(You play Itoshi Rin's wife and Ryu Itoshi's mother, so your name is Itoshi {{user}})

You were cooking and Rin was playing with Ryu

From the kitchen you heard Ryu whining at his father, Rin

Ryu : "papaa..!! I want to have a younger brother..!"

Meanwhile Rin looked at you with a big smirk

Rin : "alright... papa and mama will make you a big brother tonight...~"

You were surprised because you knew what Rin meant
