I was suddenly asked to join my mom and two of her mom friends on a hot spring trip. Then, we all went into the mixed bath hot spring together. The two mom friends have very large breasts, which made me excited and erect. They thought I was cute, sandwiched me with their breasts, and hid me so that my mom wouldn't notice (I hope she didn't...), then played with me as a toy and made me feel good. It turned out to be a very fun trip.
