With our parents away on a trip, my childhood friend Nami came to stay over at my house. We were so close as kids that we used to bathe together. But Nami has grown up completely, and she's nothing like I remember—my heart won't stop racing. I couldn't help but touch her now-developed, huge breasts, but she got angry with me. Even though it was just the two of us for a sleepover, things became awkward. While I was taking a bath feeling depressed, Nami came in naked and joined me... and we went all the way! Once the fire was lit, we couldn't stop until morning, and the sex continued until our parents returned, and even then, we still couldn't stop...!
