His muscles start to grow

As cum was released into Tom, John started to grunt and groan, because his cumming wasn’t stopping. He could feel a change to his muscles, starting with his groin his cock grew longer and thicker and his balls started to grow to the size of tennis balls then to the size of grapefruit, the growth moved to his abs, with a solid eight pack forming, his pectorals grew out of proportion with his nipples starting to release a sticky white substance, like his cum, which was dripping onto Tom. His biceps and triceps filled out, and finally the muscles in his legs grew out finishing the growth.

John suddenly knew others needed to feel this, to spread this. He look down at Tom, and saw he wasn’t far until he became like me, He looked at him and one word came to mind mate. Now he had a choice finish turning his mate or call in two males for them to turn, if he continued with his mate, he would start growing, or if he could get two males in here and enjoy watching his mate succumb to the need to fuck, along with seeing two males being infected.
