皮可秒

Evening, has had the dinner, we trade You Yi to go to the gizzard shad immediately to cure the hot spring, in the warm artificial pond has many "cherishes one's relatives the fish", I sit on the chair, puts in the pond the foot, calmly waited for 15 seconds, the small fish to flush to me, nipped my shameless, two, many strip, the small fish pecked me, might itch really.
