The next day, Tiana overheard Dustin talking to himself in the bedroom next to his.
"Am I... thinner? Nah, I gotta be imagining things." He said.
"Perfect. It's starting." Tiana thought to herself.
She went downstairs for breakfast.
Her parents, June and Mark, were gleaming. They looked much younger and even healthier. June had gotten a lot thinner and so had Mark.
No one batted an eye at Tiana (Ty's) new body or their changes, at least not too much. Tiana was shocked at how amazing her new power was.
She went to school, noticing that the girl's were a bit older looking and a lot more developed.
Bridgette, an already bubbly, hot cheerleader, looked even better than usual. Her D-Cup breasts were now DD-Cups, and her hips were looking a bit thicker. The thing that shocked Tiana most was that she was acting much nicer than usual, even talking to a nerdier girl named Casey. Casey was looking a lot better now, too, her bit of baby fat having disappeared and her acne gone. She now had B-cup breasts where she was flat chested before.
Tiana also noticed that the men of the school were now a lot more timid and smaller; the jocks now looked to be about an average build, with every other guy looking very frail. The teachers were now also looking a lot younger, at least from their 50s down to their 30s.
Tiana smiled to herself; the virus was working, and no one had noticed yet! It was great.
She went through her day before heading home.
She decided to masturbate; she stroked her huge cock and played with her giant tits. Strangely enough, she also found herself shoving a dildo up her ass, realizing that she couldn't cum without it.
Eventually she came, a bit of shame washing over her as she tasted the jizz. Tiana hadn't tasted cum before, but she knew this wasn't what it was supposed to taste like. It was delicious to her.
"It must be the virus." she thought to herself as she went to sleep.
