Jeff watched Kyle prancing over to his family, knowing some more changes he'd set up on timer were coming any second now.
Kyle squealed like a girl when he saw his family, and raise his hand waving to get their attention. In that same moment, Jeff saw one of the changes take place - bushes of armpit hair grew out right when Kyle had his arm up, but they were so thick and full even the arm that was down had hair poking out the front and back.
Kyle suddenly started feeling so horny it was hard for him to think. He became more sexual and it was impossible for him to not be sexual in everything he did now, it came so naturally, anhancing his gayness 100-fold. The guys couldn't imagine Kyle acting more gay or feminine, but they were all stunned at how much more was possible. Jeff just smiled, enjoying the unfolding changes happening to his boi-toy.
At the same time as all of this, the stubble on on Kyle's chin grew long, hanging down now between his practically non-existant pecs. It wasn't a full beard, the hair tapered - chin the longest, and shortening rapidly til it was just stubble on the sides and above his upper lip. It was at this moment that his family saw him, witnessing the changes.
Being behind Kyle, Jeff saw the new tramp stamp appear above Kyle's ass - "THIS PUSSY IS PROPERTY OF MASTER JEFF". Then Kyle's IQ took a steep dive, and while no one could point out any specific changes, it became obvious in so many little ways Kyle was a complete airhead.
The last change was Kyle's name, it was changed to Princess and everyone would remember his original name but everyone would call him Princess. In fact, Princess's full name now was "Princess Cocksucker". And boy was it descriptive!
Princess pranced over and hugged his family. They seemed embarrassed by him - especially is brother, but Princess was oblivious, going on about what a wonderful day it was and how much fun he had sucking his boyfriend's cock last night. His father got red in the face, and excused himself to use the facilities.
"He wath tho amazing, hith cock felt thoooo good filling my tight puthy," Princess prattled on mindlessly, starting to feel a tingling deep inside himself. "OMG, I jutht LOOOOVE thucking hith cock, itth thooooo big and hard and thoooo hot! I jutht LOVE being hith little cockthucking bitch!"
The final changed happened, and even Princess herself noticed this one right away...
