Group vacation at the beach in a VRBO. I was taking a shower in a “shared bathroom” between my room and their room. She woke up, her husband wasn’t in bed, and she came into to use the restroom (I guess assuming her husband was the one in the shower - I found out later he was out for a run). I opened the shower curtain to see who had come in and she was sitting on the toilet in nothing but a tank top. We made eye contact, she said oops and half ass covered herself up, finished, and went to leave the room.

I had a thing for her for years and seeing her bare ass walk away in a thong I said screw it, told her she had a great ass and there was room for two if she was interested.
