Story:
For some reason Saori, the older girl I grew up with,
calls me "oniichan" (big brother).

At some point Saori developed into a super hottie.

Her erotic body throws off sex vibes...
I figured she was out of my league by now.
But her she is in my house.

W-why is Saori sleeping on my bed in her school uniform?
Wh-whyyy are her breasts exposed?

Guh! It's too hot! I can't... it's...

What's this? I love being taunted by her! Am I a masochist?
Yes, Saori, put on a swimuit and stroke me with your feet!
No, Saori, I vow I will not cum!
You want to watch me in the bathroom!?
I... I'm a virgin, why are we jumping to the extreme stuff?

Here is my detailed account of the last three, happy? days with my childhood friend.
