Slut Wife young BBC

My wife Shay has been with two different bbcs now one was a friend the other was someone she met at a bar. She is totally addicted to doing this now and talks about it frequently. Both times she did it she orgasmed over and over again. The last time it was a friend of ours Jeff who she teased and won’t let enter her right away. When she did then did and they had wild sex for the next hour as I watched. He came three different times and then rested on the bed and she would suck him off or give him a handjob to get it going again and the last time he came in her which she just went nuts over. I was kind of in shock I’ve never seen her this morning and acting like a little slut . After he left I too fucked her and came in her pussy. She talks about this almost daily. She wants me to call Jeff and have him come back again and she even inquired about him coming over when I’m not home and I come home to her come filled pussy. He told me she almost called him yesterday for him to come over so I could come home to a surprise. The thought of this turns me on. Am I Wrong to feel this way? Here are some pics from 2 weeks ago with Jeff. More taken..
