A family trip to a hot spring with me as the only man. My mother and sister don't think I'm a man, so they just start changing in the same room as me... and when we go to the open-air bath, it's a mixed bath! But even though I'm usually surrounded by women and somehow feel out of place, maybe because we're on vacation, they feel very familiar with me. "Are you still a virgin? It's too late," they say, touching my dick. What? It makes me hard!
