Anne

The door opened just after I managed to close the shower curtain far enough to be well hidden but open enough to still see most of the bathroom.
Anne entered the room and shut the door behind herself, then went to the laundry basket and looked in the smaller one next to it, presumably searching for the dildo.

"What the....?", my cousin said to herself after unsuccessfully searching through the small basket. "I'm sure I left it here." She then looked through the laundry basket and after finding nothing looked around. I hid further behind the shower curtain to not be spotted and heard Anne move around more, searching for her dildo.

"Ahh, damn it!", Anne quickly got frustrated with her search and gave up. "Whatever, I'll search it later....and now, you!" For a moment I was shocked, thinking she knew I was here, but when nothing happened I moved again to look back into the bathroom and saw my cousin undressing.

She just pulled her shirt over her head and dropped it to the floor. She had laid out a very nice looking lace bra in front of her, which she must've gotten for her birthday and wanted to try on. I almost gasped when Anne unclasped her bra and let it fall, revealing her breasts. Barely keeping quiet I admired the side of her breasts, hoping she would turn slightly so I could spot a nipple. My cousins breasts were big and almost perfectly round from what I could see.
Anne picked up the lace bra and put it on, then moved her body a little from side to side to admire herself in the mirror. This gave me the chance to see more of her almost naked upper body and especially her breasts, that were now behind an almost see-through lace bra. My cousin was looking sexy as all hell and I now noticed that I had a full on boner.

Jus then I thought about the smell of the panties in my hand and felt like I just had to smell it again, so I did. Unfortuantely I brushed the shower curtain and , in an attempt to hold it in place to not be seen, I dropped the dildo, which landed on the bottom of the shower, audibly. My cousin spun around and looked confused towards the shower, as I quickly hid further behind the curtain.
