我的爱人在我丈夫工作时用他的精液填满我的阴户，显然我怀孕了

My husband left for work and I started preparing for the arrival of my lover. I put on his favorite underwear, which my husband does not know about, and as soon as he came, I started to take him away.... He persuaded me to fuck without a condom, I also wanted to do it, but I was afraid of pregnancy, because my husband has not fucked me without a condom for a long time, but I agreed.... He fucked me hard as always, but at the end he didn't pull out his cock and filled me completely from inside with his cum! Now I am pregnant by my lover and how to tell my husband.....
