I went on a hot spring trip with my nieces whom I hadn't seen in a while. Wanting to see their grown-up bodies, I peeked at them changing clothes and got caught, so we ended up bathing together. One of the nieces grabbed my dick playfully while pretending to wash herself, and it seems she's getting excited by my erect penis. After being alone together, we secretly returned to the hot spring and remembered the mischief I did to her vagina before. While washing each other, our lust exploded, and in the bath, I made her deep-throat my dick. Then I fucked her overly wet, smooth pussy.
