While my daughter's absence, my daughter's boyfriend makes me cum so embarrassingly...

Hikari lives apart from her husband. Sexless days continue. One day, I saw my daughter having sex with her boyfriend, and something shaking in my mind. While my daughter was away, I met my boyfriend again after coming to retrieve something I had forgotten... "I've been wondering about my mother for a long time. I can't stand it." My adolescent sexual desire explodes, and my big breasts and arousing body are pissed off. No... I'm definitely not going to cum...! Even though I was thinking that way, I was so embarrassed I was made to cum so much that I betrayed my daughter and had sex with her.
