Not sure about a swinger club, more like a hotel room where she got shared. Either way, good wife with great tits allowing herself to be shared like that.
The first time l took my lovely bride to a swing club was on our second wedding anniversary. She left me with a vision of her in a white silk sequined robe. The sash was loosely thrown over itself once. That left an abundance of well -tanned cleavage between her pert, 34C's, augmented with a nice necklace and matching earrings. The robe left half a creamy butt cheek descending from her 35 inch hips. To my delight she went sans panties, her pubic region coifed by yours truly in a tasteful landing strip. All of this set off with white high heels. You could hear a pin drop when she slipped out of the robe. All eyes were on her, My Trophy Wife!
