Vibrating panties

The clothing she was given was a single pair of panties. “Strange...” she said to herself while putting on the panties. “This isn’t one of my pairs. Still, at least it’s something to wear.” That’s when she heard a noise from the kitchen.

“Huh?” said Sonic as he emerged from the kitchen. He was holding his late night snack, a chili dog in his hand. “Is someone there?”

_Crap! _Sally thought, hiding behind the captain’s seat. Sonic must have heard me! I can’t let anyone see me like this! Maybe if I be quiet he’ll go away.

As Sonic was looking around and Sally sat there, waiting for him to leave, she felt a sudden stimulation in her nether region.

“Mmmmm...” Sally moaned quietly to herself, only to abruptly cover her mouth. _Wait, a second, these panties are... Oh no. _She peeked around the corner to make sure Sonic hadn’t heard her. Luckily, he was still oblivious to her location, still looking around the room. It’ll be much harder to hide with these on! Still, I can't just get rid of these! They're the only cover I have! I'll just have to keep quiet.
