A helpful houseguest

The next day you're sitting at your desk, working from home while still trying to process everything that happened last night. You hear the sounds of Emma leaving for work, but she doesn't acknowledge either of you before heading out.

As you continue to type away on your laptop, you look up to see Ashley standing in the kitchen pouring herself a cup of coffee. She was wearing only a cropped white t-shirt and blue panties. They both fit in a way that seemed intended to draw your eye, the shirt somehow loose, yet hugging every inch of her breasts, and the panties, although modest, followed every curve of her pussy lips.

"Good morning," she greets you cheerfully. "You want some?"

"Sure," You reply, even though coffee was the furthest thing from your mind.

She saunters over and hands you a steaming mug before perching on the edge of the table, her shirt riding up, exposing even more of her skin.

"So..." She starts, leaning back to rest her hands on the table. "I'm feeling kind of guilty."

"Guilty?" You repeat nervously, taking a sip of your coffee. Your mind immediately goes to last night and wondering if she is thinking about coming clean with Emma.

"Yeah," She laughs lightly, nodding her head. "I just feel bad for not being more help yesterday."

She stands up and starts pacing around the room, her ass bouncing with every step. It's clear telling her sister is the last thing on her mind.

"Well actually..."
