Having her in this position filled him with joy, and made him want to continue further, pushing this to it's limits. "I was going to let it slide this time, but since you mention it... As a matter of fact, Yes. Toilets don't wear clothes period." When the last words came out of his mouth, Alice's embarrassment doubled down. "I... You're right, Why do I even have these?"
Alice attempted to pull her shirt off, having some issues. Jeff watched and waited for her to take it off, but it seemed like she didn't know how. "You need a hand?" Alice stayed quiet, blushing as she nodded her head. "Alright, I'll help you get it off."
Jeff walked over to her, and pulled her shirt off of her, exposing her bare chest to the cold air. Just the sight of this gave Jeff another erection, and he moved down to her crotch, taking her skirt off for her. As he finished helping her, she handed her clothes to him. "I don't know what you plan to do with them, but it's none of my concern."
He sat there and admired his sister's sister's naked body; The thought of her wearing no underwear previously made him excited, but now he can actually see it all without anything in the way. Alice snapped him back to the real world, however; "Are you just going to stand there all day, or is there something else?"
