Dad again

"I'm going to go to bed early," Lily said, her eyes darting up to their father before falling back to her plate.

"Yeah, me too," Matt chimed in, "I'm still not feeling 100%, and I could definitely use a good night's sleep."

"Well, you'll both have to get the dishes done first," their dad said, "I'm sure if one washes and the other dries, it won't take too long."

Oddly enough, Lily didn't object, and Matt was too preoccupied to speak out, so the rest of dinner passed in relative silence, Matt watching as Lily and their dad exchanged glance after glance. After they all finished, Lily stood up and started putting the leftovers away, and Matt gathered the dishes while their dad went into his study after stopping at the refrigerator for a fresh beer.

Lily washed while Matt dried, and as he stepped behind her, he couldn't help but look at her. Like his mom, he had never thought of his sister as a sexual being, but the events of the day had opened his eyes to the world around him. His twin had their mother's looks, with a youthful look, thinner body and smaller breasts, she gave a look at their mom's teenage years. For a moment, Matt was tempted to jump into her, just for a moment, in order to try and get her to strip down for him, or maybe come into his room after everyone was asleep, but his curiosity about the looks on both Lily and their dad's faces during supper.

After she was finished washing, Lily drained the sink, and walked out of the kitchen without a word. Matt finished drying and put the last of the silverware away, going to their dad's study and knocking. "Dad?"

Matt heard the desk chair squeak, and his dad clear his throat before responding, "Yes?"

"I think Lily went to bed, and I'm headed up to my room. Night," he replied, trying not to let his nerves rattle his voice.

"Okay, Matt, sleep well."

He went up the stairs, heart pounding as he walked past his sister's bedroom near the staircase, their parents' bedroom door directly across from it, then the bathroom door between his room and Lily's room, and into his own room, closing the door. It was a struggle to lay still, but being the furthest from the stairs, he didn't want to act before his dad came up the stairs.

Not ten minutes later, Matt heard his door creak open. Knowing he shouldn't hold his breath, he **** himself to breathe deeply as if he were asleep. The door creaked shut, and he could hear footsteps withdrawing down the hall. Matt counted to twenty, focused on his dad, and jumped.

He didn't know what to expect when he jumped, but what he jumped in to was nothing he could have ever expected. His hand was behind his back, closing a door without looking back. His eyes were focused forward, where his sister Lily stood. She had apparently braided her hair since supper, the braids laying over her shoulders and down her arms, which were being held against her sides.

She was also completely naked. This was the first time Matt had seen her naked since the two had been little, and although he had intellectually known she had grown, he had never dreamed she grew up like that. His eyes almost drank the sight of her body in, moving from her perky breasts, down her flat stomach to her shaved pussy, then back up her body. After a moment (or a thousand years, he couldn't tell), his gaze slid up to her beautiful face. Her expressions during dinner had been unreadable, but the expression over her naked body was easily understood.

Her face showed pure...
