SW-278 Mom and Dad Came to Tokyo Worried About Their Son Who Lives Alone. It's a Hot and Humid Night, But the Air Conditioner Is Broken, So It's Stuffy in My Room, And Mom's Body, As She Sleeps Next to Me, Is Soaked and Sweaty!

Mom and Dad came to Tokyo, worried about their son who lives alone. They decided to stay at my house, but the air conditioner was broken, so it was extremely hot and humid inside the room. I suddenly looked next to me and saw Mom's clothes were transparent with sweat, which excited me! Her nape and back were soaked with sweat! Her nipples were also visible! Even though I knew it was wrong, I got an erection from Mom. Has Mom noticed something strange?
