How tragically ironic. One of the few humans fighting against the Pan Virus contracted it at last.
Jack is scared and shaking and nervous and struggling to escape while Mark shoots his satryical load into his mouth. It tastes like ordinary cum mixed with the taste of the earth, that invokes a pastoral scene in Jack's mind. A scene of endless freedom, music, and hedonism. And through that scene all Jack can think about... is Dionysus...
Jack jolts back to reality as Mark and his cronies cackle a laugh infused with darkness. They stop restraining him and Jack tries to stand up. Then the changes finally begin.
A sudden rush of heat overcame Jack, like he was burning up from the inside. Pleasurable feelings started radiating from his groin as his cock started to tent through his shorts.
"It feels.. so hot... and so good.." Jack groaned. He tore his shirt off and stepped out of his shorts and began rapidly stroking his cock, moving his foreskin back and forth as the changes progressed.
His ears lengthened and pointed as panflute music came to his ears, seemingly out of nowhere. The sadistic song only made the longing in his dick grow stronger. Jack watched as the other satyr's started sucking eachother's dicks.. then the changes started to really accelerate.
"Ugh.. whats.. happening.. to meeee", Jack cried out as his legs bent underneath him. A sudden extreme itching sensation fell over his legs as thick dark brown hair sprouted out, starting from his pubic hair and gradually covering his feet. His toenail's darkened and grew out and hardened into a thick stony set of hooves. Jack's dick then changed as his foreskin started itching uncontrollably. The foreskin became covered in fur and then pulled back against his stomach, forming a furry sheath. The sensitive inner foreskin and glans shuddered, morphed and changed becoming a goat dick stretching out from his new sheath. Though his foreskin was changed into a sheath, it didn't take long for Jack to learn how to pleasure his new member, as it was even more sensitive than the inner foreskin and frenulum of his old dick.
"Wow.. why did I try to avoid this... This is all I've ever wanted"! Jack yelled as his spine lengthened and a short furry tail grew out. As his face pushed out ever so slightyl into a hybrid of human face, beard, and goat muzzle, Jack's hair on his head lengthened and thick horns pointed out of his skull.. completing the changes at last..
Then Mark said, "Welcome brother Jack, lets go transform the whole world! Let us spread the good news of Dionysus to the nonbeleivers and watch them squirm and struggle as they accept his sacred blood"!
