AP-134 On a family trip, my sister's defenseless big breasts were right in front of me! We were a single-parent household and not exactly wealthy, but my mother splurged and we decided to go to a hot spring as a family for the first time in a while! As we were sleeping side-by-side for the first time in a while, my sister's yukata, which she had been doing in her sleep, came undone, and her big breasts spilled out, just inches in front of me!

My family, a single-parent household, is not particularly wealthy, so we went on a family trip to the hot springs. It had been a while since I'd last slept in a row, but my sister's yukata, which she wears while sleeping, came undone, revealing her huge breasts! I'd never really paid much attention to it before, but now that my sister's unprotected, busty breasts were just inches in front of me, I couldn't resist! Before I knew it, I was squeezing and attacking her breasts!
