I expected a trip with Mom, but two busty neighborhood friends joined us. Shy and nervous, I ended up sharing the hot spring with both women, and their breasts soon got me hard. They played with my cock until I came hard, then took me to the outdoor bath and bedroom, smothered me between their tits, rode my cock, and let me spray cum over their breasts, faces, and pussies. It turned into the happiest vacation of my life.
