  Does you mistress know of this? Or," She began violently finger fucking into her rectum.  "Did Yuka put you up to this?" she sneered.
