I (M34, married) have a neighbor (F34, also married). So to make story short - she's always been chatty-flirty with me, but recently things are going a little bit more intense. Two days ago she invited us to a birthday party of her son. Our kids get along very well together. Since there were other guests (including my wife and her hubby), and she was busy taking care of a party, we werent talking much. However anytime when noone watched, she kept giving me meaningful stares and smiles. Meantime I told everyone I'm going upstairs to check how our kids are having fun. She immediatelly got before me on stairs, and in a halfway she "accidentally" dropped something. OMG - she was wearing loose, short sundress and when she leaned, I saw her white cotton panties just a little bit to the side so one of her lips stayed a bit uncovered, and with a wet spot on the middle... 🙈 what a view! She stood up after a good couple of seconds. I immediatelly got hard, hoping noone could see it. Once we got back downstairs, I couldnt focus on anything else, having this view in my mind to the end of the party. When we got back home (we live next to each other) I got my kids to bed. But what I saw right after, totally blew my mind 🤯 she started taking a shower in their upstairs bathroom with curtains open (which used to ALWAYS be closed!). After she cleaned up her petite, short and amazingly hot body, she started playing with shower head on her pussy 😱 she also played a bit with her small perky tits and nipples. I know she knew I was watching, since after she took a shower she smiled while closing the curtains. She messaged me immediately right after thanking for coming and great gifts for her son, like nothing happened. What would you guys do? It makes me feel horny and guilty at the same time everytime I think about it 🙄
