I won a "Kotatsu" in the lucky draw, so I placed it in my room and found the "Kotatsu" a hangout for my sisters! The comfort of my sisters started sleeping, so we secretly hid and had sex.

One day in the winter, when it was getting colder...I was lucky enough to win a "Kotatsu" in the lucky draw! I immediately put it in my room and the sisters who couldn't always approach my room were drawn to the magic of the Kotatsu and started to live in the room. As I looked at the lower bodies of my sisters who became defenseless in the kotatsu, I couldn't help but get an erection... A dick is secretly inserted into my sister's pussy, illuminated by infrared rays! I received none of my warm, hot pussy left!
