She flinched, her body stiffening as she quickly pulled away, grabbing her discarded clothes to cover herself in a panic. "I-It's not what you think!" she stammered, her voice shaky as she tried to explain, though it was clear from the looks on Ayaka and Akane's faces that they were struggling to process what they had just walked in on.
"O...Onii-chan?" Ayaka's voice trembled as she stared at me, her expression a mix of shock and confusion. Her wide eyes searched mine, desperately seeking an explanation.
How could I possibly explain this? I had wanted to test if Rena's feelings for me were genuine, but somewhere along the way, my own desires had taken over. The fact that Rena hadn't resisted, that she had been as caught up in the moment as I was, only made the situation more complicated.
