"Ty, wait!" Eileen said insistently. A pang of shame ran through the young woman- was this too far, too much? Did she need to turn them back? Obviously she could and would, but... it felt like it'd be a shame. Eileen was so hot like this, and she liked how a female body felt a lot.
"You know how you said you made Dustin younger? Do you think you can make people older, too?" he asked.
"I... I guess so?" Ty replied, still unused to her softer, higher-pitched voice.
"Well, do you think you could age yourself up? I don't wanna fuck you at this age, it seems wrong," said Eileen shakily.
"So... if I'm older..." Ty's voice trailed off as she saw Eileen nod, smirking. Once again, she practically commanded her body. I want to be 10 years older. An intense shiver ran through her and she felt herself growing and maturing. She gained an inch or so, still shorter than when she'd been a boy but not as girlish. She felt her curves fill out more, a soft pert ass forming with child-bearing hips.
Her chest swelled and firmed up slightly, giving her mature C-cup breasts that were clearly developed. Her facial features also firmed from immature roundness to mature womanly features. She heard as she breathed deeply how her voice was now more assertive- she was a woman and not a girl.
Eileen stood up from the couch and cupped Ty's cheeks, pulling the young woman into a firm, lustful kiss which she eagerly returned. Once they finished it, he whispered, "You're perfect," and smiled as he saw her blush hard.
