As Evan was making his way through the tight space, he didn't realize the infant he was holding was actually draining Evan of his masculinity through his breasts. After crawling for almost a minute, the infant was now much heavier having aged to almost 4 years old. Evan didn't notice the changes but he himself was losing years to the infant - Evan was now only 20 years old as opposed to his original age of 23. Luckily Evan didn't change as much as the infant, only losing a bit of muscle and an inch in height. However, the loss of most of Evan's chest hair and treasure trail might be more noticeable had Evan been bare chested.
Unaware of the changes, Evan reached a new room and continued to let the infant suckle from his now hairless nipple - it felt pretty nice. Evan looked around and saw he must have ended up in the armory. The room was mostly dark, with beams of light coming from torches lit in the tunnels. These minotaurs were armed to the teeth with weapons and heavy armor. Evan realized that the minotaurs were prepared to wage a war soon; this sneak attack couldn't come later. Taking a short break, Evan fiddled with the armor and weapons, sabotaging their weapons and armor to fall apart when worn. Evan also poisoned a nearby food source knowing the minotaurs won't find out until it is too late.
With that being done, and the minotaur infant still drinking Evan's essence, the two had now aged to 7 and 17 respectively. Evan was beginning to struggle to hold the minotaur boy with his weaker physique and smaller stature. Evan now had lost all his body hair apart from light wisps on his legs and crotch with some peach fuzz on his face. His muscles were mostly gone now and he had shrunk to almost 5'5'' - it would be hard fighting an army of minotaurs as a teenager. Evan saw his changes and shoved the minotaur child away as he pulled out his daggers; Evan was having trouble holding his daggers in his normal pose due to their heavy weight.
The minotaur child stumbled back before looking Evan in the eye. Evan was unsure of what this beast would do next - first it stole his strength and masculinity, what now?
