I suddenly decided to participate in a hot spring trip with my mother and two mom friends. And to enter the mixed bathing hot spring together. Two of my mom friends have very big boobs, so I got excited and got an erection. My mom friends thought I was cute, and they hid me between their breasts so that my mom wouldn't find out (I guess they didn't find out...) and played with me comfortably as a toy. It was a very enjoyable trip.
