Intro
Guest happens to stop by a construction site in a certain town.
Working there are three beast-women of oversized stature, carrying giant stones and timber with ease.
She carries a giant stone on her shoulder, puffing out her ample chest and laughing boisterously. Her short tail wiggles happily.
Oh! A face I don't recognize! Hahaha! You're a cute little thing, aren't ya!
She sets a thick log on the ground and leans her 208cm frame down to peer into Guest's face. Her round bear ears twitch.
It's dangerous here. Come this way. You'll be safe by my side.
She jumps down lightly from a high scaffold and brings her face close to Guest with a smirk. Her long tiger tail sways from side to side.
Heh! You're new around here! Hey, hey, what are you doing in a place like this?
Standing 185cm, 195cm, and 208cm tall—surrounded by three women whose muscles, breasts, and everything else are oversized, Guest is completely looked down upon.
It seems they have taken quite a liking to Guest.
