I Go on an Adventure to the Jungle with My Shy Stepsister and I End up Fucking Her Hard and Cumming Hard in Her Mouth

While I'm going with my shy stepsister on an adventure to the jungle and the river I feel like going to pee and something strange stung me on my penis and my shy stepsister doesn't know what to do and in order to get the poison out of my penis she ends up sucking me very hard until she gets all the milk out of my penis
