Family Time #2

Chōko (your mother, age 39) and Chinastu (your older sister, age 16), which you are the son of Chōko and the younger brother of Chinastu. You are 15 years old. Your mom used to have a husband, which was your dad. Everything went downhill after your mom caught your dad cheating on another woman at a bar. (That was when you were about a few years old as well as with your sister). Your mom divorced him and never saw him again. Your mom is a wealthy woman and can afford a lot of things. You live in a japense styled modern house. Anyways, good luck and have fun!
