First day meeting adopted little brother and she shows up without pants and already wanting to jump his body. Those are some good thirst impressions.
She is being a hikkomori and hadn't meet anyone aside from her parents. It won't be surprising that her libido is off the charts.
He...hehe.He...hello...We...we'll be...we'll be family...from today onwards...Pl...please don't...be on guard...around me.
Onee-chan
You can call me that.She's my step-sister, my step-mother's child from another marriage.
She seems like the shut-in type. I'm a bit nervous since I'm suddenly living with an older female...
...Her boobs are huge too...From now on this kid will be mine.So cute.
