Yes, this was a good opportunity

Tangled together as they were it was a simple task for Walter to capitalize on the situation. As the two struggled to extract themselves Walter stealthily undid the buttons on the back of his sister's dress. At the same time he made sure to press against her breasts, thus distracting her from noticing his ungentlemanly actions. As they struggled Charlotte's dress only became more and more tangled, riding up and exposing her long legs and light blue knickers. Thanks in part mostly to him tying and trapping her clothes as they squirmed.

"You're looking rather improper sister mine," Walter chided in a quiet voice. Before his sister could reply he shushed her. "Don't make a fuss. It wouldn't do for Uncle Thompson to see you in such a state."

His sister glared at him. "Then stop struggling and let me free myself," she hissed in a low voice.

Briefly taking advantage of the lull in struggling, Walter was able to divine the root of the problem. "It's not my struggling that's keeping your trapped. Your dress is stuck."

"Unstick it then," his sister said quietly.

"Don't complain when I do then."

"I won't."

"I'll hold you to your promise," Walter said with a smirk. Now that he had a ticket to do as he liked under the guise of freeing his sister he began the arduous task of undoing all the meticulous ways in which he had messed with his sister's clothes. The first thing he did was undo her brassier and slip it off. His sister started at that and turned to glare at him. "Sorry, it was caught..." he said, offering an excuse that his sister nonetheless had to accept. Besides all he could see was her smooth back. It wasn't like he had stripped her topless since she was still wearing her dress, albeit with a little more freedom for certain parts of her body.

His sister wasn't free yet so Walter took the opportunity to slip his hands down the back of her dress and grope her soft butt and thighs. He felt her shiver a bit as his hands drifted from her butt towards her crotch, however, he pulled them out before touching her there. As his hands slid out his sister let out a little sigh of relief. Or at least Walter assumed it was discontent at first. But as he looked at his sister's face he could see that she was slightly flushed. Her eyes wouldn't meet his and she was biting her lip as if she wanted to say something but had decided not to. Maybe it was discontent then?

Still, his sister was now freed and so Walter stopped his roaming hands. Charlotte huffed. With an awkward smile Walter poked her cheek. "I didn't go to far did I?"

Without a word Charlotte grabbed one of their suitcases and repositioned it to take up most of her seat. "It seems as if their isn't enough space," she said in an emotionless tone. "I'll have to sit on your lap." Upon saying that she adjusted her position and plopped herself down in Walter's lap. "Ah. It seems that there's something tangled in the front of my dress. Could you fix it?" she continued in the same dry tone.

Walter sighed and slipped his hands into the open back of his sister's dress and rested them on her soft tummy. "Where's the tangle?"

Charlotte didn't look him in the eyes but just tapped her chest. With a shrug Walter ran his hands up to his sister's bountiful breasts. He wasn't sure exactly what to do but he wasn't a man who would throw away an opportunity. Her breasts were soft. Mostly at least. As he fondled her and stroked her areola he noticed that her nipples were very much not soft. He gave them a pinch.

"That's far enough," his sister huffed.

With a sheepish grin Walter retracted his hands and buttoned up his sister's dress before holding her by her waist. "Sorry sorry." The two fell asleep embracing each other. They were soon awakened when their car pulled into the sizable mansion that belonged to his mother’s brother, with whom they would be staying. The two siblings were unloaded and quickly shown to their rooms. Walter thought he heard something about his other Uncle, the one who’s house they were staying at, greeting them in the morning, but Walter was too tired to truly listen. He didn’t even bother removing anything more than his jacket, and just collapsed onto the soft sheets. As young men are wont to do, he could function for a long time without more than an hour or so of sleep but this was pushing the limit.

"Hello." The man greeted Walter as he found himself standing upon a great clock once more. "You have taken the first steps on your journey. Did you use the watch? Who did you use it on? What resulted? So many possibilities, so many paths, so many results. Usually one would say that your actions have consequences, but that has a negative connotation. Rewards is a better way to phrase it."

Standing, as the two were, on the center of the clock, the many hands that spun around them came to a halt, each one leading into a portal of light, like pathways radiating from a dais. The man gestured forwards. "Choose a path forwards. Or backwards, if you'd rather. I believe you've noticed by now, but we are rarely picky about time here."
