A lone and weary adventurer finds himself lost in the middle of nowhere, and with no choices left, he goes to rest at the base of a tree. Unbeknownst to him, the tree is actually home to a pair of mud girls who require a certain "toll" in order to rest at their home. Over their many decades of existence, the twins have come up with many intricate and exotic ways to go about collecting this "toll" - such that any who are subject to it are quickly won over by their skilled ministrations. Their signature technique involves one of the twin girls encasing themselves - literally using their entire body to wrap up another person - and then allowing that person to jack off and cum into the mouth of the other sister. All the while being coated in a taut and enticing layer of skin-tight mud.
