Yes, but it's a little different this time

He went back and forth in his head about whether he had the courage to do what he needed to do, and ultimately found himself standing above her bed. He knew the heavy sleeper wouldn't notice him there unless he made a loud and sudden movement. He gently grabbed the waistband of the shorts and pulled them down to her thighs. There they were, a pair of white cotton panties on top of his sister's pussy. He had never seen it this close up before and felt his dick straining in his shorts. He took a deep breath and pulled them down to reveal her pussy. She clearly cared a lot about how it look, he could see that it was cleanly shaved apart from a small bush right above her slit.

He focused back on his original target, and saw that the crotch of her innocent looking panties was once again, soaked. She must have been playing with her pussy in bed, probably replaying the events from earlier in the day. Alex turned his phone's camera toward the panties and took a closeup shot of the crotch, using flash to make sure the set spot was as visible as possible. He then took one last look at her cunt and pulled the clothes back onto her and walked out out of the room.
