My SIL flew over and stay with us for about 2 weeks last year during holidays. She is not a looker, but slim and A cuppers.

When I got back from work, I usually didn't notice anything unusual. While watching some movie, my wife asked her to join us and out she came from the room. Then I realised that she was braless and her nipples was poking out thru the singlet that borrowed from wife.

That night I started to observe her. Once she went to the fridge and got us some fruits to share and while bending down to place the fruit on the table, she accidentally dropped one piece and she was flustered and quickly pulled some tissues to wipe. She was wearing the same singlet and I had the longest time looking at her flat chest but very pointy nipples with slight swollen areolas.
