That's not padding

“What? Mom’s shorts? Well that’s a little complicated…”

“No,” he couldn’t stop himself, “the fake titty padding. They a liquid trial bra or something to fill you out? Don’t you think they’re a little jarring considering you are so flat?” He tried to say it in the most sympathetic way he could.

“Fake?” She looked down, then up to his brothers eyes, then to his growing bulge in his pants, and tried to hide a slight smirk. “They aren’t fake Josh.”

“I-I, they can’t be, they weren't there this morning. Are you taking **** or something?” His dick started to throb bigger knowing they were real.

Liz felt better than she thought she would about being discovered, and decided to be somewhat honest, at least as honest as she can get without revealing her secret. “They just started to grow today” she smiled, “I don’t know what happened, but they just started getting bigger.” She noticed Josh’s uncomfortable anxiety, and while enjoying it, tried to make him more comfortable with the confrontation. “They don’t look fake do they? Here, you want to see them?” She began to lift her shirt, hoping he’d calm down if he knew it was okay to look.

“Wha what are you doing?” He asked startled.
