My wife Leg locked me and kept riding me even when I told her I was about to cum

Ok so me(27M) and my wife (33F) got married 2 years ago. She's been wanting a baby for 6 months. She just kept mentioning it and she says that her biological timer is starting. So I kept saying no. So well a month ago my wife and I were making out and it escalated to us having sex. So during it I had a condom but after a while she told me to take it off so she could suck it so I obliged so she later me down and she was sitting on my thighs as she stroked me then after a few minutes I said I was about to cum she then moved forward on to my dick and started riding me I told her to stop and tried to move but she just kept going then she went faster then I did and she was smiling and she finally got off. I was pissed and asked why she did that and she said that she couldn't hear me. But after a talk we had she apologized and we were fine. But a few days ago we were at it again she was laying down and I was about to cum and she said that she wanted me to tell her when I was about to. So I told her then when I tried she rapped her legs around me and I tried but it happen and it all went in her so when she let go I was pissed and went to the bathroom when I came out she broke down saying that she just wanted a family. So now I feel bad but she shouldn't have done that right.
