Erotic Lactation

So one day my wife and her sister decide to call me over to the living room, her sister was pumping,as they laughed my wife insisted I try breast milk to see what it taste like.so her sister hands me a cup with a little bit of her milk in it and I sipped on it . As I sat there tasting it i couldn’t get the image out my head I was sucking on my sister in laws t!ts.. I acted like it was nasty but truly it was tasty and I got turned on so much from it.later on I confessed to the sister I enjoyed drinking her milk and I was sorry if I made her feel bad. She looked at me awkwardly and she said that she has plenty to go around. So here and there she leaves me a bottle in the fridge and tells me that it’s for me. To long of a story to explain but , it got to a point where the sister and I would foreplay with her breast milk .
