The night was mostly quiet, with only the muffled sounds of creatures in the distance. Not a single being dared step close to Isaac's camp during the night thanks to his ward. However, the vines left an impression on Isaac, and had begun to change him with their infectious venom.
Isaac awoke to the usual morning wood. Ignoring it he got up and drank some water and ate some rations before donning his armor. Isaac's cock was a respectable 5 inches erect, but his dick was standing at almost 7 inches this morning. Such a change was subtle to Isaac, who paid no mind to it. However the growth of his cock was due to the vines from his previous encounter. Isaac had been corrupted by the plants, initiating a slow process that would overtake Isaac in due time if left untreated.
Despite the urgency of Isaac's condition, he shrugged it off and began for the crypts, moving past the half way point on his adventure. Isaac kept a cautious eye as he moved, careful not to get caught in another trap like he did with the vines. His flaccid dick was larger in his pants, and was leaking a bit of pre-cum at a constant rate. Isaac ignored the change and attributed it to the humidity making him sweaty under his armor.
At Isaac's current pace, he predicted his next break would be at the entrance to the crypt, assuming he doesn't run into trouble along the way.
