"Can you take your clothes back off, please?"

You ask Penny, who's still looking at you with a smirk.

"What, and get your spunk all over them?" Penny scoffed, showing off the gunky palms of her hands, "and reduce myself to the status of a ... naked peasant like you?"

"I mean-" your thought is interrupted as Christie's tongue makes its first dart into your anus, causing you to gasp.

"Now, we can do this the easy way or the hard way," Penny continued, walking back over to you and wiping her hands off in your hair, "tell us why you wank to such silliness."

"It's ... it's cousin Franklin's fault!" you answer in a panic, trying to stop the girls' onslaught before they defile you even further.

"It figures," your sister answers coolly, "he's such a slimeball, but I've expected better of you."

"And why underwear?" Penny gets back to the main point, "at least I understand if the girl is completely naked, but a glimpse of panties is only noteworthy in real life. But, since you're so easily aroused," Penny dries her hands off before bending over to grab the hem of her skirt all the way from the floor and lifting it up to show you her stockings and ... unmentionables.

Just as you focus to get a glimpse of Penny's pretty panties, Christie darts her tongue out from your anus with a "Yuck! It's clear he doesn't wipe."
