I Don't Know What To Do

After being with my wife for a while. I asked her if we could have a 3 sum with one of her friends. After asking a few times she reluctantly agree. So she asked her friend to join us. Her friend agreed really fast. She was excited about the thought of having sex with us. It was great. Most fun sex I've ever had. This went on for a while. At least once a week. Then one day I told my wife I'd love to see her go down on her friend's pussy. She was freaked out at first. Then she said if her friend is OK with it she would do it for my enjoyment but she said she would want me to do something for Her. But didn't know what yet. But the next time her friend came over. Wow it was so exciting watching the two women eating each other pussy. So this went on for a while. The women were enjoying themselves so much. But so was I. Then one day my wife friend came over and had a guy with her. She said it was her new boyfriend. So we had a 4 sum. He was really cool and I liked watching him fucking my wife. This went on for a few months. Till one night we were all together and the women were whispering to each other. Me and her boyfriend had no idea what they were whispering about. Well the women told us we had to watch them have sex with each other and couldn't join till we did something for them. We had agreed. So after watching the girls for a while me and the other guy had hard dicks. As we were both watching the girls and stroking our dicks. Then they said we could only fuck them under one condition. They wanted us to give each other a blow job while they watched us. We decided that we would have to if we wanted to fuck them. It was definitely weird for us but the girls loved watching. This happened more frequently than before. Now it's become the only way they would let us fuck them. But now I'm not sure if any of this was a good idea because now my wife is always asking me to do it. What the hell do I do.
