The zebra is done for the moment, and then she gets off you. She then commands "Trip to your undergarmets and relive yourself, Human". You have had to go for a while now, so your bladder and bowels are full to bursting. Forces start to make take your pants off and drop a load in your tighty whities. The zebra laughs, entertained by your wet and soiled underwear. You wonder what humiliation you will have to endure now.
