Natsu to Hako 1

Yoshi is walking along a mountain path with a butterfly net and cage in hand when he notices an unfamiliar girl in a phone booth. The girl notices Yoshi looking in the direction and calls out to him. The girl's name is Sachi, and she seems to be having trouble getting through on the phone. Yoshi can't leave her alone and enters the booth. But then the butterfly net gets stuck in the door, preventing him from getting out. To escape the heat, Yoshi takes off his clothes. Sachi hesitates, but she can't stand the heat and takes off her clothes. Yoshi notices Sachi's figure and becomes sexually aware of her. An insect flies out of the insect cage Yoshi is holding. Sachi panics and embraces Yoshi. Yoshi is struck by the softness of Sachi's body...
