My sister in law is amazing

A little back story so my sister in law ( my wife’s brothers wife) hangs out with us a lot while my wife’s brother and I hang out. One time after drinking we all went to sleep and I had sex with my wife in our room. The next morning he told me they could hear us and they heard everything and that my sister in law got so turned on listening to us. He said she got wet and playing with herself wanting him to fuck her while they were listening to us. He said he got grossed out because that’s his sister. She ended up pleasuring herself to us having sex and after cuddled up with him and went to sleep.

Fast forward a few weeks later we were all hanging out drinking and started talking about women and how hot some of women we know are. When my brother in law drunk whips his phone out and shows me picture of some big tits and another of an ass both were of the same woman. I said nice shes hot, he leans over and said that’s my wife. I couldn’t believe I saw a picture of the woman in the next room that comes over all the time naked. I instantly got a boner and kept looking over knowing I know what she looks like naked. We ended up getting black out drunk but in the back of my mine was my sister in law. He was blabbing about something and went to show me another picture but this time he handed me the phone. As I looked at another nude of my sister in law he slumped over on his chair and fell asleep. I scrolled and saw another nude of her. He was snoring now and I dont know what came over me but I sent all her nudes to my phone. I put his phone on the floor next to him and send the hour looking at all the pictures I now have. I have conversations with but all I can do is picture her naked.
