Frustrated, you throw out a straight aimed for face. Riley is taken aback by this somewhat, so much so that that your fist connects. Staggering only slightly, she grins from ear to ear and raises her fists in turn.

Riley throws out a left hook, sending you reeling. You only have a split second to react before the next hit lands.
