reese's pieces, buttercup...

The mother bear was faster than Jupiter had thought possible. She spun around after him and succeeded in spanking him on the rump. The blow was glancing - thankfully - but her claws left light lacerations down one thigh and drew a startled yelp from his lips. He yelled in a carefree voice that sounded a touch forced, "Easy, lady, there are better ways to get a feel!" That really fucking hurt, actually. He would have to have Darya look at them later and make sure he wasn't going to get an infection or anything stupid like that.

Jupiter ran directly from the mother bear to the "baby" one. If they took turns worrying them and running them in circles around each other surely they would tire quickly and give up the attack. That's what he would do, anyway, if he was a mother bear with a nearly-grown son who refused to give up the tit and required near constant attention.

As Natha evaded the male bear's jaws Jupiter found himself at the beast's rump so of course he tried to take a bite out of it. An ass mark for an ass mark. Granted, this mark was on the wrong bear but as they were a fighting pair it seemed reasonable to consider them a single unit.
