Milly has her own naughty idea

"You know," Milly started out as she stared at Hilda's nearly naked form. "Those panties of yours look awfully nice."

"Yeah, they're real spidersilk,"said Hilda as she smiled at Milly. "You wouldn't believe what I had to do to get them."

"Do you think it's wise to keep wearing them?" Milly asked.

"What do you mean?" Asked Hilda, feeling concerned about her most precious possession.

"Well, I'm just saying... you're walking around outside with them exposed to the world. Anything could happen to them. They could get damaged or stained. Who knows, you could even lose them," Milly said, biting her lip. "Maybe it would be better if I held on to them... for safekeeping?"

Hilda bit her lip and suppressed a moan as the collar on her neck glowed. "B-but then I'd be naked."

Show everything you've got. You were meant for this.

"So?" Milly shot back. "It's just us. No one's going to judge you."

Serving feels good. Listen to mistress.

"Yeah..." mumbled Hilda, the collar flashing once more as the back pack came off.

"Besides have you ever gotten naked outdoors? Felt the air on your body?" Milly was blushing a little herself. "It's quite exhilarating."

You want to feel good.

"Mmmmm," Hilda groaned as her hands slid down to her hips, pulling her panties down with them and exposing her hairy bush. A thin string of slime bridged her soiled undergarment and freshly exposed pussy before it finally broke.

Hilda stepped out of her last (and rather fragrant) possession and gave it to Milly. "Here..."

Hilda's body was trembling with arousal. She could barely stand as she once again grabbed Milly's bag.
