Ever since we got married, I've never been satisfied with the sex life with my husband, who is often away on business, so I ended up having sex with him a few times when he came to sell us household goods...I thought it would just be a little flirty...But I realized that this kind of relationship was not good, and just as I was about to stop it, my father-in-law, who is usually away at a city gathering during the day, saw us...Well, it was my fault...And that night, things began to move in a big way...
