Adult kissing sex with saliva threads intertwined

We are a married couple who have been living their lives managing the apartments left by our parents for 10 years. My husband doesn't help me anything and spends his days feeling cold, but the only person who gently speaks to me is Adachi, a university student who is a resident. He always cared for me while I was working... He smiled and smiled when I saw my happy face, and despite my age, I was moved by my heart, and even though I knew it would be unforgivable, I ended up cheating on him for the first time in my life with a younger man.
