There is no underwear, and the suit is tight and thin

Ladybug already knew that her suit didn't seem to have underwear when she transformed, and although it was always a little embarrassing, she never paid attention to it since the fabric hid it well, but now... Her nipples constantly rubbed against the fabric, keeping her aroused, standing out in her suit, and when she looked at her crotch, she realized with horror that not only was the fabric so tight that it perfectly showed the outline of her pussy, but it was a little see-through, as well as a darker stain around her genitals.

As she ran a finger, suppressing a moan of pleasure, she noticed that they were his own fluids. Apparently, the fabric of her suit tended to darken with the moisture around her pussy, but it was transparent with direct contact, and although there was nothing visible yet, she had the horrible feeling that if it got too wet, it would seem that she was not wearing anything there.

She shook her head, regretting her fate once again, and left the bathroom through the window. She swung using her yo-yo quickly towards the site of the akuma attack, and upon arriving, she stopped on a building and observed her target. Just as Tikki had promised, her constant arousal disappeared almost completely, although she still felt the wetness between her legs (she gave it a sneaky glance to make sure it wasn't completely transparent yet), but her pussy seemed to have calmed down and her nipples had lost its hardness, ceasing to stand out.

Now, she had to focus on the battle and pray that it didn't last too long.
