In this adult family-role fantasy, boredom at home leads to an unexpected trip with my mother and her two busty friends. For some reason, everyone enters a mixed hot spring together. Seeing huge breasts up close for the first time gives me an erection. The two women notice and tell me it would be better to let it out, then begin stroking my cock. Without letting my mother find out, they keep playing with me and make me ejaculate repeatedly, turning the getaway into an unforgettable trip.
