It was Christmas dinner and hubby (m50) and I (f41) attended the family dinner at a restaurant…my petite Italian niece was there, who has some sexual history with us… she’s married and outgoing and her hubby turns a blind eye to her shenanigans. Tonight was no different…the restaurant was packed with tables close together causing people moving around a bit difficult… She got up and was moving around to me…hubby got up to get drinks…she squeezed past him…her body up against his…she looked up at him…a big smile as she said excuse me…he put his hands on her…his fingertips grazing against her perky breasts… She leaned in to whisper to me…that it was so hard…to move around the table…and I saw her grinding her ass into his groin… he spanked her ass and she yelped…still grinning at me…
